RePower Humboldt: Biomass-Fired Fuel Cell Power System

The 175 kW biomass-fired fuel cell power system being installed at the Blue Lake Rancheria is nearly complete. The Proton Power gasifier has been installed and gone through initial start-up procedures, including heating up the gasifier to temperature and running the flare. The gas compression system (rotary claw compressor, syngas ballast tank, and reciprocating compressor) has been tested and the control strategy has been confirmed. The Xebec pressure swing adsorption (PSA) hydrogen purifier is installed and ready for testing, and the Ballard PEM fuel cell is in place and has undergone pre-commissioning. Most of the peripheral systems (biomass feed, control, fire alarm and life safety, cooling, and ventilation) are complete or very near completion. Our next steps will be to obtain a fuel with a moisture content no greater than 40% (wet basis); begin making syngas; test and confirm syngas quality; and then fully commission the PSA and fuel cell system, as well as the fully integrated system. We submitted a draft final report to the CEC in March, but work on the system will continue over the next few months until we achieve full system operation and performance testing. Following these activities a revised final report will be submitted.
