Description

First U.S. Demonstration of Biomass Gasification to Internal Combustion Engine

Alaska Power & Telephone (AP&T), in collaboration with Nexterra Systems and GE Energy, the community of Tok and the State of Alaska, and with assistance from Dalson Energy, propose to highlight the U.S. Department of Energys commitment to medium-scale biomass combined heat and power (CHP) technologies through the deployment of a state of the technology 2MWe CHP system in Tok, Alaska, using locally-sourced woody biomass as fuel.

The proposed project combines Nexterras proprietary gasification technology and syngas conditioning system with GE Energys expertise in high-efficiency IC (internal combustion) engines. This will be the first biomass gasification to internal combustion engine project deployed in the U.S. AP&Ts customers will be the first in Alaska to add biomass-generated electricity to their renewable power supply.

AP&T believes that the system will serve as a viable clean alternative to diesel-fueled generators and will catalyze the replication of renewable community-scale biomass CHP in rural communities, municipalities and institutions throughout Alaska, and across North America.

Alaska Power & Telephone has applied for a DOE grant of $10M from the National Energy Technology Laboratory, and will raise another $10M in state and private funding.

THE TECHNOLOGY
Nexterra uses a fixed-bed updraft gasification system which has been commercially proven for converting biomass into synthesis gas or syngas
which is a clean-burning combustible gas that can be used like natural gas to generate electrical power and heat. The proposed system in Tok,
Alaska will combine Nexterras commercial gasification technology with its newly developed syngas conditioning system and a GE Jenbacher gas
engine. The combination will create a modular biomass combined heat and power (CHP) plant, enabling the community of Tok to economically
self-generate renewable heat and power.

IMPACT ON RENEWABLE POWER INDUSTRY
Biomass is a carbon neutral fuel that can be used to produce low-cost renewable heat and power in place of more expensive fossil fuels.

Despite significant forest lands and expensive diesel fuel, the biomass energy industry in Alaska is still in its infancy. This proposed project will demonstrate the feasibility of biomass for thermal and electricity generation and its success could lead to replication in other communities and institutions throughout Alaska.

This project will use woody biomass from the State of Alaska forest land leased to AP&T for this project through a 25-year, 27,000-acre sustained yield harvest plan. The system will convert approximately 12,500 tons of biomass residuals per year to heat and power that will use approximately 625 acres/year at 20 tons/acre, or a total of 12,500 acres over 20 years. This amounts to less than half the biomass available from the leased parcel of state forest land.
