Europe is looking for a place to light its “artificial sun” and Spain only has to defeat Italy and Germany to achieve it
For decades, nuclear fusion has been the distant horizon of energy: an almost mythical promise, always thirty years ahead. A future without a map. In full electrification of the economy and with demand pushed by the digital industry and data centers, Europe has begun to set coordinates for that promise: where to build the first commercial centers. For the first time, the “artificial sun” is no longer just a scientific experiment and it becomes a problem of territory, infrastructure and industrial planning. And in this new European energy map, Spain appears among the best positioned countries. A new path. Gauss Fusion, the European company created to power the first generation of commercial fusion plants on the continent, has completed the first comprehensive European study of potential sites for this technology, in collaboration with the Technical University of Munich (TUM). The study culminates in a map that did not exist until now. A map that indicates 150 industrial clusters and up to 900 potential sites spread across nine European countries. Behind each point there is an analysis of geology, seismicity, meteorology, refrigeration, access to the electrical grid and existing infrastructure, aligned with standards of the International Atomic Energy Agency (IAEA). Spain on the horizon. It appears as the third country with the most identified clusters: 17, only behind Germany (53) and Italy (22), and ahead of France, Austria, the Netherlands or Switzerland. This is not a political decision or a formal candidacy, but rather a strictly technical diagnosis: where it would be possible to build a first-generation fusion power plant if it had to be done tomorrow. “That Spain appears as the third country with the most potential clusters is due solely to technical criteria,” emphasizes Milena Roveda, CEO of Gauss Fusion, in an interview with Xataka. “The study follows an objective methodology consistent with international standards. There are no strategic weightings or quotas per country,” he emphasizes. And that nuance is key. The map does not look for winners or distribute investments: it identifies where the minimum physical and industrial conditions already exist to host a fusion power plant. But why Spain? On the one hand, its fusion ecosystem. Spain is one of the European countries with greater historical involvement in ITERhouses the headquarters of Fusion for Energy in Barcelona and has achieved key industrial contracts for national companies. Added to this is the role of CIEMATuniversities with leading groups in plasma physics and materials, and the beginning of the construction of IFMIF-DONES in Granadaa critical infrastructure to validate materials for future reactors. On the other hand, their regulatory experience. “Spain has a nuclear regulatory body with extensive prestige and experience,” highlights Roveda. From an industrial point of view, Roveda insists that Spain should not limit itself to being a host: “It has the potential to be a key piece in the merger value chain. Companies like IDOM already have demonstrated that can design and deliver extremely complex systems. Where could these clusters be? The map does not draw isolated points, but rather broad areas. The study identifies regional clusters capable of containing multiple viable locations. In Spain, they appear spread over a good part of the territory – from Andalusia and Extremadura to Castilla y León, Aragon, Catalonia, Galicia, the Basque Country and the Valencian Community – and are concentrated in industrial areas with high electrical demandgood network connectivity and, in some cases, close to old energy enclaves that could reuse part of their infrastructure. Frédérick Bordry, CTO of Gauss Fusion, explains to Xataka that the objective of the map is not to select a specific place, but “to have a broad database that allows collaboration with authorities, companies and other interested parties.” The final decision, remember, will not come until the end of 2027. What would a commercial fusion center be like? Talking about commercial fusion is no longer talking about experiments like ITER. Gauss Fusion works with the concept of a GIGA plantcapable of producing 1 gigawatt of electricity. This implies very specific industrial requirements. “Assuming an efficiency of 30%, a plant of this type must safely evacuate about 2 GW of heat,” explains Bordry. In practice, this requires access to rivers, reservoirs or the sea, as well as robust electrical infrastructure. Unlike fission, fusion does not produce chain reactions, is self-limiting, does not emit CO₂ and does not generate long-lived radioactive waste. “Due to its safety features, it could and should be integrated near urban and industrial centers,” says Bordry, even supplying waste heat for industrial uses or district heating. This aspect connects with a trend that is already seen in Europe: heat recovery in district heating networks, as happens in Finland with data centerseither the use of large industrial heat pumps. The process now enters a delicate phase. According to Gauss Fusion, the goal is to reduce the European map to between two and five final locations by the end of 2026, and make the final decision in 2027. But the technical criteria will not be the only ones. “Political will, the regulatory framework and social acceptance will be essential,” emphasizes Roveda. In his opinion, Europe needs policies that promote fusion as a new industrial engine, and regulations “adapted to the real risk of these facilities.” Social acceptance will also be key. “Transparency and citizen participation are essential,” he says. “We have to explain well what fusion is and what it is not.” A project that covers a lot. For Bordry, no European country can tackle a project of this magnitude alone. The merger will require a continental industrial alliance, something that Roveda defines as a “fusion Eurofighter”, in which Spain should play a central role, not only as a location, but as a technological and industrial supplier. In a context in which European electricity demand could grow up to 75% by 2050fusion is beginning to be seen not as a distant promise, but as one more piece of the energy puzzle, complementary to renewables, storage and electrification. An open closure, but with a … Read more
