The world has now realized its first-ever grid-scale semi-solid energy storage system in China. A 100MW/200MWh plant makes up the first phase of the Longquan Energy Storage Project. As an advanced energy storage system in its own right, it kind of proves that semi-solid energy storage technology is usable in grid projects.
Semi-solid energy storage is another hybrid technology battery wherein the solid-state battery-like structural stability comes with the flexibility of the liquid-based traditional lithium battery. This new technology enhances safety while improving lifespan and energy density.
Higher thermal stability: very low chance of overheating and high safety.
Long lifecycle: costs less since it lasts longer.
More energy density: more powerful than traditional lithium-ion batteries.
Lesser chance of leakage and fire: safer and environmental-friendly.
Planned Capacity: 200 MW/400 MWh
Operational Capacity: 100 MW/200 MWh
Annual Discharge Capacity: 60 million kWh
Importance: It is the largest energy storage power station of Lishui, China, and is of great importance!
The enhanced status of this project not only means that semi-solid energy storage technology has bright prospects but also opens new inspirations for the future storage of energy.
The Longquan plant comprises WeLion's 280Ah lithium iron phosphate (LFP) hybrid batteries at its heart. Half-solid in construction and having an energy density of over 165Wh/kg, the batteries sustain more than 6,000 charging-discharging cycles. They have an operating temperature range from -20°C to 60°C, thus offering excellent operational capability in snow, ice, and hot summer conditions.
Kehua Technology, the No. 1 power solution company in China, supplied the power conversion system for the Longquan project. To be precise, they installed the following equipment:
25 customized 5MW sleds: Every sled housed 4 state-of-the-art 1.25MW converters.
Connected to a 5000kVA transformer, So that power can be injected smoothly into the 35kV AC Grid.
Such units ensure smooth power conversion and grid compatibility and pave the way toward energy dispatch with much ease.
An instance of a world-class semi-solid energy storage system is aptly given by the Longquan Energy Storage Project. As nations are seeking cleaner and reliable energy infrastructures, semi-solid energy storage offers a scalable and safe alternative.
Decentralized power supply enhancement
Grid flexibility and resilience improvement
Reduced dependency on fossil fuels
Boost to China's energy storage leadership
The world increasingly requires stable and sustainable energy solutions. Semi-solid storage intermediates between the widely recognizable points of Lithium-Ion Battery technology and a new modern solid state technology. Given that these two technologies unite their successful attributes, hence, it will most probably become the "pillar" supporting new energy storage infrastructure, especially in grid-scale applications.
