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.

U.S. Microgrid Market Development

Power Magazine, May 2016, by Gail Reitenbach.
http://www.powermag.com/u-s-microgrid-market-development/

"Microgrids have been around for decades, but today, more potential customers, owners, technologies, and vendors than ever are part of the market. Increased interest in this special grid resource means there’s more competition, which is generally a good thing, but there are also new challenges."

New Cogen System Triples Energy Output from Biogas at Oregon WWTP

Biomass Magazine, May 2015, by Katie Fletcher.

"On May 4, Clean Water Services, Energy Trust of Oregon and the Oregon Department of Energy formally announced the implementation of a new cogeneration system that converts wastewater and grease into renewable energy. The innovative system, which is part of Clean Water Services Durham Treatment Facility, is the third cogeneration system in Oregon to codigest fats, oils and grease (FOG)."

Measuring the True Costs and Benefits of Energy Storage, Part 2

North American Clean Energy, Mar/Apr 2016, by Katherine Von Burg.

"Part Two - How cycle life and environmental factors impact LCOE
In last month’s issue, Part One of this series began covering how checking a few simple performance metrics can help calculate the true costs and benefits of competing energy storage systems. Additionally calculating this levelized cost of energy (LCOE) can help distinguish between what might look like a good price up front from what’s actually a better buy in the long run."

Hydrogen and a New Paradigm for Electricity Storage

North American Clean Energy, Mar/Apr 2016, by Ken Brown.

"A new paradigm is needed for electricity storage in the wind energy market. Today, what passes for “grid storage” are technologies providing, at most, eight to 12 hours of discharge time. If electricity generation is to be successfully weaned from fossil fuels, storage must have more than 1,000 hours of discharge time to back up renewables when they are intermittent. Sometimes the wind does not blow and the sun does not shine for long periods of time. Long discharge time provides reliability."

Onsite Power: What's It Mean to Get to Zero

Net Zero Buildings, Mar. 2016, by Chuck Ross. -- Jump to page 24.

"Net zero building has been a topic of conversation between architects and engineers for more than a decade, but there remains a significant lack of consensus over what 'net zero' actually means when it comes to the relationship between onsite energy consumption and generation."

Wind Plant Modeling Data Essential to Interconnections

North American Clean Energy, Mar/Apr 2016, by Jim Smith.
http://www.nacleanenergy.com/articles/22730/wind-plant-modeling-data-essential-to-interconnections

"Wind power developers often are not aware until the last minute before submitting an interconnection application that they are required to provide computer modeling data. Ignorance, in this case, certainly isn’t bliss, but a little awareness can make the process a lot less painful."

A Retrospective Analysis of the Benefits and Impacts of U.S. Renewable Portfolio Standards

Lawrence Berkeley Laboratory, Jan. 2016.
https://emp.lbl.gov/publications/retrospective-analysis-benefits-and

"This is the second in a series of reports exploring the costs, benefits, and other impacts of state renewable portfolio standards (RPS). This report focuses on the benefits and impacts of all state RPS programs, in aggregate, for the year 2013. Relying on a well-vetted set of methods, this report evaluates a number of important benefits and impacts in both physical and monetary terms, where possible, and characterizes key uncertainties."

Absorption Chillers For Institutional Occupancies

Engineered Systems, Feb. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/97567-absorption-chillers-for-institutional-occpancies

"It's not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success."

5 Reasons Community-Scale Solar is a Multi-GW Market Opportunity

Rocky Mountain Institute Outlet, Mar. 17, 2016, by Kevin Brehm and Joseph Goodman.
http://blog.rmi.org/blog_2016_03_17_5_reasons_community_scale_solar_is_a_multi_gw_market_opportunity

"The U.S. solar industry has enjoyed impressive growth of late, with strong forecasts for 2016, but it’s been an at-times bumpy ride as the industry has faced unfavorable rulings and stock-market troubles. Besides buckling their seatbelts, what can industry stakeholders do in this still-volatile market?.... Community-scale solar is that opportunity, and RMI shows how and why community-scale is a large and emerging opportunity in its insight brief Community-Scale Solar: Why Developers and Buyers Should Focus on This High-Potential Market Segment."

Zero Net Energy Buildings and the Grid

New Buildings Institute, Feb. 22, 2016, by Alexi Miller.
http://newbuildings.org/zero-net-energy-buildings-and-the-grid/

"As zero net energy (ZNE) and other low-energy buildings become increasingly common, we have to think about how different ZNE strategies can interact with their local electricity grids. The electricity grid was built as a one-way street, with energy flowing from the power plant to the consumer. Widely distributed renewable energy systems and other cutting-edge building technologies will change that equation."
