Carbon capture and sequestration (CCS) is a process that involves capturing carbon dioxide emissions from industrial sources, such as power plants or manufacturing facilities, and storing them underground or using them for other applications instead of releasing them into the atmosphere.

The podcast episodes discuss the role of CCS in decarbonizing hard-to-abate sectors, its potential and limitations, and the policy implications surrounding this technology. For example, Episode #53176 focuses on the EPA's reliance on CCS as a basis for setting emission standards for power plants, while Episode #54311 explores the US government's investment in direct air capture (DAC) facilities and the potential of CCS in decarbonization efforts.

Additionally, Episode #54423 examines the prominent role of CCS in integrated assessment models (IAMs) used in climate science, and how the assumptions made in these models can impact the prominence of CCS in future climate scenarios. The episodes also discuss the potential challenges and limitations of CCS technologies.
