Visioni, Daniele; et al. 2020: “What Goes up Must Come down: Impacts of Deposition in a Sulfate Geoengineering Scenario.”
Visioni, Daniele, Eric Slessarev, Douglas MacMartin, Natalie M Mahowald, Christine L Goodale, and Lili Xia. 2020: “What Goes up Must Come down: Impacts of Deposition in a Sulfate Geoengineering Scenario.”[nbsp]Environmental Research Letters. https://doi.org/10.1088/1748-9326/ab94eb.
„We consider here an extreme sulfate geoengineering scenario necessary to maintain temperatures at 2020 levels while greenhouse gas emissions continue to grow unabated. We show that the amount of stratospheric sulfate needed could be globally balanced by the predicted decrease in tropospheric anthropogenic SO2 emissions, but the spatial distribution would move from industrialized regions to pristine areas. We show how these changes would affect ecosystems differently depending on present day observations of soil pH, which we use to infer the potential for acid-induced aluminum toxicity across the planet.“
„Although reductions in greenhouse gas emissions continue to be inadequate to prevent dangerous climate change,[nbsp]solar geoengineering[nbsp]appears able to substantially reduce climate risks. More research, including outdoor experiments, is needed to reduce critical uncertainties. This could pose some environmental risks and — arguably more importantly — will raise diverse social concerns, such as research “sliding” into undue deployment. For these reasons, some additional governance of solar geoengineering may be warranted.“
National Carbon Center: National Carbon Capture Center expands testing of carbon capture for negative carbon technologies
„Strengthening its commitment to energy innovation, Southern Company, in partnership with the U.S. Department of Energy (DOE), has announced an expanded focus for the National Carbon Capture Center.“
„There is more than enough global capacity to capture and store enough carbon dioxide (CO2) to meet climate-change targets, a study has found.“
„Sweden’s[nbsp]largest test facility for carbon dioxide capture has begun operation at Preem’s refinery in Lysekil. Within the pilot project `Preem CCS‘, the entire value chain will be analyzed – from the capture of carbon dioxide to its storage. The outcome of the project will enable more companies to use the technology and reduce their carbon dioxide emissions.“
„If the world is to meet the Paris Agreement and all energy-related sustainable development goals, roughly 2,000 carbon capture and storage (CCS) facilities need to be operating by 2040, delivering 7% of cumulative emissions reductions.“
„MAN Energy Solutions has been awarded a contract for the engineering of three RG compressor trains for a carbon capture, utilization and storage project in the Netherlands. The Port of Rotterdam Authority, Energie Beheer Nederland B.V. (EBN) and N.V. Nederlandse Gasunie are jointly developing the ‘Porthos’ (Port of Rotterdam CO₂ Transport Hub and Offshore Storage) project, which has been recognized by the European Union as a Project of Common Interest (PCI).“
Business Green: Anatomy of a moonshot: Microsofts Lucas Joppa on CO2 removal, supply chains and building a carbon negative future
„Tech giant’s chief environmental officer talks to BusinessGreen about the firm’s ambitious plan to remove all CO2 it has generated since its foundation in 1975.“
