For sure, field charging of tanks should be through DC. But H2 is the solution for energy abundance that is 100% renewables based. To have enough energy every day from renewables needs surpluses on most days, and H2 production is the best use of those surpluses because it is transportable/exportable energy that happens to be cheaper than electric transmission.
