Abstract: With concerns on the increasing greenhouse gas emissions, CO₂ capture is the extensive interests in the world. One possible approach to mitigate this issue is to capture CO₂ from flue gas from combustion power plants to reuse it such as injecting CO₂ into the environment of greenhouse nurseries to enhance plant yield. Biogas burning power plants and biomass gasification power plants are promising technologies for energy production from biomass. In both technologies, the applicability of coupled carbon capture and utilisation technology to the plant was considered and the captured CO₂ was utilised in a greenhouse to increase its production rate. This work studies the simultaneous production of electricity and heat performance with the specific input of 10 tons of MSW per day as fuel. The results showed that the electrical power production rate of syngas-based CHP system biogas-based CHP system are 85 kW and 106.3 kW.

Keywords: biomass; combined heat and power; CHP; CO₂ capture and utilisation; energy and exergy investigation.
