We need an all of the above approach to climate change. There are some sources that will take a long time to decarbonize, at some level we’ll need carbon capture as one piece of the puzzle.

It’s kind of like The Ocean Cleanup. Yeah there’s way more plastic going in and reducing that should should be first priority, but at some point we have to take some out as well and it’s worth figuring out how to do it at scale

It refers to how the hydrogen is produced. “Green” hydrogen is produced using a electrolysis process powered by renewable energy. “Blue” hydrogen is created from a chemical reaction involving natural gas, and the CO2 from the blue hydrogen process is then captured and stored, making it theoretically carbon neutral (however, it is criticized for the inevitable methane leaks and such from the process). “Grey” hydrogen is the same as blue hydrogen but the emissions aren’t captured and stored.
