Title: Graphene nanocomposite for the reversible hydrogen storage use

Project no.: GRAF-TECH/NCBR/07/24/2013

Duration: January 1^st, 2013 – December 31^st, 2015

Consortium:

1.      Lodz University of Technology, Łódź, Poland

2.      SECO/WARWICK S.A., Świebodzin, Poland

Objectives and methods:

The main aim of the project is to work out the technology for producing the functional nanocomposite material „GraphRoll” on the basis of polycrystalline graphene for reversible storage of hydrogen. The area for a potential application of the new nanomaterial in the nearest time horizon will be industrial technological facilities for heat and thermo-chemical treatment where hydrogen is a process medium or is used in high pressure gas quenching. Pumpless compressors based on „GraphRoll” will be provided for hydrogen recycling in the processes of  High Pressure Gas Quenching (HPGQ) as well as for hydrogen separation from exhaust mixtures of gases during operations of thermochemical treatment (low pressure carburizing - FineCarb and PreNitLPC).

Moreover, upon further improvement of the technology, it is expected that these new materials, when reaching the critical threshold of 6.5% wt. hydrogen absorption on an industrial scale, will be used for the storage of hydrogen in the vehicles of the future.

The nanostructure of that nanocomposite is based on the original method of polycrystalline graphene synthesis from the liquid phase. In the next stages the graphene is decorated by PVD spark and/or laser sputtering, then separated from the surface and finally rolled helically around the core fiber to reach 3D helical nanostructure with strongly developed area of active graphene with oligomeric pillars in between (Figure 1).
