HRS IS PART OF A REFUELING OPERATION AT THE HYMPULSION STATION IN SAINT-EXUPÉRY (FRANCE) AS PART OF THE PROGRAMME LED BY ALLDIS-NERIUS IN FRENCH GUIANA

Grenoble, June 23 2026 - HRS, French designer and manufacturer, European leader in hydrogen refueling stations, announces that, as part of the upcoming installation[1] of an HRS14 station at the Kourou Space Centre (French Guiana) and the promotion of hydrogen as a green energy source at the site, a demonstration of refuelling a 350-bar HYLIKO truck bearing the colours of the ESA (European Space Agency), the CNES (French National Centre for Space Studies) and MT-Aerospace will take place on Wednesday 24 June 2026 from the HRS40 station installed in July 2025 by HRS for HYmpulsion in Saint-Exupéry (Auvergne-Rhône-Alpes).

This event follows an order placed with HRS in December 2024 by ALLDIS-NERIUS, the company responsible for installing the hydrogen refueling station and commissioned by the ESA as part of the HYGUANE (Guyanese Hydrogen for Environmental Neutrality) project in Kourou. This station is designed to stimulate the development of hydrogen-powered heavy-duty vehicles with the aim of kickstarting the low-carbon transition of transportation in French Guiana.

The refueling of this truck will provide an opportunity to promote the deployment of a hydrogen ecosystem at the Kourou spaceport and to highlight the hydrogen industry stakeholders in Auvergne-Rhône-Alpes (France).
