Utility Scale Storage

Aluminum-nickel molten salt battery for seasonal renewables storage

US scientists have developed a battery that can retain 92% of its initial capacity over periods of 12 weeks, with a theoretical energy density of 260 W/hour per kg. It was built with an aluminum anode and a nickel cathode, immersed in molten-salt electrolyte.

Japan’s Mitsui to buy 49% in ReNew Power’s round-the-clock project

Japanese investor Mitsui has signed the agreement to raise a 49% stake in ReNew Power’s 1.3GW hybrid renewable energy project supplemented with up to 100MWh of battery storage. The project will supply 400MW of round-the-clock power to the Solar Energy Corporation of India (SECI) under a 25-year power purchase agreement.

Gautam Solar releases gel battery solution for solar storage

India’s Gautam Solar says its gel batteries provide a safer, cost-effective, and long-lasting alternative for the energy storage space.

Solar the energy workhorse in latest gloomy IPCC verdict

Photovoltaics can wipe out 4.25 billion tons of carbon emissions every year this decade, according to the UN Intergovernmental Panel on Climate Change. Even so, the actions announced so far remain way short of what is needed, with capital flows to fossil fuels still greater than the cash directed toward combating climate change.

Australian researchers promise lifespan boost for lithium-ion batteries

Researchers from The University of Queensland have developed a new nanotechnology that purportedly more than doubles the lifespan of high-voltage lithium-ion batteries, paving the way for higher density and lower-cost energy storage solutions.

World will need 5.2TW of solar this decade to avoid climate breakdown

The International Renewable Energy Agency’s latest global outlook has spelled out just how ‘woefully’ far the world is from capping temperature rises at 1.5C, and lamented: ‘The stimulus and recovery efforts associated with the pandemic have also proved a missed opportunity.’

Monolithic fuel cell with power density of 5.6kW/L

An international research group has developed a solid oxide fuel cell that may be used in vehicles. The monolith device has an active cell area of around 18 cm2 and was built through common manufacturing processes. It was found to achieve a high power density of 5.6 kW/L, which the scientists said is comparable with that of the best performing fuel cells based on ceramic anodes.

Australian electrolyzer invention enables green hydrogen under US$1.5/kg by ‘mid 2020s’

“We’re not talking about incremental improvement, this is a really giant leap,” Hysata CEO Paul Barrett told pv magazine Australia. Hysata is commercializing a breakthrough made at the University of Wollongong which effectively, Barrett says, invented a “brand new category of electrolyzer,” vastly improving efficiency.

Investment cycle means race is on to incentivize green hydrogen

A report published by Irena hints the world’s politicians will have to get to work immediately to avoid another generation of fossil fuel-fired hydrogen, ammonia, and methanol plants being set up to run into the second half of the century.

Tata Power DDL, Battery Smart partner to set up battery-swapping network for electric vehicles

The Delhi discom has partnered with battery-as-a-service provider Battery Smart to set up battery swap stations for electric two- and three-wheelers across North Delhi.
