Danish Vision 2050
The Danish
Vision2050 is similar to the vision for EU; but developed
to fit the targets and vsions of the Danish INFORSE members. The proposed
development follows in general the same path as in the European vision,
but given the large wind and possibly wave energy ressources in Denmark,
as well as an ambitious construction sector that have stated that it
can half the heat consumption of Danish buildings, the target is for
a phase-out of fossil fuels by 2030.
In 2030, where a large part of electricity is expected to come from
intermittent sources (wind and wave energy), there is a need for electricity
storages n addition to the extensive use of heat-pumps in cogeneration
systems and use of electricity for hydrogene productions in high-wind
periods.

A Sustainable Energy Vision for Denmark
By Gunnar Boye Olesen, the Danish Organisation for Sustainable
Energy (OVE), and INFORSE-Europe
OVE
and a number of other Danish NGOs have a vision to make a transition
of the Danish energy system to
rely on sustainable energy 25 years from
now.
In many respects, Denmark is well on its way with the transition
with an increase of windpower from 1% of electricity production in
1988 to almost 20% in 2005, a doubling of total renewable energy
use since
1991, no nuclear power, and large increases in efficiency. In spite
of the successes there is still a long way to go. We need clear political
decisions to guide the development, and we need to give up some “holy
cows”, such as the preference of gas over renewable energy,
the untouchable car etc.
There are a number of good reasons while Denmark should embark on a fast
transition to 100% renewable energy: Denmark is one of the richest countries
in the world and one of the largest CO2 emitters per capita. In addition
Danish oil and gas resources will be virtually exhausted by 2030. Denmark
has benefited from the first step of the transition with the development
of large windpower and biomass industries. Add to all this the global
dimensitons: the climate seems more fragile than previous estimated and
global oil supply is rapidly diminishing.
OVE’s vision is based on studies of the possibilities for renewable
energy and energy conservation, and a simple model that has been developed
based on the work of the International Network for Sustainable Energy,
which developed a vision for a European transition to sustainable energy.
The vision is a working model that is gradually improved as new information
becomes available.
Renewable Energies in the Vision
An important part of the vision is rapid increase
of renewable energy.This
includes a continued development of:
Windpower:
The level in 2030 could be 8500 MW of installed capacity, up from
3000 MW today. This
increase follows a study by the Danish power company Elkraft about
the possibilities for windpower developments. It could be realised
by replacing existing smaller windmills with new, large ones and
expanding
the off-shore development from close 500 MW today to 3500 MW. In
this way almost 2/3 of the power production will come from wind.
Solar Energy: The solar energy use could be 8 m2 per capita for solar collection,
5 m2 solar PV electricity and 3 m2 of solar heating. Even though
PV is
expensive, the PV development will cost less than 3,000 Eur per capita
with today’s prices. When this investment is shared over 25 years
in a period with falling PV prices, it will not be a burden for Denmark.
The solar heating will partly be for district heating.
Biomass: Biomass from existing production (wood, straw etc.) will continue at
present
level while biogas should be substantially expanded, maybe reaching
7.5 times the present level. Also energy crops should be expanded, and
could cover 14% of agricultural land.
In addition geothermal energy use should be expanded as have been done
in Copenhagen, and wave-power should be used to supplement windpower.
If the technical problems of wavepower are not solved, windpower should
be developed 20% more.

Strong
Emphasis on Efficiency
For electricity consumption, industrial production and transport is expected
that the end-use efficiency can be increased a factor-4 compared with
today’s level. It is well documented that thius is possible with
use of best available technologies. The increase of efficiency is a
slow process, and until 2030 is “only” expected a doubling
of the efficiency level compared with today.
Regarding transport OVE is in favor of a transport vision with a 40%
reduction of personnel car use and 55% reduction of truck transport.
This will partly be replaced by a factor-3 increase in rail transport
of 40% increase in bus transport. This will require a shift of existing
trends and doing away with the perception that longer distances of commuting
and increasing goods transport are positive developments. If the vision
is realised, it will remove most traffic jam, reduce noise and pollution
in cities and in several other ways contribute to better lives.
Regulating Intermittent Supply
Large parts of the energy supply will come from intermittent sources.
Solar heating is expected to cover 15% of district heating, which will
require expansion of heat storages with “monthly storages” for
solar heating. These heat storages can also be used for storing heat
from cogeneration of heat and electricity, de-linking the electricity
production from the heat consumption. In the power system the requirements
are larger as in 2030 up to 80% of the power production should come
from windpower, wavepower, and solar. Almost half of the intermittent
production could be used for flexible electricity use such as heat
pumps and hydrogen production, while the other half should be used
for normal consumption. This will require electricity exchange with
Norway and Sweden as Denmark does today, or electricity storages, such
as chemical storages.
The vision does not end in 2030. The efficiency can continue to increase,
which can free biomass that can be used in the chemical industry, where
it can replace fossil fuels as feed-stock for production of plastics,
lubricants, etc.

electricity
for export that is not
needed in Denmark because of increasing electricity efficiency.
