Tesla’s Powerwall Is the Latest Step Toward Our Clean-Energy Future

They find it hard to believe that solar energy is fewer than 14 years away from meeting 100 percent of today’s energy needs. They argue that today solar energy hardly provides one percent of Earth’s energy needs and that we can’t effectively store sunlight — and therefore have a long way to go. But when technologies advance exponentially as solar is doing, one percent solar means we are halfway from 0.01 percent to the goal of 100 percent. The prices of solar panels have fallen 75 percent in the past five years and are advancing on a scale comparable to Moore’s Law, as tech guru Ramez Naam has documented. What has been holding solar back so far has ostensibly been the cost of storage. The Powerwall is available in two configurations: 7kWh and 10kWh. Tesla gearing up for release of batteries for the home.

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts.

Tesla gearing up for release of batteries for the home

The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle. Official details of the project are still a ways off. When we contacted them, Tesla said they’re currently not sharing any additional information about their energy storage and home batteries for several months. What Musk did reveal during the conference call was that "we’re going to unveil the Tesla home battery, or consumer battery, that will be for use in people’s houses or businesses, fairly soon. " Adding that, "we have the design done and it should start going into production probably in about six months or so. One area where Tesla might stand out is in cost.

Battery Performance Is Hurting Hawaii’s Solar Push. The prospect of cheaper, petroleum-free power has lured the Kauai Island Utility Cooperative (KIUC) to quintuple utility-scale solar capacity over the past year, building two 12-megawatt photovoltaic arrays.

Battery Performance Is Hurting Hawaii’s Solar Push

These facilities are the biggest and a significant contributor to the island’s 78-megawatt peak power supply. When the second plant comes online this summer, peak solar output on Kauai will approach 80 percent of power generation on some days, according to Brad Rockwell, the utility’s power supply manager. That puts Kauai on the leading edge of solar power penetration, and KIUC has bruises to show for it. Power fluctuations from a first large plant installed in 2012 have already largely burned out the big batteries installed to keep solar from destabilizing the island’s grid. Now KIUC is taking a second try with batteries and hoping energy storage technology has progressed sufficiently to keep the same problems from recurring. The solar plant in Anahola is nearing completion. Brain scan: Tesla’s electric man. PUT your foot down in a Tesla Model S and the experience is rather different to other cars.

Brain scan: Tesla’s electric man

The usual exhaust roar is replaced by a hushed whooshing sound as the car accelerates rapidly—and relentlessly—thanks to the high torque of an electric motor making gear changes unnecessary because there is no gearbox. And inside, instead of multiple dials and switches, a large touchscreen dominates the centre console. Established carmakers have tended to make modest electric vehicles, usually small ones to eke out the range available from their pricey batteries. But it was Tesla, a Silicon Valley startup, which realised that many early adopters of new technologies are likely to be well heeled and would prefer a large high-performance saloon that is both luxurious and extremely high-tech.

Why did Tesla act differently? Mr Straubel’s captivation with energy storage is understandable. The best way to do that and to meet expected demand, Mr Straubel believes, is for Tesla to make its own batteries. No Outlet, No Problem: This New Technology Could Power Your Gadgets Wirelessly. New Li-ion anode achieves 70 percent charge in just two minutes. Researchers at the Nanyang Technological University (NTU) in Singapore have developed a new, proof-of-concept anode for lithium-ion batteries that can charge to 70 percent of its capacity in only two minutes and has a very long lifespan of ten thousand charge/discharge cycles.

The advance could lead to the production of high-rate lithium-ion batteries, with interesting implications for personal electronics and, perhaps, even electric vehicles. View all Lithium-ion batteries owe their popularity to their ability to store large amounts of energy into a relatively small and light package; however, they can take a fairly long time to charge. New "dual carbon" battery charges 20 times faster than Li-ion. Japanese company Power Japan Plus has announced the development and planned mass-production of "Ryden," a disruptive carbon battery that can be charged 20 times faster than an ordinary lithium-ion cell.

The battery, which is cheap to manufacture, safe, and environmentally friendly, could be ideal to improve the range and charging times of electric cars. View all We've seen electric cars and motorbikes make huge strides forward in recent years. Up to a few years ago, electric vehicles were a synonym of peculiar designs, poor performance, and very low range; but now, more and more people associate them with instant torque and high performance. Further improving range, charging time, and cost would make electric vehicles an even more compelling product. PowerjapanPlus. Power Japan Plus Reveals New Ryden Dual Carbon Battery New battery design balances the need for cost competitive energy storage that is energy dense, reliable, safe and sustainable SAN FRANCISCO, Calif. — May 13, 2014 — Power Japan Plus today launched a new battery technology – the Ryden dual carbon battery.

Nanodot-based smartphone battery that recharges in 30 seconds. Cheap batteries will revolutionise the renewable energy market. News this week, from opposite ends of the planet, that points to the convulsion of change about to hit the global economy. The first report came from Palo Alto, California, headquarters of the Tesla electric car company. Battery Advance Could Help Solve Renewable Energy Intermittency. Utilities would love to be able to store the power that wind farms generate at night—when no one wants it—and use it when demand is high during the day.

Battery Advance Could Help Solve Renewable Energy Intermittency

But conventional battery technology is so expensive that it only makes economic sense to store a few minutes of electricity, enough to smooth out a few fluctuations from gusts of wind. Harvard University researchers say they’ve developed a new type of battery that could make it economical to store a couple of days of electricity from wind farms and other sources of power. The new battery, which is described in the journal Nature, is based on an organic molecule—called a quinone—that’s found in plants such as rhubarb and can be cheaply synthesized from crude oil. Holistic cell design leads to high-performance, long cycle-life lithium-sulfur battery. Researchers at the U.S.

Holistic cell design leads to high-performance, long cycle-life lithium-sulfur battery

Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery's capacity. This is longest cycle life reported so far for any lithium-sulfur battery. To understand the potential of Tesla, look to the forest, not the trees. The bulk of the attention on Tesla recently has been squarely centered on the trees: Tesla’s quarterly earnings, its stock dive and weekly volatility, the three accidents that have led to fires.

But don’t forget the forest: Tesla’s Model S has been a big success, and it’s part of a long term evolution that will allow Tesla to eventually deliver its third-generation, mainstream electric car. Finding success with that monumental project will be even more difficult than it was with the Model S, yet it will be even more of a revolutionary step toward moving the world off of gasoline-powered cars. Think about it this way — the success of the Model S is like when the San Francisco Giants came back from a losing streak and won three division series games in a row to beat the Reds in the 2012. It was jaw-dropping, exciting and the Giants survived that all-odds-against-them series and got to go onto the World Series. The first 3D-printed battery is as tiny as a grain of sand. Imagine a computer so small it could slip through the human bloodstream. At just a millimeter in width, a new battery built by a Harvard University and University of Illinois team is perfectly suited to be a power source for tiny computers.

It is also the first battery to ever be fabricated with a 3D printer. The team used a custom printer and ink to produce the batteries. A nozzle .03 millimeters–or 30 microns–wide deposited layers of nanoparticle-packed paste in a comb-like shape. A second printed comb nestled into the first, their teeth interlocked. After printing, the electrode layers quickly hardened and were placed in a small container filled with solution. A battery like this could transform fields like robotics, which are limited by how small they can build product by currently available materials.

Co-author Jennifer Lewis mentioned Harvard’s Robobees–tiny autonomous drones–as a potential application. “Why not print the whole hearing aid?” USU Researchers Trial Wireless Charging of Electric Bus. Charging system is quite forgiving of air gap, misalignment with charging pad Utah State University's Wireless Power Transfer team has applied "a mix of modern advances in engineering and Nikola Tesla's principles of induction" to create a unique mass transport electric vehicle, the Aggie Bus.

While the Aggie Bus at first blush is just a battery-electric conversion of a standard passenger bus, it has a pretty unique trick. Professor Hunter Wu's team of faculty and student researchers, along with engineers at the Utah Science Technology and Research (USTAR) initiative's Advanced Transportation Institute at USU, created wireless power transfer (WPT) pads that charge the bus as it reaches stops. We solve the battery problem. Texas mega-battery aims to green up the grid - tech - 01 February 2013. IN A remote corner of west Texas, in the shadow of a sprawling wind farm, one of the world's largest batteries was switched on last week.

Deep in oil country, the battery is at the vanguard of efforts to help renewable energy sources realise their potential and, ultimately, oust fossil fuels in the US.
