10 Hydrogen Future: Toward Industrial Applications

should be investigated for hydrogen generation from harmful or less useful
hydrocarbons.
3. Several investigators have researched the generation of hydrogen from hydrogen
sulfide, assisted with transition metal-based nanomaterials. The nanomaterials
based on Cd [14], Zn [15], and Ti [16] are proven to be very useful in decomposition of hydrogen sulfide for liberation of hydrogen. The authors proposed that
the capturing of H 2 S should also be studied with nanomaterials along with the
decomposition. The H 2 S capturing is the major obstacle in the path of hydrogen
generation from the substance.
4. Storage of hydrogen via physisorption and chemisorption is considerably
improved with the utilization of nanotechnology. Different nanomaterials like
fullerenes [17], graphene [18], and nanotubes have played an important role in
this regard [19].
5. Nanotechnology is currently being used for the optimization of materials and
methods, employed in fuel cell development for superior functioning, stability,
and storage of hydrogen [20].
6. The enhancement in catalytic activity of a substance at nanoscale is an established
fact owing to the small size and enhanced surface area of the nanoparticles. In
a comparative study, the researchers at Technical University of Munich have
utilized nanoparticles of Pt and have achieved double catalytic performance in
comparison to the currently available materials in fuel cell applications. The
researchers have found that the cluster of only 40 Pt atoms is sufficient for
producing equivalent results as exhibited by mass of material, hence leading
to considerable cost reductions (as Pt is very expensive) [21]. The researchers
suggested the use of economical cobalt–graphene catalyst as the replacement of
expensive Pt materials in fuel cells [22].
7. There is radical improvement in the performance of the fuel cells by using the
nanomembranes. Several studies have claimed that nanomembranes are better
option as compared to the conventional membranes for fuel cell applications
[23].
In short, the nanotechnology is actively providing useful services in the commercialization of hydrogen. In this work, the authors tried to represent the current picture
of nanotechnology in generation and storage of hydrogen. The aim of the work is to
aid the researchers and scientists to explore new dimensions in the field of sustainable energy based on nanotechnology. In this way, the researchers can follow the
path of nanotechnology to overcome shortcomings and problems, hindering the way
to clean and sustainable hydrogen.
