VICTORIA, Australia - eTradeWire -- In Search of a Superior Battery - Go Sail Cargo Moves Toward Strategic Partnership with Digital Battery Ltd.

Queensland, Australia —  January 26^th 2026 - Go Sail Cargo (GSC) and Digital Battery Ltd. (DBL) have announced that they are exploring a strategic partnership to integrate next-generation hybrid battery systems into GSC's new fleet of zero-emission sailing cargo vessels.

Early engineering and design collaboration is already underway, with both companies working to incorporate DBL's software-defined battery architecture into GSC's innovative electric clipper range. A custom installation, adjacent to the keel, is being evaluated to optimize safety, stability, and performance while maximizing cargo capacity.

"We found it! Digital Battery Ltd has addressed every one of our demanding requirements," said Derek Ellard, founder of Go Sail Cargo. "At Go Sail Cargo, our mission is to create a range of practicable, scalable shipping solutions powered by the infinite energy of wind and sun. With the enhanced performance lifecycle, superior safety and reduced maintenance of DBL's batteries, custom stacked way down over the keels, the final piece in the maritime jigsaw is in place. By committing to absolute zero-carbon operation we cut out the diesel middleman – and all life on Earth benefits."

The collaboration is designed to enable fully net-zero carbon vessel operations by integrating wind propulsion, propeller regeneration, solar power, and high-performance energy storage. By removing fossil-fuel main engines, vessels can achieve dramatically lower operating costs and significantly reduced maintenance requirements.

Diesel generators are retained solely for emergency backup during the transition period, until compact onboard hydrogen production systems become available. These systems will operate when renewable power generation exceeds onboard demand and battery capacity is fully charged, converting surplus energy into hydrogen that functions as a long-duration energy reserve—effectively extending the vessel's battery system.

Digital Battery's hybrid architecture delivers superior safety, long lifecycle, and high-power performance compared to traditional lithium systems, while intelligent software control continuously optimizes operation in the harsh marine environment. This combination is expected to accelerate return on investment (ROI) for vessel operators through the elimination of fuel spend, minimized downtime, and extended asset life.

"We're excited to continue discussions with Go Sail Cargo to help redefine what's possible in sustainable maritime transport," said Tim Houchin, Co-Founder of Digital Battery Ltd. "Our batteries are purpose-built for reliability and performance in demanding environments such as the open ocean. When combined with Go Sail Cargo's innovative designs, we're helping to unlock a new class of ships that are safer, greener, and commercially compelling."

• Validate performance, safety, and economics at sea,
• Progress toward broader fleet deployment through future definitive partnership and supply agreements.

This potential alliance positions Go Sail Cargo at the forefront of the rapidly expanding zero carbon freight sector while providing Digital Battery with a flagship maritime deployment in one of the world's most technically demanding applications.

Together, the companies aim to demonstrate that zero-emission ocean freight can be not only environmentally transformative, but also economically superior.
