The Hydrogen Stream: EU endorses 100 cross-border hydrogen projects
The selected projects will be eligible for EU funding from the Connecting Europe Facility and will benefit from streamlined approval and regulatory processes.
Cooling PV modules with seawater
A research team in India developed a passive solar-panel cooling method using a thin, still layer of seawater placed over the module surface. Tests showed that while a thick water layer sharply reduced energy output, a thin 5 mm layer lowered module temperatures and increased daily energy generation by up to 8.86%.
ABB finalizes acquisition of Gamesa Electric
The Swiss group acquired Gamesa Electric’s power electronics business in Spain from Siemens Gamesa. The financial terms of the deal were not revealed.
Spain awards 133 energy-storage projects totaling 2.4 GW and 10 GWh
Spain’s Institute for the Diversification and Saving of Energy confirmed €827 million ($961.4 million) in European Regional Development Fund co-financing for 133 energy-storage projects with a combined capacity of about 2.4 GW and 10 GWh.
Spain’s Sumcab launches new cables for PV installations
Spanish manufacturer Sumcab says its new ToughGround and Overground cables are designed for underground and overhead photovoltaic systems throughout the world, offering durability, rapid installation, and a 30-year lifespan.
Spanish researchers developing rear-side concentrated PV modules for agrivoltaics
Researchers at University of Jaén in Spain have demonstrated a semi-transparent crystalline silicon solar photovoltaic module with rear-side optical concentrators for agrivoltaics applications.
Naturgy, BlueNewables build 1 MW offshore solar plant in Spain
Naturgy and BlueNewables are developing a 1 MW floating solar installation off Spain’s Mediterranean coast, with two 500 kW units designed for open-sea operation and scheduled to begin testing in 2026.
Key takeaways from Spain’s Genera tradeshow
Spain’s Genera 2025 trade fair highlighted advances in solar, storage and grid-forming technologies, along with industry calls for clearer regulation, stronger market design and faster permitting to support future deployment.
Nanostructured antireflective coating for gallium arsenide solar cells
A Spanish research team demonstrated a broadband antireflective coating for gallium arsenide solar cells. Based on thermally oxidized gallium nanoparticles, the nanostructured coating reduced reflectance by 30% across the solar spectrum, and increased solar cell performance by 10%.
The Hydrogen Stream: European Commission launches H2 tender
The European Commission has launched its first Hydrogen Mechanism call to link suppliers with buyers, while Italian researchers say PV, wind, storage, and electrolyzers can slash island transport emissions by 90% and cut costs nearly one-third.
