According to the IEA, heat is the world’s largest energy end use, accounting for almost half of global final energy consumption in 2021, significantly more than electricity (20%) and transport (30%). Of that, industrial processes are responsible for 51% of the energy consumed.

In this episode, co-hosts Thomas Obermeier and Ellie McDonald sit down with John O'Donnell, founder and CEO of Rondo Energy, which is seeking to provide low-cost zero-carbon industrial heat through its Rondo Heat Battery. We discuss why industrial heat has historically been seen as a hard to decarbonize industry, how Rondo is seeking to change that by deploying its Heat Battery, and how its product differs from other energy storage technologies.
