Hydrogen is part of the answer, for steel and perhaps concrete manufacturing. And also to fuel container ships, in the form of ammonia. But as a storage medium it is not very efficient. At least not now.

Round-trip efficiency is not very important for a backup storage medium when the marginal cost to produce is zero.

Other considerations drive choices, then, e.g. capex, transportability, usefulness for other processes.

And once you realize that nearly all renewable energy production has a marginal cost of zero, then it quickly becomes the overwhelmingly best idea for energy storage.

The infrastructure needed for hydrogen production and storage is far, far, from zero.

Yet, the marginal cost of producing hydrogen using that infrastructure is zero: the only inputs are water and energy, and the marginal cost of that energy is zero.
