Yu, Q. (2018): Direct capture of CO2 from ambient air using solid sorbents

Yu, Q. (2018): Direct capture of CO2 from ambient air using solid sorbents. Enschede: University of Twente. DOI:10.3990/1.9789036546300

"In this thesis, a novel process is developed and experimentally demonstrated, for CO2 capture from ambient air to produce CO2 enriched air to enhance microalgae cultivation. First, an amine functionalized sorbent is selected, initially based on its water and CO2 equilibrium adsorption capacity. Subsequently, the selected sorbent is characterized on its stability under different conditions for a wide range."

Climate Science, Awareness and Solutions Blog: Get Out of Jail Free Card: Carbon Capture

"I am minimizing Communications, so that I can (really!) finish Sophie’s Planet, while also providing expert testimony for several lawsuits aimed at using the judicial branch of government to force the other branches of government to do their job.  However, there is enough popular misinterpretation of recent news about the cost of carbon capture that I should comment on that."

Keith, David W.; et al. (2018): A Process for Capturing CO 2 from the Atmosphere

Keith, David W.; Holmes, Geoffrey; St. Angelo, David; Heidel, Kenton (2018): A Process for Capturing CO 2 from the Atmosphere. In Joule. DOI: 10.1016/j.joule.2018.05.006.

"We describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. We describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm."

ecoRI News: Time to Start Using the Climate Tools We Have

"Too much carbon dioxide in the atmosphere is the primary cause of climate change. To stop climate change, we need to stop adding CO2 to the atmosphere and start taking it out. With renewable energy and direct-air CO2 capture, we can do both, and we can do them in ways that save money."

Daily Energy Insider: EPW Committee highlights support for carbon utilization, direct air capture research bill

"The Senate Environment and Public Works (EPW) Committee recently highlighted support from various stakeholders for the Utilizing Significant Emissions with Innovative Technologies (USE IT) Act, which would support carbon utilization and direct air capture research. The legislation would also support federal, state and non-governmental collaboration on the construction and development of carbon capture, utilization, and sequestration (CCUS) facilities and carbon dioxide (CO2) pipelines."

Song, Juzheng; et al. (2018): Quaternized Chitosan/PVA Aerogels for Reversible CO 2 Capture from Ambient Air

Song, Juzheng; Liu, Jie; Zhao, Wei; Chen, Yan; Xiao, Hang; Shi, Xiaoyang et al. (2018): Quaternized Chitosan/PVA Aerogels for Reversible CO 2 Capture from Ambient Air. In Ind. Eng. Chem. Res. DOI: 10.1021/acs.iecr.8b00064.

"Developing inexpensive and highly efficient CO2 air capture technologies is an important solution for solving the greenhouse problem. In this work, we used the low-cost quaternized chitosan (QCS)/poly(vinyl alcohol) (PVA) hybrid aerogels with quaternary ammonium groups and hydroxide ions to reversibly capture CO2 from ambient air by humidity swing."

Bellona: EU Parliament concludes synthetic low carbon fuels should indeed be low carbon

"Yesterday, the European Parliament voted on the use of renewable energy in the coming decade. Of all the big issues on the radar, the Parliament caught the one that tried to fly under it – synthetic fossil fuels. Produced by using massive amounts of renewable energy and fossil CO2 from industrial sources, the fuel would be emitting that same fossil CO2 back to the atmosphere from the tailpipe of the car it’s combusted in. By requiring the use of CO2 captured from the ambient air for its production, the Parliament ensured that the so called synthetic low carbon fuel indeed remains low carbon. However, much remains wanting in the renewable energy directive, but in this regard the Parliament move prevents CO2 laundering and false climate accounting of new synthetic fossil fuels."
