Innovative services for cities: support to energy transition

Issue


Help Germany achieve its renewable energy and climate change objectives.
 

The customer's objectives

Support Braunschweig's Gliesmarode district in its transition to green electricity and heating.


 

Veolia's solution


Install a district heating network that runs on renewable energy. Launched by BS Energy, a Veolia Germany subsidiary, the Hungerkamp plant replaces 34 coal and oil-fired burners with a cogeneration plant, a wood-fired boiler and a natural gas-fired boiler, as well as two heat storage units.

 

Innovation

The Hungerkamp concept is a flexible cogeneration system that uses locally available renewable resources.

15 600 MWh/year

Heating provided to approximately 1 000 Gliesmarode district homes

60%  

 Share of heating from biogas produced from organic waste. The rest is broken down into 38 % wood and 2 % natural gas

8 000 tonnes

of CO2 emissions avoided every year

 

Technologies

Modern filtering system. The cogeneration plant is powered by urban organic waste (food waste, plants, etc.). The methane released by waste during decomposition is a biogas that is used as a fuel to produce green electricity.

Customer benefits


Environment

8 000 tonnes of CO2 emissions avoided each year due to conversion from fossil fuel and less harmful emissions.

The exhaust gases generated during combustion are purified and filtered before being released into the atmosphere.

Wood ash is converted into fertiliser.

 

Savings

The high reactivity of the heating network - a mix of biogas, wood, and natural gas as well as the heat storage unit - is a source of savings in case of fluctuating fuel prices or peaks in daily consumption.

 

Social/Societal

The plant uses wood waste from the region.
