CALDIC NEDERLAND BV

Their core work

Caldic Nederland BV is a Rotterdam-based private company that contributes industrial materials or specialty chemical expertise to thermal energy storage and heat battery projects for buildings. Their H2020 participation spans two projects focused on storing heat energy in compact systems for residential retrofitting and new heating installations, including integration with heat pumps and district heating networks. They bring the industrial supply or materials side to academic-led research consortia — translating advanced thermal storage concepts into components that can work in real social housing and private dwellings. Their involvement in both a research project (RIA) and a demonstration project (IA) shows they operate across the full technology readiness curve, from lab to market.

What they specialise in

How they've shifted over time

In their first project (CREATE, 2015), Caldic's involvement was in general compact thermal energy storage for retrofitting — a research-stage effort with no market-facing keywords attached. By 2019, their second project (HEAT-INSYDE) shows a clear pivot toward residential market application: keywords like social housing, privately owned dwellings, and demonstration signal a shift from laboratory R&D toward real-world deployment at scale. The move from a RIA funding scheme (CREATE) to an IA scheme (HEAT-INSYDE) confirms this trajectory — they are progressing from contributing to research toward contributing to commercialization.

Caldic is moving toward the commercial end of the thermal storage value chain, with increasing focus on deployable heat battery solutions for the residential building sector — a strong fit for future consortia targeting building decarbonization at scale.

How they like to work

Caldic has never led an H2020 project — they join as a participant in consortia led by others, likely contributing specialized materials, components, or industrial scale-up knowledge rather than scientific coordination. Despite only two projects, they have accumulated 32 unique partners across 10 countries, suggesting they are placed in large, multi-partner consortia where their industrial role complements academic and engineering partners. This profile points to a reliable, specialist partner rather than a project driver — valuable to consortium builders who need an industrial supply-chain actor to strengthen the market-readiness case.

With 32 unique consortium partners across 10 countries from just two projects, Caldic has a broad European reach relative to their project volume — averaging roughly 16 partners per project, which is typical of large IA and RIA consortia. Their Rotterdam base and Dutch registration suggest a natural pull toward Northern European heating markets, but the multi-country network indicates they are comfortable in pan-European project structures.

What sets them apart

Caldic's value to a consortium is that of a non-SME industrial company that can bridge materials or specialty chemical supply with energy storage system development — a profile that strengthens the commercial viability narrative that EU innovation projects need to score well. Based in Rotterdam, one of Europe's largest industrial hubs, they bring logistical and supply-chain credibility that purely academic or engineering partners cannot offer. For a building energy or district heating project seeking an industrial partner to anchor the exploitation plan, Caldic fits a gap that is often hard to fill.

Highlights from their portfolio

• HEAT-INSYDE
  Their most recent and market-facing project, running to 2025, with an Innovation Action designation and explicit targets for social housing and privately owned dwellings — the closest Caldic has come to commercializing thermal storage technology.
• CREATE
  Their first H2020 project (2015–2020) and their largest single EC contribution (EUR 227,000), establishing their entry into EU-funded thermal energy storage research for building retrofitting.
