That’s where it comes from presently because we haven’t started producing significant amounts of green hydrogen yet. “This tech is useless because we aren’t doing it yet!”
Constructing large solar and wind arrays in remote / uninhabitable areas is not free, but the land is “free” because in many cases it’s not suitable for any other use. I think a lot of people dreaming of a wind & solar renewable future underestimate the physical area required to capture enough sunlight to power everyone’s EVs.
