Hydrogen isn't an energy source it's an energy storage mechanism. You create hydrogen from other sources. Most commercially available hydrogen comes from natural gas already. So you're wasting a ton of energy by converting the natural gas to hydrogen and then burning it again. Hydrogen is just another form of battery.
- pfdietz 6y agoIf you convert natural gas to hydrogen, you can sequester the CO2 produced. The hydrogen production facility can operate 24/7, with the hydrogen stored and only being used when necessary. In this way, natural gas could continue to back up renewables (or back up renewables + short term storage) without CO2 emission, at a capital cost per kW far below nuclear plants. (The same argument applies to "green hydrogen"; which would be chosen would depend on economics.)
