IKN GMBH INGENIEURBURO-KUHLERBAU-NEUSTADT

Their core work

IKN GmbH is a German engineering company specializing in equipment and process engineering for the cement and lime industries. Their company name — Ingenieurbüro Kühlerbau Neustadt (Engineering Office for Cooler Construction) — points to their core business: designing and building industrial coolers and kiln components for clinker production. Within H2020, they contribute deep process engineering expertise to projects that integrate CO2 capture technologies directly into cement manufacturing lines, bridging the gap between carbon capture R&D and real-world industrial deployment.

What they specialise in

How they've shifted over time

IKN's trajectory shows a clear progression from research to demonstration in cement decarbonization. Their earliest project, CEMCAP (2015-2018), explored CO2 capture concepts for cement plants broadly, while CLEANKER (2017-2023) narrowed the focus to a specific technology — calcium looping. Their most recent project, LEILAC2 (2020-2026), moves firmly into demonstration-scale deployment with a broader CCUS vocabulary including CO2 hubs and industrial use of captured carbon. This is a textbook research-to-deployment pipeline within one very specific niche.

IKN is moving from research participation toward demonstration-scale carbon capture integration in cement plants, positioning them as a key industrial partner for any consortium bringing CCUS from pilot to full deployment.

How they like to work

IKN participates exclusively as a consortium partner, never as coordinator — consistent with their role as a specialized industrial equipment provider contributing engineering know-how rather than leading research agendas. With 40 unique partners across 17 countries from just 3 projects, they operate in large, international consortia typical of major EU energy and industrial decarbonization initiatives. This suggests they are valued for their specific industrial capability rather than research leadership, making them a reliable technical partner who brings real plant-level expertise to academic-heavy consortia.

Despite only 3 projects, IKN has built a network spanning 40 partners across 17 countries — a result of participating in large-scale industrial decarbonization consortia. Their network is heavily European, concentrated in the cement and carbon capture research community.

What sets them apart

IKN occupies a rare niche: they are not a university, not a research institute, but an actual cement industry engineering firm sitting inside carbon capture research consortia. This gives them credibility that pure researchers lack — they know how cement plants are built, what equipment modifications are feasible, and what operational constraints real plants face. For any consortium working on industrial decarbonization of cement or lime, IKN provides the essential link between laboratory concepts and factory floor reality.

Highlights from their portfolio

• LEILAC2
  Their largest and most recent project (EUR 2M), moving CO2 capture for cement to full demonstration scale — a critical step toward commercial deployment.
• CLEANKER
  Highest single funding (EUR 2.5M) and focused on calcium looping, a promising capture technology that IKN helped validate at industrial conditions.
• CEMCAP
  Their entry point into H2020 carbon capture research, establishing IKN as an industrial voice in the cement decarbonization community.
