Methods & Concepts

Sasol’s 2030 target is contingent on the company reducing its coal usage for both power generation and production from 40 Mtpa to ~31 Mtpa. To achieve this, Sasol has committed to implementing a number of key actions:

• Scaling up renewable energy: By 2026, Sasol intends to introduce 600 MW of renewable energy to replace the use of coal for electricity generation at Secunda. Sasol, together with Air Liquide, is in the final stages of concluding power purchase agreements (PPAs) with Independent Power Producers (IPPs) for delivery of this power, of which 200 MW of will be allocated to Sasol and 400 MW to Air Liquide. On 24 January 2023, Sasol announced the finalisation of PPAs for the delivery of 220 MW wind power to Secunda, and for the supply of 69 MW wind power to Sasolburg. By 2030, Sasol intends to scale up renewable energy capacity at its Secunda site to 1 200 MW.
• Increasing gas uptake: A significant share of the reduction in coal usage will be achieved at Secunda through the substitution of coal-based feedstock with natural gas feedstock for conversion into fuels and chemicals. This will require Sasol to replace some of its existing coal gasifiers with gas reforming capacity, and secure additional gas supply.
• Process and energy efficiency measures: Sasol intends to implement a suite of process and energy efficiency projects within its operations to enable further reductions in energy and feedstock (and therefore coal) usage.
• Implementing a ‘fine coal solution’ : There may be process and feedstock management efficiencies to be realized through briquetting of coal fines for re-use in boilers.
