Episode 522 - Making hydrogen greenly from Seawater

​Hydrogen comes in all kinds of colours but what does that mean? Hydrogen has a role to play in a decarbonised world as long as we can produce it greenly. It's no good producing green hydrogen if you use up another valuable resource or create another kind of waste. Water water everywhere, but not a drop to electrolyse. Using seawater to make hydrogen has challenges. How can we use the abundant seawater resource to make green energy sources without producing nasty by products?  Suraj Loomba, Muhammad Waqas Khan, Muhammad Haris, Seyed Mahdi Mousavi, Ali Zavabeti, Kai Xu, Anton Tadich, Lars Thomsen, Christopher F.
