Direct air capture companies | Trends, Share & Forecast 2025–2031

Direct air capture companies

This growth is mainly fueled by tightening global net‑zero mandates, steep scaling of DAC hubs backed by the U.S. Bipartisan Infrastructure Law and Inflation Reduction Act, and landmark investments from energy majors and tech giants aiming to offset emissions.

Key drivers include strong policy frameworks, rapid technological advances in sorbent and modular plant engineering, and rising corporate procurement of captured CO2 for sustainable fuel production and greenhouse enrichment. Geographically, North America leads on deployment. However, Europe complemented by significant Asia‑Pacific interest which results in the fastest expansion through 2031.
