CLEANCARB SARL

Their core work

CleanCarb is a Luxembourg-based technology SME specializing in advanced battery systems and thermal management for electric vehicles. They develop solutions spanning thermal comfort systems using Joule and Peltier effects, modular battery pack design and manufacturing, and self-healing polymer components for lithium-ion batteries. Their work sits at the intersection of materials science and automotive electrification, contributing specialized component-level expertise to larger European research and innovation consortia.

What they specialise in

How they've shifted over time

CleanCarb's trajectory shows a clear deepening into battery technology. Their early work (2015-2018) focused on thermal effects in electric vehicle comfort systems — managing heat via Joule and Peltier effects with insulation materials like PMMA. From 2017 onward, they shifted toward battery pack architecture itself (modular design, energy density, mechanical integration) and most recently into advanced battery materials — specifically self-healing polymers for lithium-ion cells. The arc moves from thermal management around batteries to the batteries themselves, and finally into the materials science that determines battery longevity.

CleanCarb is moving from system-level EV components toward advanced materials science for next-generation lithium-ion batteries, suggesting future work in battery durability and longevity.

How they like to work

CleanCarb operates exclusively as a consortium participant — they have never coordinated a project, which is typical for a specialized SME contributing targeted expertise to larger teams. With 39 unique partners across 11 countries from just 3 projects, they work in sizeable international consortia and appear comfortable integrating into diverse teams. Their consistent participant role suggests they are valued for specific technical contributions rather than project management capacity.

Despite only 3 projects, CleanCarb has built a broad network of 39 unique partners across 11 countries, indicating involvement in large, multi-partner consortia typical of transport and energy research. Their Luxembourg base and wide geographic spread suggest strong European integration without a single dominant national cluster.

What sets them apart

CleanCarb bridges an unusual gap between thermal engineering and battery materials science — few SMEs span both domains. Their progression from thermal management to self-healing battery polymers gives them cross-disciplinary insight into how heat, materials, and battery performance interact at the component level. For consortium builders, they offer a rare combination: a small, agile company with hands-on experience in both the thermal and electrochemical sides of EV battery systems.

Highlights from their portfolio
