If renewable energy was iron, then storage would be vitamin C, playing a vital role in the energy system’s ability to absorb the variable renewable energy sources available to us. However, beneath the umbrella term that is “storage” lies a broad range of technologies, from the lithium-ion batteries that we are all familiar with, to compressed hydrogen stored in salt caverns.

But what are the strengths of each of these storage technologies, and what roles can they individually play in replacing the various characteristics that we lose as we make the move from fossil fuels to renewable energy? Is hydrogen the answer to all our problems, or do we need to stop looking to it as a silver bullet on the horizon?

To find out, Paddy Finn talks to Frank Burke, Technical Advisor to the Irish Energy Storage Association, and Rory Monaghan, National University of Ireland Galway, who has specialised in hydrogen for almost 20 years.

The Electricity Exchange is a series of discussions hosted by Dr. Paddy Finn, VIOTAS CEO & CTO. Together with industry experts, Paddy and guests analyse and discuss a wide variety of topics related to electricity, the energy landscape and what the future may look like.
