New HyCARE scientific paper published in the Journal of Alloys and Compounds

HyCARE’s researchers Giovanni Capurso and José M.Bellosta von Colbe of the Helmholtz-Zentrum Hereon (Germany) published their results on thermal activation methods for industrially produced titanium-iron-manganese powders (TiFeMn) for hydrogen storage.

The work proposes an effective thermal activation method with low technical effort for industrially produced titanium-iron-manganese powders (TiFeMn) for hydrogen storage. In this context, the influence of temperature and particle size of TiFeMn on the activation process is systematically studied. The results obtained from this investigation suggest that the activation of the TiFeMn material at temperatures as low as 50 °C is already possible, with a combination of “Dynamic” and “Static” routines, and that an increase to 90 °C strongly reduces the incubation time for activation, i.e. the incubation time of the sample with the two routines at 90 °C is about 0.84 h, while ∼ 277 h is required for the sample treated at 50 °C in both “Dynamic” and “Static” sequences. Selecting TiFeMn particles of larger size also leads to significant improvements in the activation performance of the investigated material. The proposed activation routine makes it possible to overcome the oxide layer existing on the compound surface, which acts as a diffusion barrier for the hydrogen atoms. This activation method induces further cracks and defects in the powder granules, generating new surfaces for hydrogen absorption with greater frequency, and thus leading to faster sorption kinetics in the subsequent absorption-desorption cycles.

International workshop on Hydrides and Energy Storage in tribute to Michel Latroche

Michel Latroche, internationally recognized as a pillar of the hydride community, and more generally of research on the fundamental properties of materials for energy applications, passed away suddenly on December 30, 2021. Michel Latroche was the WP2 leader of the HyCARE project. His work was very important to guide the characterization of powder and pellets produced for the HyCARE system. The international day, which aims to outline the broad panorama of his research interests, is dedicated to his memory. It took place on Monday, June 13 at the ICMPE auditorium in Thiais.

Michel Latroche’s research activities have been mainly devoted to the study of alloys, intermetallic compounds, rare earths and porous materials having the property of reacting with hydrogen to form various compounds with remarkable structural, thermodynamic, physical and electrochemical properties. These hydrogenated materials are attracting ever-increasing interest, both fundamentally and applied. Indeed, they are able to store hydrogen and its isotopes under tuneable pressure and temperature conditions. They are currently used as electrode materials in commercial Ni-MH batteries and are being considered as electrode and electrolyte materials for future generations of Li-ion batteries

During the workshop, HyCARE’s coordinator Marcello Baricco presented the project, highlighting the key contribution of Latroche in the project.

HyCARE participated to the 2nd Reunion Plenieres de la Fédération (FRH2) du CNRS

HyCARE project coordinator Marcello Baricco participated to the 2nd FRH2 meeting organized by CNRS in Aussois (France). The meeting gathered more than 150 participants with more than a hundred oral presentations by young doctoral students, internationally recognized researchers and industrialists. This unique national event made it possible to take stock of current and future research on hydrogen storage devices, on all types of fuel cells, electrolysers, as well as on associated systems.

Baricco presented the “hydrogen cycle” and stressed the key role of storage to support the uptake of renewable energy sources. The HyCARE storage system was presented as an innovative technology for green hydrogen storage, allowing seasonal storage to support the wider use of renewables.

Jussara Barale defended her PhD thesis on hydrogen storage based on HyCARE’s R&D

Congratulations to the first HyCARE’s PhD awarded by the chemistry Department of the University of Turin to Dr. Jussara Barale. Under the supervision of Prf. Marcello Baricco, Dr. Barale performed research on hydrogen storage and compression systems based on metal hydride. The work of Dr. Barale was fundamental to understand the properties of metal hydrides in combination to phase changing materials for hydrogen storage.

Dematteis presented her latest work on HyCARE at HydEM 2022

HydEM2022

HyCARE’s researcher Erika Michela Dematteis presented at HydEM 2022 International Symposium her last work on “Mn-substituted TiFe alloys for large scale hydrogen storage application: an in-situ neutron diffraction study”. The presented results anticipates a publication that will be released soon on the neutron diffraction studies performed at neutron large scale facilities ILL and ISIS, to define the structural evolution of phases during the hydrogenation of the selected material for the HYCARE hydrogen storage system.

Hydrides as Energy Materials – HydEM 2022 is a point of reference for scientists of energy materials science, and the focus is on new hydrogen-containing materials for fuel cells, batteries, hydrogen storage, and conversion of CO2 into fuel.

HyCARE PhD student Jussara Barale presented her work at EHEC2022 in Madrid

EHFC2022

Jussara Barale, PhD student at the University of Turin, presented her research work on the HyCARE prototype during the 2022 edition of the European Hydrogen Energy Conference (EHEC2022) in Madrid. Barale’s presentation titled “Hydrogen – heat storage system based on metal hydride and phase change material”.

She showed the optimal working conditions for Phase Changing Materials (PCM) to properly manage Metal Hydrides (MH) in hydrogen absorption and desorption. The results from her experimental work provide insights on the best heat management strategy for promoting PCM contribution on H2 flow and TVP flow in hydrogen storage systems based on MH.

HyCARE at the World Hydrogen Leader event in Barcelona

Last 9th-10th of May, Jose Bellosta von Colbe from Helmholtz-Zentrum Hereon presented HyCARE in the World Hydrogen Decarbonising the Gas Grids Conference, organised in the framework of the World Hydrogen Leaders events.

A good opportunity to show the HyCARE project and its final results: industries and professionals have been updated with the innovation of the HyCARE storage systems and its prototype already built and tested.

A big thanks to the moderator, Manuel Coxe, Secretary General, MARCOGAZ and to the other panelists who shared their case studies: David Watson, from Cadent Gas Limited, Lisa Ruf, from Element Energy and Patrick Milin, from ENGIE.

HyCARE’s researcher F.Cuevas hold a webinar in the Master “Energías y Combustibles para el Futuro” of the Autonoma University of Madrid (Spain) on the research activities performed in the framework of HyCARE. Twelve students were actively engaged in the presentation. The webinar presented the activities and results including alloy design, tuning to thermodynamic operational conditions, activation and kinetic issues, as well as cycling stability, resistance to impurities and limited use of raw critical materials.

(S)TEAM today, make changes for tomorrow

HyCARE’s researchers E. M. Dematteis and J. Barale organized the Smart Labs as part of the event “(S)TEAM today, make changes for tomorrow”. Our researchers presented the HyCARE project and explained to young students why we should care about a renewable hydrogen future. They demonstrated how to produce hydrogen from small PV panels and to use the hydrogen produced as fuel for electric vehicles. Our young audience appeared very interested in hydrogen technology. Let’s hope to have inspired the next generation of hydrogen visionaries!

Green hydrogen: a valuable asset for the ecological transition

The Turin magazine “Nuovo Consumo” reports the interviews to our coordination Marcello Baricco on the advantages of green hydrogen. Baricco defines green hydrogen as an energy vector that can support the decarbonization of industrial processes and mobility, and the distribution of renewable energy with no GHG emission.

Baricco presents the current drivers and barriers for the uptake of green hydrogen in Europe and presents the HyCARE system as a valuable technology for medium-size hydrogen storage.
