The fundamental purpose of this chapter is to examine a novel renewable energy supported combined plant. The suggested chapter occurs with biomass gasifier unit, gas turbine system, Rankine cycle, single-effect absorption cycle, hydrogen generation unit, dryer cycle, and hot-water production unit. This chapter is designed and developed for useful outputs, such as heating, cooling, electricity, hydrogen, drying and hot water with a single biomass energy input. In this context, detailed energy and exergy efficiency, and also environmental effect analyses are carried out with Engineering Equation Solver software. The effects of environment and gasification temperatures and biomass mass flow rate changes on the plant performance and on carbon emissions are investigated and presented as graphs. Results display that the energetic and exergetic efficiency of integrated plant are found as 63.84 and 59.26%. Also, the overall hydrogen generation and exergy destruction rate are 0.068 kg/s and 52,529 kW, respectively.
