Hydrocarbon fuels come almost exclusively from underground. We burn the coal or oil to obtain energy - and for hundreds of years, we have then allowed the resulting carbon dioxide to simply enter the atmosphere. A major aspect of current plans to manage the climate change resulting from the accumulated carbon dioxide is the effort to capture that carbon dioxide before it enters the atmosphere, and put it back underground. Particularly for large power plants and factories, this will make it possible to continue using hydrocarbon fuels without degrading the climate.

In this presentation you will learn about the role that underground storage of carbon dioxide can play in helping avoid damaging climate change, and the scientific challenges that face us in trying to keep the atmospheric load of carbon dioxide from continuing to grow due to burning fossil fuels.

Dr. Roger Aines

Energy and Environment Directorate
Lawrence Livermore National Laboratory

Roger is a member of the Energy and Environment Directorate at Lawrence Livermore National Laboratory, where he leads the geochemistry group. Roger holds a Bachelor of Arts degree in Chemistry from Carleton College, and Doctor of Philosophy in geochemistry from the California Institute of Technology.


Roger's research interests include the in situ degradation of organic chemicals through heating, simulation of steam-driven underground processes in heterogeneous media, and the mechanisms of thermally-assisted remediation. A key research area for Roger has been the coupling of active remediation methods to longer-term, self actuating methods like oxidation and bioremediation.



Ken Wedel

Earth Science Teacher
Tracy High School, Tracy Unified School District

Ken Wedel teaches Earth Science and Earth Science for English Language Learners at Tracy High School in Tracy, California. He developed the Earth Science program at Tracy High School, and has worked on curriculum mapping and curriculum alignment to the California State Standards for both high schools in Tracy. Ken has been involved with the Science Olympiad competition at the regional level for four years and enjoys advising the Tracy High School Team. Ken also works with Action Learning Systems creating California Earth Science Standards based benchmark tests. He has his Bachelor of Science Degree in Geology California State University, Stanislaus.



When not teaching, Ken's interests include black powder rifles, backpacking the Sierra Nevada Mountains and exploring national parks with his family (which includes convincing his 8 year old son and 11 year old daughter that rocks are cool).
