Carbon Clean Solutions Limited reaches biogas milestone in Germany


Carbon Clean Solutions Limited (CCSL), a carbon dioxide (CO₂) separation technology innovator, has surpassed 500,000 m3 of biogas processed per day with its Methpure solvent across Germany for the first time.

This is the daily equivalent of powering 9,817 cars from Berlin to Munich (580 km) on biomethane fuel.

This is a huge milestone for the company, which entered the biogas upgrading market in 2015 with its technology operational at just two plants. Since then, the company has grown its footprint and its Methpure solvent is now being used in 26 biogas upgrading plants across Germany. Methpure is now one of the most widely-used solvents in the EU for biogas upgrading plants to run their chemical scrubbers more efficiently.

CCSL’s drop-in solvent technology – ‘Methpure’ – enables CO₂ and other impurities to be removed from biogas through chemical scrubbing in a cheaper, more efficient way compared to other existing technologies. It is less reactive to oxygen (O2) and other contaminants, increasing solvent life and reducing corrosion. It also allows for a 30% reduction in energy consumption and pumping requirements over its lifetime when compared to the traditional solvent, MDEA. This results in reduced downtime and can also help biomethane producers to increase their operating capacity by as much as 25%, without any additional capital investment. By using CCSL’s solvent, biomethane producers have found they can recover their initial cost investment in the solvent within three to six months.
