FC Posted May 21, 2021 Report Share Posted May 21, 2021 I've been buying some platinum, so with all the talk of these zero-emission engines, I wondered how they work? https://www.edmunds.com/fuel-economy/8-things-you-need-to-know-about-hydrogen-fuel-cell-cars.html Quote Link to comment Share on other sites More sharing options...

Dr.Hess Posted May 22, 2021 Report Share Posted May 22, 2021 There needs to be a breakthrough in cracking the hydrogen off of something. Splitting it off of water or natural gas as they describe is not cost effective. It's just an interesting toy at this point. Also, it is very difficult to completely seal off hydrogen. H2 is the smallest of molecules. No matter what you put it in, it will escape, literally through the walls. Maybe not enough to matter, but it's interesting.

FC Posted May 23, 2021 Author Report Share Posted May 23, 2021 You mean the production of the hydrogen, right? I hope so, because cheaper hydrogen production would be a great thing. Quote Link to comment Share on other sites More sharing options...
Dr.Hess Posted May 23, 2021 Report Share Posted May 23, 2021 Yes, production. Sort of. It's not like it is produced, just split off of something else. Being the most abundant atom in the universe, there's plenty around, but it's all stuck on to something around here, like water, oil, natural gas, and actually everything else. The energy needed to split it off of water, for example, will be more than the energy you will get back combining it with oxygen in the fuel cell to get electricity. Where do you get that energy? Nukes? Oil? Coal? Then how is a hydrogen "car" going to be "green"? Solar? That has a lot of energy issues, like a 20 year break even point on a product with a 20 year life cycle.

FC Posted May 23, 2021 Author Report Share Posted May 23, 2021 They used to get the hydrogen by using a lot of electricity to break it from H2O, but it appears to be a much more efficient process now, but there's still more efficiency needed.
