VIASPACE Inc. engages in the renewable energy business in the United States and internationally. It develops Giant King Grass (GKG), a biomass and energy crop. The company's GKG could be burned in biomass power plants to generate electricity; made into pellets that could be burned together with coal to reduce carbon emissions from existing power plants; generated bio methane through anaerobic digestion; and used as a feedstock for low carbon liquid biofuels for transportation, biochemical, and bio plastics, as well as animal feed.
