35 kWe electric output ~ 280 MWh/year
140 kWth thermal output ~ 1,120 MWh/year

The heat in the form of hot water is supplied to the Copenhagen district heating system. The heat will also be used in connection with a desalination unit, converting approx. 10 m3/hour of salt water into fresh water.

In August 2008, a project group led by Stirling DK was awarded a 650,000 EUR grant to demonstrate the potential of the Stirling engine technology as a substitute technology for diesel gensets and other power generating technologies.

• To develop and demonstrate a Stirling engine based plant which can operate under off-grid conditions and thus prove the potential of the technology as a substitute product for diesel generators
• To develop a modular, pre-installed system that enables simple and low-cost transport and erection of the plants
• To demonstrate the fuel flexibility of the technology
• To demonstrate alternative use of the heat generated in situations where heat is not needed

1. Building of a demonstration plant in three (2) standard 20' ship containers based on an updraft gasifier and one (1) 35 kWe Stirling engine. The plant will operate at the facilities of I/S Amagerforbrænding in the centre of Copenhagen, Denmark
2. Development of the engine, plant, and control system for off-grid operation
3. Development of a modular and container-based ”plug-and-play” plant system.
4. Demonstration of the potential to use the heat from the system to generate cooling and to desalinate salt water by adding an absorption cooling unit and a desalination unit to the plant.
5. Testing of a range of biological fuel types with the purpose of determining their applicability as fuel for a Stirling CHP plant. For each of these fuel types, operational data and emission data will be measured and reported. 

• A biomass fuel storage and feeding system.
• A 200 kW updraft gasifier.
• An SD designed combustion chamber with an integrated air preheater and with an interface for SD’s 35 kWe SD3-E2 Stirling engine.
• A 35 kWe SD3-E2 Stirling engine
• Units such as an economizer for heating of water, and a desalination unit for converting salt water into cold water. Commercial standard units will be used in the project.
• Control system for fully automated operation in both grid-connected and off-grid state. SD has already developed such fully automated control systems for the grid-connected state.

 In connection with the plant, Stirling DK has also made an exhibition centre containing information about the technology, biomass, combined heat and power, etc. We welcome visitors at this plant. Please contact us if a visit is of interest.
