Battery storage

Figures from the Philippines Department of Energy (DOE) show that 1.98 GW of renewable energy projects are under construction on the archipelago of Visayas, with solar accounting for more than one-third of the capacity.

Flexbase plans to build a 500 MW redox flow storage project in Laufenburg in early 2025.

JSW Neo Energy and Reliance Power have secured 500 MW each in Solar Energy Corp. of India’s (SECI) latest tender to set up 1 GW/2 GWh of standalone battery energy storage projects.

The Greek government decided to auction 100 MW less capacity than initially sought and to offer more money to the awarded projects than expected.

By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.

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.

The Chilean solar market is booming but as curtailment grows, a hybrid approach to generation is gaining ground. Storage project announcements are coming thick and fast as co-location with wind turbines offers cost efficiency and a smoother generation profile. Meanwhile, new capacity mechanism rules could take Chile one step closer to runaway battery growth.

China’s Huawei has built a 400 MW/1.3 GWh solar-plus-storage off-grid facility in Red Sea New City, Saudi Arabia.

Renewable Energy Expo India (REI) returns to Greater Noida at the start of October, for what will be its 17th edition. For the second year running, The Battery Show India will run concurrently with REI. pv magazine had the chance to catch up with Julian Thomas, Senior Project Director at show organizer Informa Markets, to discuss why electric vehicles and energy storage are now the key to India’s energy transition.

This year’s edition of the China International Energy Storage Expo (EESA EXPO) has underlined the latest energy density achievements in the battery energy storage space on both cell and system levels. Meanwhile, the sheer number of commercial and industrial (C&I) systems on display spoke of growing demand in this market segment. Alternative lithium-ion battery chemistries were not easy to find.
