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.

The Untapped Potential of Community Energy Storage

Microgrid Knowledge, Sept. 19, 2016.

"Robin Roy, an NRDC consultant, explains why community energy storage often falls between the gaps in federal energy policy and what can be done about the problem."

PNNL Picked to Develop Better, Cheaper Electric Car Battery

Tri-City Herald, July 25, 2016, by Annette Cary.

"A more affordable electric car might be in your future, thanks to research Pacific Northwest National Laboratory in Richland has been picked to lead. The White House announced recently that the Department of Energy lab in Richland will guide a $50 million effort over the next five years to come up with an improved electric car battery — one that is small, light and powerful."

Why Home Solar Panels No Longer Pay in Some States

New York Times, July 26, 2016, by Diane Cardwell.

"Thrust in the middle are utility regulators. Even if they support greening the grid through technology adopters like [cropped], the regulators are also responsible for ensuring that the utilities can afford to supply power to the largest number of customers at the most equitable rates. That includes people without the money or inclination to install solar collectors."

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."

Measuring the True Costs and Benefits of Energy Storage - Part 1

North American Clean Energy, Jan./Feb. 2016, by Catherine Von Burg.

"Part One: A quick guide to calculating cost & safety
A variety of new energy storage systems have emerged as business and government leaders rush to make advances in renewables and energy savings. Those systems include different chemical compositions, form factors (cylindrical cell, pouch, prismatic, flow), and battery management systems (BMS). That can make choosing a battery system challenging, even confusing. However, checking a few simple performance metrics can help calculate the true costs and benefits of competing systems. And it can help distinguish between what might look like a good price up front from what’s actually a better buy in the long run."

How Much Does Storage Really Cost? Lazard Weighs In

RMI Outlet, Jan. 21, 2016, by David Labrador.

"In November 2015, financial advisory firm Lazard released its first-ever Levelized Cost of Storage Analysis (LCOS). Well known for its Levelized Cost of Energy Analysis (LCOE) analysis—now out in version 9.0—Lazard publishing an analysis of storage is a major sign that it considers battery energy storage a critical technology that’s here to stay. But a closer look at Lazard’s LCOS shows something RMI’s October 2015 Economics of Battery Energy Storage report noted: a) battery economics are usually evaluated on the basis of single-use cases, b) stacking multiple uses can greatly enhance battery economics, and c) evaluating those economics gets difficult quickly. It’s the use cases and stacked value streams—in addition to per-kWh cell cost declines—that offer tremendous opportunity."

How Technical Advances are Driving Flow Batteries Closer to Mass Commercialization

Utility Dive, Jan. 12, 2016, by Peter Maloney.

"Recent technical advances are sparking interest in flow batteries by offering the promise of significant cost reductions that could make them better able to compete for market share with solid state storage devices, such as the nearly ubiquitous lithium-ion battery. But full commercialization is still several years off, analysts say."

Energy-Harvesting Sensors Eliminate the Need for Batteries in Some Applications

Energy Efficiency Markets, Nov. 25, 2015, by Lisa Cohn.

"Energy-harvesting sensors that are made of fabric and eliminate the need for batteries in some applications are the focus of this podcast interview with Keith McMillen, CEO and founder of BeBop Sensors."

Battery Storage Ready for Prime Time in Commercial Facilities

Building Operating Management, Sep. 2015, by Naomi Millán.

An article in 3-parts:
1) Understanding the Revolution in Energy Storage
2) Energy Storage Applications
3) Pairing Solar Power with Energy Storage

"Facility managers are no strangers to the concept of energy storage at their facilities. Most any facility of size has a UPS with a bank of lead acid batteries to carry the critical load for the few minutes it takes the generator to kick on. It has been a vital, if humdrum, system. But now there has been a revolution in the world of energy storage, and the commercial market is poised for explosive growth in the adoption of energy storage systems behind the meter. This growth is driven by a variety of factors, such as plummeting hardware costs and skyrocketing demand charges."
