The T-HYNET project is an initiative led by Repsol to build a 150 MW alkaline electrolyzer at the Tarragona Industrial Complex, capable of generating 2.7 tons of renewable hydrogen per hour and 21.4 tons of electrolytic oxygen.
It is estimated that it will be the largest electrolyzer in Spain, avoiding the emission of up to 200 kilotonnes of CO₂ per year, the equivalent of the energy consumption of more than 37,000 homes or the absorption capacity of 4 million trees.
Project details
The electrolyzer will be equipped with state-of-the-art technology that maximizes the energy efficiency of the process, using recovered industrial water. The renewable hydrogen produced will initially be used as a feedstock in local industrial processes, particularly in refining and chemical production.
One of the most relevant uses will be its incorporation in the production of e-methanol in the Ecoplanta Molecular Recycling Solution. In addition, T-HYNET contemplates applications in sustainable mobility T-HYNET also contemplates applications in sustainable mobility, aimed at heavy and collective transportation, opening the door to new energy vectors in the medium term.
Financing and territorial integration
The project has been selected by the Ministry for Ecological Transition and the Demographic Challenge as one of the strategic projects of the state program Hydrogen Valleys, within the Recovery, Transformation and Resilience Plan, financed by Next Generation EU funds. Thanks to this inclusion, the initiative has received public support of 104.19 million euros.
This funding allows to consolidate Tarragona as an energy pole within the Hydrogen Valley of Catalonia and the Ebro Hydrogen Corridor, two important ecosystems in the implementation of the hydrogen economy in southern Europe.
Next steps and start-up
T-HYNET is currently in the engineering phase and is scheduled for commissioning in 2028, when it will come into operation as the most powerful renewable hydrogen production infrastructure in the country. Its development is expected to consolidate Tarragona as a hub for the production of renewable fuels, such as methanol and green ammonia, contributing to energy independence and emissions reduction on a European scale.
