Whilst research for carbon capture and its storage has been conducted for 4 decades, the need to refine the technology and make it as energy efficient possible is required. This is scenario now as carbon capture and its storage has an important element in the climate program of the Danish government. As per estimates of the program, carbon capture has the potential to lessen CO2 emissions from 4- 9 million tons by 2030.
In fact, at the Technical University of Denmark, researchers have been for some time been researching and investigating how to capture CO2 from flue gas from biogas plants or CHP plants instead of only discharging it. In fact, the most widely used methods is to capture CO2 from flue gas channel into a liquid.
At present, researchers at DTU are ready to test a new and more energy-efficient method that can capture CO2 in a solid material and upgrade it to a cleaner product. This can be subsequently used to produce fuels for example.
Meanwhile, research has been conducted for several years that is aimed at finding an environment-friendly material that CO2 can attach with. However, the material is in solid form and where the captured CO2 can be upgraded using significantly less energy.
The testing of the technology is scheduled for Sweden in 2021 along with Wartsila, the latter supplies sustainable technologies to the manufacturing sector, stated the head of the project.
The actual installation and testing of the carbon capture unit equipped with the new technology will be demonstrated at one of the projects of Wartsila biogas plant. The demonstration will involve purifying part of the biogas produced.
