Vanadium Flow Batteries for Global Academy of Technology (GAT) College
By implementing the IMERGY storage solution in the premises, GAT is able to store the energy produced by the PV panels during the day and use it during the non-solar time, thus eliminating the diesel generator run to provide clean power when needed.
Is Adding Solar Batteries Worth it?
Seeking to help states better address the value proposition of solar+storage systems, the Interstate Renewable Energy Council, Inc. (IREC) engaged Clean Power Research (CPR) to develop a methodology that could be used to value solar energy coupled with battery storage. The methodology described in the report can be applied in any location. It focuses on Hawaii as an example, as it is likely to be an early adopter of storage regulations.
"The concept of adding batteries alongside a utility customer's solar array intrigues utility customers, solar developers, and utility planners on several levels, but the underlying question for everyone is whether adding batteries is 'worth it,'" says Jason Keyes, Partner at Keyes, Fox & Wiedman LLP, attorney for IREC and report collaborator.
Though still at a nascent stage, the recent rapid growth in the distributed energy storage market suggests that now is an opportune time to take a closer look at distributed energy storage, especially in combination with distributed solar, and the values it has to offer. The new IREC study lays out the methodology to do just that and sets forth a pathway for more robust analysis and dialogue. Cont'd...

Investment In Renewable Energy Yields More Jobs Than Fossil Fuel Sector
Joshua S Hill for CleanTechnica: A new report has determined that investments in energy-efficient and renewable energy sources yield more jobs for a set amount of spending than investing in maintaining or expanding the fossil fuel industry.
[wind turbine cowboy jobs] The report, Global Green Growth: Clean Energy Industrial Investment and Expanding Job Opportunities, was published earlier this week and presented at the Vienna Energy Forum 2015 by its two authors, the Global Green Growth Institute (GGGI) and the United Nations Industrial Development Organization (UNIDO).
“Significant progress has already been made in overcoming the hitherto conventional wisdom that taking steps to cut GHGs is incompatible with economic growth,” said Yvo de Boer, Director-General of GGGI. “This report moves the debate another positive step forward by showing that employment and development result from sustainable, green growth.”
Crude Oil's Impact on Renewable Energy: Energy Alternative or Energy Staple?
With the removal of fossil fuel subsidies and the continual drop in capital costs in renewables technology, the margins for the leading players in the renewables industry will increase.
FastRack510 Installed at Hawaii's Largest Airports
The airports are not only in hurricane prone regions, but also in areas of high seismic activity. The minimal seismic anchors were installed at a rate of up to five per man hour.
24M Introduces the Semisolid Lithium-Ion Battery
Today, 24M emerged from stealth mode to introduce the semisolid lithium-ion cell, a revolutionary technology that solves the grand challenge of energy storage by enabling a new, cost-effective class of the lithium-ion battery. 24M’s semisolid lithium-ion is the most significant advancement in lithium-ion technology in more than two decades and combines an overhaul in battery cell design with a series of manufacturing innovations that, when fully implemented, will slash today’s lithium-ion costs by 50% and improve the performance of lithium-ion batteries. The technology will accelerate the global adoption of affordable energy storage.
Until now, the energy storage field has had two options to try to drive down costs – build massive and complex factories to produce lithium-ion batteries in high volumes or pursue entirely new chemistries that may never move from the lab to the commercial floor. With the invention of the semisolid lithium-ion battery, 24M presents a third option – work with the world’s preferred energy storage chemistry and unlock new opportunities for cost reductions through new cell design and manufacturing innovations. 24M’s platform is the most significant advancement in lithium-ion technology since its debut more than 20 years ago.
Maximizing the Benefits of Roof-Mounted Solar Arrays for Commercial Buildings
Contractors, builders, roofing companies, and property managers have a rare and unique opportunity to profit from the expansion of solar as it becomes more and more mainstream.
Trina Solar to Invest $500 Million in India-Based Solar Plant
Per a media report, Trina Solar Limited is going to invest $500 million for building a 2-gigawatt solar module plant in India in partnership with Welspun Energy Ltd. The plant's output will be exported to the U.S. and European markets, which have imposed punitive trade duties on solar shipments from China.
The facility will be built in either Gujarat or Andhra Pradesh. Construction of the plant will be completed in two phases over a period of about 18 months.

Nissan to incorporate used Leaf batteries in home energy storage system
Following in the footsteps of Tesla and Mercedes-Benz, Nissan is now set to become the latest automaker to offer battery packs for stationary energy storage. Although pricing information has yet to be provided, the Nissan product should be relatively affordable, as it will incorporate used batteries from Nissan Leaf electric cars.
Nissan designed the battery packs as part of the 4R Energy joint venture with Sumitomo Corp., and has partnered with commercial energy storage company Green Charge Networks to manufacture them. While Nissan is the source of the actual "second life" lithium-ion batteries that no longer meet the demands of automotive use, Green Charge is providing the power management software.
According to Nissan, this is the first time that used EV batteries have been commercially utilized for such an application. "A lithium-ion battery from a Nissan Leaf still holds a great deal of value as energy storage, even after it is removed from the vehicle, so Nissan expects to be able to reuse a majority of Leaf battery packs in non-automotive applications," says Brad Smith, director of Nissan's 4R Energy business in the US.

Is Climate Change a Reality?
Yes, history has shown that there has been global climate changes that were not brought about by human activities; but-and this is a big but-human activity is accelerating global change and not for the better.
Designer Carbons Are Getting a Boost from Nanotechnology
By Richard Martin for The MIT Technology Review: A group of Stanford researchers have come up with a nanoscale “designer carbon” material that can be adjusted to make energy storage devices, solar panels, and potentially carbon capture systems more powerful and efficient.
The designer carbon that has reached the market in recent years shares the Swiss-cheese-like structure of activated carbon, enhancing its ability to catalyze certain chemical reactions and store electrical charges; but it’s “designed” in the sense that the chemical composition of the material, and the size of the pores, can be manipulated to fit specific uses.
The designer carbon tested at Stanford is “both versatile and controllable,” according to Zhenan Bao, a professor of chemical engineering and the senior author of the study, which appeared in the latest issue of the journal ACS Central Science.
“Producing high-surface-area carbons with controlled chemical composition and morphology is really challenging,” says Bao. Other methods currently available, she says, “are either quite expensive or they don’t offer control over the chemical structure and morphology.” Cont'd...
