What the company or idea is
Sasol is an integrated energy and chemical company, founded in 1950 as a state-owned entity—the South African Coal, Oil, and Gas Corporation—to secure fuel independence using German-developed coal liquefaction technology.
How it actually makes money
Sasol makes money by mining coal, converting it into liquid fuels and chemicals via Fischer–Tropsch synthesis, and selling those products alongside electricity and coal tar.
What works
Its vertical integration—from coal mining to fuel refining to chemical manufacturing—delivers stable domestic supply and tax revenue; it remains South Africa’s largest corporate taxpayer.
What does not
Its coal-to-liquids model is capital-intensive, emissions-intensive, and economically vulnerable to oil price volatility—yet Sasol remains the seventh-largest coal miner in the world, not a diversified energy transition player.
What to take from it
Sasol shows how a technologically specific, state-mandated solution (coal-to-liquids) can scale into a multinational industrial conglomerate—but without decoupling from its founding input: coal.
Is it worth your time
Yes—if you are studying how state-backed industrial policy locks in fossil-fuel infrastructure, or how a national energy strategy becomes a global mining and chemicals business.
