go4zero project

GO4ZERO will deploy an innovative air-oxyfuel switchable kiln with carbon purification technology at Holcim’s cement plant in Obourg, Belgium. CO2 will then be sequestered under the North Sea. The project aims to be operational by 2028 and store around 1.1 million tonnes of CO2 per year.

In 2023, the project was selected for a grant from the EU Innovation Fund.

Storage pathway

The technology behind the project

The project will be carried out in two phases. The first phase consists of replacing the current clinker kiln with a next-generation air-oxyfuel switchable kiln. This will enable a reduction in CO2 emissions of nearly 30% per tonne of clinker.
 

The second phase consists of capturing CO2 and implementing an innovative oxyfuel process using Air Liquide’s CryocapTM Oxy technology. The technology will purify CO2 generated from production in Obourg to above 99.5%. Captured CO2 will then be transported via Fluxys’ network to the Antwerp@C CO2 Export Hub where it will be liquified and shipped for storage under the North Sea.

“With GO4ZERO, we are developing a full carbon capture, transport and storage value chain with the goal to be producing net-zero cement by the end of the decade.”

More on Holcim's net-zero journey

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.

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

eCapt-Rhône: Creating the first CO2 capture facility at a white cement plant

The eCapt-Rhône project uses renewable hydrogen production and CO2 captured from Holcim’s cement plant in Le Teil to generate e-methanol.
