REV Renewables and LS Power Commission First Eight-Hour BESS in California A ribbon-cutting ceremony involving local officials, community leaders, and industry partners marked the recent activation of the Tumbleweed Energy Storage facility in Kern County, California. The project, a collaboration between REV Renewables, its parent company LS Power, and several California Community Choice Aggregators (CCAs),

A municipal council’s rejection of a compressed air energy storage (CAES) project has left a US geothermal startup without vital local support needed to participate in Ontario's energy procurement process. The decision by Bluewater, a municipality in Huron County, Ontario, occurred mid-August and was primarily driven by farmland and land-use concerns. Despite global advancements in

The Ontario Independent Electricity System Operator (IESO) has initiated a Long Lead-Time request for proposal (LLT RFP) to secure up to 800MW of long-duration energy storage, including pumped hydro, and 1TWh of generation resources. Successful projects awarded contracts will have a 40-year agreement. This procurement builds upon the IESO’s previous Long-Term 1 (LT1) and Long-Term

Houston-based Sage Geosystems is pioneering a new approach to long-duration energy storage utilizing deep rock formations instead of traditional dams and reservoirs. The EarthStore system stores power for six to ten hours by pumping water into fractures created within hot, deep rock formations two miles below ground. The pressure from the compressed rock then forces

Chinese researchers have developed a groundbreaking flowing zinc slurry battery capable of retaining 81% of its capacity after 5,500 charge-discharge cycles. This innovation, created by teams at Fudan University and the Chinese Academy of Sciences, addresses long-standing challenges in zinc-based flow batteries by replacing solid zinc electrodes with a circulating slurry of zinc nanoparticles suspended in a conductive liquid. The system achieved a Coulombic efficiency of 99.94%, demonstrating exceptional stability and scalability for long-duration energy storage. The battery's design allows zinc to transition between metallic and ionic forms while continuously circulating between storage tanks and the electrochemical cell, separating energy storage capacity from power delivery. This advancement could revolutionize renewable energy systems by enabling efficient storage of solar and wind power, with potential for expanded energy capacity through increased slurry volume without redesigning the core electrochemical system. The study, published in Nature Energy, highlights the technology's promise for large-scale renewable energy storage solutions.
