Episode 3 of the XPRIZE Carbon Removal docuseries explores effective solutions that are pulling carbon dioxide directly from the atmosphere.
Meet the finalists pioneering these high quality solutions:
- Airhive: Airhive’s DAC technology employs fluidized-bed reactors to provide rapid CO2 removal via their low-cost, non-toxic metal-oxide-based sorbent.
- Heirloom + CarbonCure: Heirloom uses limestone in a cyclic process to capture CO2 directly from the air. Heirloom’s technology accelerates a natural weathering process, reducing the time it takes to absorb CO2 from years to less than three days. Heirloom works with CarbonCure to inject and mineralize the CO2 captured at their demonstration site into concrete.
- Octavia and Cella: Octavia designs, builds, and deploys highly modular machines that capture CO2 directly from the atmosphere using DAC technology. Cella, a CO2 storage provider, is developing in-situ mineralization technology for permanent carbon removal.
- Project Hajar (44.01 + Aircapture): Aircapture is deploying its state-of-the-art modular DAC technology on 44.01’s site. Here, 44.01 takes the captured CO2 and turns it into rock underground, using its pioneering technology that accelerates the natural process of CO2 mineralization.
- Skyrenu: Skyrenu combines an efficient and low-cost DAC system with a rock carbonation process to treat mine tailings in order to lock away carbon forever.
These teams are advancing direct air capture (DAC) and sequestration technologies that harness the power of mineral and chemical sorbents to pull CO2 from the air to store it permanently in minerals and deep underground. Learn more in this episode of our XPRIZE Carbon Removal docuseries.
