Many slings and arrows have been lobbed at the idea of outfitting electric vehicles with hydrogen fuel cells instead of battery packs, but the vision of zero emission power on-the-go refuses to die. In the latest development, California is adding a fleet of hydrogen fuel cell trains to its stable of fossil fuel alternatives.
California Gets More $$ For (Clean) Hydrogen
For those of you new to the topic, fuel cell vehicles are electric vehicles, but they don’t use battery packs as their main power source. Instead, fuel cells generate electricity through a reaction between hydrogen and ambient air, assisted by a catalyst. That sounds simple enough, but the aim of bringing down cost, size, and weight can complicate matters (see more CleanTechnica coverage here).
Among other advantages,…
