Article
Full-text available
The aim of the paper is to find the optimum design and performance of solar microturbines powered by parabolic dish collectors using an innovative methodology which integrates the design and off-design models of the total system. In contrast to the common practice of assigning an estimated efficiency to the engine turbomachinery (generalized perfor...
Article
Full-text available
The interest in Supercritical Carbon Dioxide (sCO2) power cycles has grown exponentially in the last decade, thanks to distinctive features like the possibility to achieve high thermal efficiencies at intermediate temperature, small footprint and adaptability to a wide variety of energy sources. In the present work, the potential of this technology...
Article
Full-text available
After the renewed interest in supercritical carbon dioxide cycles, a large number of cycle layouts have been proposed in literature. These works, which are essentially theoretical, consider different operating conditions and modeling assumptions, and thus, the results are not comparable. There are also works that aim to provide a fair comparison be...

Conference Paper
This paper provides an analysis of the Optimised Microturbine Solar Power generator (OMSoP) project, funded by the European Commission, as the most recent attempt to develop a dish and mGT Concentrated Solar Power generation system that is cost competitive against photovoltaics, at least in certain business cases. A first section presents the syste...
Article
Full-text available
Power cycles running on carbon dioxide at supercritical pressure and temperature were introduced in the late ninety-sixties but, after a warm welcome to the theoretical performance announced, they were later abandoned in favour of standard combustion gas turbines. Nevertheless, the technology was brought forward about a decade ago and has since cap...
Article
This paper presents a detailed cost analysis of a small-scale Concentrated Solar Power (CSP) generator based on parabolic dish collectors and Micro Gas Turbines (mGT), whose technical feasibility was already demonstrated in previous publications by the consortium. The system can be used for either electric power or combined heat and power generatio...
Conference Paper
Full-text available
The utilisation of supercritical bottoming cycles in gas turbine based power plants is not new at all. A number of works have already been published discussing the real potential of this configuration as compared to the standard technology using subcritical steam turbines. Nevertheless, the interest of this paper relies on the global approach to cy...
Article
This paper presents an innovative methodology to perform market analysis of a new solar power generation technology based on parabolic dish and micro gas turbine engines. Technical, economic, social and political parameters of influence are combined together into a single figure of merit: index of market potential. This index is an original approac...
