The Future of Fuel Cells and Batteries

The IEA is projected that anything operating over roughly 400 kilometers between refueling stations is probably going to end up being hydrogen fuel cell. There's nothing to say that a tractor trailer or a train or what have you can't be both hydrogen fuel cell and batteries. And it sounds like there's obviously still kind of this race in terms of where will we finally land in terms of battery chemistry, range and so forth.
