Aquaspira Delivers Innovative Firewater Containment for BESS, Adopted by UK’s 400MW Hams Hall Facility

Aquaspira UK

Overview

Aquaspira has introduced an innovative firewater storage solution for Battery Energy Storage System (BESS) sites, addressing environmental concerns and stricter regulatory requirements. Their pollution containment tank system, featuring a three-leg tank configuration, reduces the overall footprint by approximately 30% and minimizes leakage points through simplified design. This solution was adopted for the 400 MW / 1.4 GWh Hams Hall BESS facility in the UK, one of Europe’s largest, establishing a new standard for fire safety infrastructure in the scaling BESS sector.

Key Findings

Aquaspira has launched an innovative solution for firewater containment specifically designed for Battery Energy Storage System (BESS) sites, directly addressing growing environmental concerns and increasingly stringent regulatory requirements. Their proprietary pollution containment tank system, uniquely configured with a three-leg tank design, successfully reduces the overall site footprint by approximately 30%. Furthermore, its simplified design minimizes potential leakage points, enhancing the system’s overall reliability and safety. This groundbreaking solution has been adopted by the 400 MW / 1.4 GWh Hams Hall BESS facility in the UK, one of Europe’s largest, thereby setting a new standard for fire safety infrastructure within the rapidly expanding BESS sector.

Technical Details

Aquaspira’s firewater containment solution is engineered to safely store and manage water contaminated with pollutants that may arise during a BESS fire. BESS fires can release toxic gases and contaminants due to thermal runaway, and the water used for suppression efforts risks carrying these substances into the environment. Aquaspira’s system effectively mitigates this risk:

• Three-Leg Tank Configuration: This unique design achieves more efficient space utilization compared to traditional single or multi-tank arrangements, reducing the installation footprint by about 30%. This is critical for BESS deployments in space-constrained locations.
• Simplified Design: By reducing the number of components and minimizing connections, the design significantly lowers the risk of leakage, which is paramount for effective pollutant containment.
• Pollution Containment Capability: Reliably collects and stores potentially acidic water, heavy metals, and other hazardous chemicals released during a BESS fire, preventing their discharge into the environment.
• Adoption at Hams Hall BESS: Its deployment at the Hams Hall facility in the UK (400 MW / 1.4 GWh), one of Europe’s largest and most advanced BESS sites, serves as strong evidence of the solution’s practicality and high reliability.

This system is a crucial infrastructure component for reducing environmental risks in BESS operations and assisting regulatory compliance.

Background & Industry Context

The global deployment of BESS is accelerating to facilitate the integration of renewable energy, but this growth is accompanied by escalating concerns regarding fire safety and environmental pollution. Many countries are tightening BESS fire safety regulations, and specifically, the management of firewater (containment of contaminated fire suppression water) has become an indispensable requirement for environmental protection and public health. Aquaspira’s solution directly addresses these industry-wide needs, supporting BESS projects in obtaining permits and ensuring safe operations.

Strategic Significance & Outlook

Aquaspira’s innovative firewater containment solution is poised to elevate safety and environmental standards in BESS design and operation. The success at a large-scale facility like Hams Hall is likely to serve as a benchmark for other BESS developers and operators, encouraging the adoption of similar technologies. This will enable BESS deployments to proceed more safely and sustainably, playing an indispensable role in the renewable energy transition and strengthening grid resilience. As BESS scales up and is deployed closer to populated areas, the importance of such comprehensive safety and environmental solutions will only continue to grow.
