Hopefully solar cells will become cheap enough quickly enough. It would be awesome to have a small hydrogen plant at home.

- _ph_ 9y agoWhat would you use the hydrogen plant for? For the same amount of solar energy, a Tesla is going about 3x further than a Mirai, and a heat pump would provide much more heat your house.
- marcosdumay 9y agoFor energy storage for the night. Open fuel cells storage can be much cheaper than battery based storage. You can store energy for a long period, paying by the maximum power, not storage capacity. That said, molten salt cells look way more promising than hydrogen.
- lokopodium 9y agoMirai is one of the first production HFC vehicles, well below what's feasible. Total solar energy is not really a constraint, refueling time and amount of stored energy are.
- _ph_ 9y agoTotal solar energy is a constraint, as someone has to pay for the cells and to have space to set them up. If you want to power your own car, don't you think it makes a difference whether you need 1x or 3x the area covered with solar cells?
