PEM is the dominant technology
Range of green hydrogen technologies needed – DNV
Firm foresees a role for all four main technologies due to range of necessary applications
Some early green hydrogen projects in Latin America and Africa could already produce hydrogen for as little as $2-3/ kg, according to a report from certification body DNV. The firm foresees a role for all four main technologies—alkaline electrolysis, proton exchange membrane (PEM), solid oxide electrolysis (SOE), and anion exchange membrane (AEM). While AE and PEM are competing for commercial position, SOE has just entered the market via three manufacturers. SOE development mainly focuses on improving the stability and lifetime of the stack, increasing capacity and reducing costs. “We might also see electrolysis offshore on (artificial) islands, platforms, or even integrated into wind
