Abstract

In this study, a performance assessment of a novel solar energy-based multigeneration system integrated with a thermochemical cycle is performed. A steam generator is also integrated to reach high temperatures which are required for the thermochemical cycle. While 550 °C is reached with solar tower, the temperature is increased to 750 °C, which is the maximum temperature of the cycle, with the steam generator. Hydrogen is produced by a calcium-iron bromide cycle and is blended with natural gas. The blend is supplied both to the boiler of the organic Rankine cycle and a community to utilize in combi boiler and gas cooker. The reverse osmosis and multi-effect distillation units are integrated to produce fresh water for the community which consists of one thousand houses. 9.3 MWh electricity is supplied by organic Rankine cycle with 41.27 million m3 hydrogen and natural gas blend. Furthermore, a total of 7.2 million m3 of the blend is utilized for household appliances including gas cookers and combi boilers.
