Wilson, Sean M. Wynn, and F. Handan Tezel (2020): Direct Dry Air Capture of CO2 Using VTSA with Faujasite Zeolites

Wilson, Sean M. Wynn, and F. Handan Tezel (2020): Direct Dry Air Capture of CO2 Using VTSA with Faujasite Zeolites. Industrial & Engineering Chemistry Research. https://pubs.acs.org/doi/abs/10.1021/acs.iecr.9b04803.

‌"In the process studied, a basic four step TVSA cycle comprising the following steps: pressurization with feed, adsorption, blowdown, and desorption was investigated first. Four different regeneration temperatures were tested along with four different gas space velocities."

Sen, Raktim, et al. (2020): Hydroxide Based Integrated CO2 Capture from Air and Conversion to Methanol

Sen, Raktim, Alain Goeppert, Sayan Kar, and G.K. Surya Prakash (2020): Hydroxide Based Integrated CO2 Capture from Air and Conversion to Methanol. Journal of the American Chemical Society. https://pubs.acs.org/doi/abs/10.1021/jacs.9b12711.

‌"We postulate that the high capture efficiency and stability of hydroxide bases make them superior to existing amine-based routes for direct air capture and conversion to methanol in a scalable process."

Butnar, Isabela, et al. (2020): The Role of Bioenergy for Global Deep Decarbonization: CO 2 Removal or Low‐carbon Energy?

Butnar, Isabela, Oliver Broad, Baltazar Solano Rodriguez, and Paul E. Dodds (2020): The Role of Bioenergy for Global Deep Decarbonization: CO2 Removal or Low‐carbon Energy? GCB Bioenergy, January. https://doi.org/10.1111/gcbb.12666.

"‌We use a global integrated assessment model, TIAM‐UCL, to investigate the role of bioenergy within the global energy system when direct air capture and afforestation are available as cost‐competitive alternatives to BECCS. We find that the presence of other CO2 removal technologies does not reduce the pressure on biomass resources but changes the use of bioenergy for climate mitigation."
