CALB (China Aviation Lithium Battery) has deployed its 1.2MWh marine battery system aboard Saudi Aramco's Karan 8 hybrid vessel, marking a key milestone in maritime decarbonization. This successful sea trial represents a significant step in advancing hybrid offshore support vessel (OSV) technology. Notably, CALB has become the first Chinese battery manufacturer to achieve both DNV and ABS certifications for marine systems, highlighting its leadership in marine energy solutions.

The Karan 8, equipped with CALB's advanced battery technology, is set to begin operations in the Persian Gulf in Q2 2025. It will support low-carbon maritime activities such as oil exploration, crew transfers, and platform supply transport. The hybrid oil-electric system on the vessel is expected to reduce fuel consumption and carbon emissions by 30% compared to conventional vessels.

This project underscores CALB’s ability to deliver rapid, high-performance energy storage solutions. The company completed the entire project lifecycle—from design to Factory Acceptance Testing (FAT) in just 60 days—demonstrating its technical expertise and commitment to accelerating sustainable shipping solutions.

As the maritime industry shifts toward decarbonization, CALB is well-positioned to expand its footprint in global marine applications. Its scalable, innovative solutions align with international environmental goals, contributing to the cleaner, more sustainable future of the maritime sector.
