Description
Summary:•Demonstration of the feasibility of a solar-hybrid plant with gas turbine.•Solugas plant operation data and behaviour.•Pressurised tubular air receiver efficiency evaluation.•Great performance of heat exchange process achieving receiver outlet temp of 800°C. This article presents the first megawatt scale solar-hybrid plant with a solarized gas turbine. The works and improvements that made the Solugas project succeed during design, construction and long-term solar operation are described and explained. More than 1000 operation hours and receiver outlet temperatures of 800°C were achieved. The operation behaviour and performance of the key components – the solar pressurised air receiver and the gas turbine – are presented here as a proof of the high potential of the technology.
