SUISO begins construction on mega coal-to-fertiliser and methanol project in South Africa

• SUISO is taking a decisive step toward sustainability with a US$1.7-billion (R31.5-billion) coal-to-fertiliser and methanol project in Kriel, Mpumalanga.
• SUISO specialises in blue ammonia production.
• Blue ammonia is produced from hydrocarbons where the CO2 emitted during production is sequestrated via carbon capture utilization & storage (CCUS) technology.

“We’re redefining what’s possible in the fight against climate change while addressing the critical need for food security,” says Paul Erskine, SUISO Founder. “This project isn’t only about producing sustainable fertilisers and zero-sulphur methanol; it’s also about proving that decarbonisation and industrial innovation can work hand-in-hand.”

The SUISO facility will employ advanced carbon capture and utilisation systems to significantly reduce emissions. Captured carbon will be repurposed for gypsum and ammonium carbonate production, converting waste into valuable resources for agriculture and construction. This aligns with global efforts to minimise industrial emissions while maximising resource efficiency.

Located on a 900-hectare site, the facility integrates feedstock and production processes to ensure efficiency and affordability.

Feasibility studies are underway for carbon storage in deep saline aquifers, ensuring long-term environmental benefits. Furthermore, SUISO’s integrated coal gasification process generates synthetic gas, hydrogen, and ammonia, forming the foundation for fertilisers and zero-sulphur methanol.

To support its decarbonisation goals, SUISO is exploring a 15-year power purchase agreement with a leading renewable energy provider. This collaboration will integrate renewable energy into the national grid, reducing reliance on coal-based power and setting new standards for sustainable industrial operations.

SUISO’s facility will implement wet flue gas desulfurisation and advanced water recycling systems to meet international emission standards. These technologies will reduce nitrogen dioxide and sulphur dioxide emissions, addressing long-standing air quality concerns in Mpumalanga. Additionally, the production of 234 000 tons of clean, zero-sulphur blue methanol annually ensures compliance with South Africa’s upcoming Fuel Act of 2027.

The project’s construction phase will generate 4 000 jobs, transitioning to 981 permanent positions once fully operational in 2029.  To build a skilled workforce, the onsite Gerhard Potgieter Engineering Training College will upskill 400 employees, fostering sustainable development and economic resilience in Mpumalanga.
