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.

 


Biofuel Technology Goes Mobile [Pyrolysis]

WSU College of Agricultural, Human, and Natural Resource Sciences (CAHNRS), Press Release, Jun. 2014.
http://news.cahnrs.wsu.edu/2014/06/11/biofuel-technology-goes-mobile/

"Scientists like Manuel Garcia-Perez and his graduate students, who study biosystems engineering at Washington State University, are helping to nurture the emerging biofuels industry by developing pyrolysis technologies. Garcia-Perez and Geraldo Ferreira-David of Brazil calculate material entering and exiting the pyrolysis system."

How to Save 2 Million Barrels of Oil Per Day

American Council for an Energy-Efficient Economy (ACEEE), June 2014, by Siddiq Khan.
http://www.aceee.org/blog/2014/06/how-save-2-million-barrels-oil-day

Provides a summary of efforts to increase fuel savings in trucks through continued promotion of fuel efficiency and greenhouse gas emissions standards for medium- and heavy-duty vehicles and engines built for the 2014 to 2018 model years and to extend the EPA and NHTSA program beyond 2018.


Being Radiant: Planning In-Slab Hydronic Heating and Cooling

The Construction Specifier, June 2014, by Ryan Westlund.

"Radiant systems are ideally suited to a broad range of commercial applications and achieve best results when combined with other energy-efficient solutions in tight building structures. While radiant heating-only systems have a long history in conditioning both commercial and residential structures, radiant cooling is fairly new to North America. Early adopters of these systems were located primarily in arid regions. Mainstream acceptance required the development of more advanced controls, coupled with compelling evidence of reduced energy consumption for the built environment."

Preventive Maintenance for Profit

Plant Services, May 2014, by John Kravontka.
http://www.plantservices.com/articles/2014/preventive-maintenance-for-profit/?show=all

"The challenge facing manufacturers is how to implement a maintenance program that will provide immediate return. It can take as many as five or 10 years to train maintenance staff and introduce programs for them to carry out."

Determine Total Cost of Ownership When Selecting Medium-Voltage Drives (Part 2)

Pumps & Systems, Jun. 2014, by Mark W. Harshman.
http://www.pump-zone.com/motors/june-2014-determine-total-cost-ownership-when-selecting-medium-voltage-drives

"Part One of this two-part series (Pumps & Systems, May 2014) explained how factors other than initial purchase price work together to generate the total cost of ownership (TCO) for medium-voltage variable frequency drives (VFDs). Part Two discusses what creates high reliability in a medium-voltage VFD."

Designing for Comfort & IAQ: Air Distribution per ASHRAE 55 and 62.1

The Construction Specifier, June 2014, by Jim Aswegan and David Pich.
http://www.constructionspecifier.com/masterformat/designing-for-comfort-iaq-air-distribution-per-ashrae-55-and-62-1/

"The goal of a room air distribution system is to provide thermal comfort and a healthy living environment for occupants in the space. American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) 55-2013, Thermal Environmental Conditions for Human Occupancy, and ASHRAE 62.1-2013, Ventilation for Acceptable Indoor Air Quality, provide designers with the guidance to optimize health and comfort in building spaces. Many codes, along with the U.S. Green Building Council’s (USGBC’s) Leadership in Energy and Environmental Design (LEED) 2009 program, require compliance with these ASHRAE Standards."

The Next Generation of U.S. Energy Efficiency Motor Regulations

Pumps & Systems, Jun. 2014, by John Malinowski.
http://www.pump-zone.com/motors/june-2014-next-generation-us-energy-efficiency-motor-regulations

"Several years ago, the U.S. Department of Energy (DOE) conducted a technical study about how to raise “small” motors’ efficiency levels. After years of study, the Small Motor Rule was passed, covering General Purpose two-digit NEMA frame (and IEC equivalents), single- and three-phase, 1/4- through 3-horsepower motors in open enclosures. Totally enclosed, fan-cooled (TEFC) motors are not included. This regulation will take effect on April 9, 2015."

Grounding Rings Rescue Paper Mill’s Bearings

Maintenance Technology, May 2014.
http://www.maintenancetechnology.com/2014/05/grounding-rings-rescue-paper-mills-bearings/

"At a paper mill in the Midwest, every new motor that is to be controlled by a variable frequency drive (VFD) must be tested. If shaft voltages are found, the motor must be equipped with an AEGIS® Bearing Protection Ring to divert damaging currents to ground. The plant’s electrical reliability engineer established this money-saving specification after many years of frustration from recurring bearing failures."

Eccentric Disc Pumps Create Product Recovery Cost Savings

Pumps & Systems, Jun. 2014, by Wallace Wittkoff.
http://www.pump-zone.com/pumps/june-2014-eccentric-disc-pumps-create-product-recovery-cost-savings

"Targeted product recovery in hygienic manufacturing reduces waste, decreases operating costs and maximizes the use of raw materials and end products."

Effect of the Type of Bean, Processing, and Geographical Location on the Biodiesel Produced from Waste Coffee Grounds

Energy Fuels, 2014, by Rhodri W. Jenkins, et. al.
http://pubs.acs.org/doi/pdf/10.1021/ef4022976

"Waste coffee grounds offer a viable waste feedstock for biodiesel production. Approximately 8 million tonnes of coffee are produced globally each year and contain up to 15 wt % lipid, of which the glyceride portion is predominantly made up of palmitic, stearic, oleic, and linoleic acids. In this investigation, the variation in the oil content, saponifiable lipids, and lipid profile according to the regional location and processing or brewing techniques was assessed. A number of key fuel properties were also investigated."
