Government.no: The Norwegian Government continues with the planning of a demonstration project for CO2 capture, transport and storage

"Both the Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) point to CCS as a necessary option to reduce global greenhouse gas emissions in line with the climate goals at the lowest possible costs."

CarbonBrief: Why BECCS might not produce ‘negative’ emissions after all

"Bioenergy crops with carbon capture and storage (BECCS) is, perhaps, the most prominent of the various negative emissions techniques. There are many attractive features, since this technology would provide energy – thus reducing our need for fossil fuels – and remove CO2 from the atmosphere at the same time."

GlacierHub: Solar Geoengineering Could Limit Sea-Level Rise from Cryosphere

"Geoengineering, as it relates to climate change, falls into two categories. The first, atmospheric carbon removal, entails physically removing carbon dioxide from the air to reduce greenhouse gas concentrations and limit temperature rise. The second, solar geoengineering, involves injecting sulfur dioxide or another aerosol into the stratosphere to reflect a portion of incoming solar radiation, again limiting temperature rise."

Santori, G.; et al. (2018): Adsorption artificial tree for atmospheric carbon dioxide capture, purification and compression

Santori, G.; Charalambous, C.; Ferrari, M.; Brandani, S. (2018): Adsorption artificial tree for atmospheric carbon dioxide capture, purification and compression. In: Energy. DOI: 10.1016/j.energy.2018.08.090.

"Many well-established processes can remove carbon dioxide from the atmosphere but the real technological challenge consists of concentrating and compressing carbon dioxide at the conditions for long term geological storage, with efficient use of non-fossil energy sources. A thermally-driven, negative-carbon adsorption process for capture, purification and compression of carbon dioxide from air is proposed. The process is based on a series of batch adsorption compressors of decreasing size to deliver a compressed carbon dioxide stream to a final storage."

Science News: Faster way to make mineral to remove carbon dioxide from atmosphere

"Scientists have developed an accelerated way to produce magnesite, a mineral which can capture the greenhouse gas carbon dioxide from the atmosphere, at room temperature. Removing carbon dioxide from the atmosphere would slow global warming. This work takes a different approach to existing processes, and may make it economically viable, but it is at an early stage and is not yet an industrial process."

Pfrommer, T. (2018): Diverging Regional Climate Preferences and the Assessment of Solar Geoengineering

Pfrommer, T. (2018): Diverging Regional Climate Preferences and the Assessment of Solar Geoengineering. Heidelberg (Discussion Paper Series, 0654). DOI: 10.11588/heidok.00025204

"Solar Geoengineering (SG) is a set of potential technologies to counteract climate change. While SG can only imperfectly compensate for temperature changes at the regional level, studies assessing regional SG impacts indicated so far that regional temperature disparities from SG may not be as severe as previously thought. A shortcoming of that literature is its assumption that regions’ temperature preferences correspond to some historic baseline climate. I extend the main framework for examining regional SG impacts by allowing for regions to have temperature preferences diverging from the baseline climate, showing that the impact of these diverging preferences can be split into two components."

C2G2: What we don’t know about geoengineering and biodiversity

"On Montreal’s hottest day since records began, we met with leading technical experts to the Convention on Biological Diversity (CBD), to present a new Technical Briefing Paper exploring what we do and don’t know about geoengineering and biodiversity."

Politico: Europe mulls stripping carbon from the skies

"Carbon removal schemes range from planting lots of trees to more experimental methods to artificially suck up carbon. Some of those ideas are grouped under the label geoengineering, something that’s long been anathema because of fears that overt tinkering with the planet could lead to catastrophe."
