Non Technical Summary
The Biomass Fuel Blocks (BFB) process transforms low value forest slash to dense logs that have high value as a renewable energy feedstock for power plants and biofuels plants located at some distance from the forest. The delivered cost can be lowered by 46.3% through BFB densification of forest residues. Given the economic advantage of this approach, the USDA Western Regional Research Center supports a CRADA that would further upgrade the BFB bioproduct for end use in the large and growing co-firing power plants.In this project, Altex will develop a portable BFB system that will produce dense logs inside the forest at a capacity of 2.5 tons/hour. To accomplish this objective, the densification equipment available at Altex will be modified to operate only on engine power that simulates operation in the forest. An engine driven hydraulic and electric power unit will be integrated with the densification equipment along with an engine exhaust gas heat recovery system to heat activate the inherent binder in the forest residues. Using this combined-heat-and-power system will enhance process efficiency and reduce fuel use and emissions. Dense logs will be produced from three different forest slash materials collected from the Blodgett Forest Station, UC Berkeley. The quality of logs produced will be will characterized and a detailed economic analysis will be completed to demonstrate the substantial economic benefits of the BFB process.

Goals / Objectives
The goal of this project is to develop and test the innovative portable low cost densification process, known as Biomass Fuel Blocks Production System (BFB), to significantly lower the handling, storage and transport costs of forest residues as a feedstock for biofuels and power production. The proposed project will adapt the patent pending biomass densification process, known as BBADS, to process the important forest residues of interest to USDA.The objectives of the project will be:To develop a hydraulic power unit for BFB equipment with manifolds, flow control devices by integrating a commercially available engine powered hydraulic pump.To develop a thermal fluid heating system with heat recovery heat exchanger for recovering heat from the engine exhaust.To develop a feeding system to feed chips using commercially available belt conveyors at a rate of 2.5 tons/hour.To integrate all the subsystems on a platform fitted with transport wheels for transportation on roads and inside the forest.To test the portable full-scale BFB system using chips produced from three different forest slash materials to produce good quality logs.
Project Methods
In this project, an engine powered hydraulic power unit will be developed to operate the pusher, gate and door of BFB equipment. Also, a thermal fluid heater using the heat available from exhaust gases of the engine of hydarulic power unit will be developed. In addition, a belt conveyor will be modified to feed chips to the comperssion section of the BFB equipment. Finally, all these subsystems will be integrated with the densification equipment available at Altex to develop a full scale BFB for production of logs from forest residues.After integration of full scale BFB densification equipment, the following performance will be tested and evaluated:1. Feeding, heating, and cooling system performance.2. The overall equipment performance for densified biomass production using forest residues and the portability of the equipment.3. The physical and chemical characteristics of the densified products.

Progress 09/01/15 to 08/31/16

Outputs
Target Audience:We have created a primary market research plan and contacted more than 20 companies invovled in pellet production and forest slash collection. The market research need for identifyingthe entry market and thequestions to be asked to the various stakeholders were prepared and contacted more than 20 stakeholders for developing a commercialization stretegy. Thisinformation was used to prepare a commercialization stretegy report and the same was submitted to our commercialization partner LARTA. The commercialization stretegy report included executive summary, barriers to commercialization, competitive matrix, and commercialization road map. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Dr. Nehru Chevanan attended Commercialization Training Workshop on December 14-16, 2015 at Washington DC, USA. How have the results been disseminated to communities of interest?1. A teleconference was conducted with two scientists from Idaho National Laboratory regarding BFB technology and feeding BFB logs into different reactors for biochemical convresion,thermochemical conversion and biopower applications, on October 31, 2016. 2. A teleconference was conducted with project managers at Bioenergy Technology Office, US Department of Energy regarding BFB technology and also feeding BFB logs into different kinds of reactors, on July 25, 2016. What do you plan to do during the next reporting period to accomplish the goals?1. Complete the development of BFB equipment cooling system and heating system. 2. Integrate all the subsystem with BFB test equipment and process forest residues into logs. 3. Test the quality of logs produced bythe BFB equipment. 4. Demonstrate the BFB system operation at the Altex test facility 5. Prove the economic benefits of the BFB system.
