Carbon Management with DOE's Dr. Jen Wilcox
Inevitable
Exploring the Potential of Direct Air-Captured CO2
Exploring the potential use of direct air-captured CO2 for storage and feedstock, including a discussion on carbon conversion into diamonds and a major investment for CO2 injection in the United States.
Dr. Jen Wilcox serves as Principal Deputy Assistant Secretary of the US Department of Energy's Office of Fossil Energy and Carbon Management (FECM). Dr. Wilcox, an expert in carbon capture, authored the seminal textbook 'Carbon Capture' in 2012. Currently on leave as the presidential distinguished Professor of Chemical Engineering and Energy Policy at the University of Pennsylvania, she also serves as a senior fellow at the World Resources Institute, leading their carbon removal program.
In this conversation, we dive into Dr. Wilcox's transition from academia to the Department of Energy and explore the changing mandates under the Biden and Harris Administration. Key topics include direct air capture technologies, underground sequestration, and CO2 storage. The episode also touches on point source capture, technology advancements, tax credits, and incentives for carbon capture, including the extension of 45Q tax credits. Dr. Wilcox provides insights into the commercialization progress for carbon capture, market evolution, and the recent FECM carbon dioxide removal purchase pilot prize.
The discussion covers the power and heat requirements of direct air capture (DAC) and point source capture, along with solutions for reducing atmospheric levels of other greenhouse gases, including methane. This is a jam-packed episode that at times, hits topics at a macro level and at other times swoops down deep into technical descriptions of DAC chemistries. Whether you're exploring a career in carbon capture or actively developing technology solutions, there's something for everyone in this episode.
