The contract confirmed theconstruction of a 4.5 MWp solar power plant named PV3 (3rd photovoltaic – PV –field of the Spaceport) a key element in the project to supply low-carbonhydrogen for the spaceport.     Caption: Signature ceremony in the Jupiter Room at Europe’s Spaceport in French Guiana HYGUANE Hyguane, an acronym that stands for ‘Environmentally Neutral GuyaneseHydrogen’ is an ambitious project led by the European Space Agency (ESA) withFrench space agency CNES and industrial and academic partners to develop alow-carbon hydrogen ecosystem at the Europe’s Spaceport in French Guiana.Julia Talamoni, energy transition engineer for the Hyguane project, explains,“The Hyguane project aims to produce low-carbon hydrogen to fuel Ariane 6.Currently, the hydrogen in use is produced in French Guiana from methanolsteam reforming. This process produces high amounts of carbon and requiressignificant external heat and methanol, making the spaceport dependent onexternal supply. The Hyguane project is therefore part of a broader initiative toreduce the carbon footprint of space activities and works towards strengtheningthe sovereignty and autonomy of European access to space.” For a low-carbonwater electrolysis of hydrogen, the electricity used needs to come from arenewable energy source. “The installation of the PV3 solar farm provides a low-carbon power supply to the water electrolyser, leading to the production of a“low-carbon molecule”, explains Julia.The pilot scheme of Hyguane will aim to produce 10 to 15% of Ariane 6 hydrogenneeds per year. Beyond this, the Hyguane ecosystem will provide hydrogen tofuel heavy vehicles in French Guiana for regional mobility and to produceenergy through hydrogen fuel cells, including electrical back-up of criticalinfrastructure systems at Europe’s Spaceport in case of black-out.HYGUANE Low-carbon hydrogen by 2026. The Hyguane ecosystem will be completed with the construction of a hydrogenrefuelling station and, pending funding from ESA Member States, a garage tomaintain hydrogen-powered vehicles.Work has already begun on a water electrolysis plant and a hydrogenconditioning centre used to compress and prepare the produced hydrogen fortransport, with works on the other elements of the project due to start in 2026.According to Teddy Peponnet, ESA’s Head of the Hyguane project, “The fullHYGUANE ecosystem will be commissioned by the second half of 2027, signingthe first low-carbon hydrogen-fuelled Ariane 6 ready to fly.”   Hyguane, an acronym that stands for ‘Environmentally Neutral GuyaneseHydrogen’ is an ambitious project led by the European Space Agency (ESA) withFrench space agency CNES and industrial and academic partners to develop alow-carbon hydrogen ecosystem at the Europe’s Spaceport in French Guiana.Julia Talamoni, energy transition engineer for the Hyguane project, explains,“The Hyguane project aims to produce low-carbon hydrogen to fuel Ariane 6.Currently, the hydrogen in use is produced in French Guiana from methanolsteam reforming.
