Conference: Advanced Solar Energy Systems based on Brayton Cycle Technology

Short- bio

Francesco Rovense obtained his Bachelor's Degree in Mechanical Engineering in 2011 and the Master's Degree in Energy Engineering in 2014 at the University of Calabria. In 2018, he defended his PhD thesis titled "Study of an unfired closed Joule-Brayton cycle in a concentrating solar tower plant with a mass flow rate control system". As post-doctoral fellowship at the University of Calabria, his research activity was focused on internal combustion engine cooling systems. Since May 2019, he works in the High Temperature Unit Process and his current research activity addresses new energy systems, based on poly generation Brayton cycle technology that makes use of concentrated solar technologies.


Brayton cycle technologies based on gas turbine engine are able to perform at high temperature and efficiency, changing quickly his operating condition in order to adapt itself to the required electric load variation. In addition, as gas turbine is an external combustion engine, it is possible to use different thermal power sources. In this way, also solar thermal technology is suitable to produce heat for this engine.

Gas turbine allows to produce electric energy with remarkable efficiency. Moreover, the possibility of using heat rejection allows to rise up conversion efficiency of the whole system. In CHP (combined heat and power) configuration, in fact, the heat energy is employed to heat city districts or industrial processes, while the combined power cycle converts thermal into electrical energy, using a bottom Rankine cycle.

Solar thermal technologies can be easily coupled with thermal energy storage, increasing power plant operational hours and releasing the energy stored when required by the power block.

Considering this scenario, control strategy of the power production and working fluid flow rates adjustment, play a key role in order to obtain a flexible power dispatching able to follow user demand.

Hence in this seminar, some Brayton cycle applications driven by concentrating solar power will be presented related to different scenarios, power plant layouts and dispatching strategies.
