The Real-World Progress and Economic Hurdles of Carbon Capture Technology

The gap between ambition and deployment in carbon capture has never been more quantifiable. Operating commercial CCS projects captured roughly 64 million tonnes of CO₂ in 2025, per a Forbes analysis, while steel, cement, and chemicals alone emit about 6 billion tonnes annually—roughly 70% of direct industrial emissions. That ratio, more than any speech at COP, defines the current state of CCUS.

What's actually moving

The International Energy Agency's 2026 project update counted double-digit progress in two metrics that matter. Operational and under-construction capture capacity grew by more than 10% year-over-year; storage capacity expanded by roughly 25%. Total potential capture capacity still hovers near 425 million tonnes per year, but the trajectory is upward. The IEA catalogued 27 commissioned direct air capture (DAC) plants, and U.S. regional DAC hubs are each engineered to demonstrate at least 1 million tonnes of annual capture. Pre-combustion capture is yielding hydrogen-rich fuels for downstream use. Post-combustion systems—solvent-based, retrofittable to existing exhaust stacks—are the workhorses most likely to scale inside cement, steel, and chemical facilities without requiring greenfield builds.

Where the bottlenecks compound

Cost remains the binding constraint. DAC currently runs $800–$1,900 per tonne of CO₂ captured, a price band that yields negative margins under any carbon market below roughly $200/tonne. The timeline is also slipping: many announced projects have been pushed toward 2035, and the UNEP Emissions Gap Report 2025 projects 2.8°C of warming under current policies—2.5°C even with full implementation of national pledges. Existing power and industrial assets could still emit about 8 billion tonnes of CO₂ in 2050 unless they close, switch fuels, or install CCUS. Solvent regeneration in post-combustion systems demands additional energy, oxy-fuel combustion requires near-pure oxygen streams, and chemical looping depends on metal-oxide cycles that have yet to prove long-duration stability.

What to track next

Two near-term signals will indicate whether the IEA's 10–25% capacity growth translates into industrial-scale deployment. First, results from the non-amine carbon capture system trial reported by Enlit World—non-amine solvents and solid sorbents are the leading candidates to cut the energy penalty that currently limits retrofit economics. Second, the cost-curve trajectory for DAC, which Enlit's trial and hub-level procurement decisions will pressure-test through 2027. If non-amine chemistries yield even a 20% reduction in regeneration energy, the $800–$1,900/tonne floor becomes negotiable. The arithmetic is unforgiving, but the variables are now measurable—and that is precisely where progress compounds.
