Two Washington University Engineering faculty were guest editors of the January 2013 special issue of Environmental Science & Technology.
Young-Shin Jun, PhD, assistant professor, and Daniel Giammar, PhD, the Harold D. Jolley Career Development Associate Professor, both in Energy, Environmental & Chemical Engineering, worked for more than a year to compile nearly 40 articles in the special issue, which focuses on the environmental and geochemical aspects of geologic carbon sequestration. A third guest editor, Charles J. Werth, PhD, is from the University of Illinois at Urbana-Champaign.
E. Brook Haley, publications & creative design specialist in the School of Engineering & Applied Science, designed the issue’s cover.
Geological carbon sequestration is the practice of injecting carbon dioxide (CO2), captured from an industrial or energy-related source, such as a power plant or natural gas processing facility, into deep subsurface rock formations for long-term storage. It is also referred to as carbon capture and storage.
Jun says the practice is necessary to mitigate the impact of CO2 emissions on the environment, when contribute to climate change.
“As environmental engineers, it is our responsibility to ensure that we can do this safely,” Jun says. “We want to learn what kind of environmental impact this practice may have and if there are any chemical reactions after we inject the carbon dioxide deep into the earth. That is something important that we in the field are missing, and we want to bring attention to it.”
Articles in the issue include several critical review articles, as well as a look at three types of geologic carbon sequestration:
- Carbon dioxide dissolution in brines and adsorption on minerals relevant to storage formations under geologic sequestration conditions
- The physical/chemical process involved with wetting phenomena
- The examination of various processes relevant to the potential for leaks and transportation out of storage areas and monitoring for leaks.
About the cover:
Geologic CO2 sequestration is a promising option to mitigate adverse effects of climate change. To ensure its environmental sustainability, we must understand key geochemical reactions (from nano-scale to reservoir-scale) and their impacts on the reactive transport of CO2 and on environmental risk management.
