Fixing two problems at once
Not all solutions
to the energy crisis
and the dependence on Russian natural
gas
will help the green transition
or
be relevant in the longer run.
Prioritize
the solutions that
solve many
problems
and
continue to deliver!
District heating (DH) -
a tool to counter the
European
energy crisis
District heating can deliver
simultaneously
on
•
Reduced import of Russian
natural gas
•
Increased security of supply
•
Green transition
•
Also: Energy efficiency, sector integration, jobs
and fuel poverty

All hands on deck!!
District heating (DH) -
a tool to counter the
European
energy crisis
Many tools are in play to reduce the reliance on
Russian natural gas
No single supply chain will be able to deliver independence
of Russian natural gas.
District heating is growing and already on the way to reduce
the reliance on Russian natural gas and increase the security
of supply in Europe.
DH is a cost-efficient
and sustainable “no-regret”-solution.
Tool for Europe:
Accelerate the growth of DH

District heating works!
Recognized in Europe as a critical tool for the green transition
Case:
Germany
Cities such as Berlin, Hamburg, Mannheim, and
Freiburg have been heated by DH for a long time.
Going from ambition to action, Germany is now
deploying extensive heat planning. DH has been
identified as a “key solution” with benefits such as
costs, efficiency, flexibility, diversity, local value
creation, and security of supply.
An estimated 700 German municipalities are facing a
new task of heat planning, if plans for mandatory heat
planning are carried out. To assist the municipalities,
a national competence centre for the heating
transition has been founded.
This is expected to result in massive investments in
green heating across Germany. With DH being one
of the favoured solutions.
District heating (DH) -
a tool to counter the
European
energy crisis
Case:
Polen
There is a lot of DH in Poland. More than 40% of
households are heated by DH, and the Warsaw DH
system is the largest in Europe.
Poland considers DH to be a strong asset and a most
important, integral part of their green transition.
Currently, DH is predominately based on coal and is
faced with the challenges of transformation. Poland
knows that large investments and efforts are needed.
An extensive strategy for green transition and
improved energy efficiency is on the way. This
includes also cogeneration using low-emission fuels.
Case:
Denmark
Denmark has responded to previous energy crisis by
developing district heating with the support of heat
planning.
The philosophy being
–
with heat infrastructure in place,
you can use whatever energy source is cheap and available.
For decades, this heat infrastructure (DH) has facilitated
quick and cost-efficient transitions. From oil to natural gas
to biomass, and now to a diverse mix including surplus
heat, electrification, and ambient heat sources.
The main reason behind the success of the green transition
in Denmark is district heating. DH is now expanding to help
eliminate the remaining use of natural gas for heating.
DH will be 100% CO
2
-neutral in 2030 in Denmark
People associates DH with cheap, green, and reliable heat,
and the current prices seems to support this: 90% of Danish
DH consumers have not experienced an increase in prices -
though gas and electricity prices have gone up
dramatically.
It is clear that individual heat pumps are not a
suitable solution on the needed scale. The electricity
grid is already facing major challenges. DH is needed
and offers a more attractive path on a large scale.

DH can reduce reliance on Russian
gas - both short and medium term
Accelerate what we have!
•
Prioritize non-gas heat production in existing DH systems on a
daily basis. Replacing or reducing the use of natural gas for
heating for the whole DH area.
Connect more buildings and industries inside and near
existing DH systems.
•
Convert heating from natural gas to DH.
•
Supply local companies with DH-based process heat,
possibly boosted by electric heat pumps.
Accelerate existing DH plans for green heat production.
District heating (DH) -
a tool to counter the
European
energy crisis
Accelerate what we need!
•
Expand, modernize and establish DH systems across Europe
through an accelerated planning and approval process.
Diversity in heat production, heat planning, and sector
integration will result in a cheap and resilient heat sector.
Address the misunderstanding that DH takes a very long time to
establish. DH is not technically difficult. Ensure that decisions are
made.
DH is a fuel-flexible heat infrastructure that can use all heat
sources. Don’t be too afraid of fossil heat sources (except
natural gas) if already available
–
their importance can decrease
over time. DH is the opposite of a lock-in technology.
Think big!
•
Plan city-wide
•
Include existing and future heat sources, also surplus heat
from carbon capture and hydrogen production.
•
Connect all end-users
•
•
•
•
•
•
Stop heating based on natural gas in new developments.
Optimize and digitalize existing DH systems to increase
energy efficiency and reduce energy demand.

Summary
Many big
decisions will be made
to reduce the
dependence on Russian gas.
Europe needs to act quickly
–
without forgetting
the long-term perspective.
District heating (DH) -
a tool to counter the
European
energy crisis
TOO FEW PEOPLE KNOW,
that district heating is a
critical tool for both the current crisis and for the
green transition.
