Fundamentally I agree that FC storage can be very cheap. Just a metal tank with some valves or whatever, right?
a) What stops the fundamentals of batteries from also continuing to get cheaper? Current batteries are using less of some expensive metals, is there some kind of law that is going to make us hit a wall at current battery pricing? I don't see this yet, nor have I seen research papers, but I may have just missed them?
b) The way I understand it, is the cost of creating the Hydrogen is the expensive part now. Is there proof that it will be cheaper with time, and that the end state of producing hydrogen is cheaper than the end state of producing batteries?
- Hypx 6y agoYou need a lot of metal, especially if you want a big battery. Realistically we're not going to see batteries much cheaper than what we have now. Hydrogen is likely to be cost of green energy plus some additional cost factor. So if solar is $0.02/kWh, then hydrogen will be maybe 2x that in the very long run. Everything points to hydrogen eventually getting to around $1/kg, or cheaper than just about any other kind of fuel.
- brianwawok 6y agoThis graph is showing a fall by about another half by 2030 for Lithium Ion https://about.bnef.com/blog/behind-scenes-take-lithium-ion-battery-prices/ https://about.bnef.com/blog/behind-scenes-take-lithium-ion-b... What if there is a different battery technology (not Hydrogen) that allows another half or more fall? Could still be a long ways to go..
- Hypx 6y agoAt some point you just accept that hydrogen is a battery technology with the highest possible energy density and give up on silly in-between ideas.
