Energy-Saving Melting and Revert Reduction (E-SMARRT): Energy Efficiency Instrumentation (open access)

Energy-Saving Melting and Revert Reduction (E-SMARRT): Energy Efficiency Instrumentation

As with any manufacturing operation, the metalcasting processes have several sources of variation. Additionally, the metalcasting industry routinely produces a wide variety of complex shaped components, which often exacerbates the problem of determining the source of variation. The goals of this project were to develop better tools and strategies to collect and manage process and product information. Based on industry feedback, five areas were selected based on the amount of variation caused by this source or the potential for improvement in terms of energy, emissions and competitiveness. These five areas were: 1. Heat Treatment Control Strategies 2. Semi-Automated Grinding 3. Surface Mapping Software 4. Study of Impact of Repairs via Weld Gouges 5. Rapid Pattern Making Machine This project collectively looked at areas of the steel casting production process which could help reduce the rework, scrap and energy consumption required. Through these efforts, casting producers are better equipped to control their processes and specify processes that better meet their customers’ needs.

Final Technical Report (open access)

Final Technical Report

This report summarizes the successful results of our SunShot project, Advanced Low-Cost Receivers for Parabolic Troughs. With a limited budget of $252K and in only 12 months, we have (1) developed validated optical and thermal models and completed rigorous optimization analysis to identify key performance characteristics as part of developing first-generation laboratory prototype designs, (2) built optical and thermal laboratory prototypes and test systems with associated innovative testing protocols, and (3) performed extensive statistically relevant testing. We have produced fully functioning optical and thermal prototypes and accurate, validated models shown to capture important underlying physical mechanisms. The test results from the first-generation prototype establish performance exceeding the FOA requirement of thermal efficiency >90% for a CSP receiver while delivering an exit fluid temperature of > 650 °C and a cost < $150/kWth. Our vacuum-free SunTrap receiver design provides improvements over conventional vacuum-tube collectors, allowing dramatic reductions in thermal losses at high operating temperature.

Subtask 4.24 - Field Evaluation of Novel Approach for Obtaining Metal Emission Data (open access)

Subtask 4.24 - Field Evaluation of Novel Approach for Obtaining Metal Emission Data

Over the past two decades, emissions of mercury, nonmercury metals, and acid gases from energy generation and chemical production have increasingly become an environmental concern. On February 16, 2012, the U.S. Environmental Protection Agency (EPA) promulgated the Mercury and Air Toxics Standards (MATS) to reduce mercury, nonmercury metals, and HCl emissions from coal-fired power plants. The current reference methods for trace metals and halogens are wet-chemistry methods, EPA Method (M) 29 and M26A, respectively. As a possible alternative to EPA M29 and M26A, the Energy & Environmental Research Center (EERC) has developed a novel multielement sorbent trap (ME-ST) method to be used to sample for trace elements and/or halogens. Testing was conducted at three different power plants, and the results show that for halogens, the ME-ST halogen (ME-ST-H) method did not show any significant bias compared to EPA M26A and appears to be a potential candidate to serve as an alternative to the reference method. For metals, the ME-ST metals (ME-ST-M) method offers a lower detection limit compared to EPA M29 and generally produced comparable data for Sb, As, Be, Cd, Co, Hg, and Se. Both the ME-ST-M and M29 had problems associated with high blanks for Ni, Pb, Cr, …

Acoustic Modeling for Aqua Ventus I off Monhegan Island, ME (open access)

Acoustic Modeling for Aqua Ventus I off Monhegan Island, ME

The DeepCwind consortium, led by the University of Maine, was awarded funding under the US Department of Energy’s Offshore Wind Advanced Technology Demonstration Program to develop two floating offshore wind turbines in the Gulf of Maine equipped with Goldwind 6 MW direct drive turbines, as the Aqua Ventus I project. The Goldwind turbines have a hub height of 100 m. The turbines will be deployed in Maine State waters, approximately 2.9 miles off Monhegan Island; Monhegan Island is located roughly 10 miles off the coast of Maine. In order to site and permit the offshore turbines, the acoustic output must be evaluated to ensure that the sound will not disturb residents on Monhegan Island, nor input sufficient sound levels into the nearby ocean to disturb marine mammals. This initial assessment of the acoustic output focuses on the sound of the turbines in air by modeling the assumed sound source level, applying a sound propagation model, and taking into account the distance from shore.

The commercial development of water repellent coatings for high voltage transmission lines (open access)

The commercial development of water repellent coatings for high voltage transmission lines

The purpose of the Cooperative Research and Development Agreement (CRADA) between UT-Battelle, LLC and Southwire Company was to jointly develop a low cost, commercially viable, water-repellant anti-icing coating system for high voltage transmission lines. Icing of power lines and other structures caused by freezing rain events occurs annually in the United States, and leads to severe and prolonged power outages. These outages cause untold economic and personal distress for many American families and businesses. Researchers at the Department of Energy?s Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee have previously developed a set of superhydrophobic coatings with remarkable anti-icing properties that could potentially be sprayed or painted onto high-tension power lines and pylons. These coatings drastically reduce ice accumulation on these structures during freezing rain events. The project involved obtaining technical input, supplies and test high voltage cables from Southwire, along with the joint development of anti-icing coating techniques, which would result in a commercial license agreement between Southwire and ORNL, and potentially other companies requiring water repellent anti-icing coatings.

Federal Real Property: GSA Should Clarify Savings Goals for the National Broker Contract Program

A letter report issued by the Government Accountability Office with an abstract that begins "While the General Services Administration (GSA) has used the National Broker Contract (NBC) program to assist with the agency's lease portfolio, it is unclear whether the program has resulted in the rental rate cost savings that GSA anticipated when proposing the program. GSA officials have stated that brokers should be able to obtain lower rental rates than in-house staff because brokers have greater market expertise and in addition are able to credit a portion of the broker's commission to the rental rate. In 2012, when GSA attempted to compare rental rates negotiated by brokers with those negotiated by in-house staff, the agency not only found little difference between the two, but also stated that the data were insufficient to conduct a meaningful comparison. In April 2013, GSA began requiring the use of a different market rent data report --"Bullseye"-- which includes market information, analysis, and insight regarding the local submarket. Officials said this new data would improve their ability to compare rental rates negotiated by brokers to market rental rates, but will likely not allow officials to determine whether brokers are negotiating better deals than in-house …

Ionic Liquids as Novel Lubricants and /or Lubricant Additives (open access)

Ionic Liquids as Novel Lubricants and /or Lubricant Additives

This ORNL-GM CRADA developed ionic liquids (ILs) as novel lubricants or oil additives for engine lubrication. A new group of oil-miscible ILs have been designed and synthesized with high thermal stability, non-corrosiveness, excellent wettability, and most importantly effective anti-scuffing/anti-wear and friction reduction characteristics. Mechanistic analysis attributes the superior lubricating performance of IL additives to their physical and chemical interactions with metallic surfaces. Working with a leading lubricant formulation company, the team has successfully developed a prototype low-viscosity engine oil using a phosphonium-phosphate IL as an anti-wear additive. Tribological bench tests of the IL-additized formulated oil showed 20-33% lower friction in mixed and elastohydrodynamic lubrication and 38-92% lower wear in boundary lubrication when compared with commercial Mobil 1 and Mobil Clean 5W-30 engine oils. High-temperature, high load (HTHL) full-size engine tests confirmed the excellent anti-wear performance for the IL-additized engine oil. Sequence VID engine dynamometer tests demonstrated an improved fuel economy by &gt;2% for this IL-additized engine oil benchmarked against the Mobil 1 5W-30 oil. In addition, accelerated catalyst aging tests suggest that the IL additive may potentially have less adverse impact on three-way catalysts compared to the conventional ZDDP. Follow-on research is needed for further development and optimization of IL …

Maritime Security: DHS Could Benefit from Tracking Progress in Implementing the Small Vessel Security Strategy

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) and its components--such as the U.S. Coast Guard and Customs and Border Protection (CBP)--have started or completed initiatives to address small vessel security risks, but DHS is not tracking the progress being made to address action items in the Small Vessel Security Strategy (SVSS) Implementation Plan. "Small vessels" are characterized as any watercraft--regardless of method of propulsion--less than 300 gross tons, and used for recreational or commercial purposes. DHS component officials GAO met with identified examples of key initiatives that they have completed or have under way to enhance small vessel security, including an initiative to help CBP better track small vessels arriving from foreign locations and another to assist the Coast Guard in assessing and monitoring small vessel launch sites. Although the SVSS Implementation Plan states that DHS is to assess and update the plan, DHS has not determined the progress its components and other relevant stakeholders--such as the Department of Defense--are making in completing the action items and has no current plans to do so. DHS officials stated that this is due, in part, to budget constraints that …
