The world faces a critical challenge: how to meet growing energy demand while urgently reducing carbon dioxide emissions. It means the global energy system must change. 
Will innovation come to the rescue? How will renewable energy evolve? Does the oil and gas industry have a future? Will batteries, hydrogen or even blockchain alter the way we live, work and travel? 
The Energy Podcast by Shell explores these questions. We speak to the engineers at the pioneering edge of science and technology, the experts tracking progress towards the goals of the Paris Agreement, and the entrepreneurs working to drive the change.
