Nano technology for hydrogen storage

Nano technology for hydrogen storage

ID: F1510-05

One of the biggest hurdles for unveiling carbon-free vehicles that are driven by hydrogen stays finding a material capable of keeping enough hydrogen. Unfortunately, neither compressed hydrogen gasoline nor liquefied hydrogen is most likely to be capable of sufficient volumetric thickness. A new project created theoretical modelling, synthesis, characterisation and evaluation of novel nanocomposite materials for hydrogen storage space. It combined the newest developments in metal hydrides – compounds that bind hydrogen and launch it upon heating – with unique principles for tailoring material properties. Experimental work had been geared towards integrating metal hydride nanoparticles into nanocarbon templates that served as scaffolds to form nanocomposites. Cryo-infiltration had been one of the novel methods used for planning such composites. Researchers enhanced properties such as working temperature and stress, simplicity of reversibility of binding, and conversation between hydrides and the environment for improved security. Coating hydride nanoparticles into self-assembled polymer levels or encapsulating them in polymer shells provided stability and security against oxidation. NANOHY introduced advanced techniques such as inelastic or small-angle neutron scattering for investigating nano-confined systems. Experts demonstrated for the first time nanodispersion of complex hydrides into a microporous carbon scaffold. Magnesium hydride, amongst the best-studied metal hydrides, was shown to show modified thermodynamic properties when integrated into the porous carbon supports. Experts concluded that these thermodynamic effects are restricted to reversible hydrides and particles with sizes less than 2 nm. Finally, scientists successfully scaled up nano-confined hydrides and incorporated them into a laboratory test tank with promising results – a real breakthrough in the hard issue of hydrogen storage space for a hydrogen economy. The hydride nanoparticle demonstrated excellent cyclability, getting rid of the need for a catalyst. Twenty hydrogenation/dehydrogenation cycles had been performed. Except for hydrogen storage, other areas could benefit from this research, such as development of battery materials with greater storage capacities, better safety and improved cyclability. The task disseminated its findings in a number of magazines and at seminars and workshops.
