What are the barriers to cheap green hydrogen? As COP28 debates the future of fossil fuels, many people think low-carbon hydrogen could replace them for some uses. But, hydrogen has plenty of problems of its own: water use, public resistance to building infrastructure and above all, its cost.  Ed Crooks talks to three leaders from politics and business, who are trying to find ways to cure these headaches.  Michelle Lujan-Grisham, Governor of New Mexico has launched an initiative to provide a strategic water supply for the industry. Mark Newman is CEO of Chemours, a company that produces a crucial technology for the electrolyzers that can split water into hydrogen and oxygen. John Hartley is CEO of Levidian, a UK-based company that can use methane to make both hydrogen, and graphene – a valuable carbon product. They’ve all been at COP28, talking about how their solutions could help the world get off fossil fuels.
