Bay Area startup CarbonVault has closed a $150 million Series C funding round to scale its direct air carbon capture technology. The company claims its modular capture units can remove CO2 from the atmosphere at less than $100 per ton, well below industry averages.
Investors include Breakthrough Energy Ventures, Sequoia Capital, and several sovereign wealth funds. CarbonVault plans to deploy 200 capture units across the western United States by the end of 2027.
The funding round is one of the largest ever for a carbon capture startup and signals growing investor confidence in the commercial viability of the technology.
