The project aims to improve energy efficiency in the field of energy conversion by small devices, with particular reference to technologies for the conversion of electrical energy into other forms of energy, i.e. the conversion of thermal, solar or environmental energy into electrical or cooling energy, with a strong innovative value.

The activities carried out by RSE have clear technological characteristics, but the project does not overlook a systems approach. In fact, the issue of energy conversion through efficient technologies is, according to the EU, a highly relevant issue within the complex framework of energy efficiency. Any assessment in this regard, whether in terms of energy, economics, technology or plant engineering, must therefore be integrated into a systems framework.

This document summarizes the results of the research activities on the development of efficient small-scale energy conversion systems carried out by RSE during the PAR 2017 reporting period. Research areas were identified to assess application prospects and market penetration capacity, taking into account technical and economic viability, particularly where technology supply is most lacking. Research on mini/micro co-/tri-generation systems and polygenerative hybrid systems comprising heat pumps, thermophotovoltaics (TPV) and gas microturbines was addressed. An in-depth study of the production of electricity by bacteria through the breakdown of organic matter is also proposed. In this way, the project aims to provide input to broaden the range of technologies available to the end user, enabling them to make a more informed and committed choice.
