Project: Flexible Carbon Capture and Storage Modeling (Kleinman Center for Energy Policy)

"In collaboration with Colorado State University and with funding from ARPA-E, the team continues to work on computer modeling for natural gas power plants with carbon capture systems (NGCC) in a future with increased renewables on the grid. This system includes a solution that stores both hot and cold energy when the NGCC plant is not contributing to the grid (i.e. during peak solar hours): the stored heat circles back to the carbon capture system and the stored cold energy feeds the natural gas plant, improving efficiency while reducing emissions."

Project: Indirect Carbonation of Alkaline Waste (Kleinman Center for Energy Policy)

"Connected to mine remediation, lab researchers are exploring chemistry that could support the process of reverse mining, or backfilling mines with mine waste infused with CO2. This process would clean the atmosphere while offering mine owners a more valuable product—a qualified carbon offset. An additional health benefit occurs with mine waste composed of asbestos. Reacting CO2 with asbestos alters it from a fibrous mineral (that can be inhaled) into a more benign form."

Project: State Mapping Study (Kleinman Center for Energy Policy)

"In partnership with the Nature Conservancy, the lab is working on a custom plan to help the state of Nevada achieve its Net-Zero by 2050 goal—through decarbonization and carbon removal. The plan considers the state’s assets and liabilities—for example, Nevada has a lot of opportunities for geothermal and solar but doesn’t have many forests (for carbon sinks). The goal is to create a sliding scale of options—from more decarbonization and less carbon removal to the flip side. From there, the team hopes to apply this model to other states."

Akimoto, Keigo; et al. (2021): Climate change mitigation measures for global net-zero emissions and the roles of CO2 capture and utilization and direct air capture

Akimoto, Keigo; Sano, Fuminori; Oda, Junichiro; Kanaboshi, Haruo; Nakano, Yuko (2021): Climate change mitigation measures for global net-zero emissions and the roles of CO2 capture and utilization and direct air capture. In Energy and Climate Change, p. 100057. DOI: 10.1016/j.egycc.2021.100057.

"Many existing scenario studies show the need for large amounts of biomass energy with carbon dioxide capture and storage (BECCS) to achieve net-zero emissions, requiring high mitigation costs. This study provides comprehensive and cost-efficient technological portfolios for both energy supply and demand, and reveals the roles of carbon dioxide utilization (CCU) and direct air capture (DAC) for achieving global net-zero emissions by using a technology-rich global energy systems and climate change mitigation model which can assess them comprehensively, while considering several kinds of uncertainties. According to the analyses, DAC will be able to dramatically reduce emission reduction costs and alleviate dependence on BECCS. There are no feasible solutions for temperature increases below 1.5 °C in 2100 with 66% achievability under a temperature overshoot pathway unless DAC is used. Carbon free or nearly carbon free hydrogen plays important roles for net-zero emissions, and CCU helps increase the usability of hydrogen via synthetic fuels, and thus contributes to net-zero emissions. The relationships between DAC and CCU are very complex; the reductions in marginal abatement costs of carbon dioxide (CO2) due to DAC will reduce the roles of CCU around 2050 for many of the pathways to net-zero emissions. Meanwhile, for deeper reductions of CO2 emissions including net negative emissions in 2100, DAC will increase the roles of CCU by providing recovered CO2 from DAC, and also expand the opportunity for the use of recovered CO2 from fossil fuel combustion for synthetic fuels, because the related emissions are offset by larger negative emissions from the combination of DAC and CO2 storage (DACCS)."

Global Cement: Aalborg Portland Cement to launch carbon capture and storage project at Rørdal cement plant in 2022

"Denmark: Aalborg Portland Cement will begin construction of a carbon capture and storage (CCS) system at its Rørdal, North Jutland, cement plant. It will collaborate with Project Greensand CCS consortium partners to store the captured CO2 in drained oilfields below the North Sea. The company estimates that the Danish part of the North Sea has 16Gt of CO2 storage capacity, out of 300Gt under all EU waters. The endeavour aims to help Denmark to realise its targeted 70% reduction of CO2 emissions by 2030."

The Sydney Morning Herald: Taylor adds carbon capture and storage to clean energy agency’s plans

"Australia’s clean energy investment arm is including for the first time a commitment to fund carbon capture and storage projects, following the federal government’s controversial change to the agency’s remit in August.Energy and Emissions Reduction Minister Angus Taylor passed new regulations through Parliament to expand ARENA’s investment mandate to include carbon capture and storage and more uses of gas power."
