Not necessarily. (1) There are losses transporting in storing electricity. If hydrogen was made on the spot, and if the losses storing and transporting hydrogen were smaller (unlikely), that would be a gain. (2) Hydrogen can be produced at solar peaks, when energy prices turn negative, and stored... huge (net) efficiency gain!
- _ph_ 7y agoWhy not charge 2-3x as many cars during the solar peaks? Hydrogen might be in the far future for long-term storage of electricity, but then it will get used to power the grid in times of lacking sun/wind, rather then propelling cars.
