Goeppert, Alain; et al. (2012): Air as the renewable carbon source of the future: an overview of CO2 capture from the atmosphere

Goeppert, Alain; Czaun, Miklos; Surya Prakash, G. K.; Olah, George A. (2012): Air as the renewable carbon source of the future: an overview of CO2 capture from the atmosphere. In: Energy Environ. Sci. 5 (7), pp. 7833-7853.

"The present article reviews methods developed for the capture of CO2 directly from the air as well as their advantages and drawbacks. While strong bases such as sodium hydroxide and potassium hydroxide could be used, their regeneration is energy intensive, requiring high temperatures."

Yale Environment 360: Rethinking Carbon Dioxide: From a Pollutant to an Asset

Marc Gunther writing about CDR technologies. "Three startup companies led by prominent scientists are working on new technologies to remove carbon dioxide from the atmosphere. The scientific community is skeptical, but these entrepreneurs believe the process of CO2 removal can eventually be profitable and help cool an overheating planet."

Bipartisan Policy - Task Force On Climate Remediation Research: Geoengineering: A National Strategic Plan for Research on the Potential Effectiveness, Feasibility, and Consequences of Climate Remediation Technologies

Leading experts on climate change science and technology comprising the Bipartisan Policy Center’s (BPC) Task Force on Climate Remediation Research today released a report calling for a coordinated federal research program to explore the potential effectiveness, feasibility, and consequences of climate remediation technologies.

"This report presents the conclusions of the Task Force on Climate Remediation Research, which was convened
by the nonprofit Bipartisan Policy Center in March 2010 to develop recommendations for the U.S. government
concerning geoengineering research and oversight policy. Participants included leaders from the scientific,
science policy, foreign policy, national security, legal, and environmental communities who together brought a wide
range of perspectives and expertise to the task force."

GeoEngineering - Chance oder Gefahr für die Erde?

"Das Max-Planck-Forum erörtert Für und Wider der derzeitigen Möglichkeiten der Geo-Ingenieure und fragt nach den aktuellen Handlungsspielräumen. Brauchen wir GeoEngineering wirklich oder ist es nur ein bequemer Ausweg für Politiker, das globale Klimaproblem ohne schwierige diplomatische Verhandlungen in den Griff zu bekommen?"

Podiumsdiskussionsgäste: Prof. Dr. Meinrat Andreae, Direktor am Max-Planck-Institut für Chemie, Mainz
Dr. Hauke Schmidt, Max-Planck-Institut für Meteorologie, Hamburg
Prof. Dr. Carl Friedrich Gethmann, Institut für Philosophie, Universität Essen-Duisburg

SPICE-Project

The project will investigate the feasibility of one so-called geoengineering
technique: the idea of simulating natural processes that release small particles
into the stratosphere, which then reflect a few percent of incoming solar
radiation, with the effect of cooling the Earth with relative speed.
