CNTE at KEY ENERGY 2026: Showcases STAR H‑PLUS Outdoor Liquid‑Cooled Energy Storage System

RIMINI, Italy, March 4, 2026 /PRNewswire/ -- Contemporary Nebula Technology Energy (CNTE), a global energy storage provider invested by CATL, unveiled its latest innovation—the STAR H‑PLUS Outdoor Liquid‑Cooled All-in-One Energy Storage System—at KEY ENERGY 2026 (Booth B7-362). This flagship product underscores CNTE's commitment to performance, safety, and lifecycle value in outdoor energy storage.

Smart, Efficient, and Easy to Deploy

The STAR H‑PLUS system (125 kW / 254 kWh) integrates intelligent thermal control, high energy density, and simplified operation to meet diverse global energy storage needs. With an energy density of 83.6 kWh/m³, up to 14 units (3.56 MWh) fit in a 40‑ft container, reducing transport and storage costs.

Its maintenance-friendly design streamlines field service: one-button start/stop enables fast commissioning, a lightweight configuration tool replaces traditional software, and rear-access service plus quick connectors cut maintenance time. The liquid cooling system supports automatic coolant replenishment, and the upgraded combustible gas detector is maintenance-free for 10 years, lowering operational costs.

Quiet, Intelligent, Reliable

STAR H‑PLUS operates at ~65 dB under full load, suitable for noise-sensitive sites. AI-driven adaptive temperature control keeps cell variance ≤3 °C, enhancing longevity and stability in extreme conditions.

High Performance and Fast Response

Powered by CATL LFP 306 Ah cells with ≥10,000 cycle life, STAR H‑PLUS delivers >88% round-trip efficiency. Optional 314 Ah cells support specific project needs. The system allows parallel operation of up to 10 units (2.54 MWh) and rapid frequency regulation (<200 ms response). Paired with an STS transfer cabinet, it ensures seamless switching between grid-tied and off-grid modes for uninterrupted power.

Global Certifications and Readiness

Meeting grid requirements in 45 countries and holding IEC and UN38.3 certifications, STAR H‑PLUS is ready for reliable international deployment.
