How Long-Duration Energy Storage (LDES) Is Reshaping the Grid


How Long-Duration Energy Storage (LDES) Is Reshaping the Grid

On January 14, 2020, China launched its first large-scale indoor lithium-ion energy storage power station – the Fujian Jinjiang Energy Storage Power Station Pilot Project Phase I (30MW/108MWh). Just one day later, it was successfully connected to the grid. This marked a key milestone in the country’s journey toward advanced energy solutions. At the heart of this progress is Long-Duration Energy Storage (LDES). With the ability to store energy for hours or even days, LDES is no longer just a technical term – it’s becoming the backbone of a more stable, flexible power grid.

This project is only the beginning. As investments grow and new phases roll out, one question remains: how far can LDES go in reshaping our energy future?

Why LDES Matters Now More Than Ever

From Peak Demand To Grid Stability

Modern electricity use is no longer predictable. As cities grow and industries run 24/7, power demand rises fast – especially in the evening when solar energy fades. Renewable sources like wind and solar are clean, but they don’t always align with usage. This is where Long-Duration Energy Storage (LDES) steps in.

LDES stores excess energy during low-demand or high-generation periods. It then releases it when the grid needs support – during peak hours or unexpected outages. This helps stabilize the grid, reduce blackouts, and ease pressure on power plants.

The Role Of Long-Duration Energy Storage (LDES)

LDES is different from short-term storage. It doesn’t just buffer the grid for minutes. It stores energy for hours, and even days, making it a vital part of a clean energy future. With LDES, renewable energy becomes more reliable. We can use daytime solar energy at night or save wind energy for calm days.

LDES also reduces our need for coal or gas backup. By shifting clean energy to when it’s needed, it lowers carbon emissions and helps utilities meet their sustainability targets. It also cuts energy costs over time.

Global Momentum For LDES

Worldwide, countries are accelerating their LDES investments.

  • In the UK, liquid-air storage systems are under trial for multi-day power support.
  • In the U.S., California is scaling up pumped hydro and compressed air storage.
  • In Australia, iron-flow battery systems are powering remote grids.

These projects signal one thing: Long-Duration Energy Storage (LDES) is not just a trend-it’s the future.

STAR-H: The Next Generation of C&I Long-Duration Energy Storage

Engineered for the Outdoors

STAR-H is CNTE’s advanced Long-Duration Energy Storage (LDES) solution for commercial and industrial (C&I) applications. Housed in a rugged outdoor liquid-cooled cabinet with an IP65 rating, STAR-H is built to endure challenging conditions-resisting dust, rain, and extreme temperatures. It’s the perfect fit for remote industrial zones, solar farms, and outdoor substations.

Precision Cooling, Extended Life

At the heart of STAR-H is an efficient liquid cooling system that keeps internal temperature fluctuations under 3°C-even during heavy loads. This precise thermal control reduces wear and tear on battery components, significantly extending system lifespan and performance reliability.

Scalable, Plug-and-Play Deployment

STAR-H adapts to projects of any size:

  • Single units offer capacity from 206 kWh up to 4 MWh
  • Up to 10 cabinets can operate in parallel with zero-gap connection
  • Plug-and-play design allows for rapid setup and smooth integration
  • Whether for a compact site or a large-scale installation, STAR-H scales effortlessly.

Built-In Safety: Quadruple Protection

Safety is a core pillar of STAR-H, with four integrated protection systems:

  • Smoke and temperature sensors
  • Aerosol-based fire suppression
  • Combustible gas detection
  • Explosion relief valves

These features work together to ensure safe and stable operation in any scenario.

Smart EMS and Cloud-Based Monitoring

STAR-H comes equipped with an intelligent Energy Management System (EMS) that actively optimizes performance and monitors over 64 real-time data points. Combined with CNTE’s cloud platform, users gain full remote access for:

  • System alerts and fault prevention

With STAR-H, you get more than storage-you gain intelligence, efficiency, and peace of mind.

STAR-H Deep Dive: Uncompromising Safety And Reliability

Quadruple Protection Design

Safety is not optional – it is essential. STAR-H uses a four-layer protection system. It includes thermal detectors, smoke alarms, aerosol fire suppression, and gas sensors. An explosion relief valve adds an extra layer of defense. This makes STAR-H one of the safest Long-Duration Energy Storage (LDES) systems on the market.

CATL LFP Cells For Long Life

We use original CATL lithium iron phosphate (LFP) battery packs. These cells offer high safety and long lifespan. STAR-H delivers up to 28,000 cycles, reducing replacement costs and improving stability. It ensures consistent performance, even after years of use.

All-Weather Resilience

STAR-H performs well in harsh conditions. It operates in temperatures from -25°C to 55°C. Even in extreme heat, it maintains stable output. The system is IP65-rated, which means it resists dust, rain, and outdoor wear. It’s built for real-world deployment.

Intelligence At The Core: Smart EMS And Cloud-Based Monitoring

Intelligent EMS Optimization

Every STAR-H unit includes an intelligent energy management system (EMS). It tracks system behavior in real time. It makes automatic adjustments to optimize charging and discharging. This reduces stress on the batteries and increases efficiency. For Long-Duration Energy Storage (LDES), intelligent control is vital.
