Medium Duration Energy Storage 2022

March 16th, 2022

The importance of Medium Duration Energy Storage 

As the UK decarbonises its economy, offshore wind turbines and solar PV panels will deliver increasingly larger fractions of the country’s energy demand. 

Energy storage will become one of the main mechanisms to maintain a balance between electricity generation and demand in a renewable-dominated electricity grid. 

Energy storage will be required over a vast range of discharge times, going from milliseconds up to several months.  

This event focuses on the medium duration range (between 4 to 200 hrs), which is best handled by thermo-mechanical solutions.  

Following a very successful previous meeting in 2020, this event will provide an updated view on medium duration energy storage and new technologies being developed. The event will bring academics, industrial stakeholders, and policy makers together to discuss:  

  • what is the extent of the role for medium duration energy storage? 

  • what are some of the current blockers? 

  • what new policies are required to support the deployment of medium duration storage technologies.  

Medium-duration energy storage 2022 is taking place on 16th March to addess these questions. It is being delivered as a hybrid event with a physical base at the IMechE headquarters (One Birdcage Walk) in London.

Entrance is FREE but there is a limit of 60 people in the room, so book your place now! The meeting will be broadcast online in real time.
