News from China Energy Storage Network: On April 17, the State Council Information Office held a press conference themed "Getting Off to a Good Start in the 15th Five-Year Plan", which clearly stated that China will vigorously advance energy technology innovation and launch key R&D campaigns in long-duration energy storage, controlled nuclear fusion and other major technologies. This strategic arrangement sends a strong signal: the strategic value of long-duration energy storage (LDES) is rapidly emerging.
According to the National Energy Administration, by 2025, China’s cumulative installed capacity of wind and solar power reached 1.84 billion kW, accounting for 47.3% of the total power mix—surpassing thermal power for the first time in history. China’s energy production structure has entered a new era led by new energy and green power.
However, wind and solar power are highly weather-dependent, with obvious intermittency and volatility, leading to growing curtailment pressure. Meanwhile, emerging super loads represented by AI Data Centers (AIDC) face a structural mismatch between exponentially growing computing demand and linearly growing power supply. Against this backdrop, long-duration energy storage—with its comprehensive advantages of being green, economical and secure—has become the key to breaking through these bottlenecks.
Native Long-Duration Design: Fusion Energy Storage Reconstructs Power Value Logic
Keenly capturing this market demand, Fusion Energy Storage addresses the limitations of short-duration storage (1–2 hours), which cannot support cross-timeframe regulation or fully solve wind and solar curtailment.
Starting from system-level design, the company has reconstructed its electrical, structural and thermal management architectures, and developed custom ultra-large-capacity cells of 3000Ah+ dedicated for long-duration scenarios, with energy efficiency exceeding 96.5%.
Based on these innovations, Fusion Energy Storage launched its next‑generation large‑capacity native long‑duration storage product:Ronghe · Yinglong Max 8MWh+ Energy Storage Container
It supports 8–16 hours of continuous charging/discharging, fully covering household and industrial power demand from sunset to sunrise. It enables day‑ahead energy shifting and delivers effective regulation for high‑penetration wind and solar renewable energy systems.
In addition to long discharge duration, the Yinglong Max system offers an extra-long calendar life of more than 15 years, truly achieving asset lifetime matching between power generation and energy storage sides.
Backed by Fusion Energy Storage’s massive database of over 10 million cells, combined with digital twin and AI modeling algorithms, the system enables multi‑dimensional online monitoring and real-time early warning for every single cell, building a solid safety foundation for long‑duration operation.
String Architecture: Breaking the "Circulation Dilemma" in Parallel Expansion
Traditional centralized architectures easily cause inter-cluster circulation and the "bucket effect". These issues become more severe in long‑duration storage systems as capacity and operating hours rise.
To solve this, the Yinglong Max adopts an innovative modular string architecture, achieving independent precise control at the cluster level and physical isolation on the DC side. It effectively suppresses circulation and the bucket effect, improves operating efficiency, and greatly enhances flexibility for system modification and O&M. The system’s lifecycle power throughput increases by more than 5%.
Furthermore, the Yinglong Max integrates an AI‑enabled predictive thermal management strategy, keeping the system in optimal condition and reducing auxiliary power consumption by more than 6%.
Driven by core technologies and committed to ecological collaboration, Fusion Energy Storage rides the wave of energy technology innovation in the 15th Five-Year Plan. The company will continue to embrace an open and win‑win mindset, deepen cutting-edge applications such as direct green power connection and long‑duration energy storage, actively empower the new power system, and jointly build a green future.
