How To Build A Wood Gasifier
Inspiring Investment
Free of charge to CESA, the 2009 report focused on conversion technologies with capacities of less than 5 megawatts (MW) or 50 million Btu per hour. Primary applications considered were thermal, combined-heat-and-power (CHP), and district heating. The report analyzed biomass availability, strengths and weaknesses of both technologies, system economics, and included an assessment of their commercial statuses, as well as inventories of suppliers of both technologies.Not surprisingly, the study found that direct combustion systems for heat, power or CHP are available commercially from a number of manufacturers. Gasification systems, however, showed different and more diverse results. Close-coupled gasification systems, where the syngas is burned directly for space heat, drying or to produce steam, were already commercially available from manufacturers. But what Haase calls two-stage gasification, where the syngas is conditioned for tar and particulate matter removal before use in a genset or gas turbine, were largely still in development with a number of technologies in the demonstration phase.
In light of those findings and others, NREL concluded its study with three important recommendations: entities wishing to support the development of gasification applications and technologies should consider funding demonstration projects of near-commercial technologies in their states; a central clearinghouse of the market potential for small- and community-scale biomass direct combustion and gasification systems should be commissioned; and a national assessment of the market potential for small- and medium-scale systems that is searchable online should be created and maintained. “For many states, biomass has been a challenge for our members to figure out a strategy and program approach that really evaluates the efficiency of biomass conversion,” says Mark Sinclair, executive director of CESA, which is made up of major state-level programs that invest public dollars in renewable energy. He added that the study confirmed what CESA already knew: state clean energy programs have an important role in supporting research and development to move forward with biomass gasification and more efficient direct combustion technologies.
Thus, NREL’s recommendation that entities supportive of gasification technologies fund demonstration projects was taken seriously by a number of CESA members. “Several of our states relied on that recommendation for demonstration projects to direct some funding into supporting biomass conversion technology acceleration,” Sinclair says. The Alaska Renewable Energy Fund invested $2 million in a 400-kilowatt biomass-fired Organic Rankine Cycle combined-heat-and-power plant that is scheduled for start-up this fall, he says. Massachusetts and Wisconsin have referenced the report in funding considerations, he adds, and the California Energy Commission took it as confirmation that the money it had already invested in biomass conversion technologies through its Public Interest Energy Research program over the past decade was crucial to development. “They say while the NREL report didn’t spur new activity, it basically confirmed the need for their continued research in support of future gasification advancement activity,” Sinclair says, adding that California has two demonstration-scale two-stage gasifiers currently operating. Both were developed, however, before NREL released its report.

The Missoula City-County Health Department has granted the University of Montana an air quality permit to build a $16 million biomass gasification boiler on campus. The department concluded Wednesday that UM's proposal to burn wood meets all ambient
The gasification system's twin will be installed at a landfill in Catawba County, NC, and will run on wood diverted from the landfill, according to Nexterra CEO Jonathan Rhone. Both systems will be paired with a GE Jenbacher engine, a technology to
UM wants to build a synthetic gasification system that turns wood chips into heating fuel (see related story). It would produce about 1.5 megawatts of electricity, which would be used on the university campus. Stoltze Land and Lumber's project would
Finally, the advisory council is concerned that the biomass gasification plant undermines the efforts Missoula citizens have made "as individuals to improve air quality by complying with restrictions on wood-burning stoves, fireplaces, etc.
UM's proposed wood gasification boiler is the equivalent of 560 pellet stoves or roughly 127 woodstoves, say health department officials. Still, that will represent less than 1 percent of the particulate matter released into the Missoula Valley airshed
