Project: Electrochemical Direct Air Capture of CO2 using Redox-active Textiles (University of Michigan)

"The University of Michigan, in collaboration with the University of Massachusetts Amherst, will develop a technology that captures CO2 from the atmosphere using an electrochemical approach, rather than the temperature swing cycle which is typically powered by fossil fuel combustion. The team’s concept is a pH swing cycle that changes conditions between basic and acidic to capture and release CO2, respectively. Direct air capture (DAC) of CO2 by inexpensive renewable electricity could reduce the cost and improve the efficiency of DAC. The team aims to optimize the design of the cycle to achieve high rates of CO2 separation at low energy inputs."

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: 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."

Video: CNBC: Why Bill Gates Is Funding Solar Geoengineering Research

"Fires burning across the Amazon rainforest have renewed the debate about solutions to climate change. Bill Gates is backing the first high-altitude experiment of one radical approach called solar geoengineering. It's meant to mimic the effects of a giant volcanic eruption. Thousands of planes would fly at high altitudes, spraying millions of tons of particles around the planet to create a massive chemical cloud that would cool the surface. [...] The technology is not far from being ready and it's affordable, but it could cause massive changes in regional weather patterns and eradicate blue sky. [...]Watch the video to learn how it would work and hear the debate around the ethics and efficacy of solar geoengineering."

Podcast: Carbon Removal Newsroom: Biochar, carbon dioxide removal in the US, and geoengineering

"This week on Carbon Removal Newsroom, we’re starting off with an overview of biochar and discussing the main questions and concerns around this technology, including: How does biochar compare to other Carbon Dioxide Removal (CDR) methods? There is a lot of interest in making biochar, but does the market exist to use it? What can governments do to help scale up the use of biochar as a carbon removal technique? Are any governments taking action yet? Next, we transition to the CDR policy agenda in the United States. We look at the California Climate Crisis Act (AB 1395), which would Codify California’s commitment to achieve net-zero greenhouse gas emissions as soon as possible and no later than 2045. If passed, this bill will set California on course to design a more comprehensive policy framework for CDR than exists in any state so far."

McAfee, Kathleen (2021): Shall the American Association of Geographers Endorse Carbon Offsets? Absolutely Not!

McAfee, Kathleen (2021): Shall the American Association of Geographers Endorse Carbon Offsets? Absolutely Not! In The Professional Geographer, pp. 1–7. DOI: 10.1080/00330124.2021.1934879.

"The American Association of Geographers should not contribute to this illusion by endorsing offsetting. Instead we should take steps to reduce our own emissions and speak out clearly when our work has bearing on policy decisions and public perceptions about the climate crisis."

Energy.gov: DOE Announces Intent to Fund Direct Air Capture FEED Studies

"Today, the U.S. Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management (FECM), in collaboration with the Office of Nuclear Energy and the Office of Energy Efficiency and Renewable Energy’s Geothermal Technology Office, issued a notice of intent (NOI) for a Funding Opportunity Announcement (FOA) expected to support front-end engineering design (FEED) studies of direct air capture (DAC) combined with dedicated storage and coupled to existing low-carbon energy."

Luthria, Neva; et al. (2021): Policy Memo: An Approach to Scientific and Legislative Governance of Solar Radiation Modification Research in the United States

Luthria, Neva; Farrell, Steven L.; Paredes, Ingrid Joylyn (2021): Policy Memo: An Approach to Scientific and Legislative Governance of Solar Radiation Modification Research in the United States. In JSPG 18 (02). DOI: 10.38126/JSPG180207.

"We recommend that the US (1) stop blocking the UN from pursuing research into the impacts of SRM to allow for equitable governance options to be explored and (2) establish a national advisory committee on solar geoengineering."
