Carbon – Cycle Economy Demonstration (C-CED) is a flagship project in which a sustainable and closed carbon cycle is being established by combining and demonstrating different CO2 capture and utilization technologies. In the project, CO2 from various sources is captured on a pilot scale and converted into valuable renewable methane (methanation).
Methane as a carbon-containing energy carrier, but also as a raw material, plays an important role in many industrial processes. From today’s point of view, a complete abandonment is hardly conceivable, even though CO2 is often produced in these processes. Gaseous energy carriers, characterized by a high energy density and by the existing infrastructure, stand out as an excellent energy storage medium. At the same time, there are also industrial processes, where CO2 does not originate from fuels and CO2 emissions are unavoidable. Based on these considerations, it seems reasonable to establish a carbon cycle economy with seasonal large-volume storage facilities that provide the flexibility we urgently need for the switch to a renewable energy system.
