Key Business Drivers for Renewable Community Energy
•
Demonstrate community leadership
•
Reduce energy costs & reliance on
fossils
–
Economies of scale and scope
•
Lower greenhouse gas emissions
•
Minimize carbon taxes/offset costs
•
Meet state or local government
mandates
•
Create local jobs using local fuels

Why Biomass?
•
•
•
•
•
Renewable and carbon neutral
Substitution for fossil fuels reduces GHG emissions
Locally sourced fuel such as locally produced wood residue, pine beetle kill,
municipal tree trimmings, recycled construction and demolition waste etc.
Dispatchable (base-load capable) source of energy
Lower cost than natural gas or oil

System Packages for On-Site Heat and Power
Small Scale Turn-key Heat & Power Systems
•  Steam & hot water systems (20 – 120 MMBtu/hr)
•  Direct-fired thermal systems to convert boilers from fossil fuel to syngas
•  Steam power or steam Co-generation (2 –10 MW)
•  Syngas to internal combustion engine CHP systems (2 – 10 MW)
•  Fuels – wood (commercial); biosolids (development)

A New Approach – Biomass for Community District Energy
Traditional Approach
Conventional Biomass
(Large Combustion)
Centralized, rural, industrial,
low efficiency, higher
emissions, capital intensive
Constrained by scale = fuel
disruption, fuel risk, financing
permitting, community
acceptance
Disruptive
Next Gen Biomass
(Small Gasification)
7 │ Private & Confidential
Small plants, urban,
institutional, high efficiency,
ultra low emissions,
community friendly
Constrained by technology
response comparable to
other renewables (e.g. solar,
wind)
Key Project Considerations for a Biomass Project
•
Air emissions
•
Dust and odor
•
•
Noise attenuation
Fuel truck traffic
•
Building aesthetics and design
•
Community acceptance
