      Zinc-Air Batteries Provide Power in Remote Areas

      NEW YORK — Remote villages in Africa and Asia are receiving electricity using a little-known type of technology: zinc-air batteries. The goal is to provide a battery that can capture renewable energy and store it for later use. California-based NantEnergy said Wednesday it has created a rechargeable zinc-air battery storage system that can provide power at a lower cost than lithium-ion systems.

      Rethinking Electric Power, Prompted by Politics and Disaster

      SEATTLE — Lilo Danielle Pozzo, who teaches chemical engineering at the University of Washington, grew up in Puerto Rico. So when Hurricane Maria devastated the island in September, it felt, she said, like a perfect alignment of needs and expertise: Professor Pozzo studies batteries and electrical storage systems at the university’s Clean Energy Institute, and Puerto Rico, a place she loves, had just seen its power grid destroyed.

      A Big Test for Big Batteries

      ESCONDIDO, Calif. — In Southern California in the fall of 2015, a giant natural gas leak not only caused one of the worst environmental disasters in the nation’s history, it also knocked out a critical fuel source for regional power plants. Energy regulators needed a quick fix. But rather than sticking with gas, they turned to a technology more closely associated with flashlights: batteries. They freed up the utilities to start installing batteries — and lots of them.

      Indian Point Nuclear Power Plant to Close by 2021

      The Indian Point nuclear plant will shut down by April 2021 under an agreement New York State reached this week with Entergy, the utility company that owns the facility in Westchester County, according to a person with direct knowledge of the deal. Under the terms of the agreement, one of the two nuclear reactors at Indian Point will permanently cease operations by April 2020, while the other must be closed by April 2021. The shutdown has long been a priority for Gov. Andrew M. Cuomo, who — though supportive of upstate nuclear plants — has repeatedly called for shutting down Indian Point, which he says poses too great a risk to New York City, less than 30 miles to the south.

      Rick Perry, Ex-Governor of Texas, Is Trump’s Pick as Energy Secretary

      WASHINGTON — President-elect Donald J. Trump plans to name the former Texas governor Rick Perry as his secretary of energy. The selection of Mr. Perry to lead the energy agency would offer a rich irony: During a televised debate in 2011, when he was seeking the Republican nomination, Mr. Perry intended to list the Department of Energy among agencies he wanted to eliminate, but he could not remember its name.

      LG Chem to Enter U.S. Home Battery Market With Sunrun Deal

      LG Chem Ltd, the world's largest automotive battery maker, will enter the fledgling U.S. market for home energy storage through a partnership with rooftop solar company Sunrun Inc, the companies said on Wednesday. The move will put LG in direct competition with electric car maker Tesla Motors Inc, which unveiled its own home battery packs, called Powerwalls, last year. Sunrun has been using Tesla batteries in its home storage systems in Hawaii since earlier this year, and this deal will add LG to its list of suppliers.

      Batteries and Renewable Energy Set to Grow Together

      Batteries have long been seen as one of the main ways to work more renewables into the electrical grid, by storing electricity during times of excess generation and releasing it when needed. Now, spurred by mandates in California and other states to deploy storage, by the rise of rooftop solar systems, and by falling prices as Tesla Motors and other companies make plans to produce vast numbers of lithium-ion cells, batteries are set to play a significant part in the nation’s power supply.

      Energy-Storage Plans Gain Ground in California

      In an unusual competition in California, proposals for energy storage systems beat out hundreds of bids to construct new power plants as a way to meet peak power needs. Southern California Edison has retired its San Onofre nuclear reactors and is planning to retire natural gas units with environmentally troublesome cooling systems. So it invited proposals for storage — including conventional batteries and giant ice packs — and new gas-fired power plants. To the surprise of the utility and even the storage companies, in many cases storage won. Demand response, or agreements with customers who volunteer to be unplugged at certain times, also did well.

      Energy for a Rainy Day, or a Windless One

      With new energy supplies and demand growing rapidly worldwide, companies in the United States, Europe and across the developing world are spending billions of dollars each year on new power plants, wind turbines and solar panels. Now the focus is increasingly on how to store the bonanza, so that electricity generated from the likes of renewables can be quickly pumped into a country’s energy network as demand skyrockets — say, when people return home from work. To meet global climate change commitments, the International Energy Agency recently called on the United States, the European Union, China and India to invest a combined $380 billion in energy storage by the middle of the century.

      Project Tests New Storage for Energy

      No one at the equipment lot here would blame you for failing to notice the drab green box sitting across from the spare transformers. But the lithium ions inside that refrigerator-size container are part of a wave of energy storage technology that could help Texas revolutionize its electric grid. Oncor, the state’s largest transmission company, is installing five of the batteries this summer in South Dallas neighborhoods, providing backup power to schools, traffic lights and a fire station. With the capacity to each store 50 kilowatts of electricity — enough to power three to five houses for three hours — the batteries are designed to kick in when the electricity trips off, whether because of a falling branch or equipment issues.

    12. Ice or Molten Salt, Not Batteries, to Store Energy

      Energy storage is crucial to transforming the electric grid into a clean, sustainable, low-emissions system, the experts say. And it’s happening already, just not the way most consumers would expect. The simplest idea for storage — charging up batteries at night when there is a lot of wind energy and not much demand for it, or at midday when the sun is bright — is years from being feasible, according to the experts.

      Car Companies Take Expertise in Battery Power Beyond the Garage

      As more homeowners generate their own electricity from solar panels, they still need power from a utility after the sun goes down.  Now, automakers say they may have an answer, by storing that carbon-free energy in electric car batteries for later use.  Honda on Tuesday is introducing an experimental house in this environmentally conscious community to showcase technologies that allow the dwelling to generate more electricity than it consumes.  It is one example of the way solar companies and carmakers are converging on a common goal: to create the self-sufficient home, with a car’s battery as the linchpin.
