Hydrogen makes a great way to store excess energy produced by wind and/or solar farms too.
Efficiency isn't even particularly important - in many cases farms can produce too much power for grids to absorb so you just convert it to hydrogen and use in those rare times you don't have solar or wind power for longer than batteries can absorb.

Efficiency is important if the input (energy) is not free. That's why hydrogen based transport is a non starter because it costs about 3-5x the amount of energy. The other problem with hydrogen is that both storing and transporting it are hard problems. A lot of it just boils off. It takes up a lot of space. Compressing it to 600bar takes up a lot of energy and requires some heavy duty equipment. Etc. Most hydrogen that is currently produced is used on site and not stored/transported.
