In this episode of the EU Energy Projects Podcast, Angelina Broukou of the Horizon Europe-funded SINNOGENES project, offers a timely reminder that while storage technologies themselves are not new, the way we deploy and integrate them is where the real challenge, and opportunity, lies.

“Storage is what makes renewables reliable and usable at scale,” Angelina explains. It is a simple statement, but one that captures a growing reality: without storage, the variability of renewables risks becoming a structural limitation rather than a manageable feature of the system.

Yet SINNOGENES does not focus on a single technology. Instead, it brings together batteries, thermal storage, hydrogen and even flywheels, connecting them through a digital layer and testing them across six real-life pilots in Europe. From industrial sites in Portugal and Germany to microgrids in Spain and island systems such as Ikaria in Greece, the project moves beyond theory to explore how these solutions perform in practice.
