“…Brandoni et al [15] emphasize the ability of micro-CHP energy systems to increase energy security, achieve climate targets, and move towards sustainable development. Incili et al [16] mention the micro-CHP advantages to provide more energy security when they propose a fossilbased (coal), micro-CHP Stirling engine, and PV system. Elmer et al [74] consider energy security when analyzing the advantages of fuel cells and comparing them to traditional combustion-based systems, such as the Stirling engine.…”

Reliable heat and power supply are among the basic household needs nowadays. It is especially topical in rural or distant locations that may be cut off from the energy grid due to extreme weather or other events. Nonetheless, the sustainability of our power production systems has to be considered to sustain our planet’s long-term abilities to provide energy resources and a viable environment. Renewable energy resources must be prioritized in rural and remote areas, simultaneously strengthening distributed production ability and self-sufficiency. In this context, the use of the Stirling engine for heat to power generation in households, on the scale of small communities, and by using only renewable resources is becoming increasingly topical. Therefore, this research aims to identify the current state-of-the-art for Stirling engine applications using biomass as a renewable energy source, in the context of sustainability and energy security. The paper summarizes the current research tendencies at the household level in the use of biomass-based Stirling engines for renewable heat and power generation in decentralized energy systems. The methodology applied is a structured literature review and content analysis. The research results corroborate the progress towards the use of renewable resources and towards increased energy efficiency because the keyword and overlay analysis showed more frequent publishing in these areas. The content analysis on two more specific sub-directions of interest, i.e., biomass-fuelled Stirling engine use in households and Stirling engine implications on energy security, showed that though research activity in these directions has increased lately, more profound research is needed, especially on aspects of energy security and independence. The content analysis revealed a lack of in-depth analysis on the effects of Stirling engine use on energy security or energy independence, which is suggested as a topical subject for future research.

“…The results indicated that the system not only can meet all the energy consumption in a typical household but also produces surplus electricity, amounting to 31.8% of total generated electricity, to export to the electric grid. Incili et al [49] also proposed a photovoltaic and Stirling engine-assisted micro-CHP system. The system used a coal-fired boiler as the heat source to produce hot water and power a beta-type Stirling engine for electricity generation, while additional electricity was generated by a set of solar photovoltaic panels.…”

The present study experimentally investigates the performance of a power generator constituted by an unpressurized Stirling engine coupled with a new flat-flame burner. The operative temperature differential of the Stirling engine is within the medium range (around 400 K or less). In this work, there are two types of the engine’s hot-end-plate designs, a conventional flat plate and the new type with spiral fins developed within this framework. Consequently, the new hot-end-plate design forms spiral-patterned channels to enhance the engine’s heat input rate, thus partly compensating for the inherently low thermal efficiency of an unpressurized engine. The spiral fins are used to increase the resident time of the flue gas and increase the heat-transfer area. In addition, engine performance is measured for two types of fuels, namely, DME (renewable) and propane (fossil). Using propane, the new hot-end plate allows for a maximum electric power output of 24.6 W, which is typically superior to common unpressurized Stirling engines. Compared to the conventional hot-end plate, the new hot-end plate improved electric power output and the thermal-to-electric efficiency up to 63% and 47%, respectively. The study also proved the effectiveness of applying the integration of the new hot-end plate and the new flat-flame burner on boosting the power output of the present Stirling engine generator.
