Green Methanol Project Advances In South Africa

The South African province of Gauteng is set to see development progress on the country’s first wastewater-to-green-methanol plant.

In mid-May, a team of Climate Fund Managers (CFM) and Invest International signed a development funding agreement with the local Green eFuels Producers (GeFP) for the project. The facility will be located in the Vaal special economic zone (SEZ) and will process about 90,000 tonnes a year (t/y) of municipal sewage sludge from the Sebokeng wastewater treatment plant, producing an estimated 14,300 t/y of green methanol.

The development funding is being provided by Climate Investor Three through its affiliate SA-H2 Fund, a blended finance facility managed by CFM in partnership with Invest International. CFM is a joint venture of Dutch development bank FMO and South Africa’s Sanlam Group, while Invest International is a joint venture of FMO and the Dutch government.

The plant will be powered by renewable energy, including 50MW of co-located solar power and additional wind power procured through South Africa’s wheeling framework, which will be used to power a 10MW electrolyser to produce green hydrogen. It will create up to 300 construction jobs and 60 permanent operational roles.

The waste-to-fuel facility will lay the foundation for the development of the Green Methanol Corridor, planned to stretch from Gauteng to the KwaZulu-Natal province, with the Port of Durban as the point of sale.

Up to Rand 65.8 million (US$4 million) of funding has been committed to support project development, including technical and engineering design, environmental and social impact assessments, permitting and commercial structuring required to advance the project towards financial close. The agreement also secures the fund’s right to participate in equity funding for up to Rand 430 million (US$26 million).

The green methanol project is at the prefeasibility stage and a bankable feasibility study is set to be undertaken. Financial close is targeted for the second half of 2027, with commercial operations to begin in 2029.

Wastewater treatment facilities generate sewage sludge as a by-product and managing this material sustainably is a growing challenge for utilities in South Africa. By converting it into green methanol, the project diverts waste from conventional disposal pathways while creating a fuel that is emerging as a low-carbon alternative fuel in sectors such as shipping, power generation and aviation – industries that are difficult to decarbonise.

In addition to producing sustainable fuel, the project will return approximately 50,000-60,000 cubic metres a year of industrial-grade water 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 socioeconomic upliftment in the region.

Also known as CI3 South Africa, the SA-H2 Fund is an energy transition and green hydrogen fund that is also supported by the Development Bank of Southern Africa (DBSA) and the Industrial Development Corporation of South Africa (IDC). It is aimed at promoting the development of South Africa’s energy transition and green hydrogen sector markets. Another financing partner is the European Commission, through the EU-South Africa Global Gateway investment package.

Germany’s FEV Consulting, the Netherlands’ INM Operations and German development bank GIZ are supporting the development of the waste-to-fuel scheme.

In an exclusive interview, ConstructAfrica talked to CFM’s investment director Muhammed Hajat and investment associate Sam Kanyenze about the strategic importance of the green methanol production facility for South Africa and the continent.

Q) How important is the project for South Africa?

The GeFP green methanol project is a pioneering project – it is currently the only green methanol project on the African continent tracked by the Methanol Institute's global database of roughly 263 renewable methanol projects worldwide, positioning South Africa as an early mover in an emerging global clean fuels market.

Beyond that distinction, it sits at the intersection of several critical national challenges: strained wastewater treatment infrastructure; the need for industrial decarbonisation; and South Africa's ambition to become a green hydrogen and green fuels export hub.

By converting 90,000 tonnes of sewage sludge per year into approximately 14,300 tonnes of green methanol, the project simultaneously addresses a waste management crisis in the Vaal region and produces a clean fuel with significant export value.

It is also expected to create 300 construction jobs and 60 permanent operations roles, and to supply industrial-grade water back to the local water utility – directly benefiting the wider Vaal community.

Q) Why were South Africa and Gauteng chosen as the project location? Do we know who the contractor will be and whether local firms will be preferred?

South Africa offers a compelling combination of factors that are difficult to match elsewhere on the continent. It has abundant, low-cost renewable energy resources, established export infrastructure, supportive government policy frameworks – including the Green Hydrogen Commercialisation Strategy and the Hydrogen Society Roadmap – and a network of [SEZs] designed to attract exactly this kind of green industrial investment.

Gauteng specifically, and the Vaal region in particular, was selected because of the concentration of wastewater treatment infrastructure managed by Rand Water, one of Africa's largest bulk water utilities. The Vaal SEZ further derisks the project by offering long-term land tenure and shared infrastructure, and it is advancing a climate-resilient industrialisation programme in which GeFP has been identified as a key anchor tenant.

The engineering, procurement and construction (EPC) partner will be selected post the front-end engineering and design (FEED) process through a rigorous competitive process. Local firms will be considered as part of this process as well. The FEED contractor will be selected through an RfP [request for proposal] process.

Q) Is the project scalable? Are there more impactful projects like this in the pipeline in South Africa or the continent?

Yes, scalability is central to the design philosophy. The project is conceived as the first development under the broader Green Methanol Corridor Programme (GMCP), which aims to replicate the hybrid PtX/BtX [Power-to-X and Biomass-to-X] model across multiple sites using municipal wastewater sludge. The Vaal SEZ land parcel of an estimated 697 hectares offers substantial room for future expansion beyond the 3.2 hectares currently earmarked for the project.

SA-H2 Fund's mandate is specifically to invest in the development, construction and operation of energy transition and green hydrogen value chain projects across South Africa.

The fund, therefore, tracks high-impact projects within this value chain, with the aim of facilitating South Africa’s nationally determined contribution (NDC) goals.

Q) Tell us more about the Green Methanol Corridor and its planned components.

The GMCP is GeFP's broader ambition to develop a network of hybrid Power-to-X/Biomass-to-X green methanol plants across South Africa and beyond, each using municipal wastewater sludge as a primary feedstock combined with renewable energy (solar PV [photovoltaic] and wind).

The model is designed to be replicable wherever there is a concentration of wastewater treatment infrastructure and renewable energy availability.

Q) How important is the sourcing of development funding to kickstart innovative projects such as this?

It is absolutely critical and this is precisely why blended finance vehicles like SA-H2 exist.

Innovative infrastructure projects face the greatest funding gap in their earliest stages, before a bankable feasibility study has been completed. At this point, projects are perceived as too risky for most commercial lenders, which typically require key technical, commercial and regulatory risks to be reduced before investing. Without early-stage development capital, many projects face significant delays or fail to progress at all.

Development funding plays a catalytic role by helping projects reach bankability and crowding in the commercial capital needed for construction. SA-H2 combines public and private sector finance within a single facility. The public capital is deployed strategically to support early-stage development, thereby removing or reducing risk and unlocking private investment to fund project construction.

Q) Has the current geopolitical crisis and ensuing fuel shortage accelerated the procurement of funding for this project?

The geopolitical environment has certainly sharpened the focus of both investors and governments on energy security and the diversification of fuel supply chains. For green methanol specifically, the structural drivers are regulatory as much as geopolitical – the EU's Renewable Energy Directive III mandating renewable fuels of non-biological origin, the IMO's [International Maritime Organisation] 2050 decarbonisation targets for shipping, and the EU’s Carbon Border Adjustment Mechanism (CBAM), which is expected to expand to cover chemicals and alternative fuels, and will increase the cost-competitiveness of green methanol versus fossil-derived alternatives in European markets.

The expectation is for financiers to increase capital allocation towards funding of green fuel projects to diversify supply and prevent risks of fuel shortages, which can be detrimental to global supply chains.

Q) How important is green methanol now in light of the IMO's drive towards zero-carbon shipping?

Extremely important. The IMO has set a target of 50% reduction in shipping greenhouse gas emissions by 2050, with zero or near-zero fuels required to constitute at least 5% of international shipping energy by 2030.

Green methanol is emerging as one of the leading candidates for this transition, alongside green ammonia, because it is liquid at ambient temperature, relatively safe to handle and compatible with adapted internal combustion engines. The global green methanol market is projected to grow from US$2.9 billion in 2025 to more than US$41 billion by 2035, a compound annual growth rate of about 30%.

GeFP's offtake strategy targets the shipping sector as one of the key offtake markets, alongside chemicals, energy and aviation.

Green Ammonia Plant

Meanwhile, SA-H2 has also invested in Hive Hydrogen’s US$5.8 billion Coega green ammonia plant in the Eastern Cape province. The facility will have a capacity of 1 million t/y in the first phase. The green ammonia will be exported to Europe and the Far East.

According to CFM investment manager David Frank, the project is approaching the final stages of development with the FEED due to commence in the near term. The FEED’s completion will be a critical milestone toward securing binding offtake agreements and reaching final investment decision (FID).
