WEBINAR, 9 July | Energy storage is not whiskey – blends are best!

Tuesday 9th July 2024, 15:00 – 16:30 BST.



Decarbonising energy requires that we reconcile the differences between natural demand (how much electricity we would use at any given time if there were no incentives to do differently) and supply. Because much of our future primary energy supply will be drawn directly from renewables, the supply side resource will be quite variable. Several different measures are available to reconcile the two sides but of those and among these options, energy storage is very likely to play a hugely important role. This webinar focuses on “the benefits of the blend”. In theory at least, we could operate a net-zero energy system using just one type of storage but modelling is increasingly showing that blends of multiple types of storage will provide the lowest-cost systems. In this webinar we will hear about the four main ranges of discharge-duration for energy storage and the technical solutions that suit each of those four ranges  best.

Chair:  Professor Seamus Garvey, University of Nottingham.

Seamus Garvey is a Professor of Mechanical at the University of Nottingham and an expert in the roles that energy storage solutions will achieve in net zero energy systems. He has been passionately vocal over almost 20 years on the elucidation of how mechanical energy storage can and will play a major role in the future and he leads a Task under the IEA Technology Collaboration Program on Energy Storage focused on medium-duration solutions.


Prof. Keith Pullen, Chief Technical Officer, Levistor Ltd.

Keith will discuss the roles that flywheels can play in storing energy over very short periods – cycled millions of times

Keith began his career with 6 years at Rolls-Royce followed by 2 years in oil and gas. Becoming an academic at Imperial College in 1992, his patents on microturbines underpinned Turbo Power Systems. Appointed Chair at City University of London in 2010, breakthrough research on flywheel energy storage led to Levistor Ltd, CTO role and RAEng Enterprise Fellowship.

Dr. John-Joseph Marie, Principal Analyst for Energy Storage at The Faraday Institution. 

JJ will address the expanding role that stationary batteries can serve in electricity grid support for times (mainly) below 10 hours.

John-Joseph Marie works as Principal Analyst for Energy Storage at The Faraday Institution. His responsibilities include authoring Insights and other Faraday Institution reports, as well as carrying out techno-economic modelling work. Prior to joining the Faraday Institution, he completed his PhD on Lithium-ion cathode development at the University of Oxford under the supervision of Prof. Peter Bruce. His passions include the development of energy storage technologies and sustainable development.

Nerea Martinez Hipolito, Hydrogen Intelligence Service Research Manager at LCP Delta. 

Nerea will focus on how hydrogen can balance-up supply and demand mismatches over very long timescales – typically exceeding 200 hours.

Nerea manages the hydrogen research program at LCP Delta, with a focus on advancing hydrogen activities across Europe. Through her work, she develops market intelligence reports, models and forecasts, and engages with stakeholders across the whole hydrogen value chain – including storage operators – to understand the realities the sector is facing. Nerea holds a MEng in Mechanical Engineering with Renewable Energy from the University of Edinburgh.
