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.


What You Need to Know About Renewable Diesel

Government Fleet, Mar. 2017, by Shelley Ernst.
http://www.government-fleet.com/channel/biofuels/article/story/2016/03/what-you-need-to-know-about-renewable-diesel.aspx

"What is renewable diesel? The short answer is it’s a fuel that is chemically similar to petroleum diesel, but is 100% renewable and sustainable. In other words, it’s the latest, greenest diesel on the market. But to really understand it, it’s helpful to back up and understand the difference between it and its predecessors, petroleum diesel and biodiesel."

Energy Savings Can Be Fun, But No Need To Turn Off All The Lights

"A new company is doing more than just monitoring electricity use. It's making tracking your electrical data fun. Steve Reed of San Diego says he signed up for free with OhmConnect. He was eager to see how much his family could cut back on electricity at times when there is a high demand for it in the area. Soon, he got a text prompting him to lower use for an hour — from 5 p.m. to 6 p.m. the next day. The service includes an interactive map of where your electricity is coming from. Curtis Tongue, one of OhmConnect's co-founders, says it makes climate change and pollution less remote and gives people a way to do something purposeful."

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."

SnoPUD Launches New Model of Battery Architecture

NWPPA Bulletin, Feb. 2017, by Neil Neroutsos. -- scroll to page 26 of the .pdf.

"Later this winter, Snohomish County Public Utility District will bring online its second energy storage system at a substation in Everett, Wash. The battery storage systems aim to transform the marketplace and how utilities manage grid operations. They also are designed to improve reliability and the integration of renewable energy sources, which are rapidly growing in the Pacific Northwest. The projects were made possible in part by a $7.3 million investment from the Washington State Clean Energy Fund."

What the Wall Street Journal Got Wrong About PACE

ACEEE Blog, Mar 2, 2017, by Jim Barrett.

"The growth of the PACE [Property Assessed Clean Energy] market has been so remarkable that it’s getting attention outside of the efficiency world as well as inside it. The Wall Street Journal recently published an article calling PACE the “fastest growing loan category.” But in the same article, it ominously compared PACE to the subprime mortgage crisis. If true, this would certainly merit even more attention, this time from regulators and possibly even law enforcement. Fortunately, it’s not."

Best Practices for CHP Development

Power Engineering, Feb. 2017, by Thomas G. Adams.
http://www.power-eng.com/articles/print/volume-121/issue-2/features/best-practices-for-chp-development.html

"Combined heat and power (CHP) projects promise many benefits to a wide array of large energy users, and CHP has a long history of adoption and success in many industries. Despite its wide adoption, many energy users considering the development and installation of a CHP project face a set of tasks and challenges that they are not always fully equipped to handle since their primary business is usually quite different from power and thermal energy production. By focusing on best practices from the start of project development, to execution, and on to long term operation and maintenance, new owners of CHP systems can mitigate risks and maximize the chances of success for their project."

Compressed Air System Commissioning Part 1: Why Do It?

Compressed Air Best Practices, Feb. 2017, by Tim Dugan.
http://www.airbestpractices.com/system-assessments/compressor-controls/compressed-air-system-commissioning-part-1-why-do-it

"“Retro-Commissioning” (ReCX) of compressed air systems has become a trendy activity with many utility demand-side-management programs emerging in the last 5-10 years.  This is intended to be the process of “tuning up” a compressed air system, getting low cost savings from mostly adjustments and repairs.  The term was borrowed from the building/HVAC industry, where it means to get a system operating as it was originally “commissioned”."

Steam Turbine Retrofits: Methods to Extend Turbine Life and Improve Performance

Power Engineering, Feb. 2017, by Muhammad Saqib Riaz. http://www.power-eng.com/articles/print/volume-121/issue-2/features/steam-turbine-retrofits.html "A steam turbine is designed and optimized for a specific set of steam conditions. After long term operations either the steam path components deteriorate or due to changes in steam conditions, a re-optimization of the steam path components is required to regain higher turbine performance. Steam Turbine retrofits are performed to achieve various goals such as improved turbine efficiencies, heat rate or power output. Retrofits are also performed to address turbine reliability and or maintenance issues. Availability of newer technologies and materials for steam path components can be utilized to not only increase steam turbine performance, but also to extend maintenance intervals, and extend life. Retrofits can also accommodate required changes to the thermal cycle based on emerging needs of the power plant. The effectiveness of the retrofit is achieved by ut ... Read the rest of entry »

Preliminary Energy Savings Announced for ASHRAE/IES 2016 Energy Standard [90.1]
