  • hydrogen storage and transmission on the Teréga grid to supply hydrogen to GazelEnergie’s renewable power plant,
  • renewable power production, 100% dispatchable, via a combined cycle power plant operated by

Lacq Hydrogen, submitted in response to the Call for Expressions of Interest for “INNOVATIVE PROJECTS OF A EUROPEAN OR NATIONAL SCALE ON THE DESIGN, PRODUCTION AND USE OF

HYDROGEN SYSTEMS” in June 2020, as an Important Project of Common European Interest (IPCEI), aims to become one of the European links in the strategic hydrogen value chain, driven by growing demand for green electricity.

Lacq Hydrogen is fully in phase with France’s stated ambitions for hydrogen: to build by 2030 a carbon-free, sustainable and international hydrogen sector; and those of the European Union: to produce 10 million tonnes of green hydrogen by 2030 at a competitive price.

Contributing to the carbon neutrality goals sets by the European Union and France, the Lacq Hydrogen project illustrates the ambitious initiatives deployed by industrial companies in favour of green energy.

“As a gas operator and accelerator of the energy transition, the promotion of new gases forms part of our absolute priorities. The cooperation with GazelEnergie, DH2 and Enagás is a major milestone in accelerating the mass development of green hydrogen for Europe and all the regions. We are proud to be contributing to managing this pioneering project within a sector which is making the news, which has a strong potential and which, we are convinced, has a great future. ” Dominique Mockly – Chairman and CEO of Teréga stated.

« Enagás’s roadmap, both in the short and long term, is aligned with the European hydrogen strategy and with the entire Spanish energy and climate strategic framework. TSOs, such as Enagás and Teréga, can play a key role in the European decarbonisation process, contributing their experience, know-how and capacity as a systems integrator. Spain is strongly positioned to become a producer and exporter of renewable hydrogen. The Spanish gas network is a crucial long-term infrastructure”. Marcelino Oreja – CEO of Enagás stated.

  “GazelEnergie is an energy producer and supplier activity involved in the energy transition. The deployment of innovative and renewable energies into the heart of the territories is a challenge that we wish to meet. The Lacq Hydrogen project, certainly ambitious, responds to these objectives, and thanks to the cooperation with Enagás, DH2 and Teréga, will enable us to deploy a dispatchable green energy solution.” Jean-Michel Mazalérat – Chairman & CEO of GazelEnergie stated.

  «Lacq Hydrogen is the perfect demonstration of the emerging role of green hydrogen as the cornerstone of fully dependable 100% renewable energy systems. At DH2 Energy we are proud to enable such a project with the very large volumes of competitively priced hydrogen supplied from our solar and electrolysis facilities in Spain.”» Thierry Lepercq, Chairman of DH2 Energy stated.

 Lacq Hydrogen: a first step in creating a European hydrogen backbone

 As an industrial project anchored in the territories, Lacq Hydrogen is part of the Spanish Green Crane project to produce and export renewable hydrogen from Spain. It is one of the first stages, that can be replicated, of building a European Hydrogen Backbone. This vision presented in July 2020 by Teréga, Enagás and 9 other European TSOs operating in nine member States foresees the gradual emergence of a European hydrogen network.

The aim is to deploy 6,800 km of pipelines by 2030 to connect the “hydrogen valleys” and 22,900 km of hydrogen networks across Europe by 2040, 75% of which will be converted natural gas pipelines, connected by new pipeline sections (25%).

Lacq Hydrogen: a sustainable and replicable model, at scale, of European cooperation to support a decarbonised industry



Lacq Hydrogen illustrates the synergies between Spanish and French industrial partners who want to build the sustainable energy models of tomorrow. Hydrogen will be produced by water electrolysis in Spain using solar power and at very competitive prices, thanks to the large solar resource in the region of Aragón. Transmission to the power plant will be provided by the Enagás and Teréga gas networks until hydrogen-dedicated infrastructure is developed. In addition, use of the Teréga aquifer storage is also being planned in order to obtain a 100% dispatchable power plant.

The project will supply a combined cycle power plant built and operated by GazelEnergie and located within the industrial area of Lacq. The plant will be supplied with hydrogen from 2026 and will produce 100% renewable energy, decarbonised and dispatchable, thus preventing the discharge of more than 700,000 tonnes of CO2 emissions per year.


Lacq Hydrogen: a key opportunity for the industrial revitalisation of the territories


A full part of the “HyDeal Ambition” initiative, Lacq Hydrogen, by teaming up with the suppliers of electrolysers, steel pipes and (hydrogen) gas turbines is an opportunity to support industrial relocation as well as boosting the territories by using French and European technology and innovation, thereby helping to secure thousands of jobs.

Lacq Hydrogen project could therefore create 1,200 permanent direct jobs over the entire chain. During the construction phase, an additional 1,000 jobs may also be created.


The project is being integrated into the “Territoires d’Industrie Lacq Pau Tarbes” initiative. It will thereby contribute to revitalising the Lacq industrial platform, in a decarbonised ecosystem, with high expertise over the entire value chain.
