Archean Chemical's investee Offgrid Energy Labs (18.14% stake, USD 12M invested) inaugurated its first Zinc Bromide battery (ZincGel) 10 MWh pilot manufacturing facility at Hook, Hampshire, UK on July 7, 2026. The plant marks the move from lab innovation to commercial pilot-scale production of long-duration energy storage batteries. The technology synergises with Archean's Bromine business and lays the foundation for a planned giga-factory in India. No additional financial commitment from Archean.
Positive strategic update: investment advances to pilot stage with no extra cash outflow. Long-term value hinges on scale-up and giga-factory execution.
