Energy Storage

The analysis from Taipei-based intelligence provider TrendForce finds that the average price for lithium iron phosphate (LFP) energy storage system cells continued to slide in August, reaching CNY 0.35/Wh ($0.049/Wh). Meanwhile, demand for large capacity cells continued to grow at a steady pace.

King Abdullah University of Science and Technology researchers have told pv magazine that hydrogen storage pipelines and gravel could become a reality in lakes or water reservoirs in Europe, the United States, Japan, or China within 10 years. “The technology required to implement the proposed system is available, simple and cheap,” they said.

A European research consortium has produced a prototype solid-state battery using a new manufacturing process that reportedly achieves high energy densities and can be implemented on modern lithium-ion battery production lines.

Investment confidence in Australia’s green hydrogen industry has received a $660 million boost following a joint declaration with Germany to negotiate supply chains that guarantee European buyers for Australian products.

Solar Energy Corp. of India (SECI) has started accepting bids to set up 2 GW of renewable energy projects backed with energy storage systems for assured peak supply of 8 GWh. Bidding closes on Oct. 14.

Scientists have proposed a new system that uses surplus PV energy in the spring and the autumn to charge up underground thermal energy storage for later use in the summer and winter. They have simulated it on a school facility in Seoul, with a few optional configurations for thermal storage. Power savings were up to 39%.

The Dengkou Renewable Energy Storage Project is billed as the largest single-capacity energy storage station under construction in China.

The device developed by TU Bergakademie Freiberg researchers uses aluminum as an anode, graphite as a cathode, and a polymer-based solid electrolyte. It is being validated and further developed for industrial production. The goal is storage capacity of 10 kWh.

Developed by a Chinese research group, the novel refrigerant is made of a mixture of carbon dioxide (CO2) and a non-flammable hydrofluoroolefin. It has slightly higher costs compared to conventional compounds, but its creators claims these costs could be significantly reduced with large-scale industrial production.

The US Department of Interior has given the green light to Nevada’s largest solar+storage development, the Libra Solar Project. It has also opened a comment period for the Bonanza Solar Project, which features a 195 MW/780 MWh battery storage system.
