The podcast episodes discuss renewable natural gas as an emerging technology and area of focus for companies and industries seeking to reduce greenhouse gas emissions and support the transition to a more sustainable energy system.

In Sustainable Project Finance with Nexus PMG, the CEO of Nexus PMG highlights renewable natural gas production from anaerobic digestion of waste streams as one of the firm's areas of focus. Similarly, Is BP's Shift for Real? and The Devious Plan to Keep Us Hooked on Gas explore the natural gas industry's promotion of renewable natural gas as a response to policy changes and public pressure to move away from fossil fuels.

The Are Ancient Bugs the Key to Storing Wind and Solar? episode goes into more technical detail, discussing a bioreactor system that uses microbes to convert excess renewable electricity and industrial CO2 into renewable methane gas that can be injected into existing natural gas pipelines.
