- Because off the poor efficiency, you will need way more solar panels installed. But when you now 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 close to the demand.
Conclusion: Hydrogen might be a good solution for seasonal energy storage especially in places with cold climate. However not a good solution for short term energy storage.
