- Because off the poor storage efficiency, you will need way more solar panels installed. But when you have more solar panels installed the storage requirement suddenly become way less. Kind of genius.
- In a scenario which more than 50% of the energy demand is used for heating, the efficiency factor of hydrogen storage becomes close to 70% if you are able to utilize the heat energy.
- Instead of distributing electricity over long distances with high loss, you can deliver hydrogen in pipelines with minimal loss and create the electricity amd heat close to the demand.
Conclusion: In places with a cold climate, hydrogen can be used for seasonal energy storage while in regions with a more temperate climate can be used for night/cloud storage. The key here is to utilize the heat from the electrolyzer/fuel cell for hot water and residental heating in order to increase efficiency.
