minus-squareJohnDClay@sh.itjust.workslinkfedilinkEnglisharrow-up1·1 year agoMaybe I’m missing other conversion factors, but hydrogen has a volumetric energy density of 9MJ/L which is about 2.5kWh/L compared to about 1.7kWh/L for the newest Tesla batteries. So hydrogen is more energy dense than batteries even by volume.
minus-squarePipoca@lemmy.worldlinkfedilinkEnglisharrow-up1·1 year agoAren’t those the numbers for liquid hydrogen?
minus-squareJohnDClay@sh.itjust.workslinkfedilinkEnglisharrow-up1·1 year agoOh maybe. That would make extra complications. Looks like low pressure gas is 0.5 kWh/L which is more in line with what you were saying.
