Oak Ridge National Laboratory (ORNL) demonstrated its continuous commitment to the
Department of Energy’s (DOE) renewable energy and reduced carbon footprint goals through the commissioning of its 60,000 lbm/hr Biomass Steam Plant on July 19, 2012.
The concept was initiated as a TEAM (Transformational Energy Action Management) project and was realized under a $94 million Energy Savings Performance Contract with Johnson Controls, Inc., signed in 2008. This effort is just one single facet to ORNL’s 26 roadmap approach to sustainability.
The Biomass Steam Plant utilizes gasification, the process through which carboncontaining fuel is converted into cleanburning synthesis gas “syngas” at temperatures up to 1,800 degrees Fahrenheit. of the fuel into syngas, leaving only a small portion of fuel to burn completely. The emissions are then filtered leaving no visible trace coming from the stacks.
The plant can convert 70,000 tons of locally supplied wood per year to meet the plant’s baseload steam demand. The steam plant also has the capability to supplement steam during high demand periods with natural gas and oil-fired boilers.
The "syngas" is then routed to an oxidizer, where it burns cleanly, with the hot flue gas directed through a heat recovery steam boiler and then the steam is distributed to buildings across the ORNL campus. This process is cleaner than complete combustion because it uses 20-30 percent of the
O
2 necessary for traditional combustion. This cleaner process is referred to as “starved air” combustion which provides enough heat to pyrolize most
Future Plans and anticipated results:
The Biomass Steam Plant offers exceptional opportunities for laboratory research, including: syngas analysis/research, feedstock testing (wood, switchgrass), corrosion science, waste ash for agriculture, and potential partnerships with universities for study.

Oak Ridge National Laboratory (ORNL) is committed to advancing highway-ready electric vehicles (EVs) and demonstrating their cooperative interaction with the electric grid via the use of renewable power and battery storage. ORNL has installed 25 solar-assisted EV charging stations on its main campus and is currently installing 19 non-solar-assisted charging stations including one DC fast charger. Additionally, 21 employees have acquired plug-in electric vehicles
(Nissan Leafs, Chevy Volts, and a
Prius) and regularly charge them on campus. Research data is being collected and will be published for agency and public benefit.

The charging station (pictured at left) has a complex communications and control system that facilitates the collection and reporting of data
(screenshot example of data reporting at left). These stations include battery storage to more effectively accommodate vehicle charging requirements and to mitigate the impact of electric vehicle charging on local grid infrastructure especially during peak demand periods. In addition, ORNL is managing a portion of Department of
Energy (DOE) project
(www.theevproject.com) to install
125 solar-assisted EV charging stations across Tennessee. These 125 stations have been installed (completed September 30, 2012) and data will be collected and analyzed in 2013.
Key partners in the EV Project are the Tennessee Valley Authority, the Electric Power Research Institute, Nissan, the State of Tennessee, the Knoxville Utilities Board, Nashville Metro Government, the University of
Tennessee, the City of Knoxville and other power distributers in the state.
Future Plans and anticipated results:
Extensive data is being collected and assessed on the project in order to further the success of similar future deployments. The use of battery storage to mitigate fluctuations in demand on the local electric grid may also provide future opportunities to reuse automotive batteries, which may have 60 to 70% life remaining, after they are no longer ideal for vehicle applications. Additionally, the project includes plans to develop metering network interfaces to ensure reliable EV energy data monitoring for research and analysis.
In conclusion, the innovative local, regional, and national collaborative strategies of the EV Project and specifically the solar-assisted charging stations demonstration project is uniquely designed to address both energy and environmental sustainability issues. While increasing the use of energy efficient EVs, reducing reliance on petroleum products, and reducing greenhouse gas emissions. The highly visible charging stations locations maximize community awareness and engagement, all of these factors support the ultimate success of EV use nationwide thereby benefiting the Office of Science, DOE, our nation, and future generations.

Oak Ridge National Laboratory
Oak Ridge National Laboratory (ORNL) has developed its metering program consistent with the Department of Energy (DOE) metering goals. DOE requires that 90% of individual buildings or process electricity must be metered by October 1, 2012, and 90% of steam, natural gas, and chilled water must be metered by October 1, 2015. The pursuit of this requirement has resulted in the design and implementation of a Central Energy
Data System (CEDS) that consolidates multiple management systems and numerous data sources into a single platform that provides significantly enhanced capabilities.
CEDS is vendor agnostic and accordingly it can collect data from most manufacturer's meters and integrate it into a single platform. A common Web browser Graphical User
Interface was also created and it is supported by all Information Technology platforms.
Schneider Electric’s ION Enterprise software was chosen to be ORNL’s partner and provide the CEDS solution. ORNL owned a legacy system previously provided by
Schneider Electric known as PowerLogic SMS.
The CEDS and vendor teams conducted a pilot during FY 2012. The pilot was deemed a success and demonstrated the viable integration of the numerous legacy systems and energy data sources. The Laboratory's energy consumption can now be viewed, trended, and analyzed. CEDS also provides a platform that can be used in partnership with research organizations to gather energy data, provide the tools and capabilities to enhance ORNL’s research in smart grid technologies, electrical vehicle charging infrastructure, energy modeling and peak load management, and efficient building technology.
Facts and Stats:
 CEDS is capable of collecting data from over
300 meters on campus
 220 buildings represent 75% of ORNL’s space and 94% of campus energy use
 CEDS was used to collect power consumption data for supercomputers at ORNL, helping to establish Titan as the #3 ranking system on the
Green500 publication
 A SCADA module provides a means to graphically view live energy consumption data, data analysis and allow future expansion for smart grid deployment to realize the management of energy consumption
 CEDS will be used by the
Utilities staff to manage the electrical distribution network as well as collecting and invoicing energy consumption data to the respective customers
 The CEDS team provided a resource that can also be used by research organizations, leading to submission in a research proposal which was awarded $.5M during FY 2012
Future Plans and anticipated results:
Plans are for CEDS to collect electric power, potable water, chilled water, solar, and electric vehicle charging data; ~200 additional meters will be installed in FY 2013. The system will also collect data gathered by metered devices, such as variable frequency drives and relays. The new system will also provide a common platform for energy sources that will enable lab-wide internal billing and reporting. This system will replace and automate a series of manually managed spreadsheets that are cumbersome and labor intensive as well as provide improved processes for reporting. and analysis of data for both internal use and ORNL’s DOE customer.

Oak Ridge National Laboratory
Oak Ridge National Laboratory (ORNL) uses an integrated approach to water resource management that includes replacing old once-through cooling practices with the latest cooling technologies, installation of the latest water conservation devices, discovery and repair of water leaks, and an implementation of a new site-wide focus by all staff to reduce and conserve water. This approach includes improvements in new construction; renovations and retrofits; operations and maintenance; cross-campus water quality management efforts; and research and development activities.
Numerous water conservation efforts throughout FY 2012 have resulted in significant water use reductions. The Johnson Controls Energy Savings Performance Contract efforts included the installation of low-flow devices in 65 buildings resulting in savings of 12.3 million gallons per year (gpy). Another significant campus modification included the
Biomass Steam
Plant which resulted in the savings of 12 million gpy and a significant campus modification involving the elimination of once-through cooling water in the Central Compressed Air Plant. ORNL requires compressed air for numerous operations and the new Central Compressed Air
Plant is saving 145.6 million gpy.
ORNL’s Leak Elimination Efforts involved the hiring of leak detection experts. These efforts continued in FY 2012 and significant leaks were identified, including a 4-inch water line leak that was repaired and estimated to save 50 million gpy. Additional efforts included the implementation of a water-metering plan that is improving the understanding of ORNL’s water use. There are 33 planned metering locations across campus that will account for over 90% of ORNL’s water use. As of FY 2012, 17 of the 33 facilities have been metered.
Future Plans and anticipated results:
We plan to continue elimination of once-through cooling and identifying and repairing water leaks which will result in a water use intensity of 77. ORNL’s water metering plan will continue to be implemented to characterize our water use and help us identify any future problems with our water distribution system.
Facts and Stats:
 Significant savings were realized in FY 2012 that resulted in a water intensity of 114G/SF, which exceeds the FY 2020 goal (a reduction of 35% relative to FY 2007 baseline)
 Chemical and Materials

The Oak Ridge Leadership Computing Facility (OLCF) team houses, manages, and supports
The Department of Energy (DOE) Office of Sciences’ Cray XK7 Titan supercomputer in
ORNL’s Computational Sciences Building (CSB), a 350,000 square-foot Leadership in Energy and Environmental Design (LEED)-certified facility. Titan is an in-place upgrade of the
Cray XT5 Jaguar system, which claimed the fastest supercomputer rank in November 2009.
In November 2012, Titan was recognized as the fastest supercomputer in the world, with a demonstrated performance of 17.59 PF (quadrillions of floating point operations per second).
This same system is also highly energy efficient, reflected in its award as the #3 most efficient machine on the November 2012 edition of the Green500 list; the system produces more than
2.1 million floating point operations per Watt.
The OLCF is committed to energy and support strategies that not only support efforts at other
Office of Science facilities and in achieving the goals of Executive Order 13514 and the Strategic Sustainability Performance Plan, but they go beyond that to support simulations run on
Titan that provide research and development support for daunting energy challenges. These simulations include: biofuels, nuclear fusion, next-generation nanotransistors, energy efficiency, renewable energy, and fleet/transportation. This research is accurately giving the Office of
Science, DOE, our nation, and future generations the best bang for their buck and an exceptionally competitive edge.
SmartTruck is an example of the advancements in transportation being facilitated by ORNL’s
Jaguar, and now Titan, supercomputers; this effort is evaluating the aerodynamics of 18wheeler (Class 8) long-haul trucks. Jaguar greatly accelerated the development and manufacture of a product that will improve fuel mileage for these trucks, while creating jobs in South
Carolina and Georgia. Jaguar allowed the SmartTruck engineers to break the truck into hundreds of pieces in order to calculate drag with a high degree of accuracy; permitting them to design digitally and then confirm physically. Access to Jaguar led SmartTruck to the holy grail that many manufacturers seek: the ability to substantially reduce or completely bypass the costly and time-consuming process of creating multiple physical prototypes in the design phase of new product development. When it came to
Image 1— Trailers equipped with SmartTruck Systems correlating the computergenerated simulations with physical tests in the field, the
Smart-Truck team scored an
A+. The team's test truck, loaded with prototype components and telemetry, was put through its paces on the world's longest, smoothest concrete landing strip—the 18,000-foot runway at the Kennedy Space Center. The effort has been a success!
Future Plans and anticipated results:
The ability to eliminate the frustration of developing parts through physical experimentation significantly reduces expenses, fueling further innovation. The speed and power of Titan, which combines a CPU processor with a GPU accelerator in a package that is ten times faster than the earlier XT5 design, enables the creation and evaluation of complex models, dramatically accelerating the design process. These benefits will continue to drive the use of the powerful, energy-efficient Titan to reduce energy consumption across industries.
Facts and Stats:
 SmartTruck has the potential to save the United States almost
1.5 billion gallons of diesel fuel annually, reduce CO
2 by 16.4 million tons, and save $4.42 billion in fuel costs
 Titan has 18,688 compute nodes, each with an AMD
16-core microprocessor and an
NVIDIA Kepler GPU. The combined memory footprint between the microprocessor and the GPU is 710 Terabytes. The theoretical peak computational capability is 27.13 petaflops and has broken speed records for processing data. The refrigerant-based ECOphlex cooling system is more than
1000 times more efficient than air–dependent traditional systems, substantially reducing the amount of chilled water used to cool Jaguar and Titan
 Variable frequency drives
(VFDs) and centralized control of the computer room air cooling (CRAC) units provide higher efficiency for air-cooled equipment and energy savings of more than $150,000 per year within the HPC Center
 This same system is also highly energy efficient the CSB’s
(PUE rating of 1.25) makes it almost 32 percent more efficient than its average counterpart at 1.83 (as reported by a Lawrence Berkeley
National Laboratory study of 22 large-scale data centers), a direct result of aggressive energy conservation measures

Oak Ridge National Laboratory
In pursuit of maximizing the efficient use of energy on the Oak Ridge
National Laboratory (ORNL) campus, a wireless system for detecting steam trap performance along 12 miles of steam lines on the site has been successfully tested. The non-invasive sensors check temperature and acoustics and deliver a (good/bad) status signal of performance and loss associated with faulty traps. Data is relayed through a wireless network of repeaters and gateways that alleviate costs normally associated with hardwired data delivery devices. ORNL Facilities and Operations staff use these data to monitor steam trap performance.



A pilot with four wireless sensors have been installed to date
An additional 70 sensors have been purchased and are planned for installation in FY 2013
In FY 2013, a deployment plan will begin development. In
FY 2014, the deployment plan will be delivered and will detail a site wide deployment, with a total of 500 sensors as the initial target
 The installation of wireless sensors and repairing or replacing faulty traps is expected
The installed sensors have proven that the wireless system concept is viable; accordingly, the prototype will continue to install the already procured sensors to fully test the system. The additional sensors will investigate traps requiring monitoring and ensures the already established wireless network can reach the necessary areas. This testing of to result in savings as much as $675,000 per year with a full system deployment the system will also include tangential activities to ensure compliance within the
ORNL Facilities and Operations’ systems. These will include: connecting the system to
Metasys (diagram above demonstrates the data flow in the system); synchronizing the ties Metasys has to the
Wireless Steam Trap Sensors
Central Energy Data System; additionally, there will also be a configuration phase where ORNL will try to
Better account for the physical parameters of the steam traps
(pipe size, rating, etc.). These parameters are the input to an algorithm currently being developed that will roughly estimate losses in the event of a faulty trap.
