## 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](/en/solutions/district-heating-cooling-networks "District heating and cooling networks") 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](/en/solutions/cogeneration-and-environmental-performance "Cogeneration and environmental performance"), 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](/en/solutions/biogas-renewable-energy-landfilled-waste "Biogas: renewable energy from landfilled waste") 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.
