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.

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.

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.
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...
Joe Romm for ThinkProgress: Solar photovoltaic (PV) systems have seen explosive growth because of their stunning 99 percent price drop in the past quarter century. As a result, the other form of solar power — concentrating solar thermal power (CSP) — is a small fraction of the solar market. But the International Energy Agency (IEA) says CSP has a very bright future too because it enables cheap, efficient storage, which allows CSP plants to provide electricity long after the sun has set. According to the IEA’s 2014 CSP Technology Roadmap, 11 percent of global electricity will be generated by concentrating solar thermal power in 2050. Cont'd...
The Sustainable Cities Index from ARCADIS shows that among the top ten cities in the list, most are from Europe, while there are a few cities which are from Asia. Strangely, not a single city from North America makes it to the top-ten list.
A greater use of wood for home heating and steadily growing installation of solar systems are the main contributors to increasing renewable energy consumption in residential buildings and, to a lesser extent, in commercial buildings.
A new study has mapped out a potential plan for the United States to completely transition to clean, renewable energy by 2050. According to the research study leader Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, the process would demand significant upfront costs, but over time would be roughly equal to the costs of maintaining the fossil fuel infrastructure currently in place. “When you account for the health and climate costs – as well as the rising price of fossil fuels – wind, water and solar are half the cost of conventional systems,” Jacobson said. “A conversion of this scale would also create jobs, stabilize fuel prices, reduce pollution-related health problems and eliminate emissions from the United States. There is very little downside to a conversion, at least based on this science.” Among the positives of switching to clean energy: reducing air pollution in the U.S. that is responsible for approximately 63,000 Americans each year, and eliminating greenhouse gases produced by fossil fuel that would cost the world approximately $3.3 trillion per year by 2050, per a phys.org report.
Data analytics help fleet owners and operators reduce costs while improving system performance, thus accelerating the adoption of solar since it can better compete with other generation sources.
Stephen Edelstein for Motor Authority: Tesla Motors may be the first automaker to try selling standalone battery packs for powering homes and businesses, but it may not be the only one for long. Mercedes-Benz could soon enter the energy storage business as well. A division of parent company Daimler has been testing battery packs that can power houses or store excess electricity from the grid, and plans to launch commercially in September, according to Australia's Motoring. Called ACCUmotive, this division was created in 2009 to develop lithium-ion batteries. Like Tesla before its recent announcement, the Daimler arm has been testing energy storage systems under the radar for some time. It recently built an energy storage array operated by German electricity joint venture Coulomb. The array consists of 96 lithium-ion modules that together boast a combined 500 kilowatt hours of storage capacity, which is used to stabilize the Saxony Kamenz power grid. There are plans to expand it to 3,000 kWh of capacity. ACCUmotive has reportedly delivered more than 60,000 lithium-ion cells to customers—which may include Mercedes itself—and employs more than 250 people.
TRISTAN EDIS writes: Reposit Power are one of the first companies in Australia that have teamed up with Tesla in the roll-out of their Powerwall home energy storage system. The interesting thing about Reposit is that its primary businesses isn’t selling energy hardware but, rather, using software to aggregate and trade lots of little sources of power generation into the electricity market. Most battery retailers and installers in Australia have their roots in the off-grid market – they have sold batteries to customers because their only other option was expensive, maintenance-intensive diesel generators. But Reposit is inherently bound to the grid where there are lots of generators connected which they trade against. It means Reposit, in trying to get batteries rolled out (which they can then use to trade into the power market), face a far more challenging sales proposition. Grid-connected customers don’t really need the battery system – it’s an optional extra because the grid works extremely well in providing reliable and affordable power. Yet participants in the solar PV market know there is some considerable latent demand for batteries among householders – particularly those with solar systems – provided the offering is right. The challenge is working out what the successful marketing formula needs to be to tap this latent demand. Dean Spaccavento, chief product officer with Reposit, explained what they’ve found out so far, outlining 10 lessons of which I’ve plucked out five. The overall message is it is extremely hard to sell a grid-connected household an energy storage system. And Reposit had the benefit of an ARENA grant which allowed them to discount the price of their $25,000, 14kWh battery system by a very hefty $10,000. This was a one-off, small volume offer. To sell battery systems in Australia it will need to happen without the benefit of such a big rebate. The five lessons below provide one overarching lesson – batteries won’t be sold on some kind of pure sophisticated financial calculus of rate of return or NPV. Instead, it will be a mixture of rule-of-thumb financial hurdles and a strong dose of emotion. Cont'd....
Drones will eventually be "as ubiquitous as pigeons", London-based futurist Liam Young recently predicted. They will be used for a lot of different tasks. One overlooked drone application even has the potential to become a trillion dollar business. And to save the world.
Dominic Bates for The Guardian: A new bladeless wind turbine that promises to be more efficient, less visually intrusive, and safer for birdlife than conventional turbines has been welcomed by two of the UK wind energy industry’s most vocal critics. The RSPB and the Campaign to Protect Rural England (CPRE), which have both expressed concerns over the impacts of industrial-scale windfarms on the landscape and wildlife, said the new turbine was encouraging news for birds and had the potential to open up more urban environments to the sector. The streamlined design contains no contacting moving parts, making it virtually noiseless and less prone to vibration. Vortex Bladeless, the turbine’s Spanish developers, hopes these advantages could finally help usher in a viable consumer wind power market. “Wind turbines now are too noisy for people’s backyard,” says David Suriol, who co-founded the company with Raul Martin and the turbine’s inventor, David Yáñez. “We want to bring wind power generation to people’s houses like solar power.”
Software plays a critical role in the performance of grid-scale energy storage systems because these energy storage systems are complex to design, deploy and operate.
