HYDROGEN OR LITHIUM? FUEL CELLS OR BATTERIES?

by Bruce Mulliken, Green Energy News

Toyota, General Motors, Honda, Hyundai and Mercedes-Benz are planning to offer new hydrogen fuel cell vehicles to the US in the next few years … at least to the California market.

Does this throw a monkey wrench into plans for a lithium battery electric future? Let's see. Let's compare the two.

 

Lithium is winning right now. But it's the only zero emission game in town. That could change. Fuel cell cars will come on the market. Hydrogen could leap ahead, particularly if Big Oil decides to build filling stations. Lithium could gain a more solid footing if battery prices drop and/or better batteries extend range to hundreds of miles. But then, if batteries don't improve - and quickly - then consumers will be wanting fuel cells. With hydrogen fuel cells looming, it's now up battery makers to scramble to make those better, cheaper batteries.

For what it's worth, if I were The God of Who Decides Energy Technologies I'd pick neither of the above and look for swappable, recyclable metal-air batteries or flow batteries for ALL of our transportation needs of the future. Just sayin'.
