Scientists in South Korea have developed a new way to store energy that also offers a solution to a growing environmental problem. Reporting their findings in the IOP Publishing journal Nanotechnology, the research team successfully converted used cigarette butts into a high performing material that could be integrated into computers, handheld devices, electric vehicles and wind turbines to store energy. According to the study, this material outperforms commercially available carbon, graphene and carbon nanotubes. It may someday be used to coat the electrodes of supercapacitors: electrochemical components that can store extremely large amounts of electrical energy. "Our study has shown that used cigarette filters can be transformed into a high performing carbon-based material using a simple one step process, which simultaneously offers a green solution for meeting the energy demands of society," says co-author Professor Jongheop Yi of Seoul National University.

Ryan Wallace for The Science Times: Known as the "Powerwall", Tesla's newest invention is a thin, wall-mounted battery that is the size of a flat screen TV. And with this new battery home owners who have already invested in solar power will be able to entirely go off the grid, and even to sell their excess solar juice back to energy companies. Developed in conjunction with the lithium-ion batteries that Tesla uses for its electric vehicles, the Powerwall unit is an inexpensive unit, only running $3,000 to $3,500, and with it Musk and his companies believe that humans may one day be able to transition to solely using energy derived from the Sun. Though the installation may look like an artpiece, it packs quite a punch at 10 kWh, and with it consumers will not only be able to store their energy for dark solar-free nights, but also more efficiently contribute to global energy use by contributing carbon-free energy back into the mix.
Late Thursday night in Los Angeles, Tesla announced "Tesla Energy," described by the company in a statement as "a suite of batteries for homes, businesses, and utilities fostering a clean energy ecosystem and helping wean the world off fossil fuels." The statement continued: "Tesla is not just an automotive company, it’s an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation." Tesla CEO Elon Musk made the official announcement onstage at the company's design studio in Hawthorne, CA, just south of LA. The home battery, call the "Powerwall," is intended to store solar energy and enable customers to bank grid electricity from non-peak periods and use it during peak times, saving money. It looks "like a beautiful piece of sculpture," Musk said. You can order it now, and it comes in different colors. "The Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for load shifting, backup power and self-consumption of solar power generation," Tesla said. "The Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receives dispatch commands from a solar inverter. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve."

Toshiba Begins Operation of Independent Energy Supply System Utilizing Renewable Energy and Hydrogen
Toshiba Corporation announced the start of demonstration operation of H2One, an independent energy supply system based on renewable energy and use of hydrogen as a fuel for power generation. Kawasaki City and Toshiba have installed the system at the Kawasaki Marien public facility and Higashi-Ogishima-Naka Park in the Kawasaki Port area. H2One combines photovoltaic installations, storage batteries, hydrogen-producing water electrolysis equipment, hydrogen and water tanks, and fuel cells. Electricity generated from the photovoltaic installations is used to electrolyze water and produce hydrogen, which is then stored in tanks and used in fuel cells that produce electricity and hot water. Since H2One uses only sunlight and water for fuel, it can independently provide electricity and hot water in times of emergency, even when lifelines are cut. Kawasaki Marien and Higashi-Ogishima-Naka Park, a municipal facility to promote Kawasaki Port, is a designated emergency evacuation area. In times of disaster, H2One will use stored hydrogen to provide an estimated 300 evacuees to the site with electricity and hot water for about one week. The H2One system is housed in a container, and can be transported to disaster-hit areas on trailers.
Ice Energy has been awarded a five-year contract from Riverside Public Utilities to provide 5 megawatts of behind-the-meter thermal energy storage using Ice Energys proprietary Ice Bear system.
Professor Donald Sadoway remembers chuckling at an e-mail in August 2009 from a woman claiming to represent Bill Gates. The world’s richest man had taken Sadoway’s Introduction to Solid State Chemistry online, the message explained. Gates wondered if he could meet the guy teaching the popular MIT course the next time the billionaire was in the Boston area, Bloomberg Markets magazine will report in its May issue. “I thought it was a student prank,” says Sadoway, who’s spent more than a decade melting metals in search of a cheap, long-life battery that might wean the world off dirty energy. He’d almost forgotten the note when Gates’s assistant wrote again to plead for a response. A month later, Gates and Sadoway were swapping ideas on curbing climate change in the chemist’s second-story office on the Massachusetts Institute of Technology campus. They discussed progress on batteries to help solar and wind compete with fossil fuels. Gates said to call when Sadoway was ready to start a company. “He agreed to be an angel investor,” Sadoway says. “It would have been tough without that support.” Sadoway is ready. He and a handful of scientists with young companies and big backers say they have a shot at solving a vexing problem: how to store and deliver power around the clock so sustainable energies can become viable alternatives to fossil fuels. How these storage projects are allowing utility power customers to defect from the grid is one of the topics for debate this week at the Bloomberg New Energy Finance conference in New York. Today’s nickel-cadmium and lithium-ion offerings aren’t up to the task. They can’t run a home for more than a few hours or most cars for more than 100 miles (160 kilometers). At about $400 per kilowatt-hour, they’re double the price analysts say will unleash widespread green power. “Developing a storage system beyond lithium-ion is critical to unlocking the value of electric vehicles and renewable energy,” says Andrew Chung, a partner at Menlo Park, California–based venture capital firm Khosla Ventures.
As fuel cells continue to increase sales and installations in existing markets and prove themselves in others, companies in synergistic energy technology sectors will hopefully consider joining FCHEA to become more involved in the industry.
From Benzinga: Global Equities Research analyst Trip Chowdhry has revealed some interesting information about Tesla Motors Inc 's new product line. Outside of the fact that it will not be a car, very little is known about what Tesla plans to announce. Some experts think it could be a motorcycle. Others assume that it will be an in-home battery that involves solar energy. If Chowdhry's information is correct, it seems that Tesla is ready to launch the latter. In a note to investors, Chowdhry said that he knows of two people that own a residential battery from Tesla. He spoke to one of those owners and detailed the following bullet points: "There are about 230 Households in California, who currently have Tesla Stationary Battery installed in their Homes. Another about 100 Households are out of California. This customer had the Tesla Stationary Battery for about One and a Half years, and is installed in his garage." Last year, Chowdhry attended a sustainability conference and learned that Google Inc is "widely believed" to have a few Tesla (commercial-grade) batteries in some of its buildings. Apple Inc. might also purchase some of these batteries for its new campus. Chowdhry believes that Tesla's commercial-grade batteries are rated at more than 400 kWh.
Friday's solar eclipse highlights the importance of energy storage to the continued growth of solar, experts have claimed. Energy consultancy Frost & Sullivan estimate that by covering 85% of the sun; the eclipse removed 35GW of solar power from the European grid - equivalent to 80 conventional power plants. This sort of instability will drive generators to invest in better storage facilities to ensure a constant security of supply, according to the consultants. "Dealing with events like this one requires investment in various storage tools and monitoring techniques which create a certain amount of flexibility in the energy system," said the report. The nascent technology of pump storage - pumping water uphill into large reservoirs when power is abundant and then letting it flow down again to generate power when needed - will reportedly be valuable in preparing for the eclipse in Germany.
A South Australian solar energy company is in talks with 'major developers' to build energy self-reliant housing estates which don't need to be connected to the main electricity grid.
Just imagine, a super grid will allow Norway's hydro-power to light up a restaurant in Italy, Belgium's wind farms to provide power to a home in U.K., and Saharan solar power plants to run a factory in Germany.
