Flat Rates & Permitting Issues Undermine Residential Solar-Plus-Storage Market

Microgrid Knowledge, Mar. 31, 2017, by Lisa Cohn.

"Flat utility rates, permitting issues, and ambiguous or nonexistent incentives are undermining the residential solar-plus-storage market, according to a new analysis. The report by the National Renewable Energy Laboratory, the Rocky Mountain Institute, and the US Department of Energy also analyzes the prices of solar PV-plus-storage and describes hard-to-quantify benefits. It concludes that “gaps remain” in understanding and communicating costs and value. 'Installed Cost Benchmarks and Deployment Barriers for Residential Solar Photovoltaics with Energy Storage: Q1 2016' names permitting challenges as one of the major obstacles to increased deployment of solar-plus-storage."

Lithium-Sulfur: The Next Energy Storage Superstar?

"Lithium-ion batteries power many modern devices from cell phones, to cars, laptops, and a multitude of portable electronics.  But their power density is less than ideal. And there appears to be another, perhaps more promising energy storage option on the horizon: lithium-sulfur batteries."

Solar Experiment Lets Neighbors Trade Energy Among Themselves

"In a promising experiment in an affluent swath of [Brooklyn], dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door."

5 Things To Look For In Your Next Battery

North American Clean Energy, Mar. 2017.

"With hundreds of battery types and styles to choose from, how do you sift through spec sheets and marketing to find the right battery for you? Battery technology is key. Many batteries -- commercial, automotive, and UPS -- can’t handle constant cycling in renewable energy systems. Lithium-ion batteries are maintenance-free but have the highest cost per ampere-hour (Ah). They also pose fire and thermal runaway risks and cannot be fully recycled. In most, but not all, cases, lead-acid batteries are the best fit. They have the highest ROI, over 100 years of safe use, and are the most recyclable product in North America."

SnoPUD Launches New Model of Battery Architecture

"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."

"We are on the cusp of a new generation of energy, both on the residential and large-scale utility fronts. With advanced digital technology and materials such as a new generation of lithium ion batteries, the future for storage battery technology gets brighter every day."

Battery-Based Energy Storage: The Renewable Power Proliferation Enabler

"David Blood takes a look at the energy storage systems market and explores why they are so integral to renewable energy generation. Energy storage systems (ESS) are growing in importance as renewable energy sources like wind power, wave power and solar are being commissioned and connected to the grid at an ever-increasing rate. Energy Storage Systems are needed to help the grid deal with the instability and unpredictability of such power generation systems and match them to equally variable consumer demand."

Advanced Storage Battery Technology – Providing a Foundation For the New Energy Paradigm

North American Clean Energy, Nov/Dec 2016, by Jim Petersen.
http://www.nacleanenergy.com/articles/24810/advanced-storage-battery-technology-providing-a-foundation-for-the-new-energy-paradigm

"The burgeoning energy storage market is being driven by improved energy efficiency, the declining cost of solar equipment, and higher capacity energy storage made possible by improved battery technology, such as lithium ion. This creates a huge benefit to consumers of electric power, especially with federal incentives covering up to 30 percent of the total system cost."
