Our Decarbonization Project for Holcim Cement Production Facility in Obourg, Belgium

Decarbonization project by Holcim and Totalenergies

Infographic describing the transformation cycle project of the Obourg cement plant conducted jointly by Holcim and TotalEnergies to make it a completely carbon-free site.

To achieve this, Holcim will be responsible for capturing and purifying the CO₂ from the cement plant using an air-oxyfuel switchable kiln. Once the CO₂ has been captured, there are two possibilities:

• TotalEnergies will take care of transporting the CO₂ to a new electrolyser. This infrastructure will enable the CO₂ from the cement plant to be converted into green hydrogen.
• The CO₂ is transported and stored by TotalEnergies in a CO₂ storage hub and then in a geological CO₂ storage area in the North Sea.

In addition to producing e-fuel, the electrolyser will also be used to power the cement plant’s air-oxyfuel switchable kiln.

Finally, a new renewable electricity production capacity in the North Sea will supply the cement plant and the new electrolyser with renewable electricity, contributing to the decarbonization of the Olbourg site.
