Abstract :
The Institute of Gas Technology (IGT) has been developing gasification technologies since
the 1960 s for the purpose of producing synthetic natural gas, low and medium synthesis gas for power
generation and chemical production. AU types of fossil fuels were investigated from coal to oil shale to
biomass and waste. By 1994, the first commercial gasification plant based on IGTʹs U-GAS gasification
technology was completed. For biomass gasification, IGT developed the RENUGAS process. A 100
ton-per-day facility was designed and built in Hawaii to process bagasse. For the next step, IGTʹs biomass
gasification technology will be demonstrated at a 1000 ton-per-day alfalfa stem plant in Minnesota
to produce 75 MWe of power. This paper presents an update on the progress made in the Hawaii
plant.
