The carbon capture chemicals market is projected to grow from $1.82 billion in 2025 to $2.12 billion in 2026, a 16% CAGR, and reach $3.79 billion by 2030. The chemicals involved include amine-based solvents, sodium hydroxide, ammonia, and calcium oxide, used across post-combustion capture, pre-combustion capture, oxy-fuel combustion, and direct air capture. Power plants and industrial processes remain the main demand sources. Recent activity includes SLB's $380 million majority acquisition of Aker Carbon Capture in March 2024, which pairs engineering services with capture chemistry. Direct air capture is also getting attention, with Saudi Aramco testing a DAC unit in March 2025. The report's key question is whether cost and energy use per ton of CO2 fall enough for these chemicals to scale beyond pilot projects.
