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

      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.

      Texas utility goes coal-free with solar focus

      Texas and New Mexico-based utility El Paso Electric (EPE) has eliminated coal generation from its portfolio to concentrate on utility-scale solar and a community solar programme. Just two years ago, the company said its future energy supply would come from a mixture of natural gas plants and utility-scale solar after connecting the 50MW Macho Springs PV plant and doubling its utility-scale solar capacity.

      Energy Storage for Renewables can be a Good Investment Today, Study Finds

      Utility companies or others planning to install renewable energy systems such as solar and wind farms have to decide whether to include large-scale energy storage systems that can capture power when it’s available and release it on demand. This decision may be critical to the future growth of renewable energy. The choices can be complicated: Would such a system actually pay for itself through increased revenues? If so, which kind of system makes the most sense, and which features of the system are most important? If not, how much cheaper do storage technologies need to be?

    10. ABB Supplies Control System for World's First Portable Hybrid Microgrid

      ABB Supplies Control System for World's First Portable Hybrid Microgrid

      A pilot system, consisting of 141 kilowatt peak (kWp) of solar PV, was successfully deployed at a construction worker village in remote Queensland, Australia. Within one week of leaving the factory, 1,000km from the village, the system was unpacked and energized, augmenting four brownfield diesel generators and reducing diesel fuel consumption thereafter. After six months of operation, during which ABB’s cloud-based remote monitoring was used, the pilot system was packed up in less than 170 person-hours and successfully relocated. Hybrid microgrid power systems benefit customers in off-grid areas by reducing their dependence on diesel/gas generators, which are expensive to maintain and operate on fuel that must be transported to the site and is subject to volatile pricing. By contrast, solar PV and wind generation are already cheaper than diesel/gas in some off-grid locations and, when complemented with backup or storage technologies, can bring remote operations and communities closer to energy autonomy. They also reduce emissions created by burning diesel/gas fuel.

      The Senate passed the first broad energy bill in nine years on Wednesday, legislation containing modest measures popular with both Republicans and Democrats to modernize the power grid and speed the permitting process for liquefied natural gas exports. The bill, which passed 85-12, attempts to protect the power grid from extreme weather events such as ice storms and hurricanes, and from cyber attacks. It also aims to spur innovations in storage of power from wind and solar energy.

      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

      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.

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."

      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.
