Hydrogen has very low energy density compared to gasoline. Like how diesel has more energy than gasoline. It also has a terrible efficiency. I think you lose ~7

It also has a terrible efficiency. I think you lose ~70% from electrolysis.
You also have the problem that most hydrogen today is made from petroleum!
- kolinko 5y agoThat matters for hydrogen cars, which are a terrible idea. But for grid storage energy density doesn't matter too much. Hydrogen, with all it's downsides, is awesome for long term storage because it scales sublinearly with capacity.
