WILHELM ROSER SOHNE GMBH CO. KG

Their core work

Wilhelm Röser Söhne is a German specialty construction materials SME based in Neresheim, Baden-Württemberg, with apparent expertise in advanced cementitious and composite building materials. Their H2020 participation reveals a company that bridges traditional construction materials manufacturing with cutting-edge materials science — specifically applying nano-additives, graphene, and phase-change materials to building envelope systems. In the NRG-STORAGE project, they contributed to developing porous cementitious nanocomposites capable of storing and releasing thermal energy, integrating both active and passive building climate control strategies. Their real-world value is translating advanced material formulations into prototype building components that improve energy efficiency in non-residential construction.

What they specialise in

How they've shifted over time

In their first H2020 project (2015–2019), Wilhelm Röser Söhne participated in SUPERCONCRETE, a researcher mobility and education network around sustainable concrete modelling — a relatively foundational, research-facing role with no specific applied technology keywords. By 2020–2024, their focus shifted decisively toward applied energy materials: the NRG-STORAGE project brought a dense cluster of specific technology terms including bio-based PCM, ultra-lightweight cementitious foam, graphene, meta-materials, and building envelope integration. The trajectory is clear: from broad research participation toward specialized, application-ready thermal construction materials with direct commercial relevance.

This company is moving toward high-value niche materials for energy-efficient building envelopes — a segment growing rapidly with EU building renovation targets — making them a relevant partner for renovation, prefabrication, or smart building material projects through 2030.

How they like to work

Wilhelm Röser Söhne has participated exclusively as a consortium partner rather than a coordinator, suggesting they contribute specialist manufacturing or materials expertise rather than driving project strategy. Their two projects are very different in scale — a small MSCA-RISE grant and a substantial Innovation Action — indicating flexibility across project types. With 18 unique partners across 11 countries from just 2 projects, they are embedded in genuinely diverse consortia, which suggests they are sought out for a specific capability rather than bringing their own network.

Despite only two projects, Wilhelm Röser Söhne has built a surprisingly broad network of 18 unique partners spanning 11 countries, reflecting the large multi-partner consortia typical of MSCA-RISE and Innovation Actions. Their geographic spread implies European-level integration rather than a purely regional footprint.

What sets them apart

As a German industrial SME rather than a university or research institute, Wilhelm Röser Söhne offers something rare in H2020 consortia: a manufacturing-grounded perspective on advanced construction materials, capable of moving from lab-scale material formulations to prototype building components. Their combination of concrete technology heritage and uptake of graphene and bio-based PCM positions them at the intersection of traditional construction and smart materials — a gap few SMEs occupy. For consortium builders, they represent a credible industrialization partner who can validate whether a material concept is manufacturable at relevant scale.

Highlights from their portfolio

• NRG-STORAGE
  Their largest project by far (€707,528 EC funding), this Innovation Action targets a commercially significant problem — thermal energy storage in non-residential building envelopes — using a technically dense combination of graphene, bio-based PCM, and cementitious nanocomposites.
• SUPERCONCRETE
  Their entry into EU research via an MSCA-RISE network demonstrates early engagement with the international sustainable concrete community, which likely established the scientific relationships that led to NRG-STORAGE.
