The infrastructure needed to create a power grid for people to charge electric vehicles at home would be double-bonkers.

Upgrading fueling stations seems much easier than mining all of the copper needed to add all of the extra lines for EV charging, and then upgrading the whole national grid.

Supposedly one company has claimed 95% efficiency on creating hydrogen from electrolysis:

Power that by nuclear energy, and it's a green & clean winner.

Any grid good enough to air condition every house in the day time is good enough to charge electric cars at night.
There are ancillary benefits to upgrading the grid that retrofitting pipes to pump hydrogen doesn’t bring. Most of America and Europe would do just fine without upgrades, for most of the population. And the jurisdictions touting hydrogen (e.g. Japan) have 70s-era anti-nuke greens in power.

Hydrogen is a smart hedge to pursue. But thank goodness it’s mostly Japanese tax dollars doing it.

Current Japan regime isn't anti-nuclear but they are the regime that encouraged nuclear plants. Now nuclear is unpopular for obvious reason so the regime is struggling about future energy plan. Thanks (/s) to putin, nuclear is now re-evaluating. I feel Germans are more anti-nuclear.

Why Japan encourages hydrogen is not very related to nuclear (except that the gov want to feed jobs to heavy industry companies that worked on nuclear), but related to lack of every local materials/fuels. I think hydrogen research should be encouraged, but Toyota should release more PHEV/BEVs early.

There's already tons of available lines going to a ton of people's homes. It only took a dozen or so feet of cable to add a 14-50 outlet in my garage.

Their homes were built expecting them to be able to pull 150-200A of power. It doesn't take that much power to charge an EV overnight. Mine charges way faster than it needs to on 32A 240V.
