Sustainable carbon cycle
Advanced electrochemical methods to capture renewable CO2 and recover energy from flue gas
Interest in Carbon Capture and Utilization (CCU) has been growing recently, i.e. the development of technologies to remove CO2 from flue gas and from the atmosphere, and use the captured CO2 as a working fluid, or as a source of carbon.
The development of such technologies should be based on sustainability criteria, i.e. creating low-energy solutions that will benefit the environment, the society, and the economy. To reach this target, further research is needed to develop novel CCU technologies.
At Wetsus, the Sustainable carbon cycle (SCC) theme aims to develop energy-efficient technologies to capture CO2 from the atmosphere and from renewable sources, and convert the captured CO2 into valuable chemicals. Our research focuses on electrochemical methods based on new electrode materials, ion exchange membranes, and new reactor design. The SCC theme builds on the long research experience at Wetsus in the field of applied electrochemistry for salinity gradients, capacitive deionization, and energy recovery.
Together with industrial and academic partners, our final goal is to boost the sustainable development of carbon capture and conversion, by combining clean electrochemistry, low-cost capture technologies, and production of chemicals.
