Envision Energy, a green technology company headquartered in China, has announced a collaboration with South African energy and chemicals company Sasol to advance a design study for a potential green hydrogen system at Sasol's Sasolburg operations in South Africa.

The announcement represents what both companies describe as an important step in exploring how renewable power, energy storage, and electrolyser technologies could be integrated to produce green hydrogen at an industrial scale.

What the Collaboration Involves

The design study will evaluate how renewable power generation, energy storage systems, and electrolyser technologies can be integrated and optimised based on energy availability, market conditions, and operational requirements.

Envision will bring its capabilities in renewable energy, battery energy storage systems, green hydrogen production, and AI-enabled energy management to the collaboration.

Among the potential downstream applications identified in the announcement are eMethanol and sustainable aviation fuel, known as eSAF. Both are categorized as lower-carbon fuels and chemicals that could be produced using green hydrogen as a feedstock, though neither is described as a confirmed output at this stage.

Sasol stated it is evaluating opportunities to leverage its existing industrial capabilities and infrastructure at Sasolburg while exploring technologies to support its energy transition pathway and future market opportunities.

The design study is expected to be completed later in 2026 and is intended to provide technical and commercial insights to support potential future investment decisions.

Announcement Made During South Africa-China Energy Conference

The collaboration was announced during a visit by South Africa's Minister of Electricity and Energy, Dr. Kgosientsho Ramokgopa, to Envision's Chifeng Hydrogen Net Zero Industrial Park, located in Inner Mongolia, China.

The visit was made as part of the South Africa-China Energy Investment Conference, providing a diplomatic and bilateral trade backdrop to the announcement.

The Chifeng facility serves as a demonstration site for the kind of integrated hydrogen production infrastructure that Envision is proposing to study in the context of Sasolburg. No further details about the Minister's visit or any policy commitments arising from the conference were provided in the announcement.

Perspectives from Both Companies

Kane Xu, Senior Vice President and President of International Product Line at Envision Energy, framed the collaboration in the context of the company's broader mission.

"Green hydrogen will play a critical role in reshaping hard-to-abate industries and creating new pathways for sustainable growth. Through AI-powered energy infrastructure and innovative technologies across renewables, storage, and green hydrogen, Envision is working with global partners like Sasol to pioneer future energy systems that are infinite, intelligent, and inexpensive, accelerating industrial transformation and creating new opportunities for industries and communities worldwide," Xu said.

Danie Cronje, Sasol's Senior Vice President for Business Building, described the design study as a means of drawing on global expertise to assess cost-competitiveness.

"The design study with Envision is an important step in assessing how integrated renewables, energy storage and electrolyser technologies could support cost-competitive green hydrogen production at Sasolburg. 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," Cronje said.

Sasol's Sasolburg Site as a Starting Point

Sasolburg, located in the Free State province of South Africa, is one of Sasol's established industrial operations. The choice of Sasolburg for this design study reflects Sasol's stated intention to build on infrastructure and capabilities it already has in place rather than developing a greenfield site. The company has not disclosed specific details about the size or configuration of the hydrogen system under consideration at this stage of the study.

Sasol describes itself as a global energy and chemicals company, and the design study represents one element of what the company characterized as its broader energy transition pathway. The announcement did not provide a timeline for any final investment decision or construction activity beyond the completion of the design study itself.

Envision's Role in the Global Hydrogen Sector

Envision Energy describes itself as a global leader in green technology and has positioned itself as a developer of integrated energy systems that combine wind and solar power generation, battery storage, and hydrogen production under a single AI-driven management framework. The company's Chifeng Hydrogen Net Zero Industrial Park in Inner Mongolia is presented as a working example of this integrated model.

The Sasolburg design study would mark an extension of Envision's approach into the African market. The company has framed its international partnerships as part of a strategy to accelerate industrial decarbonisation in sectors where direct electrification is difficult, commonly referred to as hard-to-abate industries.

The announcement did not specify the financial terms of the collaboration, nor did it indicate which party would bear the costs of the design study.
