London-based carbon dioxide capture and separation technology solutions provider Carbon Clean has secured an additional $8 million in funding. The capital is an extension of a $22 million Series B round. Since its inception in 2009, Carbon Clean has raised a total of $64.4 million. Focusing primarily on carbon-producing heavy industries such as cement, iron and steel, refineries, and energy from waste, Carbon Clean’s patented technology claims to be more cost and environmentally effective when compared to existing techniques. Carbon Clean's solutions have been proven at locations in the UK, the US, Germany, India, Norway, and the Netherlands, and is currently in use at the world’s largest industrial-scale carbon capture and utilisation plant in Tuticorin, India. Carbon Clean has seen previous support from the UK Government in 2012, 2016 and 2018, and has been awarded a ‘Technology Pioneer’ award by the World Economic Forum. The $8 million Series B extension arrives via building materials maker CEMEX. Existing investors include Equinor Ventures, ICOS Capital, and WAVE Equity Partners.
