Short answer from the current literature: probably not at the scale required, under current cost trajectories, without policy support that does not yet exist in any major economy. But "probably not" is not the same as "no," and the detailed picture matters. Direct air capture, enhanced weathering, and BECCS each have different cost curves, energy requirements, land-use implications, and deployment timelines. This review would assess whether any credible combination of technologies could reach gigaton-scale removal by 2055 under a range of policy scenarios - not to offer false hope, but to identify where research investment would have the highest expected return.
The BECCS land-use numbers in the IPCC pathways are what concern me most — the area required is multiple times the size of India. That's not a realistic deployment scenario under any plausible policy environment.
The cost curve for direct air capture has improved significantly in the last five years but it's still orders of magnitude too expensive for gigaton-scale deployment without massive subsidy. The enhanced weathering angle is underreported — lower cost ceiling but enormous land-use and monitoring challenges.
