CapCO2 · Intensified Process for CAPturing CO2

Today, around 35 Gtons/year of carbon dioxide are emitted worldwide from industrial plants in a large number of sectors such as coal-fired power stations, chemical refineries, waste-to-energy plants, cement production, iron plants, steel plants and off-shore platforms. Although the efforts of industry and public entities to support the development of efficient solutions able to capture CO2 and avoid its emission to the atmosphere, thus mitigating the greenhouse effect, currently the Carbon Capture technologies cost is unsustainable: the first Carbon Capture and Storage (CCS) projects cost > 70 € per tonne of carbon dioxide captured, a value higher than the European carbon tax (< 15 €/tons, expected to reach 45 €/tons in 2021), making the CCS economically inconvenient. Carbon Clean Solutions Ltd. has developed a CO2 capture process, called CapCO2 and characterized by two disruptive innovations: 1) the intensified CO2 capture solvent, called CDRMax, with a reduced water content and a higher stability in respect to the industry benchmark solvent MEA; 2) the CO2 absorber and solvent stripper configuration using Rotary Packed Bed (RPB) technology, which reduces the units size of a factor > 9. CapCO2 solution is able to drastically reduce the carbon capture cost up to 20 €/tons (60-78% lower than conventional solutions), making sustainable the installation of CO2 removal units in industrial sector. CCSL solvents are already active market products (applied in 25 anaerobic digestion plants in Germany for biogas upgrading) while the RPB technology has been validated by a first prototype. Now, CCSL aims to develop an integrated Mobile Intensified Compact CO2 (CO2 MIC) capture unit, with a capacity of 10 tons CO2 captured per day: the CapCO2 mobile unit will allow the validation of CapCO2 technology in different operating fields, being helpful for understanding and establishing detailed techno-economic evaluations at various industrial flue gas sources.
