Ep 9 | How Can Capturing Carbon and Monitoring Methane Play a Role in the Energy Transition?

In 2022, global greenhouse gas (GHG) emissions reached a high of 53 billion metric tons of CO2 equivalent. To bring that down to net zero, we can either stop emitting GHGs into the atmosphere, or we can pull out CO2 that has already been emitted. In this episode, we focus on two solutions to address areas where energy emissions are hard to abate.  One solution is carbon capture and sequestration, or CCS, which involves capturing CO2 from the air and storing it underground. In the first half of this episode, we speak with Dr. Saro Meguerdijian, a researcher at the Los Alamos National Laboratory in New Mexico, who explains what CCS is and how it works, as well as the crucial role it can play in addressing our growing carbon emissions. Another solution is monitoring methane emissions from oil and gas operations to identify and mitigate leaks and flares. This has become a hot topic lately as methane has accounted for about 30% of global warming since the Industrial Revolution and is 80x more potent at warming than carbon dioxide over a 20-year period. A lot of methane leaks into the atmosphere from oil and gas operations, and recent studies have found much higher rates of leakage from natural gas production than previously known. Thus, methane leaks can make natural gas just as bad as coal in contributing to climate change. In the second half of this episode, we speak with two graduate students, Will Daniels from the Colorado School of Mines and Rachel Day from Colorado State University, about methods for detecting methane emissions from oil and gas production and the role that data might play in reducing these emissions.  00:00 Interview with Dr. Meguerdijian 02:30 Interview with Will Daniels and Rachel Day 01:03:46 Concluding Remarks   Don’t forget to subscribe to our podcast so you can automatically get access to our new episodes – you can find us on Apple, Spotify, YouTube, or wherever you get your podcasts.
