Like Sant's team, Planetary Hydrogen is extracting carbon from seawater, trapping it in a solid, and indirectly making hydrogen gas. Rather than using electrolysis, however, they're doing it with hydroxide. Hydroxide is an alkaline material that speeds up what is otherwise a natural process—rocks reacting with carbon dioxide and water to ...
