Navarre has identified the opportunity to position itself in a leading position in the development of the hydrogen economy. Its strategy is underpinned bya long tradition in renewables , which in itself makes the region one of the most dynamic in Spain in the energy transition. The region is making progress in the installation of new generation electrolysers, the promotion of industrial plants and integration in important energy corridors.
Previously, we have analysed cases of the advance of renewable hydrogen in autonomous communities such as Andalusia, Extremadura, Castile-La Mancha and the Basque Country. In this article, we will take a closer look at what Navarre is doing in this area.
In the last decade, Navarre has accelerated the deployment of an energy model marked by the transition towards clean energy generation. Analysing the mix in Navarre, the share of electricity produced in the region in 2025 is 70% green, compared with the national average of 56%.
The community’s industrial sector has made progress in energy efficiency measures, as well as in the adoption of photovoltaic self-consumption. More than 200 megawatts of wind and PV generation have been added. The question here is: what role does renewable hydrogen play in Navarre?
The reality is that green hydrogen or biomethane appear as future alternatives in a region that continues to advance in its decarbonisation. In this regard, institutional collaboration and integration in the country’s major infrastructure projects have become determining factors in making the leap.
Along these lines, the Government of Navarre and Enagás recently met to advance the implementation of green hydrogen in the region. At this meeting, President María Chivite, the Regional Minister for Industry, Ecological Transition and Digital Business, Mikel Irujo, and the CEO of Enagás, Arturo Gonzalo – accompanied by part of his management team – shared their plans to speed up the implementation of this energy.
Enagás has recently initiated the deployment of the Public Participation Concept Plan (PCPP) of the Hydrogen Backbone Network in Navarre. Thirty-seven kilometres of hydro-products will run through Navarre on the Haro-Zaragoza section, a strategic corridor that places the region as a possible aggregation node in Tudela Norte, where future projects for both generation and industrial demand will be concentrated.
The PCPP is collecting contributions from autonomous communities, city councils, public administration agencies, organisations and the general public with the aim of sharing information on the project, resolving doubts, mitigating territorial impacts and ensuring that the development of the Trunk Network meets appropriate social and environmental criteria from its initial phase. In total, the first phase of this network envisages the deployment of some 2,600 kilometres of hydroducts distributed over 15 sections and five major axes.
Since 2021, the Government of Navarre has had the Green Hydrogen Agenda, a plan that envisages the participation of the government authority, companies and research centres to consolidate an ecosystem favourable to innovation and the production of clean energy.
In this context, it is essential for Navarre to position itself as a key player in the new hydrogen economy. Hence, the company Nordex Electrolyzers, the result of a public-private partnership with the Navarre government, has designed and manufactured a 2.5 MW green hydrogen electrolyser in Navarre.
This development is significant precisely because of the modular and scalable design of these devices, which will allow them to be combined (e.g. up to four 2.5 MW modules) to achieve power outputs of 5 MW or even 10 MW. This is part of a strategy designed to position Navarre as a major industrial centre for hydrogen production in southern Europe from 2026.
Also, the consortium formed by Viscofan, Nordex Electrolyzers, AIN and the startup URAPHEX has successfully completed the start-up of the H2OP project, and has succeeded in initiating the production of green hydrogen at Viscofan’s facilities in Cáseda (Navarre). This pioneering initiative positions the consortium as a milestone in the application of renewable hydrogen to the decarbonisation of Navarre’s industry.
Thanks to the coordinated work of the four companies, the consortium has designed, installed and integrated in a record time of two months a 500 kW electrolyser, developed and manufactured entirely in Spain by Nordex Electrolyzers, together with the water treatment and recovery plant and its connection to the industrial boiler.
In addition, part of the impetus comes from European and national public funds: in 2025, the MITECO aid programme (through the RENOVAL programme) allocated Navarre more than 11 million euros to manufacture renewable technology equipment and components, including hydrogen electrolysers.
Navarre has consolidated its position as a trailblazer in green hydrogen innovation and development, thanks to the leadership of the National Renewable Energy Centre (CENER), which drives most of the research projects, and the presence of key companies in industrial and technological development.
In the business field, Nordex Electrolyzers is a major player with the NX2500 project, the first 2.5 MW green hydrogen electrolyser designed and manufactured entirely in Spain, and with H2OP, focused on the efficient production of green hydrogen and the decarbonisation of industrial processes, in collaboration with companies such as Viscofan. In addition, Acciona Energía and Plug Power are developing the Valle H2V Navarre Project, which envisages the construction of a 25 MW green hydrogen plant powered by hybrid renewable energy, mainly for the industrial sector.
Statkraft and Enhol are developing a green hydrogen plant in the Ciudad Agroalimentaria de Tudela, aimed at supplying the local agri-food complex.
This ecosystem of projects places Navarre in a prominent position on the national energy map, reinforcing its commitment to innovation, sustainability and the transition to a low-carbon economy.
In addition, there are some projects that deserve a mention. In this regard, the Valle H2V Navarre project, promoted by ACCIONA Energy and Plug Power, has set up an industrial-scale green hydrogen production plant in Sangüesa (Rocaforte) with a 25 MW electrolyser, supported by renewable energy from photovoltaic and wind power installations, with the IDAE “H2 Pioneers” grant.
The investment is around 87 million euros, and it is estimated that some 3,880 tonnes of green hydrogen will be produced per year, of which around 90% will be allocated for energy-intensive industries (paper, glass, steel, food, automotive, etc.) with the aim of helping them to decarbonise.
With electrolysers developed on its territory, industrial projects underway, infrastructure plans and an ambitious renewable gas strategy, the region is well positioned to face the energy transition. If the planned projects are completed and the commitment to innovation and investment continues, Navarre could make a name for itself in the renewable hydrogen economy.
