The World's Largest Storage Battery

Image
By 2021, electricity use in the west Los Angeles area may be in for a climate change-fighting evolution. For many years, the tradition has been that on midsummer afternoons, engineers will turn on what they call a “peaker,” a natural gas-burning power plant In Long Beach. It is needed to help the area’s other power plants meet the day’s peak electricity consumption. Thus, as air conditioners max out and people arriving home from work turn on their televisions and other appliances, the juice will be there. Five years from now, if current plans work out, the “peaker” will be gone, replaced by the world’s largest  storage battery , capable of holding and delivering over 100 megawatts of power an hour for four hours. The customary afternoon peak will still be there, but the battery will be able to handle it without the need for more fossil fuels. It will have spent the morning charging up with cheap solar power that might have otherwise been wasted. Early the next morning, the battery wi

Rockhampton Man Leads Solar Technology Charge

Image
Eager to cut back on his quarterly $1700 bill, the Millroy St resident is now leading the pack as the first in Rockhampton to have installed and registered the Tesla Powerwall home battery - designed by the entrepreneurs behind Tesla vehicles and privately owned satellite launch company Space-X, which works for NASA. Solahart manager and design engineer Grant Bond installed the system about one month ago, and explained the system was a "scaled down" version of the  batteries  used in Tesla's solar-powered cars, and worked with solar panels to potentially cut back your usage from the grid to zero. "In essence the solar panels produce power through the day, that power initially is going into Peter's house so any power he is using during the day he is using through the solar panels," Grant explained. "And any leftover is then going into the battery, charging the battery, and then in the afternoon and evening he is drawing power back out of the battery.&q

The Tesla And Solar City Merger

Image
Elon Musk, CEO of Tesla [NASDAQ:TSLA], plans to buy his cousin’s company, Solar City [NASDAQ:SCTY]. That has generated a lot of head-scratching in financial circles about how it will work out. Some facts commonly cited: Tesla is the most successful and biggest electric car company the world has ever seen. Solar City is America’s biggest residential solar company. Both companies lose money. Both are deeply dependent on billions of dollars in taxpayer subsidies, and both are at the epicenter of dreams to ‘green’ the highways and the grid. Strip away debate about operational synergies and the sustainability of subsidies and you find a single technological article-of-faith animating believers in the companies’ conjoined vision: the idea that fantastically better  batteries  are in the imminent future. The battery pack is by far the most expensive component in a Tesla. In a conventional car, there is no equivalent component so expensive and dominant. Fantastically better batteries are k

Residential Battery Storage Not Yet

Australian homeowners may be flocking to energy storage in droves. But one of the country’s biggest engineering consultancies doesn’t see the financial sense in it. Victoria-based Aurecon, which has operations across Africa, Asia, Australasia and the Middle East, and which has been associated with major renewable energy projects such as the Kogan Creek Solar Boost plant, says the financial impact of adding batteries to residential PV is “negative." “Aurecon has modeled multiple scenarios with a Tesla Powerwall  lithium-ion battery  coupled with a 4-kilowatt rooftop PV system,” said Victor Young, the company’s market director for energy, oil and gas. “Adding batteries increases the cost of power even in the most favorable circumstance of a zero feed-in tariff from the network provider.” As it happens, the Powerwall might not be the best battery on the Australian market, on a cost per total warranted kilowatt-hours basis. That honor currently goes to the Redflow ZCell zinc-bromide

LiFePo4 Batteries Will Enhance Energy Density

Recently, new energy vehicle power battery materials Summit held in Hefei, Huazhong University of Science and Technology [microblogging] Dean of Materials Science and Engineering, made a speech and said that Huang Yunhui, lithium iron phosphate and lithium-rich nanotechnology and application of technical and other means which will greatly enhance the practical energy density, lithium iron phosphate and implementation costs 2 yuan / watts no problem. Undoubtedly, this view if provoked uproar uniform gathered people in the industry's attention. Huang Yunhui keynote address at the forum, said, currently made of  lifePo4 batteries  is about 100Wh / kg. Now to develop reach 250,260Wh / kg the next generation, the next step it will have an energy density of more than 300Wh / kg. To achieve such high specific energy of lithium iron phosphate batteries, on the one hand to consider the issue from the material itself, on the other hand, should be considered from the technical preparation

Power Battery Safety: PACK and BMS Is Sticking Point

Benefit from the domestic policies of new energy vehicles and power  lifePo4 batteries  industry's strong support, in 2015 the new energy automobile production and sales surge, battery power shortage, dividend policy to benefit the whole industry chain. Industry insiders estimate that 2016 will usher in the first year of battery development. Battery long-term trend is no doubt, but safety is the primary criterion for consumer choice of products. Recently the Ministry of Industry "halt" Three lithium battery, a series of pure electric VW Golf 5561 due to "battery management system problems," recalls other incidents occurred, once again sparked public concern about the safety performance of the battery. For the safety of the battery, in addition to battery materials technology road dispute, the industry generally believe that the role PACK battery and BMS in safeguarding security irreplaceable. Power Battery PACK product consists of three parts, namely the ba

Solar Car Far Away From Us ?

How Solar Car Work? Solar vehicle is solar energy into electricity to drive the car.The whole car like a big  portable solar power generator . GaAs thin film solar battery technology conversion rate of 31.6%, this is the world's highest level, which also made a solar car provided technical backing. Gallium arsenide thin film solar cell technology will continue to improve the conversion rate. According to reports, in good sunlight conditions where annual solar energy can reach tens of thousands of kilometers; and in poor sunlight conditions where the amount of sun throughout the year to be driven about 20,000 kilometers. Sun a Few Hours Is Enough? Solar car appeared to be mainly rely on natural sunlight to provide energy, if a sunny day, don't worry about lack of energy. In SolarA computing models, vehicle weight of 1.2 tons and a maximum of 7.5 m2 body surface area stretched after laying; sunny day in the light for 5-6 hours, can generate approximately 8-10 degrees. No Suns
