The Role of LDES in Ensuring a Renewable Energy Supply 24/7

The smarter E Podcast Episode 165 | February 8, 2024 | Language: English

Renewable energy is booming worldwide, but how can we further turbocharge the development and create a fully decarbonized, secure and reliable energy system? In this episode, we delve into the role of long duration energy storage (LDES) in ensuring a renewable energy supply 24/7. We will define, where LDES positions itself between short terms storage and hydrogen and of course, we will dive into the latest developments and market potentials about flow batteries.

Tune in for an enlightening conversation with our expertes Julia Souder, CEO of LDES Council and Alan Greenshields, Director EMEA at ESS Inc.


  • 02:40 What exact role do Long Duration Energy Storage (LDES) play in the transition toward?
  • 07:28 Overview of the various types of electrochemical long-duration energy storage solutions, including static batteries, flow batteries and more.
  • 21:03 About the enormous potential using the example of the Leag power plant location in Boxberg, Lausitz, Germany.
  • 27:51 What barriers still exist for widespread deployment? And what can we do to accelerate development?
