Sasol commissions Envision Energy to conduct green hydrogen design study at Sasolburg facility in South Africa

Sasol has formally commissioned Envision Energy to carry out a design study for a green hydrogen system at its Sasolburg operations in South Africa. The collaboration went public during the South Africa-China Energy Investment Conference, where the partnership was showcased at Envision’s Chifeng Hydrogen Net Zero Industrial Park in Inner Mongolia.

The study marks an early but concrete step in figuring out how renewable energy, storage, and electrolyzer technologies could support lower-carbon fuel and chemical production at the Sasolburg site.

Sasol and Envision Energy launch green hydrogen design study at Sasolburg

Sasol tapped Envision Energy to run the design study, and the partnership surfaced at a high-profile diplomatic moment. South African Minister of Electricity and Energy Dr Kgosientsho Ramokgopa was present at Envision’s Chifeng Hydrogen Net Zero Industrial Park in Inner Mongolia, where the collaboration was showcased as part of the South Africa-China Energy Investment Conference.

Envision Energy describes itself as a global green technology company, with a portfolio spanning wind and solar energy, battery storage, and hydrogen infrastructure.

The timing gave the announcement real weight. Unveiling an industrial design partnership during a ministerial visit and bilateral energy conference signals that this isn’t purely a technical exercise — it carries commercial and diplomatic significance for both countries.

The design study will assess how renewable energy generation, battery storage, and electrolyzer technologies can be integrated to support green hydrogen production at Sasolburg. That phase is expected to wrap up later in 2026, after which Sasol will have the technical and commercial data needed to evaluate what comes next.

Why Sasol is pursuing green hydrogen at Sasolburg

Sasol isn’t starting from scratch. One significant reason Sasolburg was chosen for this study is the existing industrial infrastructure already on the ground. Rather than building entirely new facilities, the company is exploring how proven assets could be adapted to support a lower-carbon production model — a more pragmatic path than greenfield development.

Green hydrogen fits into that picture as a potential feedstock for cleaner fuel and chemical value chains, areas where Sasol has long-standing expertise. Envision Energy’s integrated solution was selected to assess whether cost-competitive green hydrogen production is actually achievable at the site, combining renewable generation, battery energy storage, and electrolyzers that optimize output based on forecast energy availability and pricing.

Danie Cronje, Sasol’s Senior Vice President for Business Building, put it directly: “By drawing on leading global expertise, we can evaluate how these technologies may contribute to future lower-carbon fuel and chemical value chains, while building on Sasol’s existing industrial capabilities.”

Potential outputs: eMethanol and sustainable aviation fuel

If the design study produces favorable results and investment decisions follow, Sasolburg could become a production site for eMethanol—a low-carbon fuel and chemical feedstock made using green hydrogen and captured carbon dioxide. The facility could also potentially produce sustainable aviation fuel, known as eSAF, though that outcome depends on further investment approvals.

Both products represent growing markets. Demand for low-carbon fuels in industrial and aviation sectors is rising, driven by regulatory pressure and corporate decarbonization commitments, and eMethanol and eSAF rank among the more commercially promising pathways for green hydrogen utilization.

Envision’s system plays a key role in making the economics work. By forecasting energy availability and pricing across its renewable generation, storage, and electrolyzer components, the integrated platform is designed to optimize hydrogen output and manage costs—factors that’ll be critical in determining whether green hydrogen at Sasolburg can compete commercially. The study’s outcomes will ultimately determine whether these product pathways move from possibility to investment decision.

South Africa–China energy cooperation provides broader context

The choice of venue wasn’t incidental. Showcasing the Sasol-Envision collaboration at the South Africa-China Energy Investment Conference placed it within a broader frame of bilateral engagement on clean energy and industrial technology — a frame that added visibility neither party would have had from a quiet technical announcement.

Envision Energy describes itself as a global green technology company, with a portfolio spanning wind and solar energy, battery storage, and hydrogen infrastructure. Its Chifeng Hydrogen Net Zero Industrial Park in Inner Mongolia served as a live demonstration of what integrated green hydrogen systems can look like at scale, a relevant backdrop for a study aimed at replicating elements of that model in South Africa.

Kane Xu, Senior Vice President and President of International Product Line at Envision Energy, framed the partnership in expansive terms: “Green hydrogen will play a critical role in reshaping hard-to-abate industries and creating new pathways for sustainable growth.”

The collaboration also reflects a pattern becoming more visible—South African industrial companies engaging Chinese technology providers to access expertise relevant to decarbonization goals. Whether that trend deepens will depend partly on how studies like this one play out.

A green hydrogen design study

Here’s where things stand. Sasol has commissioned Envision Energy to conduct a green hydrogen design study at its Sasolburg facility, assessing the integration of renewables, battery storage, and electrolyzers. The design phase is expected to wrap up later in 2026.

Subject to study outcomes and investment decisions, the green hydrogen produced could feed into the manufacture of eMethanol and potentially eSAF—both growing markets for low-carbon fuels. The partnership was announced during the South Africa-China Energy Investment Conference, with South African Energy Minister Dr Kgosientsho Ramokgopa present at the showcase. The design study will deliver the technical and commercial data Sasol needs to decide on any next investment steps. No final investment decision has been made.
