eCapt-Rhône carbon capture project

The eCapt-Rhône project uses renewable hydrogen production and CO2 captured from Holcim’s cement plant in Le Teil to generate e-methanol. It is set to become the first large-scale plant in France to produce 138 kilotons (kt) of e-methanol per year. The project aims to replace about 20% of current French methanol consumption by providing locally produced e-methanol to industrial firms, thereby reducing CO2 emissions by 70%. 

The plant’s goal is to capture 100% of CO2 emitted – around 200,000 tons – annually, by 2028. In 2023, it received a grant from the EU Innovation Fund.

The technology behind the project

The eCapt-Rhône project is driven by three technological processes:

  • Carbon capture: a fully electric and chemical-free solution will be used. This involves both boosting oxygen levels in the kiln line and using end-of-pipe cryogenic carbon capture technology.
  • Hydrogen production: a 170 MW electrolyser powered by green energy will produce 27 kt/y of green hydrogen.
  • E-methanol production: a first-of-its-kind high capacity reactor will be able to provide 138 kt/y of methanol.

The capture brick will be located at Le Teil cement plant while the hydrogen and e-methanol production infrastructure will be installed at the Osiris chemical platform, located just 100 kilometers from the plant. Transportation will be managed by rail.

“The eCapt-Rhône project has an important role to play in the industry, both by making the large-scale capture of CO2 in a cement plant a reality and by producing e-methanol directly amidst industrial consumers.”

More on Holcim's net-zero journey

Go4ECOPlanet will install a unique facility to capture 100% of CO₂ emissions generated during the production of clinker – the key ingredient in cement production.

In Belgium, the GO4ZERO project will deploy an innovative carbon capture technology at our plant in Obourg, and transport CO2 for offshore storage under the North Sea.

The KOdeCO net zero project aims to make Holcim’s Koromačno plant the first to produce net-zero cement in Croatia and the Mediterranean.

OLYMPUS is a flagship project in Holcim’s European decarbonization roadmap. It will lead to the development of storage capacity in southern Europe.

The Carbon2Business project at our cement plant in Lägerdorf, Germany aims to capture more than 1.2 million tons of CO2 emissions annually.
