Definition :
Hydrogen as an energy carrier
is considered as one of the solutions to the current energy challenge and
represents one of the most promising ways for sustainable energy utilisation.
However, renewable, CO2 neutral hydrogen production is very expencive, and most
of the hydrogen produced and consumed today is still derived from fossile
sources. The technology enables sustainable and efficient production of
hydrogen from different biological feedstocks. The Norwegian University of
Science and Technology (NTNU) is seeking partners to licence and participate in
further development of this novel technology for hydrogen production from
biomass.
Hydrogen production from
biomass is the only direct way to produce hydrogen from renewable energy
without a major technology breakthrough. Glycerol is one example of biomass
which can be utilised for producing hydrogen. The process opens opportunities
to combine biofuel and hydrogen production by using crude glycerol, a
by-product, from biodiesel production as feedstock for hydrogen production.
The technology is a one-step
method for production of pure hydrogen from biomass by sorption enhanced steam
reforming. This technology is wholly owned by NTNU and comprises (i) novel
catalysts (ii) novel sorbents, and also (iii) a system for regeneration of the
sorption material and catalyst which in all enables continuous production of
CO2-neutral and sustainable hydrogen of very high purity (99 % H2 dry basis).
ADVANTAGES
• Sustainable, CO2 neutral
hydrogen production
• Production of relatively pure hydrogen (99 % dry basis)
• Higher hydrogen yields in one single step
• Continuous production
• No need for shift reactors or CO2 absorption column
• Only traces of CO
• Lower working temperatures
• Autothermal process
• Production of relatively pure hydrogen (99 % dry basis)
• Higher hydrogen yields in one single step
• Continuous production

• Only traces of CO
• Lower working temperatures
• Autothermal process
The concepts have successfully
been tested in a continous lab scale model on several different biological
feedstocks. Nearly 100 % yield of hydrogen with purity over 99 % has been
achieved in a single step. Studies on better tolerance using raw bioliquids is
the current focus of the research. The process is also highly suitable for
other feedstocks besides bioliquids, such as natural gas, multifuels and
hydrocarbons in general. The overall goal is to commercialise this technology
by involving industrial partners.
