Modular Biomass Power Systems to Facilitate Forest Fuel Reduction Treatment
Demonstrating a commercial scale gasification facility for converting forest wood waste to electricity.
The project yielded important results that did not support the initial hypothesis that the recipient's CircleDraft gasification system was appropriate for the California market. However, the project did result in the development of a more robust modular system (rotary gasifier integrated to an Organic Ranking cycle (ORC) generator) that addressed critical technical challenges experienced with the initial system including material flow issues associated with forest material, associated producer gas output and quality fluctuations, and high engine generator maintenance requirements. Based on testing done with match funds, the rotary gasifier + ORC generator configuration is ready for a commercial technology demonstration in a California forest sector community.
This project develops and tests a modular biomass gasification system that can be rapidly deployed to communities across California to promote and support fire-safe management activities.
The rotary gasifier and ORC generator configuration has a levelized cost of energy of $242/MWh, resulting in the more favorable business case and economic performance of the four systems evaluated in the project. If biochar is in
It is estimated that approximately 4.9 jobs are created per MW of bioenergy generation. Most bioenergy facilities are, and will be, sited in rural areas that are experiencing significant economic hardship.
Unlike traditional dir
This project will help with sustainable forest management by removing overgrowth and dead trees from the surrounding forested area, preserving forest carbon sequestration and protecting key watersheds.
Ratepayers can benefit from community-scale forest gasification technologies because of the ability to more proactively manage the forested landscape. Conventionally wildfire risks are mitigated by treatment of forest landscape a
