Cognitive Medium: Blog post by Michael Nielsen: The impact of direct air carbon capture on climate change

"In these notes I explore one set of ideas for helping address climate change: direct air capture (DAC) of carbon dioxide – basically, using clever chemical reactions to pull CO2 out of the atmosphere, so it can be stored or re-used."

Grist: Cement has a carbon problem. Here are some concrete solutions.

"The good news is that there’s no shortage of ideas for how to slim down cement’s weighty carbon footprint. The bad news is that most of them are either in their infancy or face significant barriers to adoption."

Beuttler, Christoph, et al. (2019): “The Role of Direct Air Capture in Mitigation of Anthropogenic Greenhouse Gas Emissions.”

Beuttler, Christoph, Jan Wurzbacher, and Louise Charles. 2019. “The Role of Direct Air Capture in Mitigation of Anthropogenic Greenhouse Gas Emissions.” Frontiers in Climate 1. https://doi.org/10.3389/fclim.2019.00010.

"The paper will give a brief insight into DAC and in particular, the modular low temperature DAC technology developed by Climeworks of Switzerland. It will discuss potential co benefits, in particular in relation to the Sustainable Development Goals (SDGs) of the United Nations and conclude by suggesting some policy approaches on how a climate relevant scale could be achieved in time."

Jacobson, Mark Z. (2019): The Health and Climate Impacts of Carbon Capture and Direct Air Capture

Jacobson, Mark Z. (2019): The Health and Climate Impacts of Carbon Capture and Direct Air Capture. In Energy Environ. Sci. DOI: 10.1039/C9EE02709B.

"Data from a coal with carbon capture and use (CCU) plant and a synthetic direct air carbon capture and use (SDACCU) plant are analyzed for the equipment’s ability, alone, to reduce CO2. In both plants, natural gas turbines power the equipment."

Sillman, J.; et al. (2019): Bacterial protein for food and feed generated via renewable energy and direct air capture of CO2: Can it reduce land and water use?

Sillman, Jani; Nygren, Lauri; Kahiluoto, Helena; Ruuskanen, Vesa; Tamminen, Anu; Bajamundi, Cyril et al. (2019): Bacterial protein for food and feed generated via renewable energy and direct air capture of CO2: Can it reduce land and water use? In Global Food Security 22, pp. 25–32. DOI: 10.1016/j.gfs.2019.09.007.

"This quantitative literature review conservatively estimated the direct land and water use of bacterial protein production relying on secondary data for the components of the technology and for the reference protein sources. A several times higher potential protein yield per land area can be achieved by this technology with approximately one-tenth of the water use compared to that required for soybean production."
