for
Why this study?
The heating and cooling sector has largely
been overlooked in all scenarios exploring the
energy future towards 2050.
This study focuses on the future European
heat and cooling market and its importance in
terms of cost-savings, job creation,
investments, and a smarter energy system
Existing Studies
Existing
reports:

Consensus:
”Combined heat & power (CHP) and
Fail

proper

district
heating (DH)
are important”
of heating and cooling
Have a too low time and geographical resolution to model
. . . but fail to quantify to which extent
the realitiesthese
of the
energy
market,
DHC
options
can be
used in especially
the
future energy system . . .
Acknowledge
the importance of DHC until 2030/2050, but
Assume high shares of electric heating, low heat
The European
Commission in theand
Energylow
Roadmap
2050 communication:

shares
of DHC by 2050
“An analysis of more ambitious energy efficiency measures and costoptimal policy is required. Energy efficiency has to follow its economic
potential. This includes questions on to what extent urban and spatial
planning can contribute to saving energy in the medium and long term;
how to find the cost-optimal policy choice between insulating buildings to
use less heating and cooling and systematically using the waste heat of
electricity generation in combined heat and power plants.”

 100 TWh Geothermal
 100 TWh large-scale solar
 65 TWh wind (due to a
smarter energy system)
Context: 2050 total
heat is 2600 TWh
Energy Efficiency
 Demand side is extremely
important, but eventually it
will become expensive
 Supply side also has many
options:
 PP converted to CHP
 100 TWh surplus industrial
heat
 200 TWh heat from waste
incineration
Case Study: Århus
Legend
District heating area
Built up areas
Aarhus municipality
Case Study
Conclusions
District heating is an attractive solution in areas
with a high heat density
District heating can be seen as an efficiency
measure similar to reductions in heat demand,
because it enables the use of fuels in a more
efficient way
Heat reductions in buildings can be combined
with district heating so that it is competitive with
individual solutions
HRE1 Conclusions
If we continue under a
business-as-usual scenario,
then district heating can:
Reduce the PES
Reduce the CO2 emissions
Reduce the costs of the
energy system
Use more renewable energy
HRE2 Conclusions
If we implement a lot of energy
efficiency measures, then district
heating will:
Meet the same goals:
Utilise the same amount of fossil fuels
Enable the same CO2 emission
reductions
BUT, Cost approximately 10% less

Is DHC beneficial for the EU energy
system in a ??? scenario?
Research To Be Continued…
Develop national plans that connect the
local (mapping) and EU (modelling)
results.
Optimise the EU energy system by
reducing baseload electricity and
developing more smart energy system
technologies

Benefits of District Heating
 Improves the efficiency of the system (CHP, O&M, etc.)
 Creates short-term and long-term flexibility
 Enables more renewable energy resources and surplus
heat to be utilised
 Reduces the thermal capacity necessary
 Increases the comfort-levels for the end-user
