CMI Technology

CMI Technology explores the integration of intermittent renewable energy (wind and solar) into electricity grids, as affected by carbon policy and renewable energy policy—including the evolving roles for 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 also investigate storage in shales. Work also continues that is directed toward maximizing energy storage in batteries.

Research Highlights – At a Glance

Michael Celia: In order to have a significant impact on the carbon problem, very large amounts of captured CO2 need to be injected underground, with quantities reaching gigatonnes of CO2 per year by mid-century. The Celia group has developed models for large-scale injection, including pressure responses and associated pressure management schemes, and applied these to realistic injection scenarios in the Illinois Basin of North America, with simulated basin-wide injection rates exceeding 200 Mt CO2/ yr. Results indicate that if carbon capture and storage is to be implemented at the scale required to impact the carbon problem, such basin-wide analyses will need to be performed and appropriate management of pressure developed and implemented.

Ian Bourg: The objective of this initiative is to resolve the physics of soil carbon storage. The carbon storage capacity of soils is known to increase significantly with clay content, and in particular with the content in swelling clay minerals (smectites), but the cause of this relationship remains unknown. Using atomistic-level simulation methodologies, the Bourg group was able to model fully flexible clay particles surrounded by water and interacting with dissolved organic compounds. These results will enable more accurate Earth System Model predictions of the soil carbon sink and inform practical strategies for enhancing this important carbon sink.

Daniel Steingart: We are studying a fundamental question in battery research – whether apparently negative and inevitable physical phenomena in an electrochemical cell, such as corrosion and anisotropic growth, can be exploited for benefit. We use various imaging techniques to examine the deposition and removal of plate metals during cell operation and in conditions that emulate practical usage patterns.
