CO2 Capture Processes

Carbon Clean provides services needed to achieve net zero, including technology licence and solvent supply, a full process design package (PDP) and proprietary equipment, and end-to-end systems — including design, build, financing and operation.”

“Our next-generation modular technology is currently being tested for a full product roll-out. It brings full modularisation and containerisation to both industrial carbon capture and biomethane facilities. This technology will deliver a 10x reduction in equipment size, resulting in a 50% reduction in both capex and opex compared to traditional open-plant designs. We are currently targeting a $30/tonne cost of capture, as the technology matures. This is a massive reduction from the typical current cost of capture of $70/tonne — making decarbonisation much more affordable and accessible to facilities of all kinds.”

“C-Capture has patented a unique, solvent-based technology which offers a safe, low-cost way to remove carbon dioxide from emissions using a post-combustion capture approach. C-Capture was founded in 2009 as a spin-out from the Department of Chemistry at the University of Leeds, and recent investors include IP Group, Drax, and BP Ventures.”   

“The core technology element is the CO₂ collector, which selectively capture CO2 in a two-step process. Carbon dioxide is captured on the surface of a highly selective filter material inside the collectors. Once the filter material is full with CO2, the collector is closed and the temperature increased to between 80 and 100 °C releasing high-purity CO2.”

GT offers a platform of technologies for different uses: i) a pure air embodiment, which is claimed “can be carbon negative“; ii) a ‘carbureted’ embodiment co-located with industrial facilities to utilize their residual heat, and capture concentrated CO₂ from those facilities’ exhausts, bending the CO₂ with atmospheric air to capture significantly more CO₂ than is being emitted, and by doing so “can be carbon negative.” “This model produces the lowest cost CO₂ per tonne.“; iii)  a self carbureted solution which is stand-alone, “burning fuel in gas turbines to generate the heat and electricity needed to capture their own emissions while also capturing CO₂ from the atmosphere, remaining carbon negative.”
