Their core work

Sunlight Group is a Greek industrial company specializing in energy storage systems, particularly batteries and electrochemical storage technologies. They bring real-world manufacturing and deployment expertise to EU research projects focused on smart grid integration, demand response, and battery materials characterization. Their contributions span from factory-floor automation and augmented working environments to grid-scale flexibility solutions involving power-to-heat and power-to-cold technologies. As a large private company (not an SME), they serve as an industrial end-user and technology validator in research consortia.

What they specialise in

How they've shifted over time

Sunlight Group's H2020 trajectory shows a clear shift from applied grid solutions toward deeper materials science and storage technology development. Their early projects (2015–2017) focused on factory automation (SatisFactory) and smart grid management with demand response optimization (inteGRIDy). By 2019, their focus moved downstream to battery materials — characterization, safety, and electrochemical storage testing (TEESMAT) — while also expanding into flexible energy systems combining batteries with power-to-heat/cold (X-FLEX). This signals a company moving from being a grid-integration partner to positioning itself at the core of the energy storage value chain.

Sunlight Group is deepening its focus on battery technology fundamentals — materials testing, safety, and multi-vector flexibility — suggesting they are building capabilities for next-generation energy storage products.

How they like to work

Sunlight Group participates exclusively as a consortium partner, never as coordinator, across all four H2020 projects. With 82 unique partners across 19 countries, they operate in large, diverse consortia typical of Innovation Action (IA) projects. This pattern indicates a company that contributes industrial expertise and real-world validation rather than driving the research agenda — a reliable industrial partner that brings manufacturing reality to research-heavy teams.

Sunlight Group has built a broad European network spanning 82 unique partners across 19 countries through just 4 projects, reflecting participation in large IA consortia. Their reach is genuinely pan-European with no visible concentration in a single region.

What sets them apart

Sunlight Group stands out as one of the few large Greek industrial companies active in both energy storage manufacturing and EU-funded R&D on battery technologies. Unlike research institutes that study batteries theoretically, they bring a manufacturer's perspective — factory processes, material testing at production scale, and real grid deployment experience. For consortium builders, they offer a rare combination: an industrial energy storage company willing to validate and test research outputs in operational settings.

Highlights from their portfolio

• inteGRIDy
  Their largest funded project (EUR 371,875), covering smart grid optimization across energy distribution, utilization, and storage — their most comprehensive grid integration effort.
• TEESMAT
  An open innovation test bed for electrochemical energy storage materials, marking Sunlight's strategic move into battery materials science and characterization.
• X-FLEX
  Combines battery storage with power-to-heat/cold for grid flexibility, representing their most recent and forward-looking energy systems work.
