>8 Another planet, please !

We would love to contribute to
make Europe more sustainable.
We see that we could help to
save the world.

1980s Today
Carbon dioxide emissions have decreased with 25% - 50% in 25
years, while the use of district heating has grown rapidly. Emissions
of nitrogen oxides have fallen by around 80-90% and emissions of
sulphur are now almost negligible.

District heating is part of the solution for
minimising the use of natural resources.

Fuel mix in Gothenburg’s District Heating system.
Fossil energy 28%
Cogeneration (natural gas)
Boiler (natural gas, oil)
Recycled energy 28%

Some facts about district heating
• District heating grid length is over 1,000 km
• 7,000 (app 90%) connections to corporate customers and
• 12,000 (app. 20%) to private houses in Gothenburg + suburbs
Partille, Ale and Falbygden

District heating could soon be
everywhere.

New areas for district heating
that reduce dependence on
electricity.

Welcome to
CELSIUS
Headed by Gothenburg.
Contracts soon to be signed !!

CELSIUS
Why Celsius
‣ Europe, and the entire world, will face thorough change
in energy supply and energy policy.
‣ Celsius – Within the EU-programme Smart Cities – is
meant to contribute to reaching EU’s Energy Efficiency
target: 20 % to 2020.
Goals:
‣ CELSIUS is one corner stone for the EU, to demonstrate
and to promote roll-out of Smart District Heating and
Cooling through-out Europe, by presenting Best practice
to other European cities.
‣ The target is that 50 European cities should be dedicated
to the CELSIUS CITY- concept when project has ended.

(Euro Heat Cool)

How
CELSIUS
‣ IMPACT focus = Market, Acceptance, Behavior, Policy, Demonstrators, Financing and
Technology.
‣ The Project is headed by the City of Gothenburg and Gothenburg Energy.
‣ 21 welknown partners in the project (London School of Economics, Imperial College, Tech. University
in Delft….)
‣ Participating cities: London, Rotterdam, Genoa, Cologne, + 7 cities that already have shown interest.
‣ Financing: EU’s single largest Smart City project, supported by EIB.

What’s in it …:
CELSIUS
…For EU:
‣ Replicability of district heating / cooling concepts.
‣ 13 new demonstrators to be built within the project.
‣ 50 dedicated cities in 2016.
‣ Vision: Fully deployed 100TWh reduced energy consumption in
EU.
‣ Vision: 100 dedicated CELSIUS cities in 2026.
‣ One tool for reaching the energy efficiency targets.
…For Gothenburg:
‣ To coordinate an interesting project and to become the Smart
reference City in EU regarding District Heating and Cooling.
