Short description of research fields In a
longer term hydrogen is believed to become the foremost energy carrier. The
major components in the expected Hydrogen Economy involve
production, storage, transport, and final use of hydrogen, all of them with
considerable technological challenges. This implies a need for new
technological solutions where fundamental aspects related to the function of
materials, components and systems are in focus.
Research at the intersection between energy and environment is a
prioritized area in Norway. Of particular importance is to further enhance
activities already being at a high international level, involvement in
international networks and active partnership in joint projects with leading
industry, both Norwegian and international. FUNMAT has its focus on materials
that are of utmost importance in the hydrogen-chain; from production, via
storage and end use of hydrogen. Such research has long tradition in Norway
with established links industry. The gravity of activities lies within
materials chemistry, electrochemistry, solid state physics and theory.
The FUNMAT partners are involved in several projects funded by the
Research Council of Norway, EU, the Nordic Energy Research Program, and other
international funding sources.
With respect to excellence and critical mass, FUNMAT will point at
the following fields (web-links will be established to the mentioned
topics):
Hydrogen production from natural gas Environmental-friendly
and sustainable hydrogen production from natural gas is naturally in focus
owing to huge Norwegian gas resources. FUNMAT groups are e.g. involved in
catalyst development for improved synthesis gas production. Reactor types such
as fluidized bed reactor, membrane reactors, short contact type reactors and
more recently heat exchange reactors and microreactors are studied for small
scale production of hydrogen for fuel cell applications.
Membranes for hydrogen separation. Currently, there are
significant activities in the field of microporous ceramic membranes, dense
mixed conducting ceramic membranes and dense Pd-based metallic membranes.
FUNMAT is involved in several European and industry funded projects to develop
such membrane technology. FUNMAT partners are well equipped for preparation
(sputtering, sol-gel), characterisation and testing of membranes. Testing can
be done up to high temperatures and high pressures relevant in hydrocarbon
reforming and water gas shift reactions.
Hydrogen production by plasma cracking of hydrocarbons A new
plasma process developed by Kværner Oil and Gas and SINTEF Materials
Technology provides carbon black and hydrogen (CB and H2) from hydrocarbons
with no emissions. The new plant in Canada, Karbomont, is the first using
high-temperature plasma technology to produce CB and H2. Core technology is a
high temperature reactor in which the plasma torch (developed and patented by
SINTEF) provides energy to decompose hydrocarbons directly into carbon and
hydrogen. All types of gaseous and liquid hydrocarbons, from gas to heavy oils,
can be used.
Materials for hydrogen storage. The research and competence in
FUNMAT cover hydrogen storage in intermetallic metal hydrides, complex hydrides
(alanates etc), inorganic-organic hybrid materials and carbon-based materials
(incl. nanotubes and carbon nanofibers), as well as studies of the importance
of nanostructuring and catalysts for hydrogenation. The partners have strong
activities on syntheses of new materials (arc melting, induction melting, rapid
solidification, ball milling techniques and hydrogenation) and
characterization. All standard methods for surface and thermodynamically
characterization are available, including PCT
(Pressure-Composition-Temperature) and desorption spectroscopy. High-resolution
powder neutron diffraction at the Norwegian Kjeller reactor (PUS-instrument)
gives unique possibilities for structure determination of materials for
hydrogen storage and in-situ studies of adsorption/ desorption processes. In
addition, state-of-the art X-ray diffraction, excellent access to
high-resolution powder X-ray diffraction at the Swiss-Norwegian Beam Lines at
ESRF and state-of-the art TEM and SEM instruments for electron
diffraction/microscopy provides quality and strength within structural
characterization. Temperature, pressure, atmosphere (e.g. hydrogen) can be
varied in the diffraction experiments.
Hydride batteries With basis in competence in hydrogen
storage (see above) and electrochemistry, activities aim at developing improved
alloys for metal hydride batteries and hydride electrodes. Alloys are prepared
by rapid solidification, arc melting or induction melting techniques. There is
high competence in impedance characterization and modeling of hydriding/
dehydriding in porous electrode systems.
Materials for PEM technology The FUNMAT partners have
competence in both PEM technology for water electrolysis and fuel cells. For
hydrogen production the highly effective electrode catalysts based on Pt
(cathode) and mixed Ir/Ru-oxides for the anode are of particular interest. The
PEM Fuel Cell work is focused around fundamental electrochemical studies
(electro-catalysis, electrode optimization) and also surface treatments and new
membrane materials are being tested. Mathematical modeling based on
conventional electrochemical theory, irreversible thermodynamics and fluid
dynamics supports the experiments.
Materials for solid oxide fuel cells (SOFC) Proton
conducting oxide materials are intermediate temperature proton conductors with
potential applications in fuel cells. High expertise in defect chemistry and
studies of transport phenomena combines in FUNMAT with activities searching for
novel, improved materials. In addition FUNMAT has expertise in electrochemical
characterisation of electrode materials, determination of kinetics and
mechanisms of the electrode processes and measurements of oxygen transport
properties.
Theory and modelling is done on many levels, from quantum
physics and chemistry, via understanding of electronic phenomena to ionic
transport and macroscopic behaviour of materials. FUNMAT has strong activities
in modelling of solid materials using Density Functional Band Structure Methods
(DFT). This approach is used to understand the bonding in materials for
hydrogen storage and the absorption process of hydrogen through metal surfaces.
