A Proudly South African green hydrogen mobile solution, which is scheduled to be launched at the African Aerospace and Defence Exhibition (AAD) next month, ticks all the local boxes by making use of a platinum-catalysed hydrogen proton exchange membrane fuel cell (PEMFC) and also being able to accommodate PEM electrolyser technology if need be. Built in response to local and international demand to meet the need for alternative energy solutions, GESS can provide 230 kWh of electrical power to a remote and isolated locations, delivered by solar photovoltaic panels, lithium-ion batteries and the PEMFC.
