Cogeneration systems using a Stirling engine [2] are currently being developed and promoted by the European Union [1]. On the other hand, the EU climatic package obligates Polish energy producers to buy 100% CO2 emission rights from 2020 onwards. At that time, according to the experts a ton of CO2 could reach the price of 63.5 Euro. Attention is drawn to the fact that it is only then that nuclear power plants will become profitable, in the same way as wind power plants. This could result in substantial growth of energy prices, both for the economy and for households [3]. The paper presents the experimental research of a cogeneration system with a one-way Alpha type Stirling engine. The impact of the upper heat source and the type of working gas (helium and nitrogen) on the load capacity of the cogeneration system was studied. Based on a Sankey diagram, the power spread of the cogeneration system was analysed. On the basis of experimental research, a model was created of a cogeneration system consisting of the following submodels: Stirling engine of the second order, belt transmission, electric motor and an electrochemical battery. The Stirling engine was installed in a testbed, in the mechatronic lab at the Faculty of Automotive and Construction Machinery Engineering (SIMR) of Warsaw University of Technology. Furthermore, the impact of regenerator efficiency on the efficiency of the Stirling Engine was examined, which in turns impacts the efficiency of the entire cogeneration system.
