Hydrogen would be a terrible approach due to the low round-trip efficiency and the need to store huge amounts of compressed/cryogenic gas, but iron air batteries seem like they could actually do this.
- Taek 1y agoMost people have the wrong idea about hydrogen fuel cells because the media almost exclusively talks about them in the context of cars. When your fuel cell can be stationary and heavy and large, you can hit efficiencies above 50% without cogeneration and above 80% with cogeneration.
- matthewdgreen 1y agoDoes that number include electrolysis? I didn’t realize that kind of round trip efficiency was possible.
- Taek 1y agoYes it does!
