Interesting stats on EVs and energy use in the US, developments in wind and tidal power, a plastic recycling microfactory, and an "unprecedented collapse" in EU fossil fuel generation.

Swiss researchers say they have developed a concentrated solar reactor that produces green hydrogen at a rate of more than 2 kilowatts while maintaining efficiencies above 20%. Apparently that equals 0.5 kg of hydrogen per day, which this Physics World article says is "unprecedented."
But is it promising? Can it be scaled? 🤔 I'm curious to see if/how this technology develops… if we COULD create a cost-effective and scalable way to use solar power to produce green hydrogen, that would probably be a good thing – especially given recent advances in hydrogen-powered planes.
