The growth of energy storage seems unstoppable

Charge when it’s cheap, when energy is abundant, and discharge when the energy is needed.

The role of energy storage will be critical to the transition to low-carbon technologies. It’s an exciting time in the industry, with spectacular growth in battery storage markets in the US and around the world, and it’s predicted to continue. “We’re in the hockey stick growth phase,” says Swetha Sundaram, VP of solar and BESS (battery energy storage systems) at RWE, and a co-author of ‘The BESS Book’. She joins Ed Crooks on the show to look at where that growth is coming from.

The systems being built today mostly use lithium-ion technologies to store energy for a few hours. But there are huge opportunities for long-duration energy storage (LDES), too. The LDES Council, an industry group, estimates that the build-out of up to 8 TW of potential power supply from long-duration storage by 2040 represents a US$4 trillion investment opportunity. Julia Souder is CEO of the LDES council, and she’s also on the show to talk about the next generation of storage.

Julia, Swetha and Ed are also joined by Energy Gang regular Melissa Lott, a Partner General Manager at Microsoft. She’s a PhD energy systems engineer, and she explains the different roles short and long-duration energy storage will have in the energy transition and the power grid of the future.

Let us know what you think. We’re on X, at @theenergygang. Make sure you’re following the show so you don’t miss an episode – we’ll be back in two weeks, Tuesday morning at 7am eastern time.
