Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

yeah hydrogen to the house might not make sense. after all, gas can only be used for heating / very specific applications (steel reduction, ammonia production) while electricity can be used for everything. most humans want that flexibility in their home. so electricity is better for that. and since you already have electricity, no need for gas anymore. lower fixed costs if you only need to build 1 cable instead of 1 cable + 1 pipe.
i meant hydrogen can be stored for a year or longer and used for industrial processes where it can be piped to. steel furnace, for example.
i read up and producing hydrogen (electrolysis) has 80% energy efficiency. storing it (high pressure at 700 bar) consumes 12% of the energy in the hydrogen. source (german wikipedia on the topic). so production + storage has a total of 70% efficiency. which is pretty good i would say. especially considering for how long you can store it that way.
