New electrolyser technology could cut ammonia costs

A new type of electrolyser cell that produces highly pressurised hydrogen could greatly reduce the levelised cost of ammonia, developer tells Hydrogen Economist

New technology processes to produce green ammonia from hydrogen could result in a 21pc fall in the cost of the derivative fuel compared with traditional processes, according to a government-sponsored study by the technology’s developer, Supercritical Solutions. The ‘GreeNH3’ study, carried out with UK energy firm Scottish Power and ammonia technology company Proton Ventures, explored the potential for integrating these new technology processes into a traditional Haber-Bosch ammonia production process. 85pc – Efficiency of fuel cell Supercritical has filed multiple patents for a new electrolyser cell design that removes the need for a membrane and precious group metals and enables hig
