South Korea’s biggest battery comes online
Korean utility KEPCO has completed a 978 MW battery project that is billed as Asia’s largest battery energy storage system for grid stabilisation purposes.
Most home battery storage systems meet warranty claims, new research finds
It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of usable capacity per year on average, meaning good news for the industry as most warranties in the market can be met with the implementation of capacity reserves.
COP29 to propose 1.5 TW energy storage target by 2030
This year’s UN Climate Change Conference could adopt a target to increase global energy storage capacity more than sixfold by 2030. To achieve this, the world would need to add more than 158 GW of energy-storage capacity annually.
China connects first large-scale flywheel storage project to grid
The 30 MW plant is the first utility-scale, grid-connected flywheel energy storage project in China and the largest one in the world.
Envision pushes energy storage density to new highs with 8 MWh, 20-foot container
Chinese multinational Envision Energy has unveiled the world’s most energy dense, grid-scale battery energy storage system packed in a standard 20-foot container.
Aggreko launches two new C&I battery storage systems
Aggreko has introduced two new mid-sized battery storage solutions – 250 kW / 575 kWh and 500 kW / 250 kWh, looking to meet a variety of on and off-grid applications.
Global energy storage fleet to surpass 1 TW/3 TWh by 2033, WoodMac says
According to the latest forecast from Wood Mackenzie, the global energy storage market (excluding pumped hydro) is on track to reach 159 GW/358 GWh by the of 2024 and grow by more than 600% by 2033, with nearly 1 TW of new capacity expected to come online.
Long-duration energy storage poised to outcompete lithium-ion batteries
While most long-duration energy storage (LDES) technologies are still early stage and costly compared to lithium-ion batteries, some have already, or are, set to achieve lower costs for longer durations, finds BloombergNEF.
Weekend read: Enhancing safety in lithium-ion batteries
Lithium-ion batteries are generally safe and unlikely to fail but they can catch fire if they are damaged or stored or operated incorrectly. There is a tremendous amount of research and engineering effort going into making batteries safer but are technological advancements being rolled out quickly enough?
System design for PV-driven hybrid EV charging stations
Researchers in India have simulated a 4 kW solar power-based hybrid electric vehicle charging station using a three-stage charging strategy and found that the station is capable of charging 10–12 EVs with 48 V 30 Ah lithium-ion batteries.
