CMI Technology

CMI Technology studies energy conversion in conjunction with carbon dioxide (CO2) capture and storage. Capture studies include both biological and fossil fuel inputs. Storage studies emphasize leakage pathways and now also investigate storage in shales. A program on advanced batteries has begun.

Research Highlights – At a Glance

Michael Celia: The capture and belowground storage of carbon dioxide (CO2) emissions from power plants and other sources has the potential to mitigate climate change by preventing the release of these emissions into the atmosphere. The presence of abandoned oil and gas wells in areas that are otherwise suitable for geological storage may compromise storage integrity. Both CO2 and brine may leak out from old wells, potentially contaminating groundwater supplies and possibly leading to CO2 leakage into the atmosphere. The Celia group has combined modeling approaches with empirical data collection to estimate the risks of leakage along abandoned wells in the Wabamun Lake area of Alberta, Canada.

Howard Stone: Climate changes involve atmospheric motions, ocean flows, and evolution of ice on land and in the sea. These dynamics are necessarily interrelated; insights into individual processes can help to illuminate poorly understood aspects of global climate dynamics, such as factors affecting the maintenance of sea ice cover in the Arctic basin. Sea ice cover can impact fresh water fluxes, local ecology, and ocean circulation. The Stone group is providing simplified models for understanding the movement of ice through narrow straits, which can affect flow and mixing in the ocean.

Daniel Steingart: Building more energy-efficient systems depends on the ability to optimize and regulate the performance of energy-storing batteries. The Steingart group has developed a new type of zinc material that overcomes many of the limitations of zinc storage batteries. This material may be useful for long-term energy storage in grid-scale and electric vehicle applications.
