The latest episode of the Engineers Collective is out now: listen in on Spotify, Apple Podcasts or your usual platform. This month we’re joined by the International Hydropower Association (IHA) to discuss the “grandfather” of renewable energy. IHA senior energy policy manager Rebecca Ellis chats to NCE news editor Rob Hakimian about the history and importance of pumped storage hydro, covering how it works, its ability to “store” energy and why this is so crucial as the world transitions to a zero carbon energy system. Rebecca also tells us about the engineering and risks involved with developing pumped storage hydro schemes, talks about the appetite for pumped storage hydro projects in the UK and around the globe and highlights some of the exciting new schemes and technologies that are emerging in the sector. Prior to the interview portion, Rob is joined by NCE senior reporter Tom Pashby to discuss the potential impact of Hinkley Point C on fish populations in the Bristol Estuary and how a recent legal ruling could impact its plans, as well as the news that Liverpool City Region’s Mersey Tidal barrage scheme is moving forward.
