Pacific Gas and Electric (PG&E) sponsored a project to explore methods to gather powerline vegetation management woody biomass and process it into feedstocks optimized for delivery to distributed-scale gasifiers. A pilot study was conducted in Lake County, California where powerline trimmings were either chipped or baled, then ground at a central biomass processing facility, and finally milled / screened to achieve particle size distributions specified by a gasifier manufacturer. The vegetation included oak, pine, walnut, and other hardwoods. All materials were successfully processed into feedstocks.
