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."

Job: Software Engineer (Charm)

No Deadline

"Our mission is to reverse climate change and return the atmosphere to 280 ppm CO2. To pursue this challenge, we convert waste biomass into carbon-rich bio-oil and inject into permanent, underground storage wells as a form of carbon removal, or reform it to produce green hydrogen and syngas for industrial processes like steel, cement, and chemicals manufacturing. [...] As a software engineer at Charm Industrial you’ll be responsible for designing and implementing internal tools, control, data analysis, and automation for our little earth-saving robots. Each element of the system requires its own little bit of software - ladder logic on the PLCs, Python on the GUIs, C on low-level hardware, database work on the data side, and small linux scripts on the servers. In the intersection of all of these systems there’s always something interesting to work on."

[...] We are looking for a Mechanical Design Engineer to join our team! You might be a MechE that isn't scared away by a little chemistry, or a ChemE who might have dabbled in mechanical design! Your responsibilities as a design engineer will be to own one to many subsystems on our systems from end-to-end, with a focus on robust, creative and thoughtful design decisions. You will collaborate with the rest of the team on critical interfaces and high-level systems design. You will put your hardware through test situations early and often, to ensure consistency and stability in the field. Best and most importantly, your hardware will be critical in ensuring a better future for our planet."

Zhang, Xiaoyu; et al. (2021): High-Performance Binary Mo–Ni Catalysts for Efficient Carbon Removal during Carbon Dioxide Reforming of Methane

Zhang, Xiaoyu; Deng, Jiang; Pupucevski, Max; Impeng, Sarawoot; Yang, Bo; Chen, Guorong et al. (2021): High-Performance Binary Mo–Ni Catalysts for Efficient Carbon Removal during Carbon Dioxide Reforming of Methane. In ACS Catal., pp. 12087–12095. DOI: 10.1021/acscatal.1c02124.

"Dry reforming of methane (DRM) can convert greenhouse gases (CO2 and CH4) into value-added syngas (CO and H2), which is one of the promising approaches to achieve carbon neutrality. Designing coking resistant catalysts is still a challenge for an efficient DRM reaction. Here, we developed an efficient binary Mo–Ni catalyst through elucidating the promotional role of Mo in boosting the coking resistance of Ni-based catalysts during the DRM."

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."

Project: Oxide Looping for Direct Air Capture (Kleinman Center for Energy Policy)

"This project, underway at Pennovation, explores which reactive materials best remove CO2 from the air. In addition to selecting and testing different materials for effective mineral carbonation, the research team is also comparing CO2 uptake based on exterior conditions like air temperature and humidity."

Tang, Weiyi; et al. (2021): Widespread phytoplankton blooms triggered by 2019-2020 Australian wildfires

Tang, Weiyi; Llort, Joan; Weis, Jakob; Perron, Morgane M. G.; Basart, Sara; Li, Zuchuan et al. (2021): Widespread phytoplankton blooms triggered by 2019-2020 Australian wildfires. In Nature 597 (7876), pp. 370–375. DOI: 10.1038/s41586-021-03805-8.

"Droughts and climate-change-driven warming are leading to more frequent and intense wildfires1,2,3, arguably contributing to the severe 2019–2020 Australian wildfires4. The environmental and ecological impacts of the fires include loss of habitats and the emission of substantial amounts of atmospheric aerosols5,6,7. Aerosol emissions from wildfires can lead to the atmospheric transport of macronutrients and bio-essential trace metals such as nitrogen and iron, respectively8,9,10. It has been suggested that the oceanic deposition of wildfire aerosols can relieve nutrient limitations and, consequently, enhance marine productivity11,12, but direct observations are lacking. Here we use satellite and autonomous biogeochemical Argo float data to evaluate the effect of 2019–2020 Australian wildfire aerosol deposition on phytoplankton productivity."

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)."
