CarbonCapture uses a temperature-vacuum swing adsorption (TVSA) direct air capture process. In capture mode, a fan blows air over an amine-based sorbent. After CO₂ has adsorbed on the surface of the sorbent, a shutter closes at the front of the reactor and a vacuum is applied to remove residual air. Steam is then added to heat the sorbent to ~100 C, thereby releasing the CO₂. The resulting CO₂ stream is then ready for compression, transport, and storage.
CarbonCapture has built a modular and upgradeable capture system that allows them to swap in best-in-class sorbents as they become available. In parallel, they’re actively cultivating a pipeline of new sorbents through external partners.
Frontier buyers’ total offtake is $20.0M for 45,500 tons to be delivered as a blend across sorbent and hardware generations deployed from 2025-2028. The price accounts for both the removal itself as well as measuring, reporting and verifying (MRV) that each ton is safely and permanently stored. This agreement includes key milestones that must be met prior to delivery, including sharing a community benefits plan, presenting results from their FEED study, signing a PPA for renewable energy on their local grid, and securing permits for storage.
