Carbon Clean Headquarters: United Kingdom. Established 2009. Offices: India, Spain, USA

Carbon Clean says that by 2020 the company has removed 800,000+ tonnes of carbon from 38 facilities across the globe. “Our work is founded on the belief that achieving net zero isn’t a pipe dream, it’s an imperative. But it will take far more than a focus on renewables. Key industries can and should play a significant role in global carbon reduction. More...

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.”

“The 3C technology has capture capability on a global, megatonne scale. By modular scalability, we can provide CO2 capture in the range of 10.000 tonne per year in Demo scale sizes, up to more than a million tonne per year by combining several Industrial units. More...

The equipment can handle CO2 concentrations in the flue gas from below 4% to above 50%, and deliver very pure CO2 at overpressure directly from our plant – to save energy in compression.” The video claims a 75% plant size reduction.”   “The 3C technology is invented in a collaboration with Fjell Technology Group AS, Equinor ASA, CMR Prototech AS and SINTEF Tel-Tek. The development project was initiated by Equinor back in 2007, but the first patent for the technology (by Prof. Dag Eimer) was granted already in 1999.”

The claim is a new solvent that reduces energy requirement by ‘upto’ 90% compared to conventional technology (presumably amine based systems). Being tested at the DRAX bioenergy plant.  More...

“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.”   

Climeworks  Headquarters, Switzerland.

“Climeworks develops, builds and operates direct air capture machines. The carbon dioxide can either be used as a raw material, or completely removed from the air by safely storing it. More...

Our machines consist of modular CO₂ collectors that can be stacked to build machines of any size. Climeworks direct air capture machines are powered solely by renewable energy or energy-from-waste. Grey emissions are below 10%, which means that out of 100 tons of carbon dioxide captured, at least 90 tons are permanently removed.”

“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.”

Direct Air Capture removes carbon dioxide directly from the air with a mechanical system. The Carbon Engineering’s system “does this by pulling in atmospheric air, then through a series of chemical reactions, extracts the carbon dioxide (CO2) from it while returning the rest of the air to the environment.”

A Direct Air Capture process. “… that it works equally well at capturing CO2 from power plants and industrial flues as it does capturing CO2 directly from the air anywhere.”   “GT can also economically extract CO2 directly from the air, making it affordable, reliable, and abundantly available for use practically anywhere.More...

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.”

Aker Carbon Capture  Headquarters, Norway

“Aker Carbon Capture is a leading carbon capture technology provider.” Aker says that it has developed best-in-class technologies, including a proprietary carbon capture (organic amine) solvent. Aker has 20+ years of experience developing carbon capture technologies, delivering front-end design and testing large-scale carbon capture plants at industrial sites.

Are there other novel capture processes we missed?
