¿ä¾à2 In Korea, electricity is mostly generated by large-scale power plants such as coal, nuclear and LNG power plants. Small-scale power generation using renewable energy such as solar and wind power is also increasing recently. Biomass energy utilizing wood fuel (wood chips or wood pellets) is a typical renewable energy source along with solar, wind, and geothermal power. Power generation using bioenergy, especially woody biomass, can be accomplished by chemical conversion of woody biomass into bioethanol or other biofuels, combustion of wood fuel in a power plant to generate electricity using a steam turbine or organic refrigerant cycle (ORC), or gasification of wood fuel to drive an internal combustion engine. This paper characterizes small-scale cogeneration systems that can generate electricity and heat using wood chips. In particular, an organic refrigerant cycle cogeneration plant using wood chips and a wood chip gasification cogeneration plant were compared and analyzed in detail. Compared to gasification engine cogeneration plants, organic refrigerant cycle cogeneration plants have a high heat to power ratio (high heat output compared to electricity output) with an electricity efficiency of about 7% to 14%. In the case of wood chip gasification engine cogeneration plants, the electricity production efficiency is relatively high, ranging from about 10% to 36%.
