Exponential Temperature Sensitivity in CO₂ Capture and Release Systems

This paper examines carbon dioxide capture technologies through a minimal kinetic lens, focusing on the role of operating temperature in governing adsorption, regeneration, and lifecycle performance. Synthesizing results from amine scrubbing, solid sorbents, and direct air capture systems, it shows that CO₂ capture efficiency and energy cost exhibit exponential sensitivity to temperature arising from Arrhenius-controlled kinetics.

Rather than proposing new materials or capture architectures, the work reframes temperature as a high-leverage design parameter shaping feasibility across approaches. This perspective provides a physics-grounded framework for evaluating capture claims and for identifying system designs in which modest thermal optimization can yield disproportionate gains in efficiency, durability, and long-term viability under realistic operating conditions.
