Researchers generate hydrogen more efficiently from water
There are legitimate use cases for hydrogen. Trains are a good example - electrification of medium to long distances (through tough terrain) is prohibitively expensive, as is battery usage for the whole journey.<p>Trains require a lot of energy to get started (where batteries work well), but then a relatively small trickle of power is needed: hydrogen fills this niche. Big companies are investing billions into this right now.
