Denmark was building the world’s largest wind farm when a 400-year-old sunken ship was found

by

Although we have been watching for years how China builds renewable mega-facilities like It is on the Tibetan plateau or this other colossal wind farm with 136 wind turbines 100 kilometers offshoreis not the only country with great ambitions to generate clean energy. Without going any further, Denmark is in the preliminary stages of setting up the largest offshore wind farm in the world, Hornsea 3. But for now this installation will have to wait because in the middle of prospecting work, they have found gold. Or rather, lead: the one reveals the existence of a wreck with a cargo of lead ingots. The discovery. This huge wind farm is being installed by the energy company Ørsted, in the North Sea, off the coast of Yorkshire. There, about 120 kilometers from Norfolk and about 40 meters deep, they were doing safety surveys of the seabed in search of possible unexploded ordnance from the Second World War when they came across a 17th century shipwreck. The curious thing was the trigger for such a discovery: what appeared on the monitors were three lead ingots weighing 70 kilograms each that were still stacked in their original position. There were also some remains of wood and some hull of the ship that transported them. Thanks to the mark that the smelter left on the ingots, it is possible to try to trace their origin, in this case of hypothetically linked to Derbyshire. Why is it important. Because it clearly evidences the early modern English lead trade. In this case, the wreck found is directly on the route that linked Hull with the Netherlands through the North Sea. Context. At that time and as the MSDS Marine explainsEngland produced large quantities of lead, especially in the mines of Derbyshire and the Peak District. From Hull and London it was exported to other locations, such as Amsterdam and Rotterdam. Before we discovered the toxic effects of lead, this element was commonly used for pipes, cookware, weapons, and other products. Transforming it into ingots made it easier to transport as merchandise. A curiosity: the heritage legislation of the United Kingdom requires archaeological studies to be carried out before the construction of this type of infrastructure and thank goodness, because in British offshore wind farms in recent years a roman anchor has been found. In detail. More specifically, the three recovered lead ingots have three different engraved markings (“IS”, “EB” and “H”). These signs are reminiscent of those found in the Kennemerlanda Dutch East India Company ship sunk in 1664 near the Shetland Islands. For this reason, in this preliminary phase the research team holds that the ship was probably Dutch and was heading back to the Netherlands loaded. Yes, but. At the moment, almost everything is hypothesis: a deeper investigation is needed to determine the origin of the ship and a more precise dating beyond the “17th century.” Furthermore, the geological origin of lead has not been analytically confirmed either.

The wind industry has been dreaming for years of a turbine that can be assembled without concrete or machinery. France has said ‘hold my cubata’

by

When we think about wind energy, the first thing that comes to mind is turbines with huge shovels that we usually see in the distance when driving on some highways in the country or the infographics of Chinese companies with XXL towers for marine plants. In France, a designer has decided to rethink those ideas and become a question: What if we could have a light, modular wind turbine that did not require complex (and very expensive) installations and was also recyclable and scalable, so it would be useful for both self-consumption and industry? The result is Wind to Watt. Wind power without megaprojects. we like them the megastructures. It’s no secret. That is why it is not strange that when we talk about wind (both onshore and offshore) the projects that resonate the most are those that involve huge turbines, gigantic towers and XL shovelslike the model of 153 meters and almost 90 tons devised by the Chinese company Dongfang Electric (DEC). In the sector, however, there are people who work with another approach: new modular wind turbines that make wind power popular at the domestic leveljust as it has been doing (for many years now) photovoltaics. Squaring the circle (wind). A few years ago the French designer Fabien Brun decided to move in that same direction, that of scalable wind power, asking itself some questions: Would it be possible to design a light, modular turbine, easy to transport, economical, recyclable and that also does not require complicated installations, such as concrete platforms capable of supporting large towers? They are not minor questions. Quite the opposite. They address some of the main challenges that wind power faces, such as how to make installations cheaper or what the hell to do with tons and tons of blades that reach the end of their useful life and are made with fiberglass, carbon, resins and other compounds that complicate their recycling. There are those who estimate that in 2030 only in Europe there will be more than 50,000 wind turbines that will have reached their useful life period, which is usually estimated at 20 years. The result: Wind to Watt. The result of those questions is Wind to Wattwhich is presented as “the first 1 kW wind turbine without the need for civil works, designed for mass production and global scalability.” Unlike conventional wind turbines, what Brun proposes is a light structure made of aluminum tubes and plastic canvas, which has two great advantages. First, it simplifies and speeds up assembly. Second, it prevents you from having to prepare concrete bases or alter the terrain before installing it. “Silent and minimal impact”. Those responsible for Wind to Watt also claim that by using tubes and tarpaulins it reduces costs, facilitates transportation and is manufactured with recyclable materials. They also argue that the generator can be adapted to any type of context, both on land and in marine parks, and that it does not generate noise pollution. “Its operation is silent and has minimal visual impact,” ditch from the company. What about power? The team ensures that their turbine is scalable and they offer six different models. The most basic and smallest measures 1×2 m, generates 0.3 kW and is designed primarily for residential use and self-consumption. The largest measures 10×20 m, has a power of 62.4 kW (more than 1,500 kWh/day) and those responsible assure that it serves to supply energy networks. Of course, in your catalog They include smaller models, 10.4 kW or 20.8 kW, theoretically designed for light industry or data centers. As far as prices are concerned, the company assures that the cost per kW installed is around 2,500 euros and its maintenance costs about 50 euros per year. According to the calculations of those responsible, it saves 500 euros per year and the investment is recovered after five years, a fifth of its useful life (25 years). What phase is it in? It still has a way to go to become a widespread solution, but those responsible defend the path they have already taken. “The company, which has been technically and commercially validated at an international level, is entering the industrialization and commercial structuring phase,” points out Brun, who insists that the turbine is designed “for mass production and global deployment without heavy infrastructure.” Their goal is to begin their pilot deployment this year.

León wants to start a biomass macroplant to heat 28,000 homes. The neighbors are afraid of something: the wind

by

“Mayor! Where are you?” The cry echoed this Wednesday in the central Plaza de San Marcelo. According to local chronicleshundreds of people responded to the call of the Barrio de la Lastra Neighborhood Association to try to stop the construction of the gigantic biomass plant planned in the south of the city. The point is that this is not an isolated march: the residents of La Lastra and Puente Castro have joined forces in a joint mobilization that reflects the fatigue of the southern neighborhoods in the face of an imminent environmental impact. But beyond the noise of the banners, there is a very specific fear. As Ruth Sanz explainsneighborhood spokesperson for La Lastra, the big hidden problem will come “when the wind changes direction.” The citizen warning is blunt: if the plant comes into operation, not only will the smell reach other neighborhoods in the capital, but the air will carry harmful substances. For this reason, with the motto of “our health is not for sale”, the neighbors demand that the excavators be stopped. The beginning of the indignation. To understand this social outbreak you have to look at the offices. As detailed in the specialized magazine Rethemethe project promoted by the Junta de Castilla y León and the City Council aims to create a “Sustainable Heat Network”. Through Somacyl, the regional administration seeks to build a thermal power plant that supplies heating and hot water to more than 28,000 homes and 150 buildings in the capital. However, the outrage also has a political component. As emphasized by Herald of Leonresidents directly accuse the socialist mayor, José Antonio Diez, of serious inconsistency: they remember that, when he was in the opposition, he led protests against a similar biomass plant in Cantamilanos, and now allows an installation that is seven times larger. Furthermore, the neighborhood anger lies in how it has been created. As revealed elDiario.esthe Board has processed this immense 22-hectare complex – located at the foot of the city, next to the municipal cemetery and the Torío and Bernesga rivers – under the controversial figure of ‘Regional Project’. This administrative movement serves, as this medium explains, to “shield” the complex, unify contracts through urgency, accelerate expropriations and avoid local urban planning obstacles. Green energy or environmental risk? Green energy or environmental risk? The project stages a head-on clash of realities. In the official discourse, it is the definitive ecological initiative since the administrations They defend that the infrastructure It is key to decarbonization. They promise that it will allow more than 1,200 fossil fuel boilers to be progressively turned off, will prevent the emission of 35,000 tons of CO₂ annually and will allow neighboring communities to save between 20% and 30% on their bills. The dark side of this “green promise” is provided by environmental defenders. As argued Ecologists in Action in their allegationsinstallation of these dimensions near inhabited areas is environmentally unsustainable. The entity warns that combustion at an industrial level will cause highly dangerous emissions, releasing “benzopyrene, heavy metals and particles” into the air. Furthermore, environmentalists throw down the argument of resource sustainability. The complex will swallow up to 128,000 tons of forest chips annually – a volume that threatens to overexploit the forests – and will consume a whopping 35,000 cubic meters of water from the urban network, without the City Council having issued technical reports that guarantee that this will not affect the population’s supply. Pharaonic figures and legal mud. The size of the project is difficult to assimilate without looking at the pure data. According to the technical data provided by Leon News, The horizon of southern Leon will be modified by the installation of four enormous chimneys 35 meters high (a level equivalent to an eleven-story residential block). At a logistical level, the activity of the furnaces will generate 4,480 tons of ash, slag and dust each year, and will cause an incessant daily movement of up to 20 heavy trucks through the neighborhood. With such an impact on the horizon, the battle is no longer only in the street, but in the courts. As reported Herald of Leonthe project is deeply judicialized. Neighbors and environmentalists are waiting for the Court to resolve a contentious-administrative appeal filed against the municipal licenses granted for the pipeline network. The opacity of the process has fanned the flame of suspicion. The neighborhood spokesperson denounced in the Plaza de San Marcelo that the works began “without the relevant licenses,” calling the operation a “business of two.” The indignation and distrust reach such a point that the neighbors have come to predict that in the future this case will “blow through the air” just as the well-known ‘Wind Plot’ did, demonstrating that everything responds to “the interests of certain people and not to a common good. León’s countdown. While the judges deliberate and the mobilizations do not stop, the clock is ticking. An unappealable countdown has begun: there is a legal limit of five years for the infrastructure to take shape or, on the contrary, the project to decline definitively. The city of León thus appears at a historical crossroads. On one side of the balance, the institutional dream of establishing itself as a pioneering city in Europe in energy transition and thermal independence. On the other, the terror of thousands of families who see an industrial monster installed at the door of their homes. In the coming years the outcome will be decided; Meanwhile, the southern neighborhoods will continue taking to the streets, looking askance at the sky and hoping that justice will act before the wind changes.

Bringing wind energy 100 km from the coast seemed impossible. Until China has thrown away its new metallic “heart”

by

A 25,000-tonne mass of steel, with the surface area of ​​a football field and the height of a 15-story building, is currently crossing the ocean aboard an immense semi-submersible ship. The latest great milestone in Asian engineering is already underway. This colossus has just set sail from the port of Nantong, in the eastern province of Jiangsu, on a 1,090 nautical mile journey to southern China. The protagonist of this monumental journey is called “Hai Feng Zhi Xin“, which translated into Spanish means “heart of the sea wind.” As highlighted in an official statement collected by the agency PR Newswireit is the largest offshore converter station in the world, built by the state-owned Shanghai Zhenhua Heavy Industries Co., Ltd. (ZPMC). Its destination is the waters off the city of Yangjiang, where it will connect to the mammoth Qingzhou V and Qingzhou VII offshore wind farms, operated by the corporation Three Gorges. The “bottleneck” of offshore wind. To understand the magnitude of this project, you have to understand the historical problem that the wind sector faced. As the news agency explains XinhuaUntil now, the development of offshore wind energy has hit a physical wall. Conventional wind turbines produce electricity in alternating current (AC). The problem is that transmitting this alternating current through submarine cables over long distances causes severe and unaffordable energy losses. This technical limitation forced engineers to build wind farms in relatively shallow waters and very close to the coast. However, the wind resource is much stronger, stable and constant the further you go into the open sea. That’s where the technological solution of this new project comes into play as it acts as the largest power adapter on the planet. It collects the energy generated by no less than 163 wind turbines, increases its voltage and converts that alternating current into direct current (DC). So why is this a game changer? Because direct current can travel hundreds of kilometers underwater with minimal energy loss. The platform boasts a record unit capacity of 2,000 megawatts (MW) and operates with a flexible ±500 kilovolts (kV) direct current transmission system. In addition, it is a pioneer in the use of ±525 kV submarine cables for these distances. This technical conversion unlocks access to high-quality wind resources located more than 100 kilometers offshore, making ultra-deepwater wind finally commercially viable. When at full capacity, this metal “heart” will pump out 6 billion kWh of clean electricity a year, a vital boost to the decarbonization efforts of the industrialized Guangdong region. A 25,000 ton giant. Building a power plant in the middle of the raging deep ocean is not a viable option. The project was approached as a gigantic set of modular parts. Assembly, integration of all equipment and installation progressed in parallel onshore (Nantong), demanding an unprecedented level of supply chain coordination. Yan Bing, Senior Specialist of ZPMC cited by PR Newswireexplains that they adopted an integrated construction model of “land assembly, transportation as a single unit, and float-over installation.” This offshore installation method is overwhelmingly complex, requiring millimeter-level adjustment precision amidst strong ocean currents to fit the superstructure. Once locked into place, the platform’s working environment will be unforgiving. As detailed Xinhuawill operate completely autonomously, without a permanent human crew, controlled through intelligent maintenance and remote monitoring systems. Inside, a dense network of electrical, ventilation and fire control systems has been specially armored to resist the very high salinity and corrosive humidity of the deep ocean. The urgency of this megaproject. This feat is within China’s 15th Five-Year Plan (2026-2030). The Asian country has set the goal of reaching 100 gigawatts (GW) of installed offshore wind energy capacity by 2030. China’s problem is that its nearshore wind resources are quickly becoming saturated. Just in February this year, the country connected the first 20-megawatt offshore wind turbine to the grid in Fujian province (made entirely from domestic components), followed by the installation of the world’s largest floating wind platform in Yangjiang. The 100 kilometers from the coast are no longer an unbreakable border. With the imminent ignition of its new energy node, China not only alleviates the energy hunger of its coastal areas, but also establishes a replicable technical model that demonstrates to the entire world that the future of clean energy inevitably requires losing sight of the shore.

In Euskadi they believe they have the solution to the neighbors’ opposition to wind power. Let them take 7% of your profits

by

On May 18, the pre-booking period opened. In less than 24 hours, 51 residents of Rioja Alavesa had already put their money in the wind farm that no one wanted to have next door. Seven percent guaranteed annual profitability. Minimum investment, 1,000 euros. Project name: Gure Haizea. Our wind. Euskadi has not inaugurated a wind farm for twenty years. The last one came into operation in 2006. For two decades, projects have multiplied on paper and have gotten stuck in the courts, in the allegations commissions and in neighborhood assemblies. The result is that the autonomous community, which has a world-class wind industry, produces only 7.9% of its electricity with its own renewable sources. The Basque Government’s objective is to reach 15% in 2030. To achieve this, it needs the residents of the affected municipalities to say yes. And so far, the majority have said no. The park that no one wanted to have next to. The Labraza wind farm, in the Alava municipality of Oion, is under construction. Forty megawatts of power and an investment of 59 million euros. When it comes into operation, it will produce around 99,679 megawatt hours per year, enough to supply around 30,000 homes, and will avoid the emission of approximately 16,300 tons of CO₂. It will also increase the installed wind capacity throughout the Basque Country by 26%, according to data from Iberdrola and of Basque Energy Entity (EVE)the public agency of the Basque Government that co-manages the project through its joint venture with Iberdrola, called Aixeindar. What makes Labraza more than just another wind farm is what this joint venture has just announced: for the first time in Euskadi, citizens will be able to participate in the financing of the project and collect interest for it. The chosen formula is crowdlendinga type of crowdfunding in which individuals lend money to a project and receive a guaranteed annual interest in return. In this case, 7%. The platform that will manage the process is Fundeen, the first Spanish investment platform in renewable energies authorized by the National Securities Market Commission (CNMV). The maximum term is three years. The minimum contribution, 1,000 euros; the maximum, 100,000. The total objective of citizen financing: three million euros. As reported by the Basque Energy Entitythe pre-booking period opened on May 18. In just 24 hours, 51 small investors had already covered 60% of the objective, according to data published by ElDiario.es. The final financing will be formalized in June. The problem that profitability tries to solve. The rejection of wind farms in Spain—and in Euskadi in particular—does not arise out of nowhere. It has concrete and legitimate roots. The reasons for rejection They are diverse: the landscape impact of wind turbines in mountainous areas with strong natural and cultural value, criticism related to noise, the effect on birds and ecosystems, and above all the feeling that large electricity companies obtain benefits while municipalities receive little real compensation. In Álava, more than 100 renewable initiativeswith an especially high concentration that has triggered neighborhood alarms. The underlying issue is more structural. 84% of Spain’s renewable energy is produced in rural areas and in so-called emptied Spain, but without that money stay in the territory. The municipalities assume the visual, sound and landscape impact. Energy travels to cities. The benefits go to the company headquarters. That energy inequality is the core of a problem which has manifested itself in different ways in different territories: Aragon tried to keep its energy surplus, Galicia proposed half-price electricity for residents of municipalities with renewable installations, and now Euskadi is trying 7% profitability for its citizens. The proposal of crowdlending try to attack exactly that gap. If the neighbors also make money from the wind, the equation changes. The park stops being an infrastructure imposed by someone from outside and becomes, at least partially, an own investment. That is why the name in Basque matters: Gure Haizea It’s not just a brand, it’s an argument. More than money, also cheaper electricity. The mechanism is simple in its conception. Through the platform Fundeeninterested citizens can enter the Labraza project as lenders: they contribute between 1,000 and 100,000 euros for a maximum of three years and receive a guaranteed 7% annual interest regardless of what the park produces. They do not buy shares or become owners, but rather creditors of the project. It’s an important distinction: the risk is lower than in direct investing, but so is the control. The initiative is primarily aimed at the inhabitants of Labraza, Barriobusto, Oion and Rioja Alavesa, although it is also open to the entire historic territory of Álava. The objective, according to EVEis to always prioritize investors from the areas closest to the park. It is not limited to financial performance. The inhabitants of the Administrative Boards of Labraza and Barriobusto They will also be entitled to a special electricity rate once the park comes into operation, and throughout its useful life. The package also includes up to 90 local jobs during construction, an initial income of around 1.2 million euros for the municipal coffers when the works start and about 230,000 euros annually in taxes and fees. To explain the details, Iberdrola and EVE organized in-person information sessions in Labastida, Oion and Laguardia during the month of May. Spain already has precedents. What Euskadi presents as new is not exactly its own invention. The model of crowdlending for wind farms has already been tested in other Spanish communities, always with the same platform—Fundeen—and with a profitability also set at around 7%. In the Canary Islands, the company Ayagaures Medioambiente promoted the Renove II wind farm in Agüimes (Gran Canaria) with exactly this scheme. More than 45 investors, prioritizing the residents of the municipality, contributed 1,080,000 euros, 20% of the total budget of just over five million. The success was such that the company is already working on a second project with the same model. In Navarra, the Montes de Cierzo wind farm of the Norwegian Statkraft also … Read more

Wind turbine blades are a deadly danger to birds. The solution: paint them like poisonous snakes

by

One of the great drivers of the global energy transition are wind turbines. Of course, they have been carrying a silent problem for decades: they kill animals. Wind turbines kill 368,000 birds a year in the United States and Canada alone, according to this study published in PubMed. The data for Europe is more fragmented and varies greatly by country and type of facility: in Germany for example place mortality between 100,000 and 250,000 birds per year and SEO/BirdLife esteem that between 1.2 and 4.6 million birds die per year (data from 2023). Given that the expansion of wind power seems unstoppable, the question is how to minimize these deaths, e.g. with self-adaptive speed blades. A research team from the University of Helsinki and the University of Exeter has just publish a proposal unexpectedly simple but effective (judging by its results): painting the blades with the colors of poisonous animals, appealing to one of the most solid principles of evolutionary biology. Those dangerous snake-painted wind turbines. The research team exposed birds to videos of turbines spinning in four color schemes: standard white, a black blade, red-white stripes, and a red-black-yellow biomimetic pattern that was inspired by coral snakes and dart frogs. The result was clear: the birds systematically avoided the blades with the biomimetic pattern and moved closer to the white ones. The remarkable thing about the discovery is why it works. It was not necessary for the birds to learn in the experiment to associate those colors with danger like Pavlov: They were already learned from home. The key is in aposematism, just the opposite of camouflage: signaling danger with colors, something that has been engraved in the nervous system of birds for millions of years. The team simply transferred that evolutionary signal to a huge steel structure. Why is it important. The United States Renewable Energy Institute calculate that per megawatt installed the turbines kill between two and six birds and between four and seven bats, figures that seem small but are considerable on a global scale: the world’s wind capacity already exceeds 1,000 GW installed, according to the Global Wind Energy Council. Reducing the death of animals is the main reason, a good practice that is even more relevant if the species in question has a small population. If the solution is also something as cheap as changing the paint color, the cost-benefit in terms of conservation is difficult to ignore. Context. Aposematism is a documented evolutionary mechanism for almost two centuries: The idea is that certain toxic or dangerous animals warn of their danger with bright colors. The winning combination to scare you is red-black-yellow, universally recognized as a sign of toxicity among vertebrates. What this study does is apply this principle outside of the natural world by projecting it onto an industrial infrastructure. It is not a pioneer: there is a previous investigation in Norway in which they tried painting a blade black to break the optical illusion of a “still hole” created by the spinning turbines and the results were already promising. This new study goes a step further by actively exploiting the perception of danger. How it works. The birds process color in a radically different way from humans. They have four types of photoreceptors instead of three, which gives them tetrachromatic vision and allows them to detect ultraviolet. In short: they appreciate contrast better than humans, so apostematic signals are extraordinarily striking to them. For the experiment they used touch screens designed specifically for birds, so that they interacted with them by moving closer or further away from the stimuli, thus allowing them to precisely quantify how they behaved in response to each pattern. The biomimetic pattern was the most avoided of all. Yes, but. As the research team acknowledges in the paper, all tests were carried out in the laboratory, with birds in front of screens, not with wind turbines spinning in the open field. Perception distance, approach angle, flight speed or weather conditions are variables that the experiment does not replicate. Taking it to the real world can be a very different story. Furthermore, the study was carried out with a limited number of species. Aposematic responses depend on the evolutionary history of each lineage and whether that group has coevolved with those dangerous species in its territory. Come on, what may be useful for birds native to an area may be useless for migratory raptors or for species affected in specific wind farms.

a 1 GW wind farm floating off the coast of Tokyo

by

The waters off the Izu island chain in the Pacific Ocean could soon be home to a colossus of modern engineering. The Tokyo Metropolitan Government has put an unprecedented plan on the table: to build the largest floating offshore wind farm in the world. The goal of this megaproject is to achieve a generation capacity of at least 1 gigawatt (GW), a colossal figure that is equivalent to the power of a conventional nuclear reactor. An ambition that goes beyond. According to data from the International Energy Agency cited by the magazine NatureJapan is heavily dependent on the import of expensive fossil fuels. Turning on a 1 GW wind farm would cut about $300 million annually from the country’s fuel import bill at a stroke. Furthermore, the international context does not give up. A rigorous analysis of the Institute for Energy Economics and Financial Analysis (IEEFA) explains that the Third Gulf War They have once again exposed energy vulnerability of Japan, strongly tied to liquefied natural gas (LNG). Although the central government has responded by restarting old coal plants and nuclear reactors, the IEEFA warns that this strategy is suffocating national renewable energies. The Izu project would represent a clean alternative capable of offering energy security without being at the mercy of geopolitics. Added to this is an existential factor for the capital: protection against natural disasters. As highlighted Japan Newsthis floating wind farm would function as a vital emergency electricity source if a major earthquake struck directly beneath Tokyo, paralyzing the main islands’ grid. The leap from scale: from Norway to the Pacific. To understand the magnitude of what Japan is attempting, it is necessary to look towards the North Sea. Currently, the world’s largest operational floating wind farm is located in Norway and produces less than 100 megawatts. It is the world reference in this technology, but Tokyo’s vision is literally ten times greater. While the Norwegian project demonstrated that the technology was viable, Japan wants to demonstrate that it can be massive, scaling a niche solution to a national-level infrastructure. The engineering behind the giant. Instead of drilling into the ocean floor—which requires heavy excavation that severely damages the local ecosystem—the design will opt for floating platforms. These turbines will rest on the water surface, secured by a complex system of moorings and anchors to the seabed. The captured energy will travel about 100 miles north to power outlets in Tokyo through a hidden artery: high-voltage underwater transmission cables. But Japan is not the docile European North Sea. Its waters face devastating typhoons, strong earthquakes and dizzying coastal depth. To tame these elements, Nature details that Japanese researchers They are using the Fugaku supercomputer—one of the fastest in the world—to simulate the behavior of the wind and optimize the layout of the park. Additionally, they are developing laser remote measurement LiDAR technology to read offshore weather with surgical precision. The State as an explorer. Curiously, the biggest driver of the project is not a private corporation, but the government itself. Given the fear of companies to assume the very high initial costs, the Tokyo Metropolitan Government has decided to act as an explorer. According to SCMPauthorities have tripled their budget for 2026 and will spend about 9 billion yen (about $56 million) on mapping the topography of the seafloor and studying wind patterns. The idea is to deliver this already processed information to contractors to seduce them and encourage them to participate in the tenders. Shadows and skepticism. Despite institutional enthusiasm, the path to 2035 is riddled with pitfalls and the private sector views the plan with undisguised caution. As the Japanese media recalls, corporate distrust has recent precedents: in 2025, the giant Mitsubishi Corp. abandoned important offshore wind projects in Akita and Chiba, citing the extreme complexity of the seabed, the escalation in material costs and the weakness of the yen. The calendar also raises doubts. Experts consulted by Interesting Engineering They call the 2035 goal “unrealistic”, recalling that these types of offshore megaprojects usually take more than a decade to come together and that, today, the Izu region is classified simply as a “preparation zone”, the earliest bureaucratic stage. The gigawatt trap. But are we talking about 1 real GW? Analysts cited by SCMP They warn that, although the installed capacity is 1 GW (similar to a nuclear reactor), the real performance of wind energy is around 40%, well below the 80-90% constant production offered by atomic energy. Finally, there is a systemic problem in the Japanese electricity grid itself. The IEEFA report denounces that the prioritization of nuclear energy baseload regulation by the central government has created a system so rigid that operators are often forced to disconnect and waste (curtailment) renewable energy produced in peak sun or wind. This waste undermines the profitability of any future park and scares away investors. Between utopia and the avant-garde. Izu’s “floating monster” encapsulates the great dilemma of contemporary Japan. On the one hand, it represents the zenith of the technological ambition of a nation willing to tame typhoons, preserve marine ecology and shield the energy survival of one of the largest megalopolises on the planet in the face of global crises and seismic cataclysms. On the other hand, it faces the cold reality of financial balance sheets, bureaucratic bottlenecks and a private sector scalded by inflation. If Tokyo can untangle this tangle, attract construction giants and fire up the turbines by 2035, the project will not only light up the Japanese capital; will become the definitive beacon for global deepwater wind energy. Otherwise, the Izu colossus runs the risk of remaining stuck forever as an expensive utopia on paper.

Asturias’ odyssey to lead offshore wind

by

It has long been thought that the biggest challenge of wind energy offshore (navy) was on the high seas. However, the real challenge is not taming the wind or waves, but rather manufacturing, storing and moving steel giants on land. For a wind turbine to float in the Cantabrian Sea or the North Sea, it first needs to be born in a “factory port”. In short. Under this premise, the Port Authority of Avilés (APA) has just hit the table in the WindEurope Annual Event 2026the reference summit recently held in Madrid. As reported by local mediathe Asturian delegation has come with a clear objective: to consolidate its port as an undisputed industrial node in the European wind value chain. These are not empty declarations of intent. The directors of the APA, Ramón Muñoz-Calero and Manuel Echeverría, took advantage of the forum to hold strategic meetings with giants in the manufacturing of turbines, towers and cables, such as Taihan Cable, Prysmian and ArcelorMittal, as well as global engineering companies of the caliber of Ramboll, DNV and OHLA SATO. Avilés no longer wants to be just a transit point for goods; Its goal is to become ground zero where wind energy offshore takes shape before setting sail. The war for space. But wanting to be a giant means dealing with giant problems. Manufacturing for offshore wind requires manipulating foundations and “monopiles” that can reach 120 meters in length, 12 in diameter and weigh 2,500 tons. This gigantism generates an immediate logistical crisis: lack of space. Moving and assembling these enormous cylinders requires massive esplanades and ultra-resistant infrastructure. In fact, according to The New Spainnot just any dock serves this purpose; Very specific technical characteristics are needed capable of withstanding brutal demands, both in total weight and weight per support points. To prevent this bottleneck from slowing down its expansion, Avilés is on the offensive to gain square meters. In statements collected by Port NewspaperMuñoz-Calero has been blunt: “We are part of the industrial and innovation ecosystem of Avilés and we not only contribute to greater industrialization, but we are in a position to promote it.” The port solution involves two major strategic moves: the acquisition of the industrial land freed by the former ArcelorMittal Coke Batteries and the development of new expansion areas in El Estrellín. The rebirth of the Iberian “hub”. Within the framework of WindEurope, the president of Puertos del Estado, Gustavo Santana, highlighted the country’s potentialremembering that Spain has 46 ports of general interest, an ideal network for renewable deployment. The Government has imminent aid on the table: 212 million euros from the Port EOL-Mar program of the IDAE to adapt docks and drafts, in addition to a ‘Horizon 2030’ plan that will inject more than 1,000 million euros into sustainability. Avilés’ demonstrated muscle. If Avilés raises his hand to ask for funds and investments, he does so protected by his resume. The bet of the Aviles enclave is not a promise for the future, but a reality forged from steel and tons. According to data provided by local mediathe port’s track record is overwhelming: since January 2012, they have shipped more than 18,000 pieces for thirty onshore and offshore wind farm projects. This growth has been driven, in large part, by the success of local company Windar Renovables. The climax of this activity was experienced in 2022, when the port broke its absolute record by moving 140,000 tons of wind traffic in a single year. The Asian lifeguardWhat is happening in the Asturian docks transcends the local; it’s a question industrial geopolitics. For decades, the West lived under the mirage that the future was only in software, abandoning heavy industry. Now, Europe has taken a “bath of reality”: energy sovereignty depends, ultimately, on knowing how to smelt metal. This revolution covers the entire Asturian coast. A few kilometers from Avilés, in the Gijón port of El Musel, China has seen his opportunity. The landing of the Asian giant Dajin Offshore – which has joined forces with the Asturian group Zima to build a plant – shows that technology and the eastern financial muscle can be the oxygen ball that the Asturian auxiliary industry needs to lead again. Not in vain, the Asian country today builds 74% of the planet’s renewable energy. The industrial clock against the bureaucratic clock. Asturias, which has been trying to digest the mining and steel conversion for three decades, has before it the historic opportunity to abandon its role as a simple “quarry” to become a center of high added value. Offshore wind promises reindustrialization, highly qualified employment and a leading role in the European green economy. However, the success of this transformation will not be measured solely by political intentions or memoranda signed in offices. The real litmus test is in institutional agility and territory management. The international demand is there and cargo ships are already waiting on the coast. Now, the only question is whether the bureaucracy will be fast enough to ensure that, in the docks of Asturias, there is enough space and strength to sustain the full weight of Europe’s energy future.

Europe has just measured how much wind potential Spain has left. The answer is an overwhelming first place

by

If we look at the sky and our plains, the country is an undisputed giant. According to official data from the Wind Business Association (AEE)wind energy is already the first source of electricity generation in our country, covering an impressive 24% of national demand. With more than 31,600 megawatts (MW) of accumulated power distributed in 1,412 wind farms, Spain has consolidated itself as the second country in Europe (only behind Germany) and the sixth in the world in installed power. However, behind this success of “emptied Spain” a broken bridge hides. The wind blows and the blades turn, but we lack the cables to bring that clean energy to the cities and factories where it is actually consumed. And right now, when bureaucracy threatens to suffocate the sector, Europe has just put on the table a report that shows that what we have built to date is just the tip of the iceberg: the margin for growth that Spain has left is not only large, it is overwhelmingly higher than that of the rest of the continent. An overwhelming first place. The confirmation has come directly from Brussels. The Joint Research Center (JRC) of the European Commission has just published the second edition of the report ENPRESSO 2. This scientific document does not make estimates on the fly: it measures the feasible technical potential of onshore wind energy in Europe with a very high geographical resolution of 1 square kilometer. The results position Spain as the leader of the entire EU by a very wide margin. As the expert Joaquín Coronado explains:the figures are stratospheric. In the reference scenario, Spain reaches a technical potential of 183.9 gigawatts (GW) of installable capacity and 415.4 TWh/year of generation. More than double that of Romania and Sweden, the next in the ranking. If we cross this with our current capacity, the conclusion is stunning: the ceiling is very far away. How do we lead with such advantage? The merit of this first place is even greater if we understand how it has been calculated. The European Commission report has applied very strict filters For an area to be considered suitable: the mills cannot be more than 5 kilometers from a road, nor more than 3 kilometers from the electrical grid, and must respect minimum distances from population centers (1 km) and protected areas such as Natura 2000. After passing all these demanding filters, 5.8% of the Spanish territory is available and suitable to house wind turbines. As Coronado explainsour low relative population density in those areas where it is windier gives us a brutal competitive advantage. We are much less sensitive to changes in separation distances (so-called “setbacks”) than densely populated countries such as Germany, France or Poland. Even if Europe forced us to move 2 kilometers away from towns (the most restrictive scenario), Spain would still retain 52.8 GW of potential. It’s not all lights. The energy expert warns of a purely internal problem: “regulatory heterogeneity.” While national regulations establish a separation distance of 500 meters for populations, there are autonomous communities such as the Balearic Islands, Navarra or Valencia that require 1,000 meters, and others such as the Basque Country or the Canary Islands that request 400. This regulatory fragmentation means that the real potential varies drastically depending on which side of the autonomous border the wind blows. The bureaucratic infarction of a “full” network. At this point in the x-ray, it is time to address the elephant in the room. As we have explained in Xatakathe Spanish electrical system suffers a serious administrative “thrombosis”. The network is not physically collapsed, but administratively “full” and underused. Panic broke out when the National Markets and Competition Commission (CNMC) was forced to delay the capacity maps until May because 90% of the nodes appeared in red. Faced with this bottleneckthe CEO of Red Eléctrica, Roberto García Merino, defends himself by remembering that they have 1.5 billion ready to invest, but the paperwork delays works that barely require a year of physical work for up to a decade. As if the internal traffic jam were not enough, we come across France’s external plug, whose pyrrhic interconnection (2.8%) isolates us and forces us to throw away cheap energy to protect its nuclear industry. The risk of dying of success. Spain finds itself at a historical crossroads. We have the climate, the soil, the wind and the endorsement of the EU. If we add to this wind potential the 19 GW of reversible hydraulics already in the pipeline, Spain has in its power to develop the most competitive emissions-free electricity mix in all of Europe. But to achieve that future, heat maps and reports from Brussels are not enough. It is necessary, as experts point out, to homogenize legislation between communities, compensate local populations and, above all, urgently expedite permits to build the network. As a summary from the sector: “The plans are very nice, but they have to be built.” Image | Carlos Teixidor Cadenas Xataka | Macron believes that Spain has “a problem” with renewables. What it really means is that they are “competition”

China has broken records by expanding its wind and solar capacity. Now going all out with pumped hydroelectric storage

by

In December 2020, Xi Jinping, the president of China, announced that the country he leads would reach 1,200 GW of installed wind and solar capacity by 2030. He was wrong. China reached this figure in July 2024and, therefore, no less than six years before the deadline set by the Government. At the end of 2025, the accumulated capacity of these two energy sources exceeded 1,840 GW, making them those responsible for 47.3% of China’s electrical capacity. That was the first time wind and solar energy They surpassed coal and gas in the Chinese electricity mix. However, the rapid expansion of these renewable energy sources has placed China in a scenario in which it is crucial to find a way to integrate them efficiently into the country’s energy system. Wind and solar energy have an intermittent nature, so it is essential to develop large-scale storage infrastructure and a network that is capable of managing the peaks and valleys of supply in an automated way. Pumping is the most efficient way to store energy on a large scale To solve this challenge, China has launched a strategy that proposes transforming energy storage into a national priority. One of the solutions it is deploying is installing large battery systems at a record pace. In 2025 its battery storage capacity grew by 75% compared to 2024. However, in this area its biggest bet is pumped hydroelectric storage. At the moment China has more pumping projects underway than all the other countries in the world combined. Their plan is to use excess solar and wind energy to pump water into elevated reservoirs and release it when electricity is needed. Pumped hydroelectric plants fit very well in mountainous countries because they allow you to take advantage of uneven terrain to move large masses of water between two reservoirs or deposits at different heights. China currently has more pumping projects underway than all other countries in the world combined. The excess energy can be used to pump water from the lower reservoir to the upper one using a hydraulic pump, and to recover that energy it is only necessary to let it fall back into the lower reservoir from the upper one so that it drives a hydraulic turbine. Pumped hydroelectricity has been used for more than a century, but it remains a very attractive technology. In fact, it is currently one of the energy storage systems more efficient large scale. The largest facility of its kind in Europe it is the pumped hydroelectric plant of the Cortes–La Muela complex (La Muela I + La Muela II), on the Júcar river (Valencia). If we stick to pumped hydro storage, China aims to add about 100 GW in five years compared to the current 59 GW. If it achieves its purpose, this technology will become the basis of its long-term storage system in this country. Still, the Government has also committed to more rapidly expanding battery storage. At the end of 2025 the accumulated capacity reached 136 GWwhich multiplies by 40 the level proposed by the previous five-year plan. Lithium-ion batteries clearly dominate this market, but China is investigating alternative technologiessuch as sodium-ion batteries, compressed air batteries, flywheels or gravitational storage.
