Chemicals and energy group Sasol is investigating several gas-supply alternatives for its coal-heavy South African operations as it seeks ways to reduce its carbon footprint. The JSE-listed group is simultaneously working on a ‘sustainability roadmap’, which will have a strong focus on lowering its greenhouse gas (GHG) emissions. CEO-designate Fleetwood Grobler tells Engineering News Online that a team of senior executives has been set the task of studying various gas-supply options, including those that could arise as a result of the development of liquefied natural gas (LNG) export infrastructure in northern Mozambique.
