The question was specifically about home hydrogen. Yes, it makes sense for utility companies, as well as large vehicles, as I said before. It’s a great solution to turn renewables into a shipable commodity. Home use though doesn’t make sense. A regular battery has much better properties for home use.
The same applies for home hydrogen storage too. Compressed hydrogen is good for months. Another option would be metal hydrides which apparently last a long time too. The problem is that you simply cannot power your house entirely with batteries alone.
Even in tank form, you can store it for months. It is not much different than CNG.
Large-scale solutions matter too. The utility companies can utilize such a thing.
