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.

Regulation of Commercial Fan Efficiency: An In-depth Exploration of the Department of Energy’s Fan and Blower Rule

Business Energy, Jul/Aug 2016, by Trinity Persful.

"Fans consume 14% of the electricity purchased by industrial and commercial buildings. Yet, fan efficiency has escaped the attention of those who design efficiency into the air systems they specify. That is about to change. The US Department of Energy (DOE) will publish their proposed rule this year covering fans from 1 to 200 horsepower. This new regulation will determine compliance at the design point of the fan."

Microgrid & Microturbine Power Trends

Business Energy, Jul/Aug. 2016, Lyn Corum.

"There are interesting developments happening with microgrids these days. Utilities are adding them to stabilize their grids, and communities are developing a peer-to-peer consumer energy trading system to buy and sell electricity generated by their solar systems."

Update on U.S. Fan Energy-Efficiency Regulation

Heating, Piping, Air Conditioning Engineering, Aug. 2016, by Anthony (Tony) Rossi and Michael Wolf.

"Progress to date and future direction of efforts to reduce fan power consumption."
References ANSI/ASHRAE/IES 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings and AMCA 205, Energy Efficiency Classification for Fans.

Premium Power Drive Systems

Heating, Piping, Air Conditioning Engineering, Aug. 2016, by Rob Boteler.

"Increasingly in industrial and commercial HVAC applications, electric motors are being combined with power converters to form premium power drive systems (PPDS). When used in variable-flow applications, PPDS can deliver savings unmatched by mechanical speed/flow-control systems."

The Intricacies of Pyrolyzer Furnace Design

Biomass Magazine, August 16, 2016, by Bradley Waites, Pamela Buzzetta and Crystal Bleecher.

"Designing a pyrolyzer furnace is an intricate process. There’s more to the design than making a carbon steel box, lining the walls with refractory, running some process pipes through it, and heating the pipes with burners. While this may describe the design steps in vague detail, it doesn’t capture the intricacies involved in pyrolyzer furnace design. Knowing what to consider and evaluate can be the difference between success and failure."

Many Industries Use Combined Heat and Power to Improve Energy Efficiency

Energy Collective, Jul 28, 2016.

"Combined heat and power (CHP) systems have long been used to reduce the overall energy intensity of industrial systems. There are two types of combined heat and power, depending on whether the system produces power first, then heat, or heat first, then power. In topping cycles, the hot exhaust of an electricity generator such as a natural gas turbine or reciprocating engine is used to provide process heat, hot water, or space heating for the site. According to preliminary 2015 data, topping cycles are used by 89% of total CHP capacity. In bottoming cycles, also referred to as waste heat to power, wasted heat from a furnace or other high-temperature industrial processes is recovered and used for power production."

Energy Saving Filters for Wastewater Treatment Created

Science Daily, July 7, 2016, Nanyang Technological University.

"Scientists have invented a new type of nanofilter that could reduce the energy needed to treat wastewater by up to five times. This breakthrough technology took about two years to develop and is now being commercialized across Asia."

How IIOT Monitoring Improves Pump Maintenance

Flow Control, Jul 2016, by Brett Burger.

"The Industrial Internet of Things (IIoT) will eventually connect tens of billions of “things” businesses use to operate with other machines, the cloud, control systems and people. Pumps are squarely on the list of “things,” and like many other big-iron assets that do not generate high-tech publicity, they have much to gain with this surge of technology. Why do we need IIoT pumps? What does an IIoT-enabled pump look like?"

How 3D Printing is Changing Manufacturing’s Trajectory

Flow Control, Jul 2016, by John Hornick.

"Three-dimensional (3D) printers make finished products with one process. Driven by a digital blueprint, they build layer upon layer of fused plastic, metal or other materials. 3D printing has generated a lot of hype. Some people say it is difficult to separate the hype from reality, but doing so is simple. Anything that sounds farfetched probably is not, but it will probably take longer to happen. In a world full of 3D printers, products and blueprints can be designed, customized, created and sold by innumerable companies and home printers."

Looking for a Breakthrough in Cement and Concrete

Rocky Mountain Institute, July 12, 2016, by Robert Hutchinson.

"The toughest climate challenges involve large global industries, with no good substitutes. One of these literally produces the material under our feet—concrete. Every year, each of us in the U.S. uses about one-third of a ton. Fast-growing developing countries use far more. Globally we produce over 4 billion metric tons of Portland cement per year—the key ingredient in concrete and responsible for the majority of its CO2 footprint—driving over 5 percent of total anthropomorphic CO2. RMI’s research on the topic reveals that, to have a chance of significantly shrinking the industry footprint and meeting our Paris goals, revolutionary thinking and significant disruption is needed—a Tesla for cement, as it were."
