How to combine innovation and energy and ecological transition?

OliKrom puts its expertise at the service of the environmental transition

Like the chameleon that can change colour to camouflage itself, coatings that adapt to their environment offer real opportunities to meet future environmental challenges.

For over seven years, OliKrom has been designing and producing intelligent colour-changing materials. “Our team programs colour changes to create indicators of safety, compliance, or authenticity for all sectors of activity. But in addition to this, we are particularly interested in the challenges of the ecological and energy transition by participating in the creation of a sustainable ecosystem,” emphasises Jean-François Létard, founding president of OliKrom.

The creation of an eco-sustainable road marking

This desire to create innovative solutions that respect the environment took concrete form in 2018 with the development and marketing of LuminoKrom® photoluminescent road markings as a replacement for public lighting, a technology with very low environmental impact. Today, more than 60 local authorities throughout France have deployed this innovation to make night-time travel safer. The first projects outside France have also met with great success (Canada, Nigeria, Belgium, Luxembourg, etc.).

Helping to create future eco-responsible solutions

OliKrom’s R&D department works daily on innovative developments, particularly around green hydrogen. In order to accompany the deployment of this future green fuel, one of the challenges taken up by our teams is the design of coatings capable of changing colour in the event of a hydrogen leak.

A major research effort is also dedicated to developing a reactive coating to combat heat islands in urban areas. Indeed, under the combined effect of increasing urbanisation and global warming, urban heat islands could become more intense. Adaptation and mitigation measures must be taken, a battle in which OliKrom is involved.

OliKrom’s voluntary positioning welcomed by Bpifrancee

As an SME committed to the ecological transition, OliKrom has become an ambassador of the Coq Vert community. 


In May 2021, the company joined other entrepreneurs committed to the fight against global warming and the environmental transition

Bpifrance supports companies in adopting more responsible behaviour in favour of the environment. Launched in partnership with ADEME and the Ministry of Ecological Transition, the Coq Vert community aims to create a collective emulation in favour of sustainable development.

Also a member of Bpifrance’s “Les Excellence” community, OliKrom has been suppo rted by Bpifrance since its creation in order to develop its research into a real commercial activity. “Bpifrance has followed us through each stage, focusing on the economic development that could lie behind all these research issues. This has led to job creation, but also to the creation of value, with the possibility of having a real impact on society,” explains Jean-François Létard.
