The swedes and icelanders are using geothermal to process their water.
No known CO2 waste stream from that electrolysis. Actually have the
plants next to the H2 pumps. Think it is BP running that. Solar PV
also was mentioned IIRC.

The latter I don't know about, but the "hydrogen economy" is a load of
bunk. All commercial hydrogen comes from coal fired electrolysis
plants or processing of natural gas with the release of all the carbon
as CO2. Sure, it will only produce water and electricity in a fuel
cell (that does not currently fit inside a car and costs $30,000 or
so), but you have to MAKE the hydrogen from somewhere -- it is never
free in nature.
