At the request of the Clean Energy States Alliance (CESA), the National Renewable Energy Laboratory prepared this market assessment of gasification and direct combustion technologies that utilize solid biomass to generate heat, power, or combined heat and power (CHP) for small to medium-scale applications. Solid biomass refers to primarily wood and agricultural resources. The report contains the following:

• An overview of solid biomass resources in the United States.

• Description of gasification and combustion conversion technologies that utilize solid biomass to generate heat, power, and CHP.

• Discussion of the strengths and weaknesses of gasification and combustion technologies.

• Assessment of the commercial status of gasification and combustion technologies.

• Summary of gasification and combustion system economics.

• Market potential for small- to medium-scale gasification and combustion systems.

• An inventory of direct combustion system suppliers.

• An inventory of gasification technology companies.
