The industrial and energy sectors are experiencing an important transition
phase from fossil and renewable resources, with the aim to shift from
a linear to a circular economy of production processes.
In this context, hydrogen is universally considered as one of the most
interesting energy carriers.
It can be produced sustainably from water and used either as a direct
energy source, or in mixture with other fuels, or as an important raw
material in the chemical industry.
Despite the great potential of
hydrogen, it still presents numerous application problems that must
be resolved before its large-scale use. Hydrogen produced from renewable
materials is not yet cost competitive compared to its production from
natural gas. Furthermore, it is necessary to evaluate application aspects
related to safety, the compatibility of materials, its distribution
and the optimization of traditional or innovative unit operations that
involve its use such as fuel cells, electrocompressors, transportation,
power to gas systems and others.
This Special Issue of Chemical Engineering Transactions covers the current
progress and innovations on all the hydrogen-based technologies for
its production, storage and uses.
Articles with innovative researches
and reviews with the critical analysis of the up-dated state of the
art will be welcome. All the different topics in which sustainable hydrogen
is a part of the process will be considered in the Special Issue, as
hydrogen generation, storage, infrastructures, transportation, synthetic
fuels, upgrading of oil and biomass, electrolysis, fuel cells, electrocompressors.
X-to-hydrogen-to-X, hydrogen carrier, CCUS, liquefaction and compression.
