Hydrogen combined cooling heating and power system provides an efficient and holistic means of meeting multiscale and multidimensional energy demands through short, medium and long term storage. The energy generation consist of solar thermal heat, photovoltaic electricity and wind power. The energy storage consists of short term battery storage, medium term heat storage and long term hydrogen storage. The general focus is on the system level integration and simulation of the entire system and a particular focus on the parabolic trough receiver shape and the control at the low level, high level supervisory logic control that manages the entire system. Furthermore, the fabrication of an experimental rig is performed originally for the validation purposes of the thermal system, in which the heat transfer characteristics of different nanoliquids under different natural light conditions is assessed. The results show a good performance for control reference tracking and disturbance rejection of the solar radiation. Research on the shape optimisation of the receivers of the parabolic trough reveals that the triangular shape provides a superior performance compared to the classical semi-circular shape in absorbing solar radiation. Also, a system level control oriented model, supervisory energy management system and experimental measurement system to study hydrogen combined cooling power system has been developed. The computational and experimental models developed in this research programme provide a strong basis for further studies, including the analysis and operation of hybrid hydrogen combined cooling energy system in the real tracking space and its overall system control and optimisation.
