FUNDACION CIRCE CENTRO DE INVESTIGACION DE RECURSOS Y CONSUMOS ENERGETICOS

Their core work

CIRCE is a Spanish research centre in Zaragoza specializing in energy resources, energy efficiency, and the transition to low-carbon systems. They develop and demonstrate technologies for waste heat recovery, renewable energy integration, biomass valorization, and smart grid management across industrial and urban settings. Their work bridges the gap between laboratory research and market deployment, with strong expertise in industrial energy systems, circular economy applications in packaging and biorefining, and data-driven energy management. They also run capacity-building and training programmes for energy professionals across Europe.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), CIRCE focused heavily on waste heat recovery, industrial process control, energy efficiency in buildings, and biomass supply chains — classic applied energy R&D. From 2018 onward, their work shifted decisively toward grid flexibility, energy storage, power electronics, digital tools (blockchain, big data, AI), bioeconomy, and the concept of energy-positive districts. This evolution reflects a move from optimizing individual energy systems to orchestrating integrated, decarbonized energy ecosystems at district and regional scale.

CIRCE is moving toward integrated digital energy systems — expect future work combining AI, blockchain, and flexibility services for decarbonized districts and grids.

How they like to work

CIRCE balances leadership and partnership effectively: they coordinated 23 of 75 projects (31%), a high rate that shows they can build and manage consortia, not just contribute. With 1,007 unique consortium partners across 40 countries, they operate as a well-connected hub rather than staying within a fixed group of collaborators. Their strong presence in both Innovation Actions (35) and Coordination & Support Actions (24) indicates they are equally comfortable with technology demonstration and network-building roles.

CIRCE has collaborated with over 1,000 distinct partners across 40 countries, making them one of the most broadly networked energy research centres in Spain. Their reach spans all of Europe with no obvious geographic bias, reflecting their role as a go-to partner for pan-European energy and circular economy projects.

What sets them apart

CIRCE combines deep technical capability in energy systems with an unusual breadth across the entire energy value chain — from biomass supply logistics and industrial heat recovery to smart grid management and circular economy. Unlike university labs that stay theoretical, CIRCE's heavy involvement in Innovation Actions (47% of projects) means they deliver demonstration-ready solutions. Their cross-sector reach into food, agriculture, and manufacturing makes them a versatile consortium partner who can bridge energy technology with real industrial applications.

Highlights from their portfolio

• SHIP2FAIR
  Coordinated with EUR 1.4M funding — their largest coordinated project, targeting solar heat integration in agro-food industrial processes across multiple demonstration sites.
• CIRC-PACK
  Coordinated a circular economy project tackling the entire plastic packaging value chain from bio-based design to recycling and new business models — unusual cross-sector reach for an energy centre.
• MIGRATE
  Participated in a major EUR 921K project on massive integration of power electronic devices into European grids — reflects their growing role in grid-level energy system transformation.
