Could you please expand on this? My understanding was that hydrogen was produced through electrolosys. What process does one use to go from a hydrocarbon to H2? And does that process produce CO2?

Unfortunately, the electrolysis of water is not efficient enough to produce enough H2 on an industrial scale at the moment. Most H2 is produced by steam reforming of gas: https://en.wikipedia.org/wiki/Hydrogen_production https://en.wikipedia.org/wiki/Steam_reforming

The first link says that the efficiency is 80%. Seems like that’s enough to scale, especially if electricy prices go negative during peak hours of renewable energy production. So I’m still trying to understand what the roadblocks to this are.
