The collaboration between RPow and H2B2 Electrolysis Technologies has resulted in a renewable energy sources project, after announcing the construction of a hydrogen production plant and thermal energy storage in Andalusia, Spain.
The objectives of the “H2-24/7” hydrogen project
The project will be entitled: “Design and fabrication of alkaline electrolyzer with improved flexibility to adapt to direct connection to wind farms/photovoltaic plants to aim for the most competitive LCOH hydrogen levelized cost (H2-24/7)”, and has been received the endorsement of the Institute for Energy Diversification and Saving (IDAE). This support materialized with the final resolution of Program 4 H2 Value Chain, published last August 2, which grants a subsidy of 2.66 million euros for the construction of the plant in Seville.
This project is based on the use of a high-temperature electrolysis process, which makes it possible to produce hydrogen 24 hours a day and continuously. This is made possible by means of advanced SOEL electrolyzer technology, which operates at high efficiency. The system integrates the thermal energy storage with hydrogen generation, using a method involving molten salts to manage both the thermal and electrical energy required by the electrolyzer.
From a strategic point of view, this project drives the transition to a hydrogen-based economy by maximizing production from renewable energies such as photovoltaic and wind power. The implementation of more efficient electrolyzers adapted to new industrial applications will enable RPow and H2B2 to strengthen their position in the competitive renewable hydrogen market by outperforming their competitors with innovative technologies.
The potential of a hydrogen production plant
The purpose of the H2-24/7 project is to optimize the use of the electrolyzer, extending its operation to more hours per day and, as a consequence, increasing hydrogen production. RPow’s general manager, César Martín-Montalvo, explained the importance of the thermal storage system, which, in addition to providing electricity through a turbine, generates the heat necessary for the electrolysis process, a feature of the plant.
The development of a 100 kW electrolyzer with an efficiency of 39 kWh/kg will also be carried out, which is aligned with the objectives established by the European Union, within the framework of the Strategic Research and Innovation Agenda(SRIA) promoted by the Clean Hydrogen Partnership. H2B2’s CTO, Javier Brey, mentioned that this advance is vital for the fulfillment of European goals in hydrogen production.
