Peter Psarras

Research Assistant Professor, University of Pennsylvania

Peter Psarras is a research assistant professor in chemical and biomolecular engineering at the School of Engineering and Applied Sciences. He oversees the direction of Jennifer Wilcox’s lab, focusing on carbon dioxide removal and carbon capture.

His research involves techno-economic and life-cycle assessments of carbon capture, utilization and storage, and carbon dioxide removal systems, specifically in identifying regional opportunities for deployment. Peter received his bachelor’s degree in chemistry from Miami University in 2005 and his Ph.D. in chemistry from Cleveland State University in 2014

Susan D. Hovorka

Senior Research Scientist, UT Austin

Susan D. Hovorka is a Senior Research Scientist at the Bureau of Economic Geology, Jackson School of Geosciences, at The University of Texas at Austin. She has a BA in geology from Earlham College and an MA and PhD from the University of Texas. She has worked on diverse topics related to water quality protection, waste storage in bedded salt, and reservoir characterization. Her current research focuses on assessment of effectiveness of subsurface geologic sequestration of CO2 as a mechanism for reducing atmospheric greenhouse gas emissions. Hovorka is the principle investigator of the Gulf Coast Carbon Center, an industry/academic partnership working on economically viable approaches to geologic sequestration of CO2. She has recently completed leading a research team in completion of the two-phase Frio Pilot, a first US field test of storage of CO2 in brine-filled sandstones also funded by DOE-NETL.

In this Episode

Geologic storage plays a crucial role in removing carbon from the atmosphere, offering a means of long-term storage for CO2. Building on existing comprehensive research on this topic, Roads to Removal researchers conducted a new analysis to determine the distribution and estimated costs of geologic storage resources, and CO2 transportation methods (in order to get CO2 from where it’s captured, to where it can be stored).

The report found that pipelines and barges are the most cost-effective transport methods for regions that will see a lot of CO2 transport, but trucking is the most economical method to transport shorter distances.

The geologic storage analysis includes two new elements. First, it maps the “storage window” where sedimentary rocks are at the right depth to retain CO2 as a dense fluid and enable CO2 injection. Second, it factors in new costs such as how storage volume impacts land-leasing costs, characterization and monitoring expenses, and the benefits to communities. Additionally, the analysis estimates costs on a project basis, allowing developers to find suitable storage options for removal projects based on desired costs.

Over half of the US has potential for CO2 storage, mainly in well-studied areas in the Gulf Coast and dozens of inland basins. Costs vary depending on location and rock formations, with mean storage costs of less than $20/tonne in some areas and higher costs in others.
