Hydrogen production & Distribution


Develop new storage material with high hydrogen storage capacity, able to be managed in real-time for a distributed level of applications, included on a specifically designed storage tank and interlinked to an energy provision system, which is able to match intermittent energy sources with local energy demand (buildings, small dwellings). The target for the materials and the overall system are indicated below:

- Hydrogen storage capacity: 4.0 wt.%

- Hydrogen density : 40 g/l

- Absorption heat recovery : 25%

- Hydrogen stored : 600g

- Desorption rate : 1,5g/min


Achievements to date

There is no achieved result [yet] due to the early start-up of the project. At the present date, partners have started collaboration through a series of technical meetings.

Sample materials from Matres have delivered to FBK, where the catalyst addition will take place. Contacts have established with a local supplier of SOFC systems, SOFC POWER, invited within the Technology Transfer Board of EDEN.

The project website is close to finalization. FBK has submitted a press release disseminated within National newspapers, presented on some TV channels (RAI 2, ADA Channel) and to Radio program (RADIO 2 – Miracolo Italiano).


The expected impact of EDEN will be: First, the creation of a new and very large market for electrical and thermal energy storages, down to the size of the individual household; Second, the application of innovative Mg-Based metal hydrides for off-grid solutions and portable devices (regenerative cycle), contributing technology advancement; and Third , the introduction of technology in stationary applications in line with the European Commission strategic plan for safe delivery of energy in cities and high populated areas.


EDen aims at building a forefront of scientific, technological and industrial expertise in energy storage and recovery systems. In the past years, hydrogen has been indicated to be an advantageous energy carrier, mainly in the field of environmental preservation and high energy density.

The necessity of hydrogen on specific mobile applications and energy backup systems is promoted by the growing demand of sustainable solutions and the interface of discontinuous renewable energies.

Hydrogen storage is well known as the major bottleneck for the use of H2 as an energy carrier and despite the huge scientific and industrial effort [fig.1] in developing a novel practical solution for the hydrogen storage,, there are very few storage systems available for nice markets.

The request for an energy storage system is growing as fast as the energy availability from renewable sources and consequently, the market is demanding more performing systems which are safer and more economically sound.

It has emerged from the past EU projects (STORHY, NESSHY, COSY, NANOHY, FLYHY) that hydrogen storage in solid state is the most palpable solution. Between the materials studied for solid state hydrogen storage, Magnesium based systems represent the most appealing candidate, able to meet the industrial storage targets – reason being that  they have proper gravimetric and energetic density (typical >7 wt. %, ≥ 100 kg H2/m3) and suitable charging and discharging times and pressures.

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, the EDen project aims to overtake these limitations by developing and realizing 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.
