Scientists have simulated a solar-powered hydrogen production system consisting of 32,050 photovoltaic panels, a pumping system, a seawater reverse osmosis desalination unit, an electrolyzer and a hydrogen storage tank. Operating the system in Oman could potentially generate a levelized electricity cost of $0.05/kWh and a levelized hydrogen cost of $9.5/kg. December 23, 2025 Lior Kahana A research team from the University of Exeter in the UK has simulated an off-grid green hydrogen production system, powered by floating photovoltaic (FPV) technology and seawater reverse osmosis desalination (SWRO), designed to support green mobility in Oman. The system was believed to operate in…

Preliminary data from the Sustainable Energy Authority of Ireland (SEAI) for 2025 shows that monthly utility-scale solar energy generation increased from an average of 0.73 TWh in 2024 to 0.99 TWh in the first nine months of 2025. December 22, 2025 Blathnaid O’Dea Ireland’s €18.9 billion ($22.2 billion) investment package for 2026-2030 has been published by the Commission for the Regulation of Utilities (CRU) and the government. The plan – called Price Review 6 (PR6) – will continue to work with industry and developers to increase the supply of onshore wind and solar energy by 2030. According to the Sustainable…

Market pressures in the solar and storage sectors often favor low-cost solutions, but long-term success depends on balancing price, quality and reliability for assets designed to last for decades. Numerous examples, from low-quality silicon modules to hydrogen and redox power storage in homes, show how technically ambitious products can fail if cost, complexity or sustainability are misjudged. December 22, 2025 MARTIN SCHACHINGER, PVXCHANGE.com It is a well-known reality in the market: the best product does not always win. Often the cheapest option wins. No matter how advanced a development or how well thought out the concept, a product has little…

Researchers in China have investigated the long-term stability of horizontally connected salt caverns used for compressed air energy storage. They found that about 85% of existing salt caverns in their home country are suitable for this configuration. December 22, 2025 Lior Kahana A research group from China has investigated the long-term stability of using two-butted-well horizontal (TWH) located in low-grade, submerging salt layers for compressed air energy storage (CAES). “According to statistical data, about 85% of existing salt caverns in China are composed of TWH,” the research team explains. “As salt cavern energy storage reservoirs expand, high-quality caverns with favorable…
