From Carbon Sequestration Initiative
The Carbon Sequestration Initiative (CSI) will accelerate the safe deployment of geologic sequestration with underpinning basic science in geochemistry and subsurface flow and transport. The Pacific Northwest National Laboratory (PNNL) is making advancements in three key areas that will increase the accuracy of predicting the long-term storage of carbon dioxide and other emissions gases in deep geologic reservoirs: 1) a knowledge and data management platform, the Geologic Sequestration Software Suite (GS³), that stewards users through the modeling process; 2) an experimental suite, In Situ Supercritical Suite (IS³), to probe geochemical reactions under supercritical pressures and temperatures and 3) a modelling suite, Modelling Schemes Sequestration Suite (MS³).
GS³ is an extensible, dynamic and integrated computing environment that goes beyond the current work funded by the U.S. Department of Energy on individual simulators. IS³ is a group of one-of-a-kind instruments in EMSL (the Environmental Molecular Sciences Laboratory, a U.S. Department of Energy user facility located at PNNL that can be used to identify important reaction mechanisms in the caprock or borehole cement. These new science-based tools will provide a platform for national and international research collaborations to validate simulators and advance the science while, at the same time, provide access to domain users for application to field sites.
The initiative projects are managed under three focus areas that represent the development of the GS³ data and knowledge computational platform, the IS³ experimental capabilities and the MS³ modelling capabilities.
