Solid hydrogen storage

MAHYTEC offers a wide range of hydrogen solid storage solutions. The implemented technology relies on the use of hydrides, a metallic powder which absorbs and stores significant hydrogen quantity at low pressure and room temperature. Thanks to our complete control of the process of induction heating, we guaranty on-demand solutions as well as materials quality. Single unit or assembled, our storage solutions can satisfy all needs for most of the possible applications.

 Thanks to the control of the induction melting process, we secure a solution used to the needs as well as the quality of the material. Alone or assembled, our storage solutions can satisfy all your needs.

Application: Mobypost
Mobypost is an European project aimed at experiencing two fleets of vehicles with zero CO2 emissions on two mail delivery stations from La Poste
MAHYTEC contributes by providing its expertise and the supply of onboard solid storage solutions.
MAHYTEC is also involved in the design and the implementation of two refilling hydrogen station.
Financed up to 50% by Europe, this project was originally planned between 2011 and 2013 but has been extended till 2015.

Application: SBB Minibar
In 2013, the integrator CEKA on behalf of the Swiss company ELVETINO, which handles the trolleys of the Swiss railway company SBB, finds in MAHYTEC the reliable interlocutor to develop a H2 storage solution able to meet the challenge: increase the energy autonomy for a minibar available during the whole trip.
The H2 version of these minibars was implemented in April 2014 and has eliminated the autonomy and power issue of the original system with batteries.
