The Aragon Hydrogen Foundation has hosted a final event in which the partners have evaluated the results achieved with the project and its possible applications.
Achieving the objectives set by the European Union in terms of emission reduction and climate neutrality makes it essential to act on various sectors, including industry.
The introduction of renewable energies in the energy mix requires the adoption of structural solutions in countries and makes it advisable to take advantage of energy vectors such as hydrogen, which can make a decisive contribution to achieving all these milestones. Green hydrogen can be produced using surplus renewable energies such as wind or solar energy, which cannot be introduced into the electricity grid due to technical limitations, and at a much lower cost than would be involved in extending the transport and distribution networks. It can also be stored for consumption when needed, overcoming one of the main limitations of renewable resources, and can be produced on a large scale through electrolysis if there is a sufficient supply of electricity from renewable sources.
Electrolysis is the most promising method for providing green hydrogen to the industrial, transport or energy sectors, but it has limitations such as high costs or reduced efficiency compared to other storage systems. However, it is possible to act on some of these costs and factors, as proposed by the OPTILYSER project, promoted by the Foundation for the Development of New Hydrogen Technologies in Aragon (Fundación Hidrógeno Aragón, AEI HA), with the University of Zaragoza, Inycom, SFICE Innovative Minds and Zoilo Ríos as partners. The Aragon Hydrogen Foundation hosted a final event in which all the partners were able to evaluate the results of the project and its possible applications.
The final objective of the OPTILYSER project is to design and validate an optimal electrolysis dispatch software for green hydrogen production that is valid for any technology, any use of the hydrogen produced and any type of electrical supply to the electrolyser.
To this end, three banks of electrolysers have been characterised with the most mature technologies (alkaline, PEM and AEM), connected to the grid and to a photovoltaic generation plant. In addition, predictive modules have been developed for electricity prices in the wholesale market and for the availability of renewable resources.
This project can help operators of hydrogen production plants to minimise their production costs for a given green hydrogen demand.
The OPTILYSER project has received funding from the Spanish Ministry of Industry, Trade and Tourism as part of the programme to support Innovative Business Groups (AEI) to contribute to improving the competitiveness of Spanish industry.
