Over the next year, CMI investigators will continue to extend their core research and expand into new areas.

Capture

In the Capture Group, work on polygeneration of electricity, hydrogen, and liquid fuels will remain a primary focus, but with a new emphasis on roles for biomass as well as coal systems with carbon capture and storage in reducing emissions. Biomass analyses will be expanded to consider different biomass sources, production of synthetic fuels other than DME, and coprocessing of coal and biomass in the same facility. Moreover, the collaboration with Tsinghua University in Beijing on polygeneration from coal will be extended to consider coal-biomass hybrid schemes. On the combustion front, the group will study high power density approaches to avoiding pre-ignition, knock, and NOx emissions.

Storage

The Storage Group will spend the next year analyzing both lab and field cements, and developing new cements for durability testing that mimic the original composition of recovered well cements. In the realm of modeling, upscaling studies will be expanded, analytical solutions will be applied to a set of potential injection sites in Alberta, and the Dynaflow model will be used to simulate CO2 injection at the Mountaineer power plant in West Virginia, as well as being expanded to include additional chemistry.

Science

In the Science Group, studies of both long-term and short-term variability of carbon sources and sinks will continue through paleoclimate studies, ocean modeling, and measurements of atmospheric composition. In addition, the group will build on its success in inversion modeling of both ocean and terrestrial carbon sinks to assemble a Carbon Observing System that will diagnose current carbon cycle behavior as well as predicting the future behavior of carbon sources and sinks.

Integration

The Integration Group will continue to place research results in a broader context, exploring the policy implications of different carbon mitigation paths and communicating CMI research results to the larger community. The group plans to analyze the wedges concept in an energy security context, and to continue to extend its outreach to the non-academic community.
