Yeah though hydrogen is produced by burning fossil fuels currently. I hope the tech to get hydrogen from the air and water using solar keeps improving and getting cheaper to the point that it becomes the main source of hydrogen. As hydrogen used as a fuel source and as a way to store renewable energy has a huge potential to bring down the world's carbon production.
I'm skeptical about hydrogen's use as a form of energy storage but a carbon neutral source of hydrogen for chemical processes, especially the generation of fertilizer, would be a huge deal.
