Abstract
Produced CO2 from fossil fuel-based transportation vehicles and energy systems can have a direct impact on people who live in adjacent of the power plants. So, in the present work, we proposed and modeled an integrated system comprising a gas engine, a carbon dioxide capturing unit, an absorption chiller, and a greenhouse. The greenhouse uses directly the CO2 produced in gas engine through the carbon dioxide capturing unit to mitigate the emitted CO2 into the atmosphere. Besides that, the produced heating in gas engine could be exerted in a cycle to render the greenhouse space in cold weather condition. In warm seasons this thermal energy could also be delivered to an absorption chiller for producing required cooling for inside space of the greenhouse. Herein, the generated electricity is sold to grid, and an economic analysis is brought about. To evaluate and estimate the system performance and interest of selling electricity, a mathematical function was applied. The results show that, during cold seasons, the maximum possible net interest is 800,000 $, and for warm seasons is 2,500,000 $. The maximum COP is also achieved by 1.007. Finally, the amount of CO2 emission rate is mitigated at least 50%.
