The EU Energy Projects Podcast

In the latest episode of the EU Energy Projects Podcast, Areti Ntaradimou is joined by Hugo Morais from the INESC ID cluster, representing three EU-funded projects: SHIFT2DC, U2Demo and EV4EU. 

While the projects focus on different parts of the energy system, they share a common ambition: to support electrification, increase flexibility and make energy assets more visible, controllable and useful for the grid.

SHIFT2DC explores the potential of direct current solutions in buildings, data centres, industry and ports. The logic is simple but powerful: many of the technologies we use today, from PV panels and batteries to EV chargers and servers, already operate in DC. Reducing unnecessary conversions could therefore improve efficiency and support decarbonisation.

U2Demo focuses on energy communities and real-life demonstrations. Here, the challenge is not only technical. As Hugo explains, integrating heterogeneous systems is difficult, but regulation can be just as complex. Different countries have different rules on governance, for example or in sharing flexibility services, which means tools often need to be adapted country by country.

EV4EU, which is approaching its conclusion, brings the electric mobility angle. Among its key results is a prototype bidirectional charging station using CCS technology, as well as open source tools for charging point operators. Yet the conversation also makes clear that electric vehicles will only become real flexibility assets if users are engaged, infrastructure is ready, and business models properly reward participation.

What stands out in this discussion is that digitalisation is not just a nice addition. Without data, there is no control; without control, there is no intelligence; and without intelligence, the benefits remain limited.

In the latest episode of the EU Energy Projects Podcast, Areti Ntaradimou had a discussion with Vasilis Kotrogiannis, representing the Smart Energy Cluster, about why clusters like this may be more valuable than they first appear.

The Smart Energy Cluster already brings together 39 ongoing projects and its mission is simple: help EU-funded initiatives cooperate, share results, and avoid working in isolation.

That may sound obvious. Yet in practice, many projects still operate in parallel, each running their own dissemination plans, events, newsletters and stakeholder outreach. Necessary work, yes, but often repetitive.

This is where clusters can make a real difference.

According to Vasilis, members gain access to joint events, collaboration workshops, networking opportunities and shared visibility through the cluster’s channels. More importantly, they can exchange technical know-how, discuss replication pathways, and build partnerships beyond the usual communication exercise.

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.

In the latest episode of the EU Energy Projects Podcast, the spotlight turns to one of the most critical—and often overlooked—pillars of Europe’s clean energy transition: buildings.

Recorded in the context of Enlit Europe 2025 in Bilbao, this episode follows the session “Flexible Solutions Empowering Citizens” and explores how thermal energy storage and digital integration can unlock flexibility at the local level. Joining the discussion are Emilia Pisani and Guillermo Andrés Nieto, representing the Thermal Energy Storage Cluster (TES Cluster), a collaboration of four Horizon Europe projects: THUMBS UP, ECHO, BEST Storage and Hi-Store.

Katrin Stökle, project manager at Steinbeis Europa Sentrum, discusses how the Steinbeis project cluster is approaching the decarbonisation of energy intensive industries.

Five diverse projects – of which four are active and one completed – comprise the Steinbeis energy cluster, with the common goal of decarbonising and advancing the energy transition of energy intensive processes in various industries.

These are H2GLASS and MOST-H2 focussed on how hydrogen can be used in industrial processes in the glass and transport sectors and COREu and CAPTUS focussed on carbon capture, use and storage in sectors such as steel, cement and chemicals. The completed project is FLEX4FACT, which focussed on the use of flexibility in industry through enabling production processes to adapt dynamically to renewable energy availability.
