The state that built the world's first grid-level "big battery" is striking out on an even more ambitious green energy project: the world's biggest hydrogen power station, fed by an electrolysis facility 10 times larger than anything running today.

There are already "smart" windows that can be electronically switched between either letting sunlight through or blocking it. A new multi-layered one, however, can be set to several energy-saving light filtration modes.

Green hydrogen is going to demand a lot of water for electrolysis – nine liters of pure water for every kilogram of hydrogen. Researchers say they've found a simple way to use seawater in standard electrolyzers, and that's big news for clean energy.

Once a mine has been exhausted of its ore, there's really no use for it anymore – it just becomes an abandoned hole in the ground. According to a new study, however, the shafts of such mines could serve in energy-storing gravity batteries.

Russia is the only country that sells the HALEU fuel that some next-generation nuclear plants will rely on, and with sanctions now in place due to the war in Ukraine, TerraPower has now conceded its demo timeline will blow out by at least two years.

Chinese researchers say they've demonstrated a seawater electrolyzer that works as efficiently as a commercial freshwater electrolyzer for months on end without corroding itself to death. It also looks like these machines could harvest lithium, too.
