Climate Investor Three, through its affiliate SA-H2 Fund - a blended finance facility managed by Climate Fund Managers in partnership with Invest International - has signed a Development Funding Agreement with Green eFuels Producers (GeFP) to support the development of a first-of-its-kind green methanol production facility in Gauteng, South Africa.
The facility will process approximately 90,000 tonnes of municipal sewage sludge per year sourced from the Sebokeng Wastewater Treatment Works. Renewable energy, including 50 MW of co-located solar power and additional wind power, procured through South Africa’s wheeling framework, will be used to power a 10 MW electrolyser to produce green hydrogen. This will enable the production of approximately 14,300 tonnes of green methanol annually, creating a circular waste-to-fuel solution. Once operational, the project is expected to avoid approximately 118,950 tonnes of CO₂ equivalent emissions per year, based on projected annual green methanol production volumes and preliminary lifecycle assessment modelling. It will also create up to 300 construction jobs and 60 permanent operational roles.
In addition to producing sustainable fuel, the project will return approximately 50,000-60,000 m3 of industrial-grade water annually to the local water utility, reinforcing its circular waste-to-value model and supporting improved water security and resource resilience in the Vaal region. The project will also support a Community Development Programme focused on skills development and socio-economic upliftment in the Vaal region.
Mphokolo Makara, CEO of SA-H2 Fund Managers, said: “This project demonstrates the effects of energy transition for industrial operations in the real economy – turning everyday waste into a valuable low-carbon fuel. By transforming sewage into a productive resource, it addresses a key waste management challenge while supporting local jobs and strengthening South Africa’s industrial base through a just transition. It demonstrates how circular economy solutions can play a practical role in decarbonising hard-to-abate sectors.”
Chris Heinermann, Co-Founder of Green eFuels Producers, said: “This investment is a major milestone for our project and a strong endorsement of our vision to produce green methanol using innovative, circular solutions. This project will contribute to decarbonising hard-to-abate industries while addressing local wastewater challenges, creating jobs, strengthening local value chains and generating long-term value for the Vaal region.”
European Commissioner for International Partnerships Jozef Síkela commented: “The EU stands with its long-term partner, South Africa, to support its green transition. Through our €12 billion EU-South Africa Global Gateway Investment Package, announced at the Global Gateway Forum last October, and its unique 360-degree approach, we are working together to unlock opportunities for cleaner growth, skilled jobs, local value chains and innovation, while also strengthening Europe’s energy and economic security. This green methanol project will help deliver lasting benefits for South Africa.”
The project supports South Africa’s Hydrogen Society Roadmap, Nationally Determined Contributions and broader decarbonisation objectives. This pioneering hydrogen-based waste-to-value initiative lays the foundation for a Green Methanol Corridor, enabling scalable green fuel infrastructure across the country.
This marks Climate Investor Three/ SA-H2’s second development funding investment in South Africa, following its investment in Hive Hydrogen’s Coega green ammonia plant in the Eastern Cape Province in 2025, highlighted by the President of the European Commission, Ursula von der Leyen, and President Cyril Ramaphosa at the Global Gateway Forum, which took place in Brussels in October 2025. It also represents the first external institutional investment in GeFP, supporting the company’s plans to develop scalable green methanol infrastructure that can be deployed across South Africa.
