Blog.Castac.Org: Making Rain and Letting Shine: Geoengineer's Biopolitics

"Geoengineering is a diverse set of environmental technologies proposed to intervene strategically in Earth processes in order to combat climate change. Take for example, a plan to reduce solar radiation via aerosol clouds emitted from airplanes, or one that attempts to remediate ocean acidification by means of algae blooms created by dumping iron from ships."

Sara, Juliana; et al. (2015): Assessing relative importance and mutual influence of barriers for CCS deployment of the ROAD project using AHP and DEMATEL methods

Sara, Juliana; Stikkelman, Rob M.; Herder, Paulien M. (2015): Assessing relative importance and mutual influence of barriers for CCS deployment of the ROAD project using AHP and DEMATEL methods. In International Journal of Greenhouse Gas Control 41, pp. 336–357. DOI: 10.1016/j.ijggc.2015.07.008 

"Several carbon capture and storage (CCS) projects around the world were cancelled, delayed or are on hold due to different types of barriers, such as: economic, legal, social and technical. Previous works treat these barriers as independent factors, ignoring potential interactions and possibly providing wrong information. This paper presents the findings of a survey in which experts evaluate the main barriers hampering the deployment of the ROAD project, in the Netherlands."

Hardin Tibbs Blog: Can geoengineering be eco-friendly?

"As a geoengineering initiative this would be a far more potent environmental intervention than the fossil fuel industry, since it would take it only ten years to reverse what it has taken well over 100 years of fossil fuel use to achieve. It sounds too good to be true, because surely it’s an overriding objective to bring down today’s high carbon dioxide levels?"

Uygun, Murat; et al. (2015): Micromotor-Based Biomimetic Carbon Dioxide Sequestration: Towards Mobile Microscrubbers

Uygun, Murat; Singh, Virendra V.; Kaufmann, Kevin; Uygun, Deniz A.; de Oliveira, Severina D S; Wang, Joseph (2015): Micromotor-Based Biomimetic Carbon Dioxide Sequestration: Towards Mobile Microscrubbers. In Angewandte Chemie (International ed. in English). DOI: 10.1002/anie.201505155 

"We describe a mobile CO2 scrubbing platform that offers a greatly accelerated biomimetic sequestration based on a self-propelled carbonic anhydrase (CA) functionalized micromotor. The CO2 hydration capability of CA is coupled with the rapid movement of catalytic micromotors, and along with the corresponding fluid dynamics, results in a highly efficient mobile CO2 scrubbing microsystem."

Otto, Alexander; et al. (2015): Closing the loop. Captured CO2 as a feedstock in the chemical industry

Otto, Alexander; Grube, Thomas; Schiebahn, Sebastian; Stolten, Detlef (2015): Closing the loop. Captured CO2 as a feedstock in the chemical industry. In Energy Environ. Sci. DOI: 10.1039/C5EE02591E 

"Evaluating these environmental and economic benefits is important for promoting the further development of benign CO2 applications. Given the multitude of CO2 utilization reactions in the laboratory context, an initial assessment must be undertaken to identify those which have the most potential for future technical exploration and development."

Kuo, Kirsty A.; Hunt, Hugh E. M. (2015): Isothermal pumping analysis for high-altitude tethered balloons

Kuo, Kirsty A.; Hunt, Hugh E. M. (2015): Isothermal pumping analysis for high-altitude tethered balloons. In R. Soc. open sci. 2 (6), p. 140468. DOI: 10.1098/rsos.140468 

"This paper examines the pumping requirements of such a delivery system. Cases considered include delivery of hydrogen, sulfur dioxide (SO2) and powders as fluid-based slurries. Isothermal analysis is used to determine the variation of pressures and velocities along the pipe length. Results show that transport of small quantities of hydrogen to power fuel cells and maintain balloon buoyancy can be achieved at pressures and temperatures that are tolerable in terms of both the pipe strength and the current state of pumping technologies."

Lichtfouse, Eric; et al. (2015): Hydrogen production and remediation of carbon and pollutants

Lichtfouse, Eric; Schwarzbauer, Jan; Robert, Didier (2015): Hydrogen production and remediation of carbon and pollutants. Cham: Springer (Environmental chemistry for a sustainable world, volume 6).

Book including CDR methods. "This book details first the chemistry of hydrogen production from biomass. Solutions to the CO2 issue are given in three chapters, which describe CO2 photo catalytic reduction, CO2 sequestration in terrestrial biomass, and plants as renewable fuels. Further chapters review the selenium cycle in ecosystems, advanced processes to treat water and ecological ways to dye textiles. "
