Utility Scale Storage

Attero to invest $72.4 million in setting up ‘world’s most advanced’ Li-ion battery recycling plant in Telangana

The company already has a state-of-the-art lithium battery recycling plant in Roorkee, Uttarakhand, with a recovery efficiency of more than 98% across various battery materials. It said the new plant in Telangana will increase its Li-ion battery recycling capacity to 19,500 MT by the end of 2023 from the current 4,500 MT.

ABC Cleantech to invest $6 billion in setting up green hydrogen, ammonia facility in Karnataka

ABC Cleantech, a part of Axis Energy Group, will invest around $6 billion (INR 50,000 crore) to build a green hydrogen and ammonia plant, integrated with 5 GW of renewable energy capacity, in the Indian state of Karnataka.

Novel redox flow battery paves way for low-cost storage

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

Tdafoq Energy partners India’s Delectrik Systems for GWh-scale vanadium flow battery plant in Saudi Arabia

Tdafoq Energy will use Delectrik Systems’ technology to manufacture vanadium redox flow batteries in Saudi Arabia. Construction has already started on a manufacturing facility in Saudi Arabia, which will be scaled to a GWh capacity by 2025.

Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market

US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.

PCM-based thermal battery to store solar power via heat pump

Norway’s SINTEF has designed a heat storage system based on phase change materials (PCM) that can support PV generation and peak shaving. The battery’s container hosts 3 tons of liquid biowax based on vegetable oil and is now beating performance expectations at a pilot facility.

Wind, solar payback times under a year in some parts of world, says Rystad

Record energy prices, particularly in Europe, are driving demand for renewables and energy storage. That is changing the equation for utility solar and wind investment and shortening project payback times to under a year in some regions. Storage deployment, driven by recent policy developments around the world, is also expected to get a big boost through to 2030.

The long read: Netting true value from batteries

Net metering reforms in the US are a missed opportunity to harness residential battery storage, argue researchers from the Lawrence Berkeley National Laboratory. Compensation rules for residential rooftop solar are evolving toward a model that encourages customers to use battery storage to maximize solar self-consumption. However, is this a good thing? Galen Barbose, Sydney P. Forrester, and Chandler Miller investigate.
