Can carbon capture startup Carbon Clean deliver on its cost claims? – TechCrunch

Start CarbonClean announced Earlier this week that it raised $150 million in a Series C that gives it a sizeable war chest to continue developing its modular carbon capture system.

Carbon Clean has garnered its share of admirers, most recently Chevron leading the round and BloombergNEF leading the way called It was a BNEF pioneer last month, in part because of the startup’s small-scale approach to carbon capture and sequestration (CCS).

Typically, the technology is a large-scale affair. After all, the world needs to eliminate emissions at scale, and the technology benefits from some scale. For this reason, CCS is usually connected to large coal or gas power plants.

But there are still many smaller sites, from cement kilns to chemical plants, that are currently locked into fossil fuels but have yet to be decarbonized. These are the types of companies Carbon Clean is taking on, and the startup says its modular approach can help polluters gradually deal with their carbon emissions as regulations tighten.

Basically, Carbon Clean relies on a tried and tested process to remove carbon dioxide from exhaust streams. Exhaust gas containing carbon dioxide is passed through a filter wetted with an amine-based solvent. At lower temperatures (about 50 degrees Celsius or 122 degrees Fahrenheit), carbon dioxide binds to the amines. The CO2-loaded solvent is then pumped to another container where it is heated to 110 to 120 degrees C (230 to 248 degrees F) to release the gas, which is then compressed and sent elsewhere for use or storage. Each company has its own amine solvent with different properties, and the details of the process may vary, but that’s the gist.

Aniruddha Sharma, CEO of Carbon Clean, said his company’s amine solvents can reduce costs compared to a commonly used amine by requiring less energy to heat and reducing corrosion in the system. Until the company releases more data, such claims will be difficult to judge. But based on that general type of amine usedCarbon Clean is likely to be seen at least a small improvement in energy consumption.
