Elyse Energy: A new stakeholder in the decarbonized maritime industry in Saint-Nazaire
Decarbonizing the sectors most reliant on fossil fuels through the production of low-carbon molecules—that is the ambition of Elyse Energy. Based in Lyon, the company is a pioneer in its field. Since its creation in 2020, it has been developing production units for low-carbon molecules, primarily fuels, destined for maritime and air transport, as well as the chemical industry, where they are used as base components.
An e-methanol production unit, in partnership with Lhyfe
Established in France, Spain, and Portugal, Elyse Energy is expanding to Saint-Nazaire as part of the development of a green hydrogen production site in the Montoir-de-Bretagne port area. The project was awarded to hydrogen leader Lhyfe following a call for tenders by the Grand Port Maritime Nantes Saint-Nazaire. Lhyfe and Elyse Energy have partnered to produce 150,000 tonnes of e-methanol per year from green hydrogen.
Multiple industrial decarbonization projects underway
This young SME is already leading major projects, notably in the Rhône Valley, the Pyrénées-Atlantiques, and Spain.
“These projects are part of a national decarbonization strategy, which includes the development of technical and technological solutions,” explains Mathieu Hoyer, Director of Development. “They provide France with the means to decarbonize the most challenging sectors—those where alternatives are still limited—and contribute to energy sovereignty by producing molecules locally.”
Joining the decarbonization ecosystem in Saint-Nazaire
Elyse Energy is positioning itself within Saint-Nazaire’s strong momentum toward maritime economic decarbonization.
“We’ll also be able to rely on CO₂—another component of methanol—valorized through projects like GO CO₂, which plans to capture and transport the gas from major industrial emitters along the Atlantic coast, particularly cement plants, to the Saint-Nazaire area.”
Olivier Cuny, Elyse Energy’s representative in Saint-Nazaire
As Business Manager for the Northwest region, Olivier Cuny settled this summer at the Maison de l’Entreprise in Saint-Nazaire, supported by Nantes Saint-Nazaire Développement.
“I am proud to take part in an ambitious maritime transport decarbonization project, rooted in its territory, with one of the first ports in Europe to commit to providing alternative fuels.”
