Hydrogen vs. Battery Electric Cars

Strangely I do not see an important point mentioned. At the part where it's explained that the hydrogen efficiency is worse, one should point out that there is a big advantage though that hydrogen is its own storage. The moment of hydrogen production does not need to be exactly synchronized with demand/charging. You make hydrogen when there's excess eg. wind power. Then you just keep it in tanks until it needs to be pumped to the vehicle. This way, the power grid itself does not need significant amounts of grid storage to satisfy demand independent from variable generation.
