      Storing Energy in Underwater Balloons

      A RANGE OF ENERGY storage options is becoming increasingly available to respond to the growing share of renewables on the grid. But batteries alone may not address all of the potential needs for power reliability -- particularly as peak demand calls for power often at the times that renewables are least able to respond. Enter Hydrostor, a Canadian startup that has launched the world's first underwater compressed-air energy-storage solution. Hydrostor recently brought online a grid-connected, 1-MW system using inflatable balloons positioned 180 feet below the surface of Toronto's Lake Ontario. The system -- capable of holding enough energy to power 330 homes -- will be operated by Toronto Hydro. The utility intends to use the Hydrostor system to store electricity during offpeak hours and then tap into it as demand grows

    4. Clean Energy is Winning the Race Against Fossil Fuels — but the Planet is Still Losing

      Clean Energy is Winning the Race Against Fossil Fuels — but the Planet is Still Losing

      A new United Nations report has found that 2015 set a slew of new records for global investment in clean energy — and furthermore, the bulk of investment was not in places like the United States or Germany but rather in the developing world. But the report also contained a grim punchline when it came to the impact this is having on the broader climate change problem. The world invested an unprecedented $286 billion in clean energy in 2015, the report found — and with that money purchased a similarly unrivaled 118 gigawatts (or billion watts) of new wind and solar photovoltaic electricity generating capacity, among other installments. More than half of all new generating capacity in 2015 was in renewables, another new record.

      SDG&E Seeks Energy Storage, Renewable and Other Clean Energy Resources

      SAN DIEGO, March 7, 2016 -- San Diego Gas & Electric (SDG&E) announced it is seeking up to 140 megawatts (MW), of new "preferred energy resources," including energy storage, renewable energy, distributed generation, energy efficiency and demand response. The solicitation for additional preferred energy resources builds upon SDG&E's significant investments in clean energy. The utility currently has more than 60 renewable contracts representing more than 2,400 MW of renewable energy, the equivalent of powering more than 700,000 San Diego homes for a year. In 2015, SDG&E became the first California utility to supply its customers with a third of its energy, 33 percent, from renewable resources. "We're not only committed to reducing air emissions and meeting California's climate goals, we're leading the way," said SDG&E's Chief Energy Supply Officer, Scott Drury. "Through renewable energy investments, we've helped to advance clean energy technologies resulting in emissions reductions that are comparable to taking more than 250,000 gasoline-powered cars off local roadways."

      SEL Powermax Technology Secures Microgrid Resiliency at UC San Diego

      A new microgrid control solution from Schweitzer Engineering Laboratories (SEL) marks the latest of University of California, San Diego’s ongoing improvements to its campus electrical utility system. The recently installed high-speed islanding detection and load shedding system integrates SEL intelligent controls and adaptive wide-area protection technology with the campus’ onsite generation, load and energy storage. Today onsite generation at UC San Diego covers approximately 85% of the campus’ annual load and 75% of peak demand—a total of approximately 50 megawatts. The remainder is imported from the San Diego Gas & Electric (SDG&E) grid. UC San Diego’s diverse portfolio includes a 2.8-megawatt fuel cell, 2.2-megawatt solar network, a 30-megawatt gas-turbine cogeneration plant, a 2.5-megawatt energy storage system and a chiller plant.

      Crescent Dunes Solar Plant with Molten Salt Energy Storage

      SolarReserve's Crescent Dunes Solar Energy Project is a utility-scale solar power plant with fully integrated energy storage technology. Using the sun’s energy, and requiring no fossil fuels, the project delivers electricity on demand, much like a coal, oil, natural gas or nuclear power plant, except with zero emissions, no hazardous waste and low water use. The Crescent Dunes project, located near Tonopah, Nevada, generated its first test electricity in the fall of 2015 after completing synchronization with the grid. Full load electricity generation at 110 megawatts of net electricity output has been achieved and the project has passed the necessary test to reach full commercial operation under its 25-year Power Purchase Agreement with NV Energy, Nevada’s largest electric utility. Consistent with the rollout plan, the facility will ramp up to its full annual output over the coming year.

      Electricity in the United States is going through massive changes: the generation mix is shifting rapidly, regulatory and industry models are evolving, and policy is playing an ever important role. All of these changes can be hard to conceptualize, particularly when trying to make sense of how multiple factors interact with each other. No one map can display everything about our grid, but geography is key to understanding the diversity of resource mixes, regulatory regimes, and policies across the country.

      Six Trends that will Shape Electric Utilities in 2016

      2016 looks to be the year that energy storage starts getting deployed widely...As Jim Robo, CEO of Juno Beach, Florida-based NextEra Energy Inc., noted in September, he expects energy storage prices to fall at such a rate that after 2020 new storage will supplant new natural gas plants as a way to meet peak demand. That's only one of many uses foreseen for energy storage, whose proponents say it also will allow consumers not just to store electricity from rooftop solar generation units, but to reduce the amount of power they purchase during their peak demand times and keep their lights on during blackouts.

      Southern California Edison is embracing energy-storage technology over the natural gas-fired peaker plants that utilities have traditionally relied upon to meet sudden shortfalls in electricity.  “If the requirement is just, ‘Hey we’re just short energy or capacity,’ then yes, energy storage is going to be the solution before probably a peaker,” Colin Cushnie, vice president of energy procurement and management, said in an interview at the utility’s office in Rosemead, California. “We don’t want to put peakers on the grid if cleaner-cost options are available.”

      We’ve been hearing big news from the US energy storage company Greensmith all year, and now there is more big news to report. Last week, Greensmith announced that the UK-based global energy company E.ON has joined in its latest round of financing, bringing the total to $18.3 million. With these two industry leaders joining forces, it’s time to close the book on that old story about wind and solar being inadequate and unreliable. Energy storage is here to stay, and thanks to companies like Greensmith, energy storage systems are getting more sophisticated and effective at managing intermittent sources of electricity.

      How Can We Store More Energy From the Sun and the Wind?

      Storage methods currently being used around the world include batteries, flywheels, geothermal plants, compressed air and hydrogen - even ice. But the the most popular method is hydro power - water pumped to the top of a mountain and then released to power turbines at the bottom. According to research company Navigant, global energy storage capacity is going to rise from about 1,750 megawatts (MW) in 2016 to nearly 11,000 MW by 2020.

      PG&E Presents Innovative Energy Storage Agreements

      Pacific Gas and Electric Company (PG&E) this week expanded its commitment to clean energy by presenting its first 75MW of energy storage contracts to the California Public Utilities Commission for review and approval. California’s Energy Storage Decision requires investor-owned utilities to procure 1,325MW of storage by 2020. PG&E’s share is 580MW. Storage is expected to play an increasingly important role for California utilities as they work to achieve the states ambitious clean energy goals. By the end of 2015, PG&E forecasts that about 30 percent of its retail electric deliveries will come from renewable sources. Energy storage will help integrate many of those resources, such as wind and solar, which are intermittent or provide peak output during times of low demand.
