Europe’s scramble to find new sources of energy to reduce its reliance on Russia has given Sasol, South Africa’s biggest fuel producer, a new purpose to accelerate its green hydrogen plans. Sasol is focusing on green hydrogen — made by machines called electrolyzers that are powered by the wind and sun — in South Africa’s northwest coast. The company is doing a feasibility study that it expects to complete in two years, according to Sasol’s CEO Fleetwood Grobler.
