Hydrogen is a gas too and you can make it without emitting carbon. If you want you can also make methane from atmospheric carbon and water.

FWIW, the latest analysis I've seen seems to suggest that biomethane is probably the way to go for last-resort long term backup. Hydrogen is just too fickle.

Thank goodness that around 99% of our current hydrogen is made from fossil fuels!

If your going to burn the power turning it into hydrogen then you save a shitload of that power by putting it in batteries instead.

i suspect that thinking is similar to the ideas people had that got them to buy hybrid cars because of EV range anxiety.

but hybrid cars are saddled with a maintenance heavy complex system that isn't used much.

nowadays we know the solution is just a bigger EV battery.

Hydrogen is a storage medium. It's fundamentally different than natural gas. Think of it more like a more complex, expensive, and inefficient battery; with the only advantage being that you can store more energy per unit volume at large scales.

I don't think parent was against gas because of its physical but rather because it's a fossil fuel
