en.Wedoany.com Reported - H2PRO and Sun Systems Group have signed a Memorandum of Understanding to build a renewable hydrogen production plant in Tarragona, Spain, powered entirely by solar photovoltaic energy. The project will operate off-grid, a relatively rare model in the industry, and its promoters claim it will be the first such facility in Tarragona. By 2032, the plant's electrolysis capacity will reach 150 megawatts.
The project will be implemented in phases: starting with 25 MW of electrolysis capacity, producing approximately 1,250 tons of renewable hydrogen annually; expanding to 50 MW in the second phase; and ultimately reaching a total capacity of 150 MW from 2032 onwards. The energy to power the electrolyzers will come from a dedicated photovoltaic plant promoted by Sun Systems Group, with up to 220 MW of photovoltaic capacity planned for deployment near the project site.
The hydrogen produced will primarily supply the Tarragona chemical and petrochemical cluster—one of the largest in Southern Europe, meeting a significant portion of Spain's industrial hydrogen demand. In addition to direct industrial supply, the project also plans to inject part of the hydrogen into Enagás's natural gas transport network via blending, with adjustments to be made once the supporting infrastructure for this energy carrier is completed. Future connections to the Spanish hydrogen backbone network and the H2Med corridor (linking the Iberian Peninsula with European markets) are also included in the roadmap.
The production cost of renewable hydrogen remains a major challenge for the industry. Although the cost of solar power generation has dropped significantly in recent years, the cost advantage has not yet fully translated to green hydrogen due to the design characteristics of most electrolyzers requiring a constant power supply. The technology developed by H2PRO uses an electrolysis system that can adapt to the variability of renewable electricity, aiming to directly utilize solar power, reducing reliance on the grid and the need for backup systems.
The collaboration between the two parties was facilitated by Norgestion. H2PRO, founded on research from the Technion – Israel Institute of Technology, has raised nearly 100 million euros from international investors, with support from entities such as Breakthrough Energy, Temasek Holdings, ArcelorMittal, and Yara International. Sun Systems Group specializes in industrial photovoltaic project development, is active in Tarragona, and was recently recognized by the Tarragona Chemical Business Association for its quality and sustainability efforts.
