Biomass and biofuel based poly-generation for off-grid and grid connected operation

Stirling Denmark (SD) has developed a unique Stirling engine technology which enables the conversion of low-cost biomass into high-value, CO2 neutral heat and power in small-scale (35-500 kWe) applications. The technology has a global potential as a combined heat and power technology for large buildings and small communities. Furthermore, the technology has the potential to substitute diesel generators as power generation technology in hundred of thousands of installations all over the world. The technology offers customer benefits in the form of cheap CO2-neutral electricity and heat, based on local fuel resources. Specifically the aim of the project is: 1) To make research in possible off-grid solutions. This will require new mechanical engine technology and new control strategies; 2) Develop and demonstrate a Stirling engine based plant which can operate under off-grid conditions and thus prove the potential for the technology as a substitute product for diesel generators; 3) To develop a modular system that enables simple and low-cost transport and erection of the plants (plug-and-play solutions); 4) To demonstrate the fuel flexibility of the technology with a range of solid and liquid biological fuel types; 5) To demonstrate alternative use of the heat generated in situations where heat is not needed.
