With the construction of another pilot plant for CO2 capture, Aalborg Portland, part of Cementir Holding Group, is starting a new collaboration that intends to push the development of CCUS (carbon capture utilization storage) further. The cement manufacturer states this in a press release.
The collaboration, called ConsenCUS, has a number of leading research institutions and innovative companies on board, and together the association aims to develop a new technology within CO2 capture that can potentially significantly reduce energy consumption for CO2 capture and ensure a more efficient utilization of the collected CO2.
- With the commissioning of the next pilot plant for CO2 capture at the factory in Aalborg, we can look forward to gaining even more experience with CO2 capture from cement production. Since December 2022, we have been conducting a pilot project in collaboration with researchers from DTU, who are among the world leaders in CO2 capture, and we have thus been confirmed that capture from our production is possible and that the potential is significant. Now we are building another pilot plant, where we are testing a new technology for CCUS, and we hope to learn even more about our options within CO2 capture, says CEO Søren Holm Christensen from Aalborg Portland.
Can save energy and convert the captured CO2 into formic acid
The most widely used technology for CO2 capture today requires high temperatures as part of the process, and this results in high energy consumption. The purpose of the construction of the new CO2 capture plant at Aalborg Portland is therefore to test a new technology that can potentially eliminate large parts of the energy consumption by using an electrochemical method powered by electricity rather than the otherwise necessary high temperatures. The method, which only uses electrical energy, can potentially halve the energy consumption compared to traditional capture methods.
- One of the challenges of CO2 capture is that it requires large amounts of energy to operate the process. With this plant, we can potentially eliminate large parts of the energy consumption by using a new technology. At the same time, the plant can create a directly usable product on site, which can also streamline some of the processes in connection with CO2 capture. We will therefore follow the results and experiences with this CCUS plant incredibly closely, as it definitely has some interesting perspectives, says Søren Holm Christensen.
The ConsenCUS plant will replace the current CO2 capture plant, which was built in collaboration with, among others, DTU with support from the Innovation Fund Denmark. Aalborg Portland will thus be the first place where the new CO2 capture plant and the associated technology from the ConsenCUS collaboration will be tested on a larger scale.
The new plant can capture up to 2.4 tons of CO2 per day. It is scheduled to be commissioned in November, where it will be tested at Aalborg Portland until March 2024.
