Abstract:
The struggle to decarbonise future power systems is boosting the diffusion of high-efficiency distributed multi-generation (DMG) systems. In this respect, small-scale (below 5 MWe) cogeneration systems for producing heat and power, as well as trigeneration systems for additional production of cooling, could play a key role. In this paper, a general analytical model for assessing the potential CO2 emission reduction from DMG systems, in case coupled to heat/cooling networks, is presented. Different available solutions are analysed. Numerical applications make reference to typical emission intensity figures in Europe. The results show that the emission reduction potential is primarily a function of the electrical efficiency and therefore of the size, and is strongly affected by the baseline comparative references. The environmental benefits decrease if part of cogenerated heat is used to generate cooling power with single-effect absorption chillers or adsorption chillers.
