Synthetic methane production has a theoretical maximum efficiency of 30-40%. So we'd need to build 3x as much power and is actually needed, and a bunch of electrolysis and Sabatier reaction plants on top of that.
Or we can just follow France's example and build nuclear plants.
- cygx 7y agoThose numbers are outdated. Round-trip efficiencies of up to 80% have been claimed: https://www.sciencedirect.com/science/article/pii/S0360544218320693 https://www.sciencedirect.com/science/article/pii/S036054421... If that's legit and can be made cost-effective, the case for nuclear is largely gone...
- manfredo 7y agoEfficiencies of over 100% have been claimed. Over 50% of the US patent office's applications are for entropy-reversing devices. Come back to me once these claimed figures are actually implemented.
- cygx 7y agoReverse fuel cells aren't magic, though. I agree that 80% seems rather ambitous...
