With this move, Longi reports that it is evolving from a photovoltaics company into a supplier of integrated energy solutions for solar, energy storage and hydrogen. Dennis She, Vice President at Longi, has now unveiled the company’s “Stability Triangle” energy concept for the first time. This concept is based on the combination of solar energy, energy storage and hydrogen.
“Solar energy is the producer of clean energy, energy storage is the stabiliser of the power system and hydrogen is the regulator that balances everything,” explained She. The synergy of these three elements, he said, is intended to enable a resilient and affordable net zero energy system.
Longi points to technological advances in photovoltaics and hydrogen. The company’s HIBC cells achieve an efficiency of 27.81 percent. Its alkaline electrolysers are already reaching double-digit megawatt outputs. By entering the energy storage sector, Longi aims to cover the entire value chain from solar and storage through to hydrogen.
Focus on safety and reliability
Longi emphasises that energy storage is a central component of renewable energy systems. She sees the sector shifting from policy-driven to market-driven growth. He said: “Safety, reliability and stability are the benchmarks for evaluating energy storage solutions – and at the same time, they are the foundation for long-term market and customer confidence.”
To deliver on its promise of “ultimate safety,” Longi is working with PotisEdge. This storage safety specialist relies on a technical architecture that is built around intrinsic safety, active defence and intelligent early warning. The company cites a safety record of “zero thermal runaways” across more than 12 gigawatt hours of energy storage systems over the past ten years. This expertise is intended to provide a robust technical foundation for Longi’s energy storage solutions.
Innovation centre for solar and storage technology
Longi has now announced the establishment of its first innovation centre for solar and storage technology (Centre of Excellence, CoE) in Europe. The centre, based in London, will bring together project consulting, technical training, operations and maintenance, as well as spare parts services. The company plans to launch its energy storage solution initially in the UK, Germany, Italy and Spain.
