„This conference focuses on better understanding the processes and impacts associated with radiation management. This includes processes specific to individual methods, the projected climate response and its uncertainties, and the impacts, including those in the developing world, as well as the engineering aspects and the design of research to address risk.“
„Today, John Delaney announces[nbsp]his campaign plan to increase investment in negative emissions technology (NET).[nbsp]Delaney calls for an end to subsidies for fossil fuels and for a $5 billion annual subsidy for negative emissions technology. Combined with a carbon tax, innovation in negative emissions technologies can lead to net zero carbon by 2050.“

„Separation would help minimize the negative impacts that promises and deployments of negative emissions could have on emissions reduction, arising from effects such as temporal trade-offs, excessive offsetting, and technological lock-in. Benefits for international, national, local, organizational, and sectoral planning would arise from greater clarity over the role and timing of negative emissions alongside accelerated emissions reduction.“

„[nbsp]In this contribution, we study three distinct CCS-based processes which combine natural gas and biomass capable of producing low-, or carbon-negative power. Both fuel supply chains are considered in order to quantify the net overall CO2[nbsp]emissions. An important insight is the configuration-specific impact of biomass co-combustion on the overall carbon intensity of power generated.“
„When online payments entrepreneur Stripe last week declared its[nbsp]intention[nbsp]to achieve “negative emissions” — by funding carbon removal projects, not just traditional offsets — I could practically hear Nori CEO Paul Gambill cheering from the blockchain startup’s Seattle headquarters.“
„The Center on Global Energy Policy at Columbia University’s School of International and Public Affairs seeks a Staff Associate (Officer of Research) for a major research initiative on financing and policy design for carbon management, including carbon capture and storage, CO2 use, and CO2 removal.“
„Scientists are experimenting with new genetic modification[nbsp]technology[nbsp]that “supercharges” plants to enhance what they already excel at– sequestering carbon.“
Möller, I. (2019): The Emergent Politics of Geoengineering. Lund: Lund University.
„This thesis examines the role of science in the earliest stages of the political process. It does this by studying the emergence of ‘geoengineering’ on the political agenda. The term describes a set of ideas on how to stabilize global temperature by intervening into the Earth’s natural systems, and was subject to a strong taboo in the scientific community until the mid-2000s.“
Liu, X.; Miao, R.; Lindberg, P.; Lindblad, P. (2019): Modular engineering for efficient photosynthetic biosynthesis of 1-butanol from CO 2 in cyanobacteria. In: Energy Environ. Sci. 3, S. 969. DOI: 10.1039/C9EE01214A.
„Cyanobacteria are photoautotrophic microorganisms which can be engineered to directly convert CO2 and water into biofuels and chemicals via photosynthesis using sunlight as energy. However, the product titers and rates are the main challenges that need to be overcome for industrial applications. Here we present systematic modular engineering of the cyanobacterium Synechocystis PCC 6803, enabling efficient biosynthesis of 1-butanol, an attractive commodity chemical and gasoline substitute.“
Visioni, D.; MacMartin, D.; Kravitz, B.; Tilmes, S.; Mills, M.; Richter, J.; Boudreau, M. (2019): Seasonal Injection Strategies for Stratospheric Aerosol Geoengineering. In: Geophys. Res. Lett. 124 (6), S. 7. DOI: 10.1029/2019GL083680.
„Simulations of stratospheric aerosol geoengineering have typically considered injections at a constant rate over the entire year. […] We simulated single‐point injections of the same amount of SO2 in each of the four seasons and at five different latitudes (30°S, 15°S, equator, 15°N, and 30°N), 5 km above the tropopause. Our findings suggest that injecting only during one season reduces the amount of SO2 needed to achieve a certain aerosol optical depth, thus potentially reducing some of the side effects of geoengineering. We find, in particular, that injections at 15°N or 15°S in spring of the corresponding hemisphere results in the largest reductions in incoming solar radiation.“
