they STILL built an additional gasification plant (Segunda).

You do know they built that 3 decades ago, right?

The first half of Secunda CTL, completed in 1980, cost U.S.$3.2 billion in dollars of the day. Sasol 3 (the mirror-image of Sasol 2), completed 1984, cost $2.5 billion in dollars of the day.
