The Helmholtz-Zentrum Geesthacht GmbH (HZG), situated near the town of Geesthacht, Germany, belongs to the German Hermann von Helmholtz Association (HGF) . With its 18 research centres, 34.000 employees and an annual budget of approx 2.2 billion euros the Helmholtz Association is Germany's largest research institution.With its 15 research centres, 24.000 employees and an annual budget of approx 2.2 billion euros the Helmholtz Association is Germany's largest research institution. HZG is located at Geesthacht near Hamburg and has a branch in Teltow near Berlin with a total staff of approximately 800 employees, including about 420 scientists, engineers and technicians. The three main HZG research areas cover materials science, environmental research, and regenerative medicine. One of the core research topics at HZG are materials for hydrogen technology, covering production, purification and conditioning of hydrogen, and hydrogen storage. HZG has more than 14 years research experience in nanocrystalline light metal hydrides (more than 80 publications, 10 patents, 3 patent applications pending).

HZG was/is involved in international projects and co-operations in this field (EU IP’s STORHY and NESSHY, EU TN FC-TESTNET, Marie Curie RTN "H-Sorption in Mg"). HZG coordinated the Helmholtz Initiative " FUNCHY” (2005 - 2010), the MC RTN "COSY” (2006 - 2010) and the EU CP "FLYHY” (6 partners, 2009 – 2012).

In 2004, HZG (at the same time, but independently from the groups of Vajo, HRL, US, Y.W. Cho, KIST, Korea) invented the concept of Reactive Hydride Composites (European patent granted in 2011). In STORHY HZG constructed Europe’s largest tank for solid state hydrogen storage (8 kg NaAlH4). Its expertise was and is used in NESSHY and FLYHY for constructing improved versions. HZG is a member of the New European Research Grouping on Fuel Cells and Hydrogen, N.ERGHY.

HZG also has a strong background in materials design based on thermodynamics. For instance, the system Mg-Ni-H was calculated and modelled in detail using the THERMOCALC and CALPHAD (calculation of phase diagrams) methods. HZG operates own beamlines (German Engineering Materials Science Center GEMS) at the German Electron Synchrotron (DESY) in Hamburg, as well as at the Research Reactor Munich II. They are equipped for diffraction and scattering experiments to investigate structures in the range of Ångstroms up to microns.

HZG, besides project co-ordination (WP6), will focus on RHC preparation and properties improvements (WP1,WP2), scale-up and cost effective synthesis (WP4), on thermodynamic, kinetic and structural characterization (WP1, WP2), bring in its expertise in tank design and construction (WP5) and will evaluate storage performance of the storage materials (WP5).
