HFC cars generally have batteries, like the Toyota Mirai.

But they’ve already lost to EVs.

Batteries aren’t going anywhere, for cars or houses or just the grid.

Ships already run electricity and there are EV ferries already in operation. Sure there’s work to be done for conversion, but I think it’s pretty understood at this point.

Batteries are sealed. They’re used in port cities and other humid areas. This isn’t an unsolved problem.

It can be used in zeppelins, too.

Great but not relevant to energy storage for the grid of HFC in cars. I wasn’t aware we were talking about flight in this thread.

Many do, yes. None of SpaceX’s do though.

But why is this relevant? 🚀

altenergy.bsky.social @altenergy.bsky.social · 1d

Hydrogen is not a good solution for storage due to inherent inefficiencies as well as serious storage problems. Scotland needs more batteries and more electrical demand to eat up the current “excess” production leading to curtailment. A better grid would help too.

Are we arguing about what they were called, panels or something else? Seems silly.

But here’s a clip from the 1979 NYTimes article calling them panels.

WASHINGTON, June 20 - President
Carter climbed atop the roof of the White House today and, amid a noonday blaze of solar power, dedicated a solar heating system and announced his solar energy Plan.
"No one can ever embargo the sun or interrupt its delivery to us," the President said in a brief ceremony on the roof of the West Wing.
He stood in front of four large panels, called collectors, fitted with rods that circulate sun-heated water through connecting pipes to ,a storage tank, much as a normal heater does. If the collectors do not bring the water up to tap temperatures, a regular heater turns on. The system will be used mostly for the White House staff mess.
