Energy Transition: NaTran selects startups for its Nova incubator program

NaTran has announced the selection of three startups to benefit from a year of support, starting in February 2026, within the Nova incubator located on the site of the NaTran R&I research center in Villeneuve-la-Garenne (Hauts-de-Seine).

As part of its fourth call for applications, NaTran has selected KAYYA, Quiet Bioenergy, and Exanodia. They will benefit from the company’s Nova incubator program.

NaTran is continuing its industrial, technological, and digital transformation as part of its commitment to the energy transition.

To support this evolution, the company launched a call for applications between July and October for the 4th cohort of its Nova incubator, aiming to accelerate the development of innovative startups in the energy and digital transition sector while fostering synergies with industry.

Among the many applications received, three promising start-ups were selected:

• KAYYA specializes in methanization: it has developed a pre-treatment technology for “inputs” (organic matter) using micro and macro-organisms, improving their methanogenic potential and biomethane production yields.
• Quiet Bioenergy is a startup that also operates in the methanization sector. Its technology also increases biomethane production yields thanks to a molecule that accelerates energy transfers within methanizers.
• Exanodia is a start-up specializing in the development of software based on artificial intelligence for the analysis of inspection data and non-destructive testing (NDT) of industrial structures and equipment (radiography, ultrasound, magnetic particle testing, etc.).

The three start-ups will be hosted from February 2026 at the NaTran R&I research and innovation center. For one year, they will have shared workspaces on the premises and benefit from access to laboratories and support from researchers.

The selected start-ups can thus launch experiments supported by NaTran and capitalize on synergies with other members of the cohort.

The Nova incubator also offers them tailored technical, methodological, and entrepreneurial support (market research, economic studies, property expertise, intellectual property, networking with investment funds…), organizes Proof of Concept (POC) tests of their technologies at our research facilities or helps them carry them out at one of our partners’ sites. These POCs contribute to their visibility and
industrial development.

The launch of the 4th promotion took place on February 11th at the NaTran R&I premises in Villeneuve-la-Garenne.

The areas of activity of the startups in the Nova incubator reflect the priorities set by NaTran2030, namely:

• Accelerate the growth of renewable gases (biomethane, pyrogasification, natural gas)
• Transporting hydrogen and CO2 under optimal safety and conditions
  Adapting the network to new uses (flexibility, digital…).

“The energy transition raises many challenges: through the Nova incubator, we aim to encourage innovations that address them, echoing our NaTran2030 corporate project. We are delighted to be able to support KAYYA, Quiet Bioenergy, and Exanodia in the coming year. All three can count on the commitment, dynamism, and expertise of our teams to continue their development, ” says Pierre Blouet, Director of NaTran R&I.

“Incubation at Nova gives us access to the recognized expertise of NaTran R&I researchers in methanization processes. On the technical and economic fronts, it will allow us to validate our business model in preparation for our first fundraising round,” explains Ilan Palacci, co-founder of Quiet Bioenergy.

Houcine Mansour, president of Exanodia, states: “What NaTran brings us today is privileged access to its network of internal experts, its testing facilities, and its data, which will allow us to train robust and high-performance models based on real-world industrial data. NaTran also opens the doors to its ecosystem, both industrial and institutional, which is a major asset, particularly with regard to our future fundraising.”

“In the NaTran R&I laboratories, which we have just visited, we will be able to benefit from cutting-edge skills and testing resources in the field of biogas quality and its compatibility with transport and distribution infrastructures.

“This work, carried out with the expertise of the NaTran teams, will allow us to demonstrate the relevance of our solution,” says Vinciane Dubost, co-founder of KAYYA.

KAYYA, Quiet Bionenergy, and Exanodia are added to the list of 11 start-ups that have already benefited from the support offered by NaTran via its Nova incubator: LC-Engineering, Octométha, and Rift in 2025, SeADvance, Mirega, Revcoo, and Safehear in 2024, and Lium, Alhoma Systems, Ylssen, and Lynx for the 2023 cohort.
