Air and Climate Change Research

Dave Kirchgessner

Dave Kirchgessner is a senior research scientist/geologist in the US EPA Office of Research and Development, National Risk Management Laboratory, Air Pollution Prevention and Control Division, (APPCD), Atmospheric Protection Branch (APB). Dave received a B.A. in economics and an M.S. in geology from the State University of New York at Buffalo, followed by a Ph.D. in geology from the University of North Carolina at Chapel Hill. He later returned to UNC to complete a Master's degree in public health administration.

Research Area
Dr. Kirchgessner joined EPA in 1975, having spent the prior three years as a professor of geology. During his tenure, he has worked on numerous fossil fuel-focused projects including the analysis of trace elements in coal and coal wastes, coal preparation, coal gasification, fluidized bed combustion, and the demonstration-scale limestone injection multi-stage burning project.

Dave has worked in the climate change area for most of the last seven years where he has focused on quantifying methane emissions from the coal, petroleum, and natural gas industries. He has shifted the focus of his work and is participating in a project to quantify mercury emissions from the natural gas and petroleum industries, and from refineries and petrochemical plants.

Currently responsible for research on estimation and mitigation of methane emissions from coal mining and natural gas industries.  Formerly responsible for directing both in-house and extramural research on characterizing and enhancing the SO2 capture potential of sorbents in the LIMB process.  Prior responsibilities included determining the pollution potential of U.S. coal resources, and of wastes from combustion, fluidized bed combustors and synfuels production.

In addition, Dave oversees the Greenhouse Gas Environmental Technology Verification program, which has been established to supply credible third party performance data on technologies which show promise of controlling greenhouse gases but have been underutilized.
