Batteries just keep on getting cheaper and cheaper.

The average price of lithium-ion battery cells dropped from $290 per kilowatt-hour in 2014 to $103 in 2023.

If you live near enough to a river and have 15 minutes spare to sit quietly next to the river, can I encourage you to take part in the Big River Watch.

250 MW electrolyzer and 200 MW hydrogen gas generator to demonstrate a solution for 100% renewable electricity. Electrolyzer converts excess wind and solar to hydrogen, generator produces dispatchable electricity at times of too little wind and sun. Completion planned for 2026.

"A final agreement is dependent on further studies to be conducted over the next six months."

Type of hydrogen storage foreseen is not clear from the article. Should be underground at this scale.

There's "no public policy case for hydrogen to be used to heat individual buildings".

This is not me saying this it is the UK's National Infrastructure Commission advising the government.

Abandoned coal mines are providing a surprisingly potent source of zero-carbon energy in Europe.

This project in Gateshead is using the warm water that has filled the tunnels to heat hundreds of homes and businesses in the former coalfield community.
