No one is powering a house with a battery, or hydrogen, for 100 hours.

Neither are an energy source. We will power houses with low cost carbon-free energy: nuclear and renewables.

For renewables, interconnection and load and generation diversity will deal with most intermittency issues.

We then provide additional firming capacity with other technology, including energy storage, that in the case of batteries, is probably operating every day, and for pumped hydro and other long duration storage that’s probably operating every week or two, and then some fuel-based generation that’s probably only operating a few days a year.

Hydrogen is probably not a big part of the future power system.

I think if you run the numbers microgrids and cheap storage wins vs major grid upgrades and vast transmission networks.

The grid is going extinct when renewables and storage reach their terminal scaled costs.

As Tony Seba so eloquently put it: "you could capture god and force him to generate limitless power forever at the center of a power plant and it would still not be cheaper than decentralized renewables and storage".
