Hydrogen made by splitting water with renewable electricity, used as a low-carbon fuel and feedstock for industries like steel and chemicals.
Ulm University chemists report in Nature Catalysis that the working surface of nickel anodes in alkaline electrolysis is nickel dioxide, not oxyhydroxide. That surface holds no hydrogen, so the team says reaction pathways at the oxygen electrode must be reassessed.
Reality
Imperial College London researchers measuring oxygen live found hematite converts about 80% of charge to oxygen only once surface charge builds. At lower currents much of it feeds competing surface reactions, so current alone overstates the oxygen.
Reality
Chinese Academy of Sciences researchers report a 250 kW seawater hydrogen plant with 14.4% better electricity use than alkaline electrolysis. Stack heat distills the plant's own feed water and leaves a brine that could yield uranium, though no recovery rate has been reported.

Oregon State chemists report a framework, BVR-19, that makes hydrogen from water in light with no added expensive metal catalyst. Without a reported rate or efficiency, its bearing on green hydrogen's roughly $5-a-kilogram price is still untested.

Korea's climate ministry targets commercial tandem solar cells by 2028 in a roadmap that will shape the country's 2028 national R&D investment standards. Superconducting grids go to a new advisory committee that will study the state's role over 10 to 20 years.
Reality
Oregon State researchers report in JACS that BVR-19, a metal-organic framework, makes hydrogen from water under light without an added metal catalyst. The work gives chemists design rules for solar hydrogen, but whether it can make the fuel cheaper depends on production rates and lifetimes.

Alice Di Bella's team at CMCC modelled heavy industry inside Europe's whole energy system, and the cheaper climate-neutral route buys part-processed green iron abroad and finishes the product in Europe.

A Singapore team's solar cell ran for more than 72 hours on seawater and pulled hydrazine down to 0.5 parts per billion. The buyer for a unit like that is a site already paying to destroy the stuff.

Stegra's plant at Boden will reduce iron with green hydrogen instead of coal. Google's share of the first year of output arrives as environmental attribute certificates a buyer can count against construction emissions.
Reality
Hyundai's 9 trillion won of committed capital at Saemangeum has a groundbreaking date, a GPU count and a robot output target. Who buys the robots is still being worked out between the agency and the trade ministry.

Korean researchers ordered platinum and nickel into a fixed lattice and ran it for four months. The result is a replacement-cost input, but the operating point behind it is missing.
