Abstract: The objective of this study was to propose a fusion-biomass hybrid system with fuel cell and gas turbine as a technical option for fusion application to generate electricity. Fusion reactor with dual coolants lithium lead (DCLL) blanket design employing SiCf/SiC could provide over 900 °C of high temperature heat for waste biomass gasification process. Waste biomass such as municipal waste solid and residues from agricultural and forestry sites could be sufficiently processed. A small scale conceptual fusion reactor GNOME is designed under the assumption that the system will be deployed in a place where a low amount of waste biomass is generated. Results showed that 364 MW GNOME reactor could produce 410 MWth power through divertor and blanket according to fusion power plant system analysis code (FUSAC). The hybrid system enables to generate 454 MWe with 80% capacity factor which is 7008 h operation in a year. Net electricity of 289 MWe could be produced through solid oxide fuel cell (SOFC) and gas turbine showed 30% of overall system efficiency due to the high self-consumption of GNOME reactor. The levelized cost of electricity (LCOE) is 208 $/MWh and the energy return on investment (EROI) is 3.9.
