On Wednesday, an energy company headed by the California billionaire Patrick Soon-Shiong announced that it had developed a rechargeable battery operating on zinc and air that can store power at far less than the cost of lithium-ion batteries. … “It could change and create completely new economies using purely the power of the sun, wind and air,” Dr. Soon-Shiong…said.

Making the batteries rechargeable and lowering their cost are seen as important advances in enabling the electric grid to depend on power from renewable sources.
For 100 years, most decisions about the U.S. electric grid have been made at the top by electric utilities, public regulators, and grid operators. That era has ended.
The world’s biggest lithium-ion battery — built by tech billionaire Elon Musk’s company Tesla last year — has survived its first summer in South Australia’s mid-north. And according to a new report by the Australian Energy Market Operator (AEMO), it’s outperforming coal and gas generators on some key measures.
A battle is brewing in southern California between a utility planning to build a new natural gas plant and clean energy advocates who say solar and storage facilities could provide the power for cheaper.
When Eneco, a major Dutch utility, tested a promising energy monitor in several dozen homes, things could not have gone much worse. The company making the devices failed to deliver enough of them, and some of those provided did not work. But when Eneco sent workers to recover the monitors, something strange happened — a tenth of customers refused to open their doors. “They wanted to keep it,” said Tako in ’t Veld, a former Eneco executive who now leads the “smart energy” unit at Quby, the company that makes the energy meter.
America’s energy storage market just had its biggest first quarter in history, and is growing exponentially … Utilities across America are starting to learn storage through pilot projects, and as they install batteries, they realize operational benefits as well as economic benefits from avoided costs across their systems. Once these benefits become apparent, they want to add more storage and create a beneficial cycle of positive outcomes.
Utility Arizona Public Service has contracted for a new grid-scale battery — not to demonstrate the technology, but because it’s a lot cheaper than the conventional alternative.
Recent leaps in battery technology, combined with falling solar power prices and energy-saving advances, mean North Carolina can replace all fossil fuels used for electricity by 2030, and half by 2025… That’s according to a comprehensive new report called NORTH CAROLINA CLEAN PATH 2025: Achieving an Economical Clean Energy Future. NC WARN commissioned the report by veteran energy engineer Bill Powers of San Diego.
Green Mountain Power is trying to turn homes, neighborhoods and towns into virtual power plants, driven by economics as well as environmental goals.
