A potential use for this would be to use the hydrogen as a way to cheaply store the energy to be used when the sun is not shining. I.e. Pair it with fuel cell tech to generate electricity at night.
In this scenario the price of the tech should be compared to solar + batteries per kWh, and I could imagine that at scale hydrogen storage could beat out the cost of betteries.
- pkphilip 5y agoEnergy density is another big factor. Hydrogen has a much higher energy density especially for automobile use compared to batteries.
- zizee 5y agoMy opinion, fwiw, is that batteries have won the day in the automobile space. The infrastructure investment required to make hydrogen work for automobiles must be astronomical vs incremental improvements required to the existing electrical network. Couple this with the fact hydrogen distribution and storage have some significant problems, plus recharging at home/work/parking is super convenient. The only real thing stopping battery powered electric cars from being the obvious first choice in many markets is the cost of battery packs. Conveniently this has progressively improved yer-on-year. It is simply a matter of time.
