      Hydrostor Comes Ashore to Turn Old Coal Plants into Compressed-Air Storage

      Hydrostor is evolving into a land creature. The Toronto based company began its corporate life developing compressed air energy storage projects in deep water. In a 2015 pilot project with Toronto Hydro, Hydrostor used off-peak energy to compress air in underwater balloons two miles off shore in Lake Ontario. The balloons can be deflated later with the aid of water pressure to generate power at times of high demand.

      Pathways to Terawatts of Solar Power and Gigawatt-Hours of Energy Storage | Greentech Media

      The annual potential of solar energy far exceeds the world's per-year energy consumption, but the goal of using the sun to provide a significant fraction of global electricity demand is far from being realized. Scientists from the U.S. Department of Energy's National Renewable Energy Laboratory and their counterparts from similar institutes in Japan and Germany, along with researchers at universities and industry, assessed the recent trajectory of photovoltaics and outlined a potential worldwide pathway to produce a significant portion of the world's electricity from solar power in the new Science paper, "Terawatt-Scale Photovoltaics: Trajectories and Challenges.

      More than a tenth of a 250MW energy storage procurement by utility Southern California Edison will comprise of Ice Energy’s Ice Bear units, deployed in partnership with NRG Energy. Southern California Edison’s (SCE) choice to procure the energy storage was made in 2014, described at the time by California Energy Storage Alliance (CESA) executive director Janice Lin as a “monumental decision”. The procurement was awarded to five companies, AES Energy Storage (100MW), Stem (85MW), Advanced Microgrid Solutions (50MW), Ice Energy Holdings (25MW) and NRG (0.5MW).

      Inside GE and SoCal Edison's First-of-a-Kind Hybrid Peaker Plant With Batteries and Gas Turbines

      Southern California Edison and General Electric have taken a grid edge concept -- integrating natural gas-fired turbines and batteries -- and turned it into two working models. Last month, SCE started operations at the second of two of its new hybrid electric gas turbine (EGT) units -- GE’s term for its combination of turbines, batteries and power controls installed at the two sites. Each peaker plant is in the 50-megawatt range, and is outfitted with a set of batteries capable of providing 10 megawatts and 4 megawatt-hours of power.

      California Utilities Try to Shift to Solar Storage… Tesla's Helping

      We have long lamented that while solar energy production is a mature generation technology that should be used in nearly the entire U.S., the inability of our electronic grid in much of the country to store solar-generated energy limits its use to when the sun is shining. This almost always requires a backup (usually burning natural gas) for those hours when the sun does not shine.

      Duke Energy Partnership with City, County May Avoid Third Power Plant

      ASHEVILLE — Momentum is building in the effort to avoid construction of one of three natural gas plants Duke Energy planned to build that would replace the coal plant on Lake Julian. At Tuesday’s joint City Council and County Commissioners meeting, members of the Energy Innovation Task Force, comprised of local government as well as representatives from Duke Energy, and Rocky Mountain Institute announced that they have begun to research options for the taxpayers and for the environment. They hope to present a two-year plan in the next few months before the City Council hears budget proposals.

      First Solar Proves That PV Plants Can Rival Frequency Response Services From Natural Gas Peakers

      Last summer, First Solar and California grid operator CAISO ran a set of tests to show that utility-scale solar PV, instead of being a disruptive influence on the power grid, could actually help stabilize it. Over a series of days in August, First Solar slightly curtailed power output at a 300-megawatt solar farm in California, enabled its array of inverters, and plugged into CAISO’s system. It then orchestrated the plant’s output to follow CAISO’s automatic generation control (AGC) signals, respond to its frequency regulation commands, and use inverters for voltage regulation, power factor regulation and reactive power control.

      Battery-Powered in Escondido

      The nation's largest battery storage for energy is being constructed in Escondido — part of the shift away from fuel-burning power plants to cleaner energy, which can't be switched on when needed. San Diego Gas & Electric has contractors building the 30-megawatt lithium-ion array on the 1.5-acre Escondido lot that the company already owns. There's already a substation in that industrial park tucked into the southwest corner of where the SR-15 intersects Highway 78 (a second, 7.5-MW storage plant is being sited in El Cajon). The facility will contain 24 steel cabinets of lithium-ion batteries that can hold about 1.25 megawatts each.

      The deal is part of Centrica's wider plans to build a series of flexible power facilities, having secured 15-year agreements for over 500MW of new capacity, mainly gas-fired. The battery storage plant, which will be built at Roosecote in the north-west of England, will provide energy in response to peaks in demand. Roosecote is a large site having originally been built for a coal-fired plant, which has been retired. A gas power plant at the site was demolished in 2015.

      It’s because of the Aliso Canyon disaster. Southern California Edison’s struggles after the closing of a key natural gas reservoir following a massive leak last year has led it to none other than electric car maker Tesla. Tesla on Thursday announced that it had won a deal to provide 20 megawatts of batteries to the utility to plug into one of its substations and provide energy during peak grid times. Tesla says the large battery installation would be able to provide enough power for 2,500 homes daily or 1,000 Tesla cars.

    19. To Beat City Heat, Use an 'Ice Battery'

      To Beat City Heat, Use an 'Ice Battery'

      Famously, Americans are the world’s most extravagant consumers of artificial cooling: We use more electricity for air-conditioning than the entire continent of Africa uses for, well, everything. And as global heat records keep falling and summers get longer and hotter—and as the use of A/C proliferates worldwide—that demand will continue to surge. The challenge of keeping cities livable as we chug toward our Venusian future is complicated by the fact that A/C use fuels rising temps, both directly and indirectly. To handle the increased power demands of hot summer days, utilities need to fire up those dirty, carbon-intensive “peaker plants” that emit an extra dose of climate-addling gases. Plus, because the electrical grid can’t just store the extra juice we need to crank the A/C when a heat wave comes, an enormous amount of energy is wasted on rarely needed capacity. “We have twice as much transmission as we need to meet our needs, if we were using it at a steady rate, day and night,” says Mark MacCracken, CEO of CALMAC, a New Jersey firm that specializes in thermal energy storage.

      A Texas Startup's Big Energy Idea: Storing Electricity Underground

      In a field in Central Texas, Aaron Mandell and his crew are running pumping equipment to bring a former oil and gas well back to life. But they’re not trying to extract black gold. Instead, they are developing a way to turn abandoned oil and gas wells into vaults for storing electricity. The concept behind Mandell’s startup, Quidnet Energy, sounds simple: pumping water deep into the earth to fill up the cracks in-between rocks that previously held fossil fuels. When the pressurized water is released, it acts like a spring as it races through a turbine-generator above ground, powering it to produce electricity.
