New HyCARE scientific paper just released!

HyCARE’s researchers of the University Of Turin  (Italy), the Centre National de la Recherche Scientifique (France), the Helmholtz-Zentrum hereon GmbH (Germany), together with the Institute for Energy Technology (Norway) published the results of the analysis of neutron diffraction data.


Hydrogen is an efficient energy carrier that can be produced from renewable sources, enabling the transition towards CO2-free energy. Hydrogen can be stored for a long period in the solid-state, with suitable alloys. Ti-rich TiFe0.90 compound exhibits a mild activation process for the first hydrogenation, and Ti(Fe,Mn)0.90 substituted alloys can lead to the fine tuning of equilibrium pressure as a function of the final application. In this study, the crystal structure of TiFe(0.90-x)Mnx alloys (x = 0, 0.05 and 0.10) and their deuterides has been determined by in-situ neutron diffraction, while recording Pressure-Composition Isotherms at room temperature. The investigation aims at analysing the influence of Mn for Fe substitution in Ti-rich Ti(Fe,Mn)0.90 alloys on structural properties during reversible deuterium loading, which is still unsolved and seldom explored. After activation, samples have been transferred into custom-made stainless-steel and aluminium alloy cells used for in-situ neutron diffraction experiments during deuterium loading at ILL and ISIS neutron facilities, respectively. The study enables remarkable understanding on hydrogen storage, basic structural knowledge, and support to the industrial application of TiFe-type alloys for integrated hydrogen tank in energy storage systems by determining the volume expansion during deuteration. Furthermore, the study demonstrates that different contents of Mn do not significantly change the volumetric expansion during phase transitions, affecting only the deuterium content for the γ phase and the cell evolution for the β phase. The study confirms that the deuterated structures of the γ phase upon absorption, β and α phase upon desorption, correspond to S.G. Cmmm, P2221 and Pm-3m, respectively.

HyCARE Master Student receives the “German Renewables Award 2022”

On the 24th of August 2022, the official cerimony of the German Renewables Award took place at Altonaer Kaispeicher in Hamburg (Germany).

The initiative of the Renewable Energy Cluster Agency (EEHH) aims to “honour individuals and companies who are advancing the energy transition with novel products and projects”. The awards are presented annually in several categories: Project of the Year, Product Innovation, Student Work, Hydrogen Innovation of the Year, Lifetime Achievement and Best Media Work.

Patrick Kloss, Master’s graduate at the Helmholtz-Zentrum Hereon, won the award in the “Student Work of the Year” category for his master thesis entitled “Development of a digital model of a stationary hydrogen storage tank based on room temperature (TiFe) hydride”, which was pursued in the broad frame of HyCARE project.

New HyCARE scientific paper published in the International Journal of Hydrogen Energy

HyCARE’s researchers Jussara Barale of the Univerity of Turin (Italy) published the results on the alloy TiFe0.85Mn0.05 and


Moving from basic research to the implementation of hydrogen storage system based on metal hydride, the industrial production of the active material is fundamental. The alloy TiFe0.85Mn0.05 was selected as H2-carrier for a storage plant of about 50 kg of H2. In this work, a batch of 5 kg of TiFe0.85Mn0.05 alloy was synthesized at industrial level and characterized to determine the structure and phase abundance. The H2 sorption properties were investigated, performing studies on long-term cycling study and resistance to poisoning. The alloy absorbs and desorbs hydrogen between 25 bar and 1 bar at 55 °C, storing 1.0H2 wt.%, displaying fast kinetic, good resistance to gas impurities, and storage stability over 250 cycles. The industrial production promotes the formation of a passive layer and a high amount of secondary phases, observing differences in the H2 sorption behaviour compared to samples prepared at laboratory scale. This work highlights how hydrogen sorption properties of metal hydrides are strictly related to the synthesis method.
