Renewal Energy Showcase: Biomass Gasification System

Scope

Upgrades existing natural gas steam plant to a wood gasification biomass plant

Biomass plant integrated with existing plant for one integrated facility

Upgrades outdated infrastructure in existing plant

Upgrades existing steam distribution system

Woody biomass will be sourced within a 50 mile radius

Benefits

Reduces fossil fuel consumption by over 80%!

Major renewable energy utilization

Integrated with ORNL Biomass and Syngas research initiatives

Energy Conservation Showcase: EERE’s Super Boiler Technology

Scope

Elimination of over 1.5 miles of steam piping to Melton Valley

Johnson Controls and ORNL worked together to incorporate EERE’s Super Boiler Technology in the new Melton Valley Steam Plant

Benefits

Super Boiler operates at up to 94% efficiency

NOx and CO emissions < 5ppm, extremely “clean”

Integrated M&V approach provides on-going research information

Other Energy Conservation Measures

ECM 3.1 Building Management System Upgrades

ECM 3.2 Advanced Metering and Energy Awareness “Smart Meters” will integrate with ORNL’s energy management system

Incorporates lab-wide program for energy awareness and sustainability education

ECM 4.1 Building Mechanical Upgrades

ECM 5.1 Lighting Utilizes DOE scotopic and photopic research where applicable

ECM 13.1 Water Conservation Reduces domestic water consumption by over 50%

ECM 13.2 Compressed Air Cooling System Eliminates over 100 million gallons annually of once-through cooling water

Reduces site water consumption by 14%

It takes the entire “bundle” to meet the TEAM Initiative!
