I still believe there is potential for hydrogen/ammonia/methane fuel to be a seasonal storage mechanism. Battery technology does not seem capable of offering grid scale storage for the entirety of Winter. While the solar->fuel->electricity conversion takes huge efficiency hits, for “free” renewable energy, it can still pencil out as economical. Plus, it is feasible today without unobtanium (but not currently cost competitive vs fossil fuels)
- theshrike79 3y agoHydrogen is _really_ hard to store. It leaks from every container, transport and storage losses are just an accepted fact. It might be a good option when we have so much renewables that we can't find any more batteries to shove it in. Then we can use it to store compressed hydrogen, that can be released as electricity from large-scale fuel cells during calm cloudy days.
- redox99 3y ago> seasonal storage mechanism Is this even needed? With solar, wind, etc storing more than a few days worth of energy seems very wasteful.
- 0cf8612b2e1e 3y agoAvailable solar energy is significantly lower in winter. Additionally, heating typically requires more energy than cooling, so it is a double whammy. Solar alone cannot generate sufficient power without ludicrous over provisioning which would be wasted the majority of the year.
