China has connected to the grid a 100 MW hybrid energy storage facility that integrates supercapacitors and lithium-ion batteries
Touted as the world’s largest supercapacitor-based installation, the facility combines a 58 MW/30-second supercapacitor array with 42 MW/42 MWh of lithium-ion battery storage, spanning a footprint of approximately 16,800 square meters.
Supercapacitors provide ultrafast response times – specified at 0.001 seconds – and maintain over 85% capacity at –40°C, significantly outperforming lithium-ion batteries in extreme cold. By offloading rapid-response tasks to the supercapacitor, the system is expected to extend battery lifespan and reduce lifecycle costs by around 30%
I love when people point to China and their “renewables” and batteries as an example, and just ignore the fact that they’re building dozens of new coal power plants every year, along with nuclear plants which the people pushing these articles refuse to even consider.
Nuclear plants are a good thing overall.
Pal bad tho.
