Platinum and iridium are the preferred catalysts for producing hydrogen through electrolysis at scale. But they are expensive and rare, offering serious bottlenecks in hydrogen’s plans to replace gas worldwide. Now researchers at the U.S. Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown for the first time that cobalt phosphide can do the same job in the harsh environment of a commercial device: high … [Read more...]
The Clean Hydrogen revolution: how, by whom, when?
Hydrogen rivals oil and gas for storage and hard-to-decarbonise sectors (industry, heavy and long distance transport). But it isn’t all carbon free. “Grey” hydrogen – the cheapest at €1.50/kilo - is made from gas. “Blue” hydrogen depends on the fortunes of carbon capture technology. “Green” hydrogen is CO2 free, but needs further cost reductions in the green electricity used in the electrolysis process. Noé van Hulst, at the Netherland’s Ministry … [Read more...]
