port

Every time a megaship arrives at a port, the electrical grid collapses. The alternative already exists and does not need cables to the city

by

Ports around the world face an urgent and unavoidable mandate: decarbonize. The requirement is to turn off the huge diesel engines of commercial and cruise ships once they dock, connecting them to the local electrical grid. However, in practice, port cities have hit a concrete wall: there is not enough capacity in the land network to plug in these giants of the sea. Faced with this bottleneck, the engineering response has been to take the problem off the ground. A consortium backed by the United Kingdom and led by the firm ELIRE Maritime has been successfully validated what they define as “the world’s first floating, grid-independent hydrogen energy center.” The end of endless port works? To understand the impact of this development, you have to look at the current logistical ordeal. As emphasized Enlitinstall traditional shore power supply systems (known in the industry as shore power) is a real nightmare. The process can take between three and seven years, as it requires massive reinforcements of the network, improvements in substations, complex civil works and permitting deadlines that paralyze any progress. All this consuming land space that most ports lack. By placing the energy infrastructure directly in the water, this obstacle is overcome in one fell swoop. Furthermore, since ELIRE Maritime highlight a crucial financial advantage– The system avoids the risk of creating “stranded assets”. Unlike a concrete substation that cannot be moved if shipping routes change, this floating mega plant can be relocated as market demand dictates, giving port authorities complete independence from the network. Technological radiography. Far from being a mere concept on paper, the technology has just passed a rigorous six-month validation program. The physical design, echoed by all the media, consists of three interconnected hexagonal floating platforms that occupy about 1,200 square meters. But how does it supply power without collapsing? The system does not use huge generators to inject shock energy into the ship, but rather works on the premise of a “giant floating battery.” Through continuously operating 1.3 MW modular fuel cells (supported by up to 146 kW of onboard solar panels), the system slowly charges a massive 45 MWh battery bank throughout the week. When a ship docks, this battery releases energy quickly, delivering 5 MW of clean, continuous power without flinching. To fuel this process, the system consumes between 7,500 and 8,000 kilos of hydrogen per week. It has seven tanks on board integrated into low-pressure containers, which require refueling a couple of times a week. This allows ports to gradually adopt hydrogen without having to undertake extensive work to build pipelines or permanent storage facilities on land. The real impact. To ensure its real-world viability, the platform has undergone stability and wave testing in tanks at the University of Strathclyde, while industry giants such as Schneider Electric and Ricardo UK have successfully validated its entire complex electrical architecture. The environmental lights: According to the feasibility analyzes of the Ricardo consulting firm, the system can reduce emissions from docked ships by 77% compared to traditional diesel generation. In tangible figures, this represents a saving of about 47 tons of CO₂ per ship each week (almost 2,450 tons annually), in addition to completely eradicating emissions of toxic particles, nitrogen oxides (NOx) and sulfur (SOx) that poison the air in coastal cities. The shadow of cost: Today, this solution is more expensive than plugging into the conventional network. The estimated energy cost of this hydrogen hub is between £0.25 and £0.50 per kWh, compared to £0.15 – £0.25 for the traditional ground system. However, the consortium argues that this initial extra cost is offset by the astonishing speed of deployment and they anticipate that standardization and the future drop in the price of hydrogen will equalize the trade balance. The potential is immense. The consortium estimates a global market of 62 TWh annually for grid-independent maritime solutions, with the potential to avoid the emission of 500,000 tons of CO₂ in the next decade. Next stops. As detailed ELIRE Maritimethe consortium is already in commercial talks to start the first real deployments in first-tier ports such as London, Singapore, Hamburg, Brisbane and Riga. The future of maritime decarbonization seems to have found a shortcut. It is not about inventing exotic technologies from scratch, but about integrating what we already know works (hydrogen, batteries and electrical power systems) in a much smarter way. If the mainland does not have enough electricity to power the giants of the oceans, the solution, ironically, has always been to go back into the sea.

The best uses for the port beyond loading your mobile

Let’s tell you everything What you can do with the USB-C connector of your Android mobile. This is the slot that is used to put the mobile to load, although there are also many other things that you will be able to do with it, and that is what we are going to tell you. We are going to tell you at different points everything you will be able to do with this connector. We will explain it to you in a very summarized way, so that you understand that characteristic, and thus be able to think what you can do Better data transfer To be able to send data from another device to your mobile online, messages to oneself in messaging apps, or through the cloud or bluetooth is fine. But wired connection is still faster When moving the data from or to your Android. Although the transmission speed may depend on the USB-C version that integrates each manufacturer, and when you connect two devices with each other the speed is the maximum of the slowest of the two, it will almost always be faster than transfer data wirelessly. Entertainment that does not occupy memory As this is a standardized connector and almost everyone uses it, you will also be able to connect external storage units that also use USB-C. For example, there are some pendrive and hard drives that use it, and there are also SD or microSD card adapters. This will allow you to carry large files in these units, and connect them to the mobile to consume them. Think, for example, in entertainment, such as Books, music or videos. You can take them in these units without spending internal storage or cloud space. Manual backups Beyond the backups made in the cloud, you can Save important files manually In these storage units that we have mentioned before. Because there may be some that you want to keep in another physical place, and this is a good method. For example, imagine that you have stored photos or videos that occupy a lot, but you do not want to lose or pay more space in the cloud. Well, you can keep them manually in these units to keep them but save the space they occupy. Load other devices Another thing you will be able to do is Use your Android as an external batterysomething especially useful in the event that you have a model with a especially large battery. You can connect another device to it, and load that other mobile or tablet. Of course, don’t forget that this will make your battery run faster. Use controls to play without latency If you usually use your mobile or Android tablet to play top -level games, it is possible that in some cases you prefer to use a command. It may not matter in some games, but there are others in which It may be important to use a wiring control Use a USB-C connector. As in data transfers, when you use a wiring control You will have much less latencywhich means that since you press a button until the order of the button reaches the mobile will pass less milliseconds. In some competitive games this can prevent great disadvantages. Connect a mouse or keyboard to your Android If you have an adapter to be able to connect the USB of type a that mice use at the USB-C port of your Android, you will be able to connect a mouse to use it On your mobile or tablet. Maybe in contexts such as when you have connected a monitor, you can serve to move a little better by the interface. In addition to a mouse, you can also connect a keyboard, just like what we have told you before connecting a control control. Use your mobile as a camera … or vice versa You can use your camera Android as webcam in Windowsand thus take advantage of the quality of which your phone equips so you don’t need to buy any external. For this you will need a cable that connects the mobile to the computer, and A specific application Help you take advantage of it. You can also connect an external or webcam camera to your Android using an OTG adapter (ON-THE-GO). This is much less common, and does not always work well, since it depends on the capabilities of each phone, and the applications you have installed to take advantage of this.

The secrets of the port of Shanghai, the colossus of international trade where automation reigns

by

Check out around you. The screen you are looking at, the clothes you wear or even your coffee maker have probably crossed the ocean in a container before reaching you. It is not a simple random assumption. About 80% of the goods travel by boat, which makes maritime transport into the backbone of the World Trade. Without this machinery running precisely, getting many of the things we use every day would be little less than an odyssey. A key piece of this system is the sea ports. We are talking about the nerve centers that not only receive and dispatch millions of containers a year, but also coordinate a millimeter logistics that allows goods to circulate fluently between continents. It is no secret that this world is in constant movement, but there is a title that has not changed hands for a long time: the port of Shanghai has been the most active in the world for 14 years. The port of Shanghai is also a port megaciudad After a long time, In 2024 the port of Shanghai became In the first in the world to handle more than 50 million teu in a single year. And when we talk about TEU, we refer to the standard container unit of 20 feet (6.1 meters) long. This port did not begin its rise to the throne yesterday. One of his first great achievements occurred in 1994, when he first exceeded the million TEU. Since then, its performance has grown exponentially, multiplying by 50 in three decades. There is no doubt that this reality is directly related to China’s industrial muscle, which has established itself as The greatest manufacturing power in the worldand with the spirit of the Asian giant for developing ambitious works. The port of Shanghai has not stopped evolving during the last decades. Automated terminals have gained ground to improve efficiency and security drastically. Less people work and everything becomes much faster. The port has completely automated terminals where tasks such as goods discharge, stacking and output are controlled by the “brain” of the management system. Sun Jinyu, one of the leaders of the Shangdong terminal, had in 2021 that The cranes needed about 108 operators in the past, but automation had allowed the same tasks With only 7 operators. And, because of that was not enough, most of the work was done through remote operation. But an impressive infrastructure would not be enough without strategic ties. The port of Shanghai began to handle containers in the 1970s and it was not until 1978 that he opened his first international route, one that joined China with Australia. At present, it is linked to almost 350 international routes, connecting more than 700 ports in more than 200 countries and regions of the world. Internal level, it also has 22 ports distributed by various Chinese provinces, consolidating its role as a key node in global trade.
