@Extra_Special_Carbon there is more than one type of efficiency. The metric you're hanging your thesis on is irrelevant. Have been writing about it for years on RMP. Tell me why electrolyzer growth is planned to double each year into the 2030's. The US DOE, governments of Germany, China, Japan, and South Korea all see it the way RMP does. #hydrogen will scale to replace fossil fuels. Batteries are great, but smaller packs per vehicle is better for the environment, air, and water. We're done.
