Strengthening buildings, flexibility and cybersecurity in Europe’s energy system

In this episode of the EU Energy Projects Podcast, Areti Ntaradimou spoke with Leon Nielsen from CIRCE Technology Centre, a leading Spanish research and innovation organisation at the forefront of Europe’s energy transition. The conversation explored how policy, technology, and collaboration intersect to shape a more sustainable, flexible, and resilient energy system. Based in Zaragoza, CIRCE plays a crucial role in translating research into real-world solutions. As Nielsen explained, their work spans electricity production and storage, industrial decarbonisation, transport, digitalisation, and energy efficiency. They discussed three flagship initiatives that illustrate this approach. Project Chronicle, Reflex and EFORT.
