Wilcox, Jennifer. 2020: “The Giving Earth.”

Wilcox, Jennifer. 2020: “The Giving Earth.” Spring Bridge Issue on Engineering and Climate Change (50/1).

"What if methods could be engineered to render fossil energy “green” by replacing the pore space in rocks depleted of oil and gas with sequestered CO2? This is possible, but it does not seem a fair trade to Earth."

Yu, Qian; Brilman, Wim (2020): A Radial Flow Contactor for Ambient Air CO2 Capture

Yu, Qian; Brilman, Wim (2020): A Radial Flow Contactor for Ambient Air CO2 Capture. In Applied Sciences 10 (3), p. 1080. DOI: 10.3390/app10031080.

"In this paper, the performance of a new radial flow reactor (RFR) for CO2 adsorption from ambient air is reported. The reactor uses a supported amine sorbent and is operated in a batch mode of operation or semi-continuously, respectively without or with sorbent circulation."
