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.

"California vineyard uses AODD [air-operated double-diaphragm]pumps for 6,000-gallon tanks to achieve up to 60 percent savings in energy and operating costs."

Pump System Optimization in Pulp & Paper: High-Value Target Applications

Pumps & Systems, July 2016, by Mike Pemberton.

"In most pulp and paper applications, energy and unscheduled maintenance are two of the largest components of ownership cost. For this reason, improving pump efficiency is key to pump system optimization. Although certain mechanical and control modifications can improve reliability, selecting the best hydraulic fit is an often overlooked approach to system optimization. Energy and reliability are two sides of the same coin: A good rule of thumb is that where there is excess energy beyond what is required to move fluid through the pipes, there will also be unreliability."

A Simplified Method of Determining the Efficiency of a Motor-Driven Centrifugal Pump

Pumps & Systems, July 2016, by Robert X. Perez.

"A common concern in processing plants is determining the pumping health—or efficiency—of centrifugal pumps. As pump impeller seals wear as a result of erosion and corrosion mechanisms, tight internal clearances open up and allow fluid to recirculate internally, gradually degrading performance. As wear progresses, a centrifugal pump will eventually become unable to perform its intended function. Periodically monitoring pump performance allows end users to identify internal degradation before a serious loss of capability occurs."

Commissioning and Design for 2016 Olympics

ASHRAE Journal, Jul 2016, by Ross D. Montgomery and Walter R. Lenzi.

"Beginning in 1994, the International Olympic Committee began to require environmental awareness as part of all Olympic Games. Over the years, the emphasis on sustainability grew, and the Rio 2016 Olympic Games in August is the latest example of the benefits gained by using these strategies. ASHRAE members and student members are a part of this high-profile project, as they provided commissioning and HVAC&R design services, especially at the Olympic Park. This venue is where most events will occur in Barra da Tijuca, located 21 miles (34 km) south of Copacabana beach."

Eugene Evaluating Safety of LED Lights

"Eugene city officials are evaluating the light emitted by new LED streetlights after the American Medical Association issued an official policy statement that it can be harmful to a person’s health."

New Heat Pump Water Heater Changes the Game

Northwest Energy Efficiency Alliance, July 2016.
http://neea.org/neea-newsroom/press-releases/press-release-detail/2016/07/05/new-heat-pump-water-heater-changes-the-game

"Today, A. O. Smith, the largest manufacturer and marketer of water heaters in North America, introduced a dramatically efficient new model of heat pump water heater. Already three times more efficient than a standard electric water heater, A. O. Smith engineers refreshed the Voltex line to improve energy efficiency benefits and performance for homes in all climates, including homes that routinely deal with cold weather."

Energy-Water Nexus Issues Heighten in the Face of Climate Change

ACEEE, Jul 8, 2016, by Steven Nadel.
http://aceee.org/blog/2016/07/energy-water-nexus-issues-heighten

"ACEEE and many others have noted the importance of the nexus between energy and water issues. Energy is used to move, treat, and heat water. Water is vital for producing energy, such as for cooling electric generating plants. Insufficient water availability can increase energy use for pumping and decrease energy production. Flooding can damage both energy and water systems. And there are many opportunities to promote both energy and water efficiency at the same time."

Farm to Fleets: Manure Helps Chicago Startup Build Natural Gas Network

Chicago Tribune, Mar. 2016, by Ally Marotti.
http://www.chicagotribune.com/bluesky/originals/ct-ampcng-opens-more-filling-stations-20160317-story.html

"Chicago startup AmpCNG launched at a farm in northwest Indiana that converted cow manure to renewable natural gas. Nearly five years later, that manure from Fair Oaks Farm is still a core part of the West Loop-based startup’s business. But its reach has grown. It now owns and operates 19 compressed natural gas, or CNG, stations in eight states, fueling the increasing number of vehicles that operate on the resource."

Special Report: "What is the state and future of the electric utility industry? That’s a broad topic, much discussed and debated. This special report takes a unique approach to getting a handle on our present and where we’re heading."

Pacific Northwest National Laboratory Technologies Get Boost Toward Market

Tri-City Herald, Jul 2, 2016.
http://www.tri-cityherald.com/news/local/pacific-northwest-national-lab/article87393392.html

"The Department of Energy has awarded PNNL in Richland about $4.4 million of a total $12 million given to national laboratories from the Technology Commercialization Fund of DOE’s Office of Technology Transitions. PNNL’s winning projects, all nearing commercialization, include:

▪  A solar system that converts natural gas into hydrogen for fuel cell vehicles.
▪  Making fertilizer from coal fly ash, a byproduct of coal-fired power plants.
▪  Self-powered acoustic fish-tracking tags for evaluating fish passage at dams.
▪  Material manufacturing techniques to make more durable, longer-lasting components for dams.
▪  A method to join aluminum parts made of different thicknesses and alloys for car manufacturing....and more."
