Waste is a valuable resource<br />
It is well known that household waste can be burned and<br />
thus generate energy. <strong>DONG</strong> <strong>Energy</strong> and its partners have<br />
developed brand-new technology that converts waste into<br />
energy more cost-effectively, more flexibly and more efficiently<br />
than combustion.<br />
<strong>DONG</strong> <strong>Energy</strong> has called this technology REnescience.<br />
Household waste directly from refuse trucks is treated<br />
with enzymes and becomes a liquid for energy purposes<br />
that can be converted into biogas and a solid fraction that<br />
can be used directly to generate electricity and heat.<br />
offshore wind farm, it is essential to keep to schedules so<br />
that the capital invested can start to be repaid as soon as<br />
possible.<br />
wind power challenges power stations<br />
In 2015, half of <strong>DONG</strong> <strong>Energy</strong>’s electricity generation capacity<br />
will be CO -free or CO -neutral, as electricity from<br />
2 2<br />
wind and hydro is expected to account for 36% of total capacity,<br />
while biomass will account for 17%. Gas will account<br />
for 30%, while electricity generation capacity from<br />
coal and oil will have been reduced to 17%.<br />
<strong>DONG</strong> <strong>Energy</strong> works concertedly to select and develop<br />
new offshore wind turbine projects. It is essential to have a<br />
large pipeline to enable us to meet our objective of continuously<br />
increasing the proportion of electricity generation<br />
from renewable energy sources. On top of its 1,025 MW of<br />
wind capacity at the end of <strong>2011</strong>, <strong>DONG</strong> <strong>Energy</strong> has made<br />
Metal and glass are also separated in the process for recycling,<br />
as well as nutrients that can be used for fertiliser<br />
in agriculture.<br />
“At <strong>DONG</strong> <strong>Energy</strong>, we see waste as a valuable resource<br />
and, with REnescience, we make much more intelligent<br />
use of waste than with other methods. We have developed<br />
the process from the laboratory to the demonstration<br />
stage. Now we will make REnescience part of our business,”<br />
says Manager Nanna Dreyer Nørholm, New Bio<br />
Solutions.<br />
final investment decisions regarding the construction of<br />
around 1,500 MW additional wind turbines, some of which<br />
are expected to be built together with partners thus reducing<br />
<strong>DONG</strong> <strong>Energy</strong>’s share (see figure on page 21).<br />
The fast-increasing volume of electricity from wind turbines<br />
in the Danish grid sets the Danish power stations<br />
completely new challenges. The power stations will play a<br />
different role in a future in which much more wind power is<br />
available as there will still be a need to balance electricity<br />
generation. <strong>DONG</strong> <strong>Energy</strong> is continuously striving to become<br />
more efficient at flexible, market-aligned operation<br />
of its power stations.<br />
