CEMEX, Sasol and ENERTRAG accomplice to show CO2 from cement plant into Sustainable Aviation Gas


Mexico-based world building supplies firm CEMEX is partnering with built-in chemical compounds and vitality firm Sasol ecoFT and renewable vitality firm ENERTRAG to mix CO2 with hydrogen to provide sustainable aviation gas. This undertaking is a part of CEMEX’s Future in Motion program to cut back its carbon footprint and contribute to a round financial system and an integral element of CEMEX’s grasp plan to develop a carbon impartial operation at its Rüdersdorf cement plant by 2030.

The consortium will supply inexperienced hydrogen generated solely from wind and photo voltaic vitality from ENERTRAG. The CO2 will come from CEMEX’s Rüdersdorf cement plant in Germany, which can present 100 tons of CO2 per day within the undertaking’s first section. Sasol ecoFT will then contribute its know-how to provide e-kerosene, which, as soon as licensed, will be blended to represent as much as 50% of jet gas.

On this first section, 15,000 tons of electrical kerosene are to be produced yearly, from the 100 tons of CO2 per day mixed with 12 tons of hydrogen per day.

Within the second section, bigger portions of hydrogen are to be provided by pipeline. The inexperienced hydrogen can be produced as a part of the ENERTRAG IPCEI undertaking “Electrolysis Hall East Germany” with an electrolysis capability of 210 MW, which can allow the manufacturing of 35,000 tons of e-kerosene gas per 12 months. Additionally on this undertaking, solely renewable electrical energy is used for the manufacturing of 40 tons of inexperienced hydrogen per day. This requires a rise in CO2 seize by one other 300 tons per day.

The three companions have based Concrete Chemical substances GmbH, which is to implement the pioneering undertaking on the CEMEX website in Rüdersdorf close to Berlin. All three firms are equal companions within the three way partnership. For the implementation of the undertaking, the consortium is making ready funding purposes to be notified at European stage.

Sixty p.c of the carbon emissions within the cement manufacturing course of come from the chemical response that happens in cement kilns. To succeed in carbon neutrality, these emissions have to be captured, saved, or repurposed not directly. CEMEX is main the way in which in these applied sciences by way of partnerships with different industries, the work of its R&D heart, and investments from its enterprise capital arm, CEMEX Ventures.

The Rüdersdorf carbon impartial alliance consists of greater than 20 startups, universities, firms from different industries, and authorities working to develop industrial-scale options utilizing modern applied sciences to realize the primary carbon-neutral cement plant on this planet.


ENERTRAG is a renewable-energy firm based mostly in Brandenburg, Germany. ENERTRAG develops, builds, owns, and operates utility-scale built-in vitality crops in ten nations globally. ENERTRAG’s crops produce dependable electrical energy and inexperienced hydrogen solely from wind and solar.

Sasol ecoFT is a part of the Sasol Group and world-leader within the growth and utility of Fischer-Tropsch (FT) know-how with greater than 70 years’ expertise. Sasol ecoFT leverages it proprietary know-how, know-how and experience to provide sustainable fuels and chemical compounds from inexperienced hydrogen and sustainable carbon sources by way of the Energy-to-Liquids (PtL) course of.
