On December 16, Guoxia Technology Co., Ltd. (02655.HK), a Wuxi-based developer of renewable energy and energy storage solutions, officially listed on the Main Board of the Hong Kong Stock Exchange. The successful debut marks a pivotal milestone in the company’s development, reflecting its rapid revenue growth, technology-driven differentiation, and early integration of artificial intelligence across both cloud-based platforms and physical energy storage assets.
Operating under a dual-brand strategy, “Guoxia Technology” in China and “HANCHU ESS” in international markets, the company positions itself for accelerated global expansion and broader access to international capital. This approach underscores Guoxia’s ambition to evolve into a leading global AI-enabled energy storage solutions provider, bridging intelligent software with large-scale physical infrastructure.
Company Background and Origins
Founded in 2019 by three alumni of Jiangnan University, Board Chair Feng Lizheng, CEO Zhang Xi, and Executive President Liu Ziye, Guoxia Technology demonstrates the synergy between academic expertise and industrial entrepreneurship. Leveraging mechanical engineering, process automation, and industrial systems backgrounds, the founders identified early opportunities in China’s emerging energy storage sector.
An initial CNY 5 million angel investment from a fellow alumnus provided the foundation for early R&D and operational scaling. By embedding academic rigour into industrial execution, Guoxia accelerated technology validation while establishing disciplined governance and robust operations.
This strategy translated into financial performance. Revenue grew from CNY 142 million in 2022 to CNY 1.03 billion in 2024, while H1 2025 revenue reached CNY 691 million, representing 663% year-on-year growth. Large-scale storage systems remain the primary growth engine, while international expansion and diversified customer segments enhance long-term resilience.
