A very important thing to keep in mind when talking about hydrogen is that is only more sustainable if produced using renewables, which is less than 0.1% of current hydrogen production. If it is produced with fossil fuels, which 99.9 % of it is, it is worse for the environment than burning coal, or conventional jet fuel, for the same energy. https://arstechnica.com/science/2021/08/blue-hydrogen-pushed-by-gas-companies-harms-climate-more-than-coal-study-says/

Usd? Your house must be pretty huge, cost price per watt is about 0.2 usd, if you include shipping and distributor mark ups it's at most 0.5 usd. A 20 panel system of 550w each is 11kw which is 5.5k. A 12kw inverter is around 2k and a 10kw battery should be about 10k making your total cost about 18k usd and between labour and delivery and profit margins I'd say 25k is fair for a 20 panels system. So 75k should be for a 60 panel system and that's way too huge. A family of 10 probably wouldn't even be able to use it effectively enough.
