Enertrag, Sasol, Cemex team up to decarbonise cement, aviation industries

German renewables developer Enertrag SE, Mexican building materials maker Cemex (NYSE:CX) and a unit of South African chemicals company Sasol (JSE:SOL) will jointly work to produce sustainable aviation fuel (SAF) using carbon dioxide from cement production and green hydrogen.

The project will take place at Cemex's factory in Ruedersdorf near Berlin where carbon dioxide will be captured during cement production. The greenhouse gas will be then mixed with green hydrogen produced by Enertrag from regional wind and solar plants into synthesis gas. With the help of a technology developed by Sasol's ecoFT unit, the synthesis gas will be converted into longer chain hydrocarbons for the production of e-kerosene or SAF.

In the initial phase, 15,000 tonnes of e-kerosene will be produced annually using 100 tonnes of carbon dioxide and 12 tonnes of green hydrogen per day.

Enertrag will produce the green hydrogen as part of the Electrolysis Corridor East Germany project with an electrolysis capacity of 210 MW which will be enough to produce 35,000 tonnes of e-kerosene fuel annually.

The project will be implemented by Concrete Chemicals GmbH, an equally-owned joint venture that was established by the three partners in the initiative. The consortium is planning to apply for funding to finance the project.
