Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

 


Electrically Conductive Paste Provides Life Cycle Cost Savings for [Wind] Turbine Electrical Connections

Wind Systems Magazine, Aug. 2014, by Tom Gibson.
http://www.windsystemsmag.com/article/detail/706/electrically-conductive-paste-provides-life-cycle-cost-savings-for-turbine-electrical-connections

"...manufacturers are also standardizing wind turbine systems to make them similar to other electrical systems familiar to maintenance technicians, using established modular industrial connectors for plug-and-play convenience. Plug-in connectors are used when possible, eliminating the time required by traditional mechanical bolt-type connectors. But are the manufacturers and installers taking a serious look at protecting these electronics?

Perhaps the answers lie in looking at how electrical connections on other types of equipment around the world are protected from moisture and corrosion. They often benefit from the use of electrically conductive paste on connections, extending their life span, enhancing safety, and raising their electrical efficiency

"Energy-efficient pumps, intelligent pump-control logic and variable-frequency drives help the company process more minerals and cut energy use."

Advancing Microturbine Technology: A Small Package, Turbocharged

Cogeneration & On-Site Power Production, Jul/Aug 2014, by David Dewis.
http://www.cospp.com/articles/print/volume-15/issue-4/features/advancing-microturbine-technology-a-small-package-turbocharged.html

"Advanced microturbine technology with an intercooled and recuperated (ICR) cycle can deliver efficiency and low emissions at a competitive price. Now in the testing stage, ICR microturbines will be the foundation for the next generation of clean and efficient distributed generation, writes David Dewis."

Energy, Exergy or Economy? Figuring the Benefits of CHP

Cogeneration & On-Site Power Production, Jul/Aug 2014, by Jacob Klimstra.
http://www.cospp.com/articles/print/volume-15/issue-4/features/energy-exergy-or-economy-figuring-the-benefits-of-chp.html

"For many readers familiar with the concept of energy balances and tools such as Sankey diagrams, background knowledge of thermodynamics is often lacking. That might not be an issue for a practical user, but such knowledge can be of utmost importance when designing installations and when promoting the benefits of cogeneration for policymakers. In a series of articles, Jacob Klimstra discusses the energy balance of cogeneration installations."

Evaluating Air Compressor Cooling Systems

Compressed Air Best Practices, Aug. 2014, by Nitin G. Shanbhag.

"As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important."

SnoPUD Takes a Fresh Approach to Energy Storage

Northwest Public Power Association Bulletin, Aug. 2014, by Neil Neroutsos. [Open and Scroll/Jump to page 14 of the PDF.]

"Later this year, Snohomish County Public Utility District plans to deploy an innovative energy storage system that aims to transform the marketplace and how utilities manage electric grid operations. The PUD, and its principal partner 1Energy Systems, will install the Modular Energy Storage architecture (MESA) at multiple utility substations. The system will provide a standard, non-proprietary, and scalable approach to energy storage."

Dealing With Motor Failures: Common Causes and Solutions

Maintenance Technology, Aug. 2014, by Thomas H. Bishop.

"If you want to make a plant manager’s day, just say: “Production’s down because a motor failed.” Fortunately, such situations can usually be overcome with some relatively simple techniques and straightforward solutions to protect the bearings and stator windings. These two vulnerable components are root causes of the vast majority of motor failures."

Hawaii Energy Offers State’s First Energy Efficiency Auction

Air Conditioning/Heating/Refrigeration News, Sept. 11, 2014.
http://www.achrnews.com/articles/127594-sept-11-2014-hawaii-energy-offers-states-first-energy-efficiency-auction

"Hawaii Energy, the ratepayer-funded energy conservation and efficiency program for Hawaii, Honolulu, and Maui counties, is launching the Hawaii Energy Efficiency Auction. The auction is an open call for contractors, developers, energy efficiency solution providers, energy service companies (ESCOs), energy vendors, and property managers to submit qualified energy efficiency projects to compete for up to $2.1 million in incentive funds to offset project costs."

Australian 3D Printed Solar Cells Getting Closer to Commercial Reality

"The CSIRO [Commonwealth Scientific and Industrial Research Organisation] has said that printable solar cells are near to being commercialised, with several firms interested in bringing the technology to market."

Integrated Thinking at the Hilton Foundation: Combining Architecture with Operations

Business Energy, Jul/Aug.\ 2014, by Carol Brzozowski.
http://www.distributedenergy.com/DE/Articles/26496.aspx

"The Hilton Foundation building [Agoura Hills, CA], designed to exceed the US Green Building Council’s Leadership in Energy & Environmental Design (LEED) Platinum certification, is significantly more efficient in its use of energy and water than most LEED Platinum office buildings. A large contributor toward achieving net-zero energy is the design of the building’s integrated envelope and building cooling and heating systems."
