Abstract
Distributed energy supply system is installed close to end-users with advantages of flexible consumption of renewable energy. Distributed energy supply system with integrating solar energy and clean fuel was conducted to achieve efficient utilization of solar energy and fuel. A distributed energy supply system based on the solar thermochemistry was proposed. The system integrated solar thermochemistry conversion and distributed energy system combined cooling
heating and power. The solar and methanol were complemented at the source in a thermochemical form
and the solar was converted into chemical energy of syngas
the cold
heat and power products were then exported through the
internal combustion engine electric generator and waste heat recovery units to meet the load demand of users. Through numerical calculation method
the thermodynamic performance and CO

emission performance of the integrated system were analyzed
and the performance under design and variable operating conditions was studied. The results show that the integrated solar energy and fuel thermochemical complementary energy supply system has significant advantages of energy saving and emission reduction.
