Nissan launches British-made home battery to rival Tesla's Powerwall. Batteries that have powered electric cars around the UK will get a second life providing energy storage for households, with the launch this week of a British-made home battery to rival the one made by Elon Musk’s Tesla.
The cells will be made by the Japanese car-maker Nissan in Sunderland, where its popular Leaf electric car is built, and sold in partnership with the US power firm Eaton. Buyers will be able to choose cheaper, used batteries that are no longer fit for electric car use, or pricier new ones. They are believed to be the first British-made household batteries pitched to the embryonic UK home storage market. What's the Difference Between a Battery and a Supercapacitor?
A supercapacitor is a high-capacity capacitor that bridges the gap between electrolytic capacitors and rechargeable batteries.
Supercapacitors accept and deliver charges much faster than a battery and are able to tolerate many more charge and discharge cycles; however, they traditionally have had a lower breakdown voltage and limited energy density when compared to a battery. Battery Chemistry A battery consists of one or more electrochemical cells. Search for the Super Battery - Documentary. Search for the Super Battery - Documentary. Cientistas criam bateria potente com garrafas de vidro usadas. (pixinoo/iStock) Se conseguimos passar duas ou três horas no notebook sem estarmos presos a tomadas, temos de agradecer às baterias de íon de lítio.
Elas estão por trás dessa autonomia que computadores e celulares possuem, e são uma forma de armazenar energia elétrica a um custo relativamente baixo. Uma descoberta feita por cientistas norte-americanos, porém, foi capaz de aumentar e muito seu rendimento. E o melhor, de uma forma sustentável – já que o material necessário para isso vem de garrafas de vidro usadas. Garrafas são feitas de areia, que por sua vez é composta essencialmente de quartzo (SiO2). Entenda “ânodo” como o pólo negativo de uma fonte de energia. Ânodos de silício são capazes de armazenar até 10 vezes mais energia que os de grafite. Para criar ânodos eficientes, e sobretudo livres de explosões, os cientistas apostaram na transformação do óxido de silício em nanosilício. How a 94-Year-Old Genius May Save the Planet. Photo Credit: Sunny studio / Shutterstock.com A man old enough to be Mark Zuckerberg’s great-grandfather just unveiled energy storage technology that might save the planet.
John Goodenough is 94, and his current work could be the key to Tesla’s future—much as, decades ago, his efforts were an important part of Sony’s era of dominance in portable gadgets. Over the years, Goodenough has scuffled with Warren Buffett, wound up screwed by global patent wars, never got rich off a headline-grabbing initial public offering and defied the American tech industry’s prejudice that says old people can’t innovate. Contrast that with the way we celebrate Evan Spiegel, who at 26 is worth $5 billion because he co-created Snapchat, an app that will probably impact humanity over the long run as profoundly as Cap’n Crunch cereal. Maybe. End of Gas-Powered Cars? Battery technology may not make you swoon, but it is the missing link in getting the planet off carbon-based energy. Lithium-Ion Battery Inventor Introduces New Technology for Fast-Charging, Noncombustible Batteries. Tesla Powerwall: What you need to know. As usual, Elon Musk was extremely convincing in his most recent announcement about Tesla's new Powerwall battery.
Imagine: in a matter of months, you could be weaned off fossil fuels and start participating in the clean energy ecosystem of the future. Your home or business could be off the grid completely. As solar energy is more widely adopted, a dedicated battery to store the energy makes a lot of sense. Top Ten Facts about Tesla’s $350/kWh (DC) PowerWall battery. Special post by Bruce Lin and Matthew Klippenstein [Edit May 11 – corrected PG&E peak price to $0.36 not $0.40/kWh – $0.36 was used in the calculation] There’s an MBA joke about scaring your clients by asking them “What’s your China strategy?”.
Today, it’s “What’s your Tesla strategy?” $350/kWh (DC) retail really is that significant. The Tesla Home Battery. Tesla Powerwall 2 has no competition – comparison with LG Resu and SonnenBatterie. As we reported when Tesla officially unveiled the Powerwall 2 last week, the new battery pack is a game changer in home energy storage.
The new price point for twice the energy capacity and the integrated inverter are hard to beat specifications for the competition, which had significantly increased since Tesla introduced first generation Powerwall over a year ago. In order to get a better idea of how disruptive the new Powerwall 2 can be, we compared it with some of the other important residential home battery pack solutions. The price points of most solutions have so far made them unavailable to most markets in the US. Like Tesla’s first generation Powerwall, other companies have concentrated their efforts on markets with higher electricity rates, like Australia and Germany. But more recently, some of the biggest players in the field felt confident enough to enter the US market, like LG with the RESU and sonnenBatterie with the Eco Compact.
The Battery Miracle Will Transform Both Transportation And Power Generation. Low-cost, high-performance electric batteries are a game changer for the two key clean energy sectors: power generation and transportation.
They enable much greater adoption and penetration of both renewable energy and electric vehicles — not just electric cars but electric buses and electric planes. Off Grid Saltwater Battery Can Power Home for 10 Years! Posted Categories: Energy The batteries allow the user to have a more steady supply of solar power and to store all energy that comes in throughout the day, none of it to go to waste.
The batteries provide power during storms and outages, and can weather almost any storm. Recycle Tires to Make Supercapacitors for Electric Cars and the Powergrid. The technology, described in a paper published in ChemSusChem by Wiley-VCH, follows an ORNL discovery of a method to use scrap tires for batteries.
Together, these approaches could provide some relief to the problems associated with the 1.5 billion tires manufacturers expect to produce annually by 2035. “Those tires will eventually need to be discarded, and our supercapacitor applications can consume several tons of this waste,” Paranthaman said. “Combined with the technology we’ve licensed to two companies to convert scrap tires into carbon powders for batteries, we estimate consuming about 50 tons per day.” While that amount represents just a fraction of the 8,000 tons that need to be recycled every day, co-author Yury Gogotsi of Drexel noted that other recycling companies could contribute to that goal.
“Each tire can produce carbon with a yield of about 50 percent with the ORNL process,” Gogotsi said. The Tesla battery heralds the beginning of the end for fossil fuels. While wind and solar power have made great strides in recent years, with renewables now accounting for 22% of electric energy generated, the issue that has held them back has been their transience.
The sun doesn’t shine at night and the wind doesn’t blow year-round – these are the mantras of all those opposed to the progress of renewables. Now the renewable power billionaire Elon Musk has just blown away that final defence. Last Thursday in California he introduced to the world his sleek new Powerwall – a wall-mounted energy storage unit that can hold 10 kilowatt hours of electric energy, and deliver it at an average of 2 kilowatts, all for US$3,500. That translates into an electricity price (taking into account installation costs and inverters) of around US$500 per kWh – less than half current costs, as estimated by Deutsche Bank. Not just for homes The Tesla Energy system launched last week is comprehensive, with global ramifications. The revolution begins Musk will not be alone. Tesla's New Battery Doesn't Work That Well With Solar.
Tesla Chief Executive Elon Musk introduced a new family of batteries designed to stretch the solar-power revolution into its next phase. There's just one problem: Tesla's new battery doesn't work well with rooftop solar—at least not yet. Even Solar City, the supplier led by Musk, isn't ready to offer Tesla's battery for daily use. The new Tesla Powerwall home batteries come in two sizes—seven and 10 kilowatt hours (kWh)—but the differences extend beyond capacity to the chemistry of the batteries. The 7kWh version is made for daily use, while its larger counterpart is only intended to be used as occasional backup when the electricity goes out.
MIT Energy Storage Discovery Could Lead to 'Unlimited' Solar Power. Clean Power Published on October 25th, 2008 | by Andrew Williams Researchers at Massachusetts Institute of Technology (MIT) have discovered a new way of storing energy from sunlight that could lead to ‘unlimited’ solar power. The process, loosely based on plant photosynthesis, uses solar energy to split water into hydrogen and oxygen gases. When needed, the gases can then be re-combined in a fuel cell, creating carbon-free electricity whether the sun is shining or not.
According to project leader Prof. Wireless Electric Car Charging Closer to Reality. Photo: Volvo 20 kW Induction System Flanders' Drive, Volvo, Van Hool, Bombardier and others are partnering to work on creating an induction charging system that could allow electric vehicles to be charge quickly and conveniently. Just park over a buried plate and log in the system (unlike in the image above, it'll probably be done by wireless identification), and voilà! Charging a battery pack of the size fitted to the Volvo C30 Electric(24 kWh), which Volvo will use for testing, is expected to take about an hour and twenty minutes, if the battery is entirely discharged. In inductive charging, a charging plate is buried in the ground--e.g., in the driveway at home where the car is parked. Graphene supercapacitors created with ‘traditional paper making’ process, rivals lead-acid battery capacity. Materials engineers at Monash University in Australia have devised a method of producing graphene supercapacitors that have the same energy density as the lead-acid battery under your car’s hood.
Not only are these supercapacitors about 10 times more energy-dense than commercial devices, but the method of producing the graphene inside the supercapacitors seems to be novel as well. The engineers say they used a process that is similar to traditional paper making — and that it could easily and cost-effectively scaled up for commercial production of graphene, and graphene-based supercaps. Supercapacitors are essentially small batteries that can recharge and discharge almost instantly. Graphene supercapacitors are 20 times as powerful, can be made with a DVD burner. A team of international researchers have created graphene supercapacitors using a LightScribe DVD burner. These capacitors are both highly flexible (pictured below) and have energy and power densities far beyond existing electrochemical capacitors, possibly within reach of conventional lithium-ion and nickel metal hydride batteries. The team, which was led by Richard Kaner of UCLA, started by smearing graphite oxide — a cheap and very easily produced material — films on blank DVDs.
Forget batteries: future devices could store power in wires. Batteries have always been one of the biggest problems when developing small lightweight electronic devices. They're big and bulky, taking up a serious chunk of the real estate inside your smartphone or tablet. So imagine if they could be dispensed with, and replaced by a new type of internal wiring that can actually store power inside the body of the wire itself. That's the goal of a team of nanotechnology researchers at the University of Central Florida in Orlando. Professor Jayan Thomas and Ph.D. student Zenan Yu have developed a way to cover copper wires with a sheath made from alloy nanowhiskers, which then become one of the two electrodes needed to create a supercapacitor.
A second tube with nanowhiskers is then added, with a thin plastic boundary layer placed between the two sheaths to complete the capacitor. Dr. University of Central Florida, via Treehugger.
