Virtual Power Plants Get Around Solar Power's Intermittency Problem

Richard Martin for MIT Technology Review:  Attempting to harness the power of distributed rooftop solar installations to make its grid more flexible and reliable, New York utility Consolidated Edison is launching a pilot program this summer to link dozens of small solar arrays into a single, software-connected power plant. The utility is working with solar power developer SunPower and energy storage company Sunverge to create a “virtual power plant”—a network of distributed assets that functions as a unified resource on the grid. The project will include 300 homes with a combined total of 1.8 megawatts of solar capacity and batteries that can store up to four megawatt-hours of electricity, enough to run 300 average U.S. households for about 10 hours.   Cont'd...

WattJoule Develops Cost Breakthrough for Liquid Energy Storage

WattJoule Corporation, a developer of next-generation liquid electrical energy storage systems, has developed and built a new system demonstrating a major industry cost breakthrough. The new storage platform is called ElectriStor™ and will be offered to system integrators as the preferred core component for storing large amounts of solar and wind energy.  One of the major barriers preventing the widespread adoption of large-scale energy storage has been cost. WattJoule has engineered the ElectriStor™ platform based on the redox flow battery concept where electricity is stored in a liquid. WattJoule's proprietary liquid electrolyte is mostly water, and the company has developed a new, inexpensive process to make it in large quantities. Early liquid energy storage systems have suffered from a number of technical and cost limitations. Recently there have been several technical breakthroughs to overcome these constraints. WattJoule has both developed and exclusively licensed key technologies that, in combination, dramatically lower energy storage costs to $150 per kilowatt-hour in its first-generation energy storage product.   Full Press Release:    

Two-thirds of US solar installers do not offer storage, study finds

Ian Clover for PV Magazine:  A study by EuPD Research shows just 34% of PV installers in the U.S. offer storage solutions to customers, with those reluctant to do so citing cost concerns. However, 26% that currently do not offer storage hope to include it in their portfolios this year. For all the glitzy product launches by the likes of Tesla and Sonnen, the solar+storage landscape of the U.S. is still largely shaped by what leading installers are – or aren’t – prepared to offer to customers, and a recent survey has found that around two-thirds do not currently include storage technology in their product portfolio. EuPD Research’s latest PV Installer Survey USA 2015/16 revealed that only one-third of installers already offer energy storage to homeowners or businesses in the U.S. looking to adopt solar power. Of the two-thirds that do not, 38% said that current pricing of batteries impedes demand, meaning margins are too low for installers and the "technological maturity" of the systems on the market is not currently convincing. However, the mood does appear to be shifting in favor of storage, with 26% of survey participants saying they hope to add storage products to their portfolio at some stage in 2016.   Cont'd...

These Lego-Like Batteries Plug In To Store Solar Power At Home

Adele Peters for Co-Exist:  Less than a year after Tesla unveiled its Powerwall battery for storing electricity at home, a startup has designed a much cheaper alternative that you can plug in yourself, without an electrician. The modular batteries, called Orison, can be hung on the wall or set on the ground to double as an LED lamp. If you want more power, you just add the units together. "Think of Orison like Legos," says co-founder and CEO Eric Clifton. "The 2.2 kilowatt-hour unit is really just one piece, so you can actually add as many as you need." The 2.2 kilowatt-hour version is as large as the company could make one unit and keep it under 40 pounds, so it could be easily shipped and moved. With one unit, if your power went out in a storm, you could keep an energy-efficient refrigerator running for about two days. If you want to back up everything in your house, you'd connect a long series of batteries together. For someone with solar panels on the roof, the batteries can store power to use at night. Right now, most people can sell extra solar power back to the grid when they're not using it, but many state laws are about to change so people will make less money. Batteries can help solar homeowners save money by making use of the power they've generated.   Cont'd...

Apple leftovers key for future energy storage

By Tereza Pultarova for E&T:  German researchers have developed a new carbon-based active material that can be manufactured from apple leftovers and used to build better energy storage systems. The apple-based material can be used as the negative electrode in sodium-ion batteries, which are currently being researched as a more environmentally friendly and cheaper alternative to lithium-ion batteries. Instead of energy-intensive lithium mining, which frequently damages the environment, battery manufacturers in future could be using organic waste to make batteries. In tests, the new material discovered by researchers from the Helmholtz Institute Ulm of Karlsruhe Institute of Technology, has demonstrated ‘excellent electrochemical properties’, allowing the researchers to carry out 1000 charge and discharge cycles during which the apple-based battery demonstrated high stability as well as capacity.   Cont'd...

Orison Plug-And-Play Energy Storage System Live On Kickstarter

Orison, an energy storage company, announced today that the first true plug-and-play energy storage system is now available for pre-order on Kickstarter. Orison powers homes and businesses to reduce energy costs, provide backup energy during blackouts, and contribute to a clean energy future. The Orison Kickstarter Campaign can be found at: http://kck.st/1Kr9Zn5   Orison envisions a future with abundant, clean, and affordable energy for all. The networked, distributed energy storage solution gives consumers control so they can store energy from any electricity source, including grid or solar power, to access energy whenever it's needed. When powered by the grid, it stores energy when utility rates are low to power homes and businesses when rates are high. If connected to solar, Orison allows consumers to locally store the energy they produce so that it will not be sold at a loss to the utility. By localizing energy distribution, Orison helps to save money and reduce peak demand.   Full Press Release:
