What odor are they going to add to the hydrogen so people can smell a leak?

It would be more efficient to simply use the electricity to directly cook and heat the homes.

However, the primary unstated benefit of this scheme is that the 'energy' can be stored for later use on a demand basis.

How will people determine the 'heat level' of their cooking flame? On a natural gas or propane stove, you can easily view the flame from the burner. Not so easy with hydrogen.

Well charging batteries is probably around 70% efficiency averaged, so as a storage medium, that has to be taken into account comparing apples to apples....

I believe electrolysis is about the same....

I wonder if using the hydrogen to power fuel cells was considered. The end result could be the same. For comparison, is burning hydrogen safer than natural gas or propane?
