Performer: PNNL - Pacific Northwest National Laboratory

Project No: FWP-58159


Program Background and Project Benefits

The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) is helping to develop technologies to capture, separate, and store carbon dioxide (CO2) to reduce green-house gas (GHG) emissions without adversely influencing energy use or hindering economic growth. Carbon capture and sequestration (CCS)—the capture of CO2 from large point sources and subsequent injection into deep geologic formations for permanent storage—is one option that is receiving considerable attention. Without CCS technologies, greenhouse gas emissions would continue to contribute to global climate change.

NETL is committed to advancing geologic carbon sequestration technology through funded research projects focused on removing obstacles to commercial- scale carbon sequestration deployment. Both existing and newly developed CCS technologies hold great promise to significantly reduce emissions from fossil fuels, but the engineering, economic, and environmental viability of these technologies must be assessed, tested, and validated. Demonstrating clean and economically viable electricity production from fossil fuels as well as acceptance of carbon sequestration by the public are of critical importance to wide-scale deployment.

NETL is providing funding to Pacific Northwest National Laboratory (PNNL), one of DOE’s multi-program, multi-disciplinary research laboratories to conduct research studies on key topics critical to the success of geologic sequestration, including developing a risk assessment research working group, developing a global fossil energy technology strategy, investigating promising geologic storage formations (basalts), and developing lower cost carbon capture and geologic storage technology.

The applied research that PNNL proposes is intended to advance CCS by developing a common framework for risk analysis for large-scale injection tests, and to reduce the overall cost of electricity through co-sequestration, and to investigate the potential for newer, promising geologic storage formations to store CO2. Benefits gained by this research are vital to the success of CO2 sequestration over the long term. This work is focused on investigating the necessary science that will lead towards large-scale deployment of geologic CO2 sequestration technologies.
