Energy Newsbriefs Blog

The WSU Energy Program Library prepares this current awareness blog with funding from the U.S. Department of Energy State Energy Program. These articles highlight energy-related news, articles, and reports about energy efficiency, energy conservation, and renewable sources of energy for energy professionals and interested members of the public.

Digester Mixing Fundamentals

BioCycle, Feb. 2017, by Craig Coker and Gene Smith.
https://www.biocycle.net/2017/02/14/digester-mixing-fundamentals-2/

"Anaerobic digestion (AD) is a biological manufacturing process where waste materials such as food wastes, animal manures and sewage sludges are converted, in the absence of oxygen, to products such as biogas and digestate. AD is traditionally a liquid process; that is, it often occurs in sealed reactors processing a thin liquid with a 93 to 99 percent moisture content.... Mixing maintains integrity of the decomposition process by improving circulation and consistency, and minimizing volumes of the scum and grit layers."

Biomass Test Delayed at Boardman Coal Plant

East Oregonian, Dec. 30, 2016, by George Plaven.

"Portland General Electric had planned to conduct a full-day test burn at the plant using nothing but woody debris by the end of December. However, as winter weather had Oregonians cranking up the heat, PGE needed all resources on deck to keep up with the surge in electricity demand."

Bioenergy Byproduct to Soil Savior [Biochar]

Biomass Magazine, Nov. 2016, by Anna Simet.

"Production and sale of biochar at biomass-using plants can result in significant financial gains, but the industry is still working at building its myriad of potential markets."

Fuel Of The Future? [Biomass]

Northwest Power and Conservation Council, Oct. 18, 2016, by John Harrison.

"Portland General Electric will stop burning coal at its Boardman power plant in 2020, replacing coal with biomass including a bamboo-like cane."

Passing the Test: Biomass Systems on College Campuses

Biomass Magazine, Oct. 2016, by Katie Fletcher.

"As college and university fossil fuel heating plants age and become inefficient, many are evaluating, building or have already installed biomass systems."

Researchers Make Breakthrough In Biobased Materials

Washington State University News, Sept. 28, 2016, by Tina Hilding.
https://news.wsu.edu/2016/09/28/researchers-make-breakthrough-biobased-materials/

"Washington State University researchers have developed a way to practically separate lignin from wood, a breakthrough that could provide new sources of lignin for advanced renewable fuel and advanced materials applications."

California Biomass: Abundant Fuel Needs Policy Solution

Biomass Magazine, Aug. 2016, by Bob Cleaves.
http://biomassmagazine.com/articles/13488/california-biomass-abundant-fuel-needs-policy-solution

"California continues to be a frustrating illustration of the paradox of biomass nationwide: So much fuel exists and needs a place to go, yet many biomass facilities are struggling to stay open. An estimated 66 million dead and diseased trees across California—enhanced by a years-long drought combined with a pine beetle epidemic—means fuels are plentiful, but they aren’t being used for biomass power."

The Intricacies of Pyrolyzer Furnace Design

Biomass Magazine, August 16, 2016, by Bradley Waites, Pamela Buzzetta and Crystal Bleecher.
http://biomassmagazine.com/articles/13482/the-intricacies-of-pyrolyzer-furnace-design

"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."

The Future of Bioenergy Is in this Book-less Library

U.S. Department of Energy, May 3, 2016. by Cory Hatch.
http://www.energy.gov/articles/future-bioenergy-book-less-library

"The Bioenergy Feedstock Library contains no books. What it does contain is information about biomass -- organic material such as corn stover, switchgrass, wood chips and wheat straw. Nearly 50,000 biomass database entries and more than 35,000 physical samples reside in a repository located at the Department of Energy’s Biomass Feedstock National User Facility."

Staving Off a Sunset [Biomass in California]

Biomass Magazine, Apr. 2016, by Bruce Dorminey.
http://biomassmagazine.com/articles/13059/staving-off-a-sunset

"While California’s biomass power industry continues its struggle for survival, fuel suppliers are left without a home for mounting materials."
