EDEN aims at building a forefront scientific, technological and industrial expertise in energy storage and recovery system. In the past years, hydrogen has been indicated as an advantageous energy carrier under many points of view, mainly environment preservation and high energy density. The necessity of hydrogen on specific mobile applications and energy backup system is promoted by the growing demand of sustainable solutions and the interface of discontinuous renewable energies. Hydrogen storage is well known to be the major bottleneck for the use of H2 as energy carrier and despite the huge scientific and industrial effort in developing a novel practical solution for the hydrogen storage, actually there are few storage systems available for nice markets. The request for energy storage systems is growing as fast as the energy availability from renewable sources, consequently the market is demanding for more performing systems, safer and economic. It is emerged from the past EU projects (STORHY, NESSHY, COSY, NANOHY, FLYHY) that the hydrogen storage in solid state is the better solution to seek.

Between the materials studied for solid state hydrogen storage, Magnesium based systems represent nowadays the major candidate able to meet the industrial storage targets: they have proper gravimetric and energetic density (typical >7 wt. %, ≥ 100 kg H2/m3) and suitable charging and discharging time and pressure. The main barrier to the wide use of the Magnesium based materials in hydrogen storage system is represented by two limitations: the working temperature of about 300°C and the high heat of reaction, around 10Wh/g. More specifically, EDEN project aims to overtake these limitations by developing and realising an efficient hydrogen storage system that brings together available solutions from the market, the results of the EU projects on hydrogen storage and the development of novel solution for the storing material.

  • Delivering energy to buildings, small dwellings and micro-communities by integrating intermitted thermal and electrical power sources with hydrogen storage systems;
  • Mitigating the problem of intermittent energy delivered to electricity grid. Higher storage capacity at the local level reduces the need to expand the grid;
  • Providing safe, reliable and high-density energy storage for domestic applications. Mg-based metal hydrides can configure as a safe material and technology, with high energy density (more than 2000 Wh/l);
  • Provide a viable complete system for hydrogen storage that will compete with the storage systems now available on the market.

Unit role: 

ARES is coordinator of the research project, from overall management  to dissemination and exploitation activities.
In collaboration with colleagues of the FMPS research unit of the Center for Materials and Microsystems (CMM-FBK), the ARES team is involved in work plans regardings the study, development, production and characterization of the functionalized materials for hydrogen storage, the design and modeling of the hydrogen tank and the design, control and analysis of the entire storage system under real working conditions.
