The advantages of a chemical fuel is that you make them when costs are very low and save them for when you need them. Even months later if need be. Not doable with batteries. Even the ICCT is admitting that electricity used to make hydrogen is going to much cheaper than electricity used to charge BEVs. It will likely be cheaper to operate a hydrogen car due to that fact.
At least with e-fuels, there’s an argument to be made that there are too many unnecessary steps and that costs will be high. But with hydrogen, that argument doesn’t really hold water. Fuel cell cars are also EVs. The gap between BEVs FCEVs on efficiency is small and shrinking. When the full lifecycle factors are included, it is likely the FCEV is the more efficient idea even now.
Hm, maybe, but using it in a vehicle doesn’t sound too enticing. Although everything we talk about here is developing technologies, maybe the next breakthrough might change everything.
… But they are way more inefficient then batteries, which is what I’ve been saying all this time.
Which doesn’t matter, something I’ve been saying all this time.
And the efficiency of batteries has been massively exaggerated too.
energy prices are far from stable and efficiency plays a huge role in the feasibility of a technology.
The efficiency of e fuels is far below hydrogen and hydrogen is still a lot worse than battery.
