JOHANNESBURG (miningweekly.com) – Green hydrogen and fuel cells will be a very important part of any future energy system, says Switzerland-based energy and sustainability consultancy strategist Dr David Hart.
Among the electrolysers that convert renewable electricity into green hydrogen are proton exchange membrane (PEM) electrolysers, with PEM fuel cells then converting the green hydrogen back into green electricity for mobility and stationary power. Both technologies are reliant on platinum group metals (PGMs), which are sourced overwhelmingly from South Africa.
Hart, who was speaking to Engineering News & Mining Weekly in a Zoom interview, leads the green hydrogen and fuel cell work of E4tech, which is part of the 40-country, 160-office ERM Group of Companies. (Also watch attached Creamer Media video.)
