Carbon Capture and Utilization

Air Capture

Capture using liquid-like Nanoparticle Organic Hybrid Materials (NOHMS)


Air Capture

With the advent of carbon dioxide capture and storage (CCS) as a means of managing climate change, technologies for separating dilute carbon dioxide (CO2) from various gas streams are rapidly gaining importance.  Capture from very dilute streams would be of great importance, but unfortunately, most separation technologies are grossly energy inefficient.  At the LCSE we propose to revolutionize CO2 capture technology by extending the range of applications for a recently developed moisture swing sorbent in the context of capturing CO2 from air.  Moisture swing absorption has shown to have much greater efficiency for separating dilute carbon dioxide from various gas streams than conventional separation technologies, and it has the potential for a wide range of applications, including the capture of carbon dioxide from the atmosphere.

We have recently demonstrated this moisture swing sorbent cycle in the context of capturing carbon dioxide (CO2) from air.   The sorbent, an anionic exchange resin, has been shown to absorb CO2 when it is dry, and to release it again when exposed to moisture.  In ambient air, the resin will dry again. After drying it is ready for another absorption cycle.

The air capture team at the Lenfest Center has progressed with the addition of Senior Staff Associate Allen Wright.  Allen will be working with Tao Wang to quantitatively analyze the performance of the Air Capture media with the goal of understanding the mechanics, performance and environmental limitations of the current system.  Lab development will allow the work to proceed in a more analytical, efficient and productive manner.  Future work will cover the development of more effective media materials and geometries, along with the development of technologies to permit cost-effective operation of air capture systems.
