Additionally, novel solid adsorbents, such as metal-organic frameworks and porous carbon materials, are being researched for their ability to capture CO2 from flue gas. Companies in the field are focusing on developing novel reactor designs, improved heat integration, and optimization of operating parameters to minimize energy consumption and maximize carbon capture rates. The increasing advancements in post-combustion carbon capture & storage technology will present ample growth opportunities to the industry. Post Combustion Carbon Capture & Storage Market is expected to cross a valuation of USD 26.6 billion by 2032, according to the latest research report by Global Market Insights Inc. Aker Carbon Capture has subsequently re-filed several of these older patents under its own name.Ĭontroversies to explore with the company include future patent expiries, novelty (as other companies’ patents have discussed similar amine blends, albeit not as specifically), energy intensities (which could not be fully de-risked from the patents that crossed our screen) and focus (several patents discuss different solutions and even different sub-industries).įurther details into Aker Carbon Capture technology are set out in the data-file, and in our broader CCS research.Selbyville, Delaware, J(GLOBE NEWSWIRE). The most important challenges tackled in Aker Clean Carbon’s patents are around the balance of plant, avoiding release of amines and amine degradation components, especially as past designs for water wash units have been erratic. We think the most important amine patents are in Advanced Carbon Capture’s patent library. So the overall patent library contains filings from at least three separate companies. Reaction kinetics, in turn, are enhanced by blending this core amine with faster-reacting amines (chart below).Ĭomplexity? Aker Carbon Capture AS was formed from the 2014 merger of Advanced Carbon Capture AS and Aker Clean Carbon AS. This amine has a relatively less exothermic reaction with CO2 versus other amines, which means low regeneration energy, but also slow reaction kinetics. How does Aker Carbon Capture’s technology work? We think the high solvent stability mainly comes from steric hindrance around a primary amine at the core of the process. ![]() Our patent review also helps us to de-risk Aker Carbon Capture’s claims of high stability and low nitrosamine formation. We think we can guess the underlying components of S26 from this patent screen, and our guesses are spelled out in the data-file. What is Aker Carbon Capture’s specific technology and solvent cocktail? Several technical papers refer to a blend named “S26”. Based on our patent review, we think there is a moat around its technology. To address these challenges, Aker Carbon Capture states that its technology is derived from Northern Europe’s “largest R&D program” into amines, which tested 90 different solvent cocktails over 8-years, including 60,000 hours of operational testing of a front-runner solution. Amines used to capture CO2need to (a) react quickly with CO2 to form carbamates (aka “fast reaction kinetics”) otherwise the plant is overly large and the process is not feasible at scale (b) have low energy penalties when steam-treating amines so that their CO2 can be re-released for disposal ( TSE note here and data-file here) (c) be chemically stable, including low degradation rates ( TSE note here) (d) low emissions to air, including for ammonia, amines, but especially for toxic/carcinogenic breakdown products, such as nitrosamines, which ideally will not be generated at all and (e) have low corrosiveness. ![]()
