Novel amine-based sorbents for carbon dioxide capture with enhanced oxidative and thermal stability
BACKGROUND:
Anthropogenic climate change presents an urgent threat to ecosystems, public health and economic stability. Even single degree increases in global temperatures can trigger irreversible impacts, ranging from biodiversity loss and food insecurity to more frequent extreme weather events and rising human mortality. This climate change is also creating atmospheric carbon dioxide accumulation that requires the generation of novel and scalable negative emissions technologies, such as direct air capture (DAC), to achieve the international net-zero emission goal by 2050.
TECHNOLOGY OVERVIEW:
Amine-based sorbents are among the most effective materials for DAC due to their high selectivity for carbon dioxide, but they are susceptible to chemical and thermal degradation in real-world deployment. Oxidative stress causes formation of heat-stable salts and toxic byproducts that lead to declining performance and premature sorbent failure. Sorbent degradation shortens performance efficiency, increasing the energy and cost penalties associated with frequent regeneration and replacement for commercial applications. This University at Buffalo technology presents innovative polyamines for DAC that enhance oxidative and thermal stability while preserving strong affinity and selectivity for carbon dioxide. In addition, its faster adsorption/desorption kinetics and low temperature regeneration properties make it suitable for a wider range of commercial applications.
