I drove 1800 miles in a Hydrogen Car

With a decent range of 400~ miles (Mirai), minimal fuel-cell degradation, and the fact it can store hydrogen for many years is certainly enticing. The process of generating hydrogen doesn't really matter so long as renewables are used. The only thing lacking is infrastructure, flexibility to refuel anywhere, and better global adoption with more companies doing R&D. Unfortunately, there are zero viable stations to refuel.
