Really interesting post! Two things: 1. I had heard that the main drawback of hydrogen was that, contrary to oil that can just be dug out, you have to produce it first. And, with the energy inefficiencies in using renewable energy to make hydrogen, it’s not actually that energy-efficient, and even if it were, scaling production would require building masses of renewable power plants and it would basically always be more efficient to use their energy directly rather than through making hydrogen. What do you think of that? 2. Could we have some rough figures of how incredibly expensive those options are, how materials-based storage compares to high-density gaseous storage in terms of costs, etc.?
