Clou, a BNEF Tier 1 energy storage system provider, showcased its latest innovations in energy storage at Solar & Storage Live UK 2025 in Birmingham. The centerpiece was the Aqua-C3.0 Pro liquid-cooled energy storage system, debuting in Europe for the first time, alongside multiple integrated energy storage solutions for commercial and industrial applications.
Growth in the UK Energy Storage Market
The UK energy storage sector is rapidly expanding due to clear policy frameworks, established electricity market mechanisms, and diverse revenue opportunities. While large-scale utility projects continue to rise, demand for commercial and industrial (C&I) energy storage is accelerating. Clou’s European debut addresses this growing need with advanced, large-capacity energy solutions.
Operational Details: Aqua-C3.0 Pro Features
The Aqua-C3.0 Pro boasts over 600 Ah per cell and a total capacity of 6.88 MWh in a single enclosure. Key advancements include:
-
Direct liquid cooling to cells for higher efficiency and safety.
-
Patented Smart Scales and SiC String PCS balancing technology, achieving 92.3% RTE and boosting lifetime energy production by 4%.
-
CTR architecture for separated thermal and electrical paths and directional ventilation.
-
ThermoFlux 2.0 explosion-proof active ventilation system, developed with Midea Group, offering early warning, fire suppression, and explosion protection.
-
Simplified O&M, with reduced components, self-powered auxiliary systems, and remote monitoring to cut operational costs.
Economic Impact: Efficiency and Cost Reduction
By improving energy efficiency, reducing total cost of ownership by 10.63%, and simplifying maintenance, Clou’s Aqua-C3.0 Pro provides operators with lower operational expenses and longer system lifetimes. The modular 20-foot container design also enhances transport convenience and rapid deployment.
Strategic Significance: European Market Expansion
Clou’s showcase reflects its commitment to supporting Europe’s energy transition. Drawing on 30 years of electricity sector experience and successful global projects—from the U.S. to South America—Clou is integrating products into local electricity markets while leveraging local teams and service networks for efficient O&M support.
