Solid-State Batteries For Grid

Image
The solid-state batteries that are on the market today are thin-film batteries, which, on account of their limited capacity, can only be used for micro-storage, for example to provide power for sensors. But as a result of innovations in materials and architecture, solid-state  batteries  may soon be used also for large storage systems, for example for electric cars or the smart grid.  The development of solid-state electrolytes with high Li-ion conductivity is an important link in achieving that aim. At imec, a nano-composite electrolyte has been developed which can bring solid-state batteries one step closer to the market. This article comes from http://www.storagebattery-factory.com/news/Solid-State-Batteries-For-Grid.html.

Around The World With Zero Fuel

The first aircraft powered solely by the sun made a historic landing in Abu Dhabi on Tuesday, completing the 25,000 mile, round-the-world journey that began in March 2015. The Swiss-engineered Solar Impulse 2 was piloted by Bertrand Piccard on the final part of its epic expedition that took off from Cairo earlier this week. The last stop completes its 17-leg, milestone journey using only the power of the sun's rays. The lightweight aircraft, which weighs the same as an SUV but has the wingspan of a Boeing 747, is the brainchild of Piccard and Bertrand Borschberg, a Swiss engineer and businessman. The aircraft is a single-seater, so the two men have shared the flying by taking different legs of the journey. "What I'd like to show with my team is that clean technology today is showing incredible goals. You can fly now longer without fuel than with fuel, and you fly with the force of nature, you fly with the sun. It's the new era now for energy and this is really what

Solar Batteries Performance Enhancing Vitamins

Harvard University researchers reckon they can make flow batteries cheaper using an electrolyte based on vitamin B2. Flow batteries function much like lead-acid batteries, with a fluid that reacts with electrodes to store charge. However, the liquid is cycled through an external tank in the charge/discharge cycle. The external “refresh” of a flow battery's fluid means it can handle very deep discharges, while lead acid batteries have to be kept above 50 per cent charge. For a static application like storage from solar power, that makes flow batteries an attractive third alternative to both lead acid and  lithium batteries . Harvard's research is on improving the electrolyte, so the external tanks can store more energy per unit of volume, and that's where the vitamin B2 molecule comes in. The university had previously worked on naturally-occurring quinones in the electrolyte; B2 is similar, they say, but uses nitrogen as the electron carrier. The important molecule in B2 i

LG Chem Unveils New Battery Storage

LG Chem, the South Korean company with the biggest share of the grid-connected battery storage market in Australia, has released its new generation systems, promising they will offer more choice, and be cheaper, smaller, lighter, and with improved aesthetics. LG Chem, which claims nearly half of the nascent but rapidly growing Australian grid-connected market, is offering low voltage and high voltage options to Australian households, with its new battery storage systems ranging from a stackable 3.3kWh lithium-ion system to a 9.8kWh system. The three low-voltage battery systems (48 volt) are being offered in 3.3kWh, 6.5kWh and 9.9kWh units, while 7kWh and 9.8kWh high voltage (400 volt) battery systems are also being offered. The new series of battery storage systems will be offered globally but will be launched in Australia first as it remains the most attractive market for  battery storage  because of its high electricity prices, tariff structure, high levels of rooftop solar (now

Solar City Keys On Battery Storage

Image
Elon Musk’s plan for Tesla Motors Inc. to acquire SolarCity Corp. hinges on a symbiosis that doesn’t exist. At least not yet. The key to the proposed $2.86 billion takeover is combining Tesla’s electric cars and wall-mounted  battery units  with SolarCity’s rooftop panels, letting homeowners store solar power to use at night. Here’s the catch: Creating this end-to-end energy company would negate the main financial incentive for rooftop panels. Utilities let consumers sell power into the grid at rates generous enough to cover most or all of their utility bills. That benefit, known as net metering, loses its value when electricity is instead squirreled away in a Tesla battery. Musk has said the combination will make economic sense within five years. “The value proposition for solar plus storage is at odds with net metering,’’ said Ravi Manghani, director of energy storage at GTM Research. Tesla announced the friendly offer to acquire SolarCity June 21, and the solar company’s board is

The World's Largest Storage Battery

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
