Massachusetts Institute of Technology (MIT) researchers have developed a solar desalinator with high water output, via a multi-stage system of evaporators and condensers. It offers cost-effective solar desalination, making solar-produced drinking water cheaper than tap water for the first time.

As the Oxford Institute for Energy Studies underlines the delays in hydrogen storage investments, a group of researchers have developed a cost-effective material to absorb hydrogen at non-cryogenic temperatures, which they consider optimal for fuel cell storage systems.

Germany advanced its hydrogen ambitions this week with a fresh call for the International Green Hydrogen Promotion Program in Latin America, a collaborative deal with the UK government, and a tie-up between DHL and Sasol for sustainable aviation fuels based on green hydrogen (eSAF).

The International Energy Agency has warned that lagging policy support, rising costs, and supply chain disruptions threaten the profitability of low-emission hydrogen, while the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has identified hydrogen seeps in South Australia.

Hydrogen is nothing new, but it could become a decarbonized energy vector to transform renewable electrons into renewable fuels, displacing fossil fuels in multiple applications. Laurence Boisramé, global director of hydrogen at Bureau Veritas, recently spoke with pv magazine about improving hydrogen market transparency, but she noted that “global consensus will take time – at least a few years.”

Hitachi Energy has delivered a modular solution to electrify a 20 MW electrolyzer to produce hydrogen to heat steel before rolling, while Enapter has unveiled its AEM electrolyzers for industrial and refuelling pilot projects.

Mexican researchers have revealed test results for offshore wind-based hydrogen production, while Turkey has started negotiating hydrogen facility partnerships with the United Arab Emirates.

Agora Energiewende says Europe needs €30 billion ($32.2 billion) by 2027 to rebuild its PV industry. It calls for up to €30 billion until 2027 and up to €94.5 billion from 2028 to 2034 to revive the European solar sector.

H2FLY claims that a recent three-hour test flight, entirely powered by liquid hydrogen, could lead to sustainable long-range flights fueled by liquefied, cryogenic hydrogen. Solaris, meanwhile, has started selling hydrogen buses in Italy.

BloombergNEF Senior Analyst Jenny Chase and Aurora Energy Research Renewables Lead Rebecca McManus speak with pv magazine about financial market trends for solar companies and the role of overcapacity as a driver of turbulence in the industry.
