Methane storage is cheaper than batteries, but hydrogen molecules are so small that the cost of storing it is actually pretty high.

- pfdietz 3y agoThe cost of capturing the carbon to make the methane ruins your idea.
- suoduandao3 3y agonot my idea, I prefer batteries. But Methane storage would be above hydrogen storage in my hierarchy of things I'd allocate capital to. I can see why I sounded in favour of methane over batteries but I was just acknowledging the OP's point about dollers/joule stored. Batteries have plenty of other advantages that I think put them ahead despite that figure.
- pfdietz 3y agoI don't see why you'd prefer methane storage. You're straining mightily (capturing CO2, synthesizing methane) in order to save on storage caverns, which are cheap.
- suoduandao3 3y agoI wasn't aware hydrogen storage in salt caverns was a thing, I had been thinking of a 'metal tanks' solution similar to gas stations which I know leads to major issues with corrosion.
