A team of CSIC researchers develop the first public service hydrogeneration plant in Spain that will use green hydrogen generated on-site with solar energy. Hydrogen will be obtained by electrolysers powered by a system of solar trackers and photovoltaic panels located at the service station itself. In addition, it will have an intelligent control system that will provide production and demand predictions. The hydropower plant will have a minimum renewable production capacity of 60 kg of hydrogen per day. It will be able to supply trucks, buses, cars and warehouses and logistics for transport and is scheduled to start up at the end of 2022.

The new technology, which will be launched at the end of 2022, has photovoltaic panels to power the electrolyzers that obtain hydrogen from water.

The new technology will be tested thanks to an agreement with the station company. Zoilo Ríos service. It will be tested at the company’s facilities at the El Cisne service station, on the A-2 motorway (Madrid-Barcelona), a few kilometers from Zaragoza.

The objective of this development is to demonstrate, in real service conditions, the potential of this technology”, Explains CSIC researcher Luis Valiño, from the Laboratory for Research in Fluid Dynamics and Combustion Technologies (LIFTEC), currently part of the Institute of Carbochemistry (ICB). The new hydrogenerator will have the addition of technology developed by research groups from LIFTEC and the Institute of Robotics and Industrial Informatics (IRI, CSIC-UPC).

This new hydrogenerator offers several advantages: it will have an intelligent control system to coordinate its operation and it will provide modularity and flexibility.”, Details Valiño, the researcher in charge of the project, who has the collaboration of the researcher María Serra, from the Institute of Robotics and Industrial Informatics (IRI, CSIC-UPC).

The intelligent control system will provide production and demand predictions“Says Valiño. “It will include meteorological calculations that will make it possible to predict the irradiation of solar energy at 48/72 hours view and artificial intelligence algorithms to optimize the system economically and energetically. The entire system will be remotely controllable over the internet“, Add.

A technology adaptable to environments and demands

Being modular and flexible, the hydrogeneration will allow adapting to different demands (vehicle flow, hourly distribution …), to different locations (availability of renewable resources, network connection, connection power). “The objective is that, after the demonstration phase, the technology is marketable and has a broad market penetration“, Points out Valiño.

This initiative aims to serve as a model for the implementation of the future network of hydrogenerators in Spain. This collaboration between the CSIC and the company Zoilo Ríos will take place over three years (until December 2024) and will allow the CSIC research groups to evaluate the operation of the different technologies that will be used in the installation, both in terms of regarding the generation of renewable H2 as storage, advanced energy management and dispensing.

For its part, the company will be responsible for the tasks of adapting the service station and the administrative processing required for the installation, as well as providing the necessary resources for the operation of the hydrogenerator during the start-up and demonstration phase. , and will also take care of maintenance. Once the project is finished, the agreement contemplates the transfer of the technology developed to Grupo Zoilo Ríos through an exclusive exploitation license.

The development of this hydrogeneration is part of the action plan of the TransEner Interdisciplinary Thematic Platform, recently created by the CSIC, which conducts research aimed at improving the generation of renewable energy, its storage and logistics and distribution problems, with the help of European funds from the Recovery, Transformation and Resilience Plan.
