Improvements to Integrate High Pressure Alkaline Electrolysers for Electricity/H2 production from Renewable Energies to Balance the Grid
September 2011 - December 2014


ELYGRID Project aims at contributing to the reduction of the total cost of hydrogen produced via electrolysis couple to Renewable Energy Sources, mainly wind turbines, and focusing on mega watt size electrolyzes (from 0,5 MW and up). The objectives are to improve the efficiency related to complete system by 20 % (10 % related to the stack, and 10 % electrical conversion) and to reduce costs by 25%. The work will be structured in 3 different parts, namely: cells improvements, power electronics, and balance of plant (BOP). Two scalable prototype electrolyzers will be tested in facilities which allows feeding with renewable energies (photovoltaic and wind).


The Foundation for the Development of New Hydrogen Technologies in Aragon coordinates the ELYGRID project, managing the resources and interactions between consortium members to achieve the compliance of the goals of the project. The Foundation is in charge of the Balance of Plant redesign for a MW electrolyser,  integration of all the equipment, design and detail engineering works, leading the work package devoted to the balance of plant, looking for a minimization of costs and its optimal operation. Besides, it carries out the testing at industrial scale coupled to renewable energy sources and the dissemination of project’s results.
