Germany Just Got Almost All of Its Power From Renewable Energy Bloomberg

Clean power supplied almost all of Germany’s power demand for the first time on Sunday, marking a milestone for Chancellor Angela Merkel’s “Energiewende” policy to boost renewables while phasing out nuclear and fossil fuels. Solar and wind power peaked at 2 p.m. local time on Sunday, allowing renewables to supply 45.5 gigawatts as demand was 45.8 gigawatts, according to provisional data by Agora Energiewende, a research institute in Berlin. Power prices turned negative during several 15-minute periods yesterday, dropping as low as minus 50 euros ($57) a megawatt-hour, according to data from Epex Spot. Countries around Europe are building increasing amounts of renewable capacity in order to r

Forget Elon's Batteries—Fix the Grid With a Rock-Filled Train on a Hill WIRED

THE ARES IS pretty simple, as cutting-edge energy storage technology goes. A lot of rocks. A few railcars that, if they weren’t traveling up and down the same 5.5-mile track on a Nevada hillside, would probably be hauling ore around a mining operation. Throw in an electric generator, and you’ve got the future of the American energy grid. Well, one possible future. Energy storage is a hot topic, because federal and state guidelines are fast pushing utility companies to ramp up their use of renewable energy sources. (California’s supply, for example, has to be 50 percent renewable by 2030.) The problem is, today’s coal and natural gas guzzling grid doesn’t hold onto the electricity it generate

China to boost energy storage 10-fold to cut power waste: industry

China is expected to raise its power storage capacity by ten-fold to 14.5 gigawatts by 2020, as the world's second-biggest economy tries to cut massive waste from renewable energy projects, an industry association said. China is the world largest wind and solar power producer, but some regions are estimated to be losing more than 40 percent of their power because of technical restraints and bottlenecks in the grid, alongside weak power demand growth. Storage technologies, such as pumped storage hydropower or lithium ion batteries, are expected to play a critical role in improving the China's capacity to make better use of renewables. International companies involved in providing storage tech

Alevo, The Other Energy Storage Gigafactory, Begins To Stir

In late 2014, a virtually unknown company called Alevo announced it was entering the energy storage market with a new inorganic, sulfur-based lithium ion battery technology that it had acquired from the bankrupt German company fortu PowerCell. Alevo entered the U.S. with a big splash, investing over $68 million in the 3.5 million-square-foot former Philip Morris tobacco factory in Victory, North Carolina, outside Charlotte. It also announced that it would hire up to 2,500 workers over three years, with a potential maximum workforce of 6,000 capable of turning out thousands of megawatts of electricity storage products annually. In other words, Tesla would not be the only storage company with

How wireless charging works for electric cars, explained...

Today's electric-car drivers are used to plugging them in to recharge, but technology now exists that would allow them to cut the cord. Wireless charging for electric cars is still in its infancy, but it has the potential to make ownership vastly more convenient. Here's a quick explanation of how it works, courtesy of Engineering Explained.
