    1. The Renewable Electricity Grid: The Future Is Now

      The Renewable Electricity Grid: The Future Is Now

      A New World Bank report finds that with the right policies and investments, countries can integrate high levels of variable renewable energy such as solar and wind into their power grids without compromising the reliability or affordability of electricity. The report focuses on the complementary role of natural gas and energy storage in electricity grids that draw on high levels of solar and wind.

      Mining Sector Eyes Microgrids and Energy Storage to Reduce Diesel

      Energy storage looks to be the logical next step for a growing number of mining companies using renewables to offset high power costs. Last year saw at least two major mining firms announcing storage projects amid a rush to install solar and wind generation. Both projects are taking place in very different environments. Glencore plans to use a combination of storage technologies, including hydrogen and a flywheel, for wind power in Arctic conditions, while Rio Tinto Alcan will be using batteries for PV in the Australian outback.

      California PUC Aims to Replace Shuttered Nuclear and Gas With More ‘Preferred Resources’

      The California Public Utilities Commission (CPUC) made a proposed decision on Friday that denied approval of a new gas-fired power plant in the coastal Southern California city of Carlsbad. According to the PUC, approval for the plant was denied because the utility, San Diego Gas & Electric (SDG&E), did not sufficiently consider "preferred resources," meaning renewable energy, efficiency measures, demand response, and energy storage.

      Countertop Flow Battery Is Coal-Crushing Energy Storage

      In tight urban spaces where land is at a premium, the opportunities for large-scale local energy storage are rare. Lithium-ion batteries could provide a solution, but although the technology has a good safety record in autos and portable devices, scaling them up for community use in densely populated areas typically presents a hazard best avoided if at all possible. That’s where flow batteries come in.

      SDG&E Integrates EVs and Energy Storage into California’s Energy and Ancillary Service Markets

      San Diego Gas & Electric is actively bidding a group of energy storage systems and electric vehicle fleets as one resource directly into the California Independent System Operator’s (CAISO) energy markets. These markets include those that address short-term imbalances in electricity supply caused by such things as intermittent renewable energy. The achievement ranks SDG&E as one of the first utilities to integrate electric vehicles (EVs) into California’s wholesale energy market.

      SDG&E Receives $5 Million Grant To Expand Borrego Springs Microgrid

      The California Energy Commission (CEC) recently awarded San Diego Gas & Electric (SDG&E) a nearly $5 million grant to expand the innovative Borrego Springs Microgrid. The grant will allow the Microgrid to use the nearby 26-megawatt (MW) Borrego Solar facility to power the entire community, making this one of the nation's largest microgrids that can operate solely on renewable energy. In addition to bringing in more clean power, the funding will be used to increase the size of the Microgrid to service all of Borrego Springs, further enhancing local reliability and reducing the duration of power outages.

      Biobatteries: Taking Battery Technology to the Next Level

      There’s a good chance that the electric battery of the future will have biobased aspects to them — or may even be powered by a biofuel. If you’ve been following the long-standing competition between electric and fuel-powered cars, you’ll know the basics. That electric motors have better efficiency than internal combustion engines, but electric cars have short ranges because batteries lack the energy density of liquid fuels, are heavy, and expensive, and take a long time to re-charge.

      Citigroup Predicts Battery Storage Will Hasten Demise Of Fossil Fuels

      Investment bank Citigroup predicts that the wide deployment of battery storage technologies will hasten the demise of fossil fuels across the globe in the coming decade, including oil, coal and gas. And it also warns that the battery phenomenom will be even more profound than the solar revolution currently sweeping the globe, and will sweep aside any traditional utilities that remain focused on centralised generation.

      How One Company Plans to Store Wind Energy in Giant Balloons Under Lake Ontario

      Under an unassuming building on the edge of Toronto Island, a 30-centimetre steel pipe extends deep underground before jutting out into Lake Ontario. The pipe stretches nearly four kilometres to a series of unworldly fabric balloons packed full of compressed air. Toronto energy start-up Hydrostor has come up with an inventive use for the balloons. Redeployed as part of a system to make renewable energy more reliable, this “air-cavity” technology will help cities peak their power supply on high-usage days.

      Salt Caverns in Eastern Alberta Created to Store Energy

      Calgary-based Rocky Mountain Power has been working on the Alberta Saskatchewan Intertie Storage Project (ASISt) for a couple of years. Company president Jan van Egteren said because of regulatory procedures, it'll likely be another two or three years before the company actually breaks ground on the project. While using salt caverns for storage purposes is not new – they are often used to store liquid petroleum products such as butane, as well as the by products of oil production. What is new is employing the caverns to store wind energy.

      Hydrogenics Corporation will supply a 1MW electrolyzer and provide engineering expertise to a consortium of companies working on the European project MefCO2 (methanol fuel from CO2) in Germany. The application will take excess electricity from intermittent renewable energy sources, generate green hydrogen, and then create methanol using a low-carbon footprint production plant and carbon dioxide emissions from an existing coal-fired power plant in Essen, Germany owned by STEAG Gmbh, which operates a number of regional power plants and distributed energy facilities.

      Dominion Virginia Power filed an application with the Virginia State Corporation Commission today to build Virginia's first large-scale solar facility. The 20-megawatt project would be built on approximately 125 acres of land owned by the company near the Remington Power Station in Fauquier County. The facility would contain approximately 90,000 photovoltaic panels and at peak capacity would generate enough electricity to provide power for 5,000 homes. The estimated in-service date for the facility is October 2016.

      Meet the 27-year-old Inventor Backed by Bill Gates and Peter Thiel

      Scientist Danielle Fong, 27, has been running her company LightSail Energy for six years and has yet to bring a product to market. In fairness, she is trying to create something that has never been built before—something that could revamp the power grid. LightSail’s aim is to compress air to create heat and then use that to power, well, just about anything that needs it. This energy would be cheaper and cleaner than fossil fuels and would allow renewables sources, like wind and solar, to be stored for later use. To harness the energy, LightSail injects a mist of water spray into the air, which absorbs the heat energy, and allows it to be stored in a shipping container system or underground caverns.

      Our Voice: We're Charged Up About IID's $68M Battery

      Imperial Irrigation District’s massive investment in the local energy grid in the form of a $68 million “battery” is a good sign for renewables. Officials say the project will help bring about production of 50 megawatts of energy from two solar projects — the 30-megawatt Midway III project in Calipatria and the 20-megawatt SunPeak 2 project near Niland. “The battery is a really big deal,” Bruce Townsend, the district’s superintendent for alternative energy, told The Desert Sun’s Sammy Roth. “If we didn’t have the battery ... we would need to procure another gas unit, and get it permitted, and burn fossil fuels.”

      High-speed flywheels, turbines that run off compressed air stored in caverns, super-sized versions of a cellphone battery ...In the sixth-floor ballroom of a downtown Austin hotel earlier this month, power executives from around the country filed in as companies pitched a stream of technologies to store electricity. It sounded promising. Reduce the grid’s notorious inefficiency and provide backup for weather-susceptible wind and solar farms. But the same spiel had been kicking around for decades. And the expense was huge when compared with all that cheap coal and natural gas waiting underground.
