Carbon neutral is a fossil industry marketing gimmick. The climate does not care about provenance of CO2, it only cares about its presence.
We need to de-carbonize, and hydrogen produce by renewables such as wind qualifies.
- zokier 7y agoGrowing biomass removes co2 from atmosphere. Burning carbon from that biomass releases it back. Make the process efficient enough (with addition of external power) and you end up with no added co2 in atmosphere. That's not just a marketing gimmick. Of course it is debatable if it is an efficient approach for doing things, but the concept is sound
- brnt 7y agoThere is no net reduction of co2 emissions here, that's why its marketing. The fact that sequestration in plants happens first does not make it better for global warming if you then burn it right after. Encouraging plant growth on top of a decarbonized energy cycle, now that will make a difference.

- wffurr 7y agoI am not so sure that hydrogen is the best energy storage medium for using renewable energy for transport. The handling properties of biodiesel and synthetic gasoline likely outweigh and efficiency losses.
