Systems analyses, etc.
The energy sector traditionally makes use of socio-economic analyses including
energy systems analyses. There is a need, especially in the field of new energy
technologies, such as hydrogen and fuel cells, for knowledge of the economic,
political, social and environmental consequences as well as the safety aspects of
various development alternatives.
The analyses comprise: various sorts of
energy systems analyses (static or dynamic
modelling, input data generated through
projection or foresights or a combination of
the two), life cycle analyses (total costs and
environmental loads from hydrogen
production) as well as policy analyses and
evaluations of various aspects of the
There are many players with
competencies in systems analyses
and other socio-economic analyses,

Laboratory, Energinet.dk, Danish
Transport Research, AKF and
several consultancy firms.
development and marketing of new energy technologies including the importance
of standardisation, patenting and IPR. Analyses of potentially undesirable
climatic effects of hydrogen use on the upper layers of the atmosphere would also
be considered.
The use of hydrogen-driven vehicles presents many safety aspects that need to be
investigated before they can be introduced. It may be necessary to conduct
destructive tests (collisions) to gain experience with high-pressure hydrogen.
