Small and micro energy sources are becoming increasingly important in the current environmental conditions. Especially, the production of electricity and heat in so-called cogeneration systems allows for significant primary energy savings thanks to their high generation efficiency (up to 90%). This article provides an overview of the currently used and developed technologies applied in small and micro cogeneration systems i.e., Stirling engines, gas and steam microturbines, various types of volumetric expanders (vane, lobe, screw, piston, Wankel, gerotor) and fuel cells. Their basic features, power ranges and examples of implemented installations based on these technologies are presented in this paper.

“…Another industrial application of FPSEs is in combined heat and power systems (CHPs) or cogenerations. Indeed, the CHPs can generate heat and power simultaneously with high efficiency, which have received considerable attention recently . In this field, the Sunpower, Remecha (Baxi), and Viessmann Companies are known as the precursor to develop CHP technologies .…”

This paper presents a detailed review on free piston Stirling engines (FPSEs) technology. Generally, the Stirling engines can be categorized into two broad classes comprising kinematic and dynamic converters among which FPSEs are known as the dynamic type. Other well-known dynamic Stirling converters are Fluidyne and thermosacoustic engines among which the thermosacoustic ones are the most advanced Stirling converters recently presented. In this research, the dynamic Stirling engines are first introduced and reviewed. Then, the review work is directed toward the FPSEs, one of the most reliable dynamic Stirling converters utilized in different applications such as combined heat and power systems (CHPs). Subsequently, the working principles of different types of FPSEs and their performance are summarized. Next, several manufactured FPSEs, as well as their corresponding features and applications, are discussed. Finally, the article is conducted to analysis and modeling approaches of FPSEs.Accordingly, linear and nonlinear analytical techniques of FPSEs are introduced, and some comparative data are provided to verify the modeling schemes. Then, various design parameters affecting the engine performance are introduced and studied. The outcomes of this review work demonstrate the potential of FPSEs for different applications and reveal that the perturbation-based model is likely the most comprehensive nonlinear method for modeling and design of the FPSEs.

“…Furthermore, free-piston Stirling engines are preferred to meet the electrical needs of spacecraft by converting the heat energy of nuclear fuel into electrical energy in the dark regions of space where electricity cannot be generated from solar energy. 15,16 Stirling engines run with high efficiency, high performance, low fuel consumption, and without noise or vibration compared to internal combustion engines. Most of the heat losses occurring in Stirling engines are lost by cooling water.…”

In this study, to develop a power generation system that can use renewable energy resources more efficiently, a beta-type Stirling engine with rhombic mechanism was designed and manufactured. Kinematic and thermodynamic analyses of a beta-type Stirling engine were performed numerically in the Fortran program.Volume and pressure changes depending on crankshaft angle of Stirling engine were made using the isothermal analysis. The effects of the basic parameters related to engine performance, such as working fluid mass, charge pressure, heater, and coolant temperatures, on the net work amount were investigated. Five different gases, including helium, air, nitrogen, carbon dioxide, and argon, were used as a working fluid in experimental studies. The effects of all these gases on engine performance characteristics were examined at charge pressures of 1 to 5 bar for two different displacer pistons made of stainless steel and titanium material. The performance characteristics of Stirling engine manufactured were tested using a specially designed electrical heater, at 727 C hot end and 27 C cold end temperature, depending on engine speed. In all experimental studies, maximum power output was acquired to be 215.48 W, at 4 bar and 550 rpm when a stainless steel displacer piston and helium gas as a working fluid were used, and maximum torque value was acquired to be 7.54 Nm, at 5 bar and 150 rpm. The lowest engine power output among maximum engine powers was acquired to be 34.66 W when argon gas was used as a working fluid at 3 bar and 300 rpm, using a displacer piston made of titanium material. Maximum power output acquired in the experimental studies using a stainless steel displacer piston and helium; it was determined that it is 72.12%, 73.69%, 241.49%, and 288.81% higher than the engine power acquired by nitrogen, air, carbon dioxide, and argon gases, respectively.
