Conceived by Swiss researchers, the battery shows good stability over 50 cycles, with an average energy efficiency of 68% and a water-splitting voltage efficiency of 64.1%. According to its creators, the device produces pure hydrogen that only needs to be dried and compressed for optimal storage.

National Renewable Energy Laboratory researchers have studied which tech offers the lowest levelized cost of energy to provide the US Western Interconnection grid with electricity when wind and solar are not available. They assumed 85% renewables penetration and determined that geologic hydrogen storage and natural gas combined-cycle plants with carbon capture storage are the cheapest options for 120-hour discharge applications. 


The Indian natural resources company is looking to scale up lithium titanium oxide (LTO) anode and lithium ferrophosphate (LFP) cathode material production for electric vehicle batteries as demand rises. It produces these materials using the economical method developed by the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI). The company is also keen on forward integration up to battery assembly.

Lithium-based energy storage volumes are expected to grow by multiple orders of magnitude in the coming years, with a 1,000% capacity increase by 2023.

A new study provides a novel assessment of grid-scale storage deployment in India, both in the near term and the long term. Scenario-based capacity expansion modeling shows when, where and how much storage can be cost-effectively deployed in India through 2050.

Australian researchers have tested a novel lithium salt for high-voltage lithium batteries in electric vehicles and grid-scale storage systems. They claim the salt is less hazardous than conventional battery materials.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

Renewables developer Syncline Energy has revealed plans for a 600 MW/2400 MWh battery storage project near Melbourne.

Battery prices are falling, and renewable energy generation continues to expand, leading power plant developers to co-locate energy storage along with power generation assets.
