Energy Storage

Australian investment manager Infrastructure Capital Group has stepped into the solar energy sector with the acquisition of a majority stake in a ~300 MW solar PV and energy storage portfolio from clean technology developer and investment firm Providence Asset Group.

Australian renewable energy developer Maoneng’s 240 MWp/480 MWh big battery project proposed for Victoria’s Mornington Peninsula is a step closer to realisation after it secured development approval from the state government.

Two Western Australian government funded studies into the transmission and storage of hydrogen have shown that the state’s main gas pipeline is, for large sections, ready for 9% hydrogen blending. However, in less promising news, another study found that the state’s underground storage capacity, including depleted oil and gas fields, are not proximate to the proposed 50GW Western Green Energy Hub or the 23GW Asian Renewable Energy Hub.

India’s production-linked incentive scheme for advance-chemistry battery cell production has received bids for 2.6 times more than the 50 GWh of manufacturing capacity it plans to allocate.

French renewables developer Neoen has started early works on its Goyder Renewables Zone, just north of Adelaide in South Australia. When completed, the project is likely to be the country’s largest wind, solar and battery storage project.

Western Australian renewables company Global Energy Ventures is steaming ahead with its plan to establish a massive 2.8 GW green hydrogen production and export facility on the Tiwi Islands off the coast of the Northern Territory, announcing it has already commenced the development program.

A Japanese group has developed a storage system with potential applications in residential storage, electric vehicles, drones and Internet-of-Things devices.

Scientists in the United States have proposed to use a thermochemical energy storage (TCES) technique that stores energy in chemical bonds to recover the heat produced during air compression operations. According to them, this innovation may increase the round-trip efficiency of compressed air energy storage to 60%.

Current price signals to distributed battery owners “do not align with grid value,” says a study from the Lawrence Berkeley Laboratory.

A new underwater battery storage technology is coming from Netherlands-based Ocean Grazer to address the issue of offshore long-duration storage. The company’s Ocean Battery is touted as innovative yet simple, based on existing technology, and capable of enhancing marine life along the way.
