I have always wondered why electrolysis didn't get more attention as a storage option for renewables. How hard can it be to store a bunch of hydrogen gas? Or, apparently, convert it to synthetic fuels that we already know how to store.
Also, you suck CO2 out of the atmosphere while generating the gas, right? And eventually you burn it, which could release that CO2 back, but suppose instead you capture it. Wouldn't this then be negative carbon electricity? And if you scaled it up enough, could it actually put a dent in rising CO2 levels and even allow us to regulate CO2 levels to stabilize climate?
- adrianN 5y agoI believe that the current installations use CO2 from a concentrated source like the exhaust of a gas turbine to make things easier. Gas has the big benefit that we already have infrastructure to store and distribute it. I think all (developed?) countries have infrastructure for strategic gas reserves that can store months worth of natural gas.
- civilized 5y agoSo best case scenario is probably just carbon neutral, as you'd cycle between a reserve of stored gas and a reserve of CO2 to make new gas when you burn the stored reserves. Still, it'd be way better than what we have now. I wonder if there are any promising companies to invest in, or any ways to make a broad bet on the sector. It'd sure beat sinking my money into the speculative, fossil-burning boondoggle that is BTC.
