French fuel and energy multinational ST Energies has signed a memorandum of understanding (MoU) with a Shell filling station in Worcerster, in the Western Cape, to implement a sustainable solar solution that will allow the station to achieve carbon-neutral status. The initiative is designed to deliver reliable power to filling stations using a combination of solar photovoltaic (PV) panels, batteries and liquefied petroleum gas (LPG) backup to keep them off the grid and operational.
