Project Brochure
The Next Generation of Industrial Gasification Systems
 
ORNL

ORNL Gasification System
Customer:US Department of Energy and Johnson Controls Inc. for Oak Ridge National Laboratory
Location:Oak Ridge, Tennessee
Facility Type:DOE Energy Research Laboratory and Bioenergy Science Centre
Application:Biomass plant to provide heat for the ORNL campus
Nexterra Scope of Work:Nexterra will supply the complete gasification system.

Highlights
Capacity:60,000 lbs/hr of low pressure steam for district heating
Fuel:Locally sourced wood residue with 3+ day storage in dual-bin system
Fuel moisture content:10 - 50%
Fuel source:Local mills

Benefits
Fuel Cost Savings:$5-7 million per year
Greenhouse Gas Reduction:20,000 tons/yr (estimated)
Reduced Reliance on Fossil Fuels:Enables ORNL to shut down four fossil fuel fired boilers
Local Economy:Supports local business by using locally sourced wood waste

Process

  • 3 gasifiers convert wood biomass to combustible syngas.
  • Clean syngas is burned in the oxidizer.
  • The hot flue gas is directed through a steam boiler.
  • The steam is then distributed to all ORNL campus buildings.
  • The ESP further cleans flue gas before releasing it out the stack.

ORNL

Commissioning is underway at Nexterra's biomass gasification system at the Oak Ridge National Laboratory. The system is the cornerstone of an $89 million dollar contract Johnson Controls received from the DOE’s Transformational Energy Action Management (TEAM) Initiative to undertake a range of energy conservation measures at ORNL, the flagship energy research facility in the US.

"This project showcases the opportunity for public institutions to partner with the private sector to deploy innovative clean energy technologies that can make us more energy independent. We have a terrific partner in Johnson Controls and a proven gasification technology leader in Nexterra."
- Dr. Thom Mason, Director, Oak Ridge National Laboratory
