Sustainable biomass-driven heating, Bio-hydrogen, and power production scheme with desalination unit

Abstract

In this study, a multi-generation energy system is modeled for the purpose of simultaneous producing distilled water as well as biofuels, electrical power, and thermal energy from wood chip biomass. The system is triggered by a gas turbine cycle with two different agents of steam and air. The system performance is evaluated by changing the gas turbine cycle working fluid and their performances are compared in details. The research findings indicate that the air-powered system demonstrated an efficiency of 67.38 %, surpassing the steam-powered system which exhibited a slightly lower efficiency rate of 67.17 %. The results indicated that the air-driven system displayed superior emission characteristics in comparison to the steam-driven system. The air-based system was found to release 510.3 g/kWh of carbon dioxide, whereas the steam-based system exhibited a marginally higher emission rate of 511.9 g/kWh. The study's results indicated that the air-powered system exhibited superior performance in comparison to the steam-powered system. The study illustrated that the integration of wood chip biomass into energy systems offers an environmentally sustainable and economically viable solution to address the increasing need for clean technologies.
