Survey: How should smart grids be implemented?
PV integration in smart grids is a complex but highly relevant issue, with various aspects to be considered to develop different scenarios. Researchers in the IEA-PVPS Task 14 program are conducting a survey to collect opinions from peers in the PV branch to perform such an analysis.
California aggregator to buy capacity from compressed air storage project
Under a 25-year agreement valued at nearly $1 billion, a community choice aggregator has agreed to purchase 200 MW of eight-hour energy storage from Hydrostor’s planned 500 MW facility in California.
The case for flywheel storage in the Philippines
An international research team is assessing the potential of flywheels for renewables storage in the Philippines. They considered the use of a flywheel energy storage system developed by US-based Amber Kinetics.
Lithium sulfur flow battery with 250 Wh/L energy density
Edinburgh-based energy storage solutions specialist StorTera has developed a long-duration, energy-dense, lithium-sulfur-based single liquid flow battery (SLIQ). The tech is said to last for 30 years with minimal degradation.
Israel’s behind-the-meter storage market to hit turning point in 2023
Israel’s market for behind-the-meter energy storage projects could grow significantly this year, due to new regulations and plans to commission new solar-plus-storage installations that were tendered a few years ago.
Video: Energy Vault CEO discusses LCOS, novel gravity-based storage design
Robert Piconi, CEO of gravity storage specialist Energy Vault, makes the case for the US company’s long-duration energy storage solutions as an alternative to lithium-ion batteries, and discusses the ideal project size from an economic perspective.
Gravity storage system based on linear electric machines
South African scientists have designed a novel gravity energy storage system that uses linear electric motors to vertically move multiple solid masses to store and discharge electrical energy. They say its levelized cost of storage (LCOS) is $137.20/MWh, but with efficiency improvements, it could drop to about $100/MWh
