HeidelbergCement has unveiled plans to build what is believed to be the world’s first carbon-neutral cement plant that hopes to capture up to 1.8million tonnes of carbon dioxide (CO2) annually from 2030 onwards.

Unveiling details of the project today, HeidelbergCement said the plant will be located on the Swedish island of Gotland at the Slite plant of HeidelbergCement’s subsidiary Cementa, with the carbon capture facility being located next to the existing plant.

Once captured, the CO2 will be transported to a permanent storage site offshore several kilometres down in bedrock.

In addition to incorporating carbon capture technology at the site, HeidelbergCement will also increase the use of biobased fuels in the cement production to significantly raise the share of biomass in the fuel mix.

Commenting on the major plans, Dr. Dominik von Achten, Chairman of the Managing Board of HeidelbergCement, said, “HeidelbergCement will be the leader in the global cement industry on its transformation path towards climate neutrality.”

“Key for decarbonising our industry is to find, apply and scale technical solutions for carbon capture and utilisation or storage. After having gained valuable experience with CCU/S technologies in Norway and other countries, we are now excited to make the next step with a completely carbon-neutral cement plant in Sweden. This will be a game changer for our industry.”

It is believed that the authorisation processes and the construction period are estimated to take just under ten years. A feasibility study, which has already been launched, will address critical issues related to technology selection, environmental impact, legal issues, financing, logistics, and energy supply.
