Building a new type of power system with new energy as the main body is an important part of ensuring energy security and achieving sustainable development. In Dalian, Liaoning, the independently developed globally leading "all vanadium flow battery energy storage" technology has taken root, not only adding a huge "power bank" to the city, but also providing new impetus for the transformation of the local industrial and economic structure.
All vanadium liquid flow energy storage provides a green "power bank" for cities
Entering the Rongke Energy Storage All Vanadium Flow Battery Production Base in Dalian, Liaoning, the first thing you see is rows of containers ready to be shipped. These containers that are about to be shipped to various places are not ordinary shipping containers, but rather all vanadium flow battery modules. One is a battery stack, and the other is a vanadium electrolyte. Two containers are stacked up and down to form a green energy storage station, which can store 3000 kWh of wind and solar power at once. If calculated based on a household's monthly electricity consumption of 200 kWh, it can provide a household with 15 months of electricity consumption. Unlike common lithium-ion batteries, lead-acid batteries, etc., all vanadium flow batteries not only have high safety, long cycle life, but also are more environmentally friendly.
These containerized "power banks" can also be connected to each other, forming larger urban energy storage power stations. At the Dalian Flow Battery Energy Storage and Peak shaving Power Station, the reporter saw larger containers neatly stacked, with over 700 vanadium liquid tanks arranged neatly on an area the size of two football fields on the first floor. The second floor is a more integrated vanadium battery pack. The first national level large-scale chemical energy storage demonstration project approved by the National Energy Administration was connected to the grid in May last year and achieved full load charging and discharging by the end of October, with a maximum storage capacity of 400000 kilowatt hours. Based on the daily average electricity consumption of 2 kWh per resident in our country, this power station can meet the daily electricity demand of 200000 residents. With so many devices, at least three people are needed to complete the monitoring and operation of the entire energy storage plant.
