This month we are proud to feature AYK Energy as our Member of the Month! Founded in 2018 by Chris Kruger with the goal of producing a low-cost battery that offers superior performance and safety and exceeds class and industry standards. Already a pioneer in the marine battery sector having developed the very first marine type approved battery in 2013, Chris and his team have continued to drive development and safety in the marine battery industry while drawing on 15 years industry experience.
From Enabler to Market Leader
AYK Energy is a fast-growing maritime battery company positioning itself as a key enabler of maritime electrification. While the company has historically taken a low-profile approach, it is now making a strategic pivot toward more active market engagement with a clear ambition: to become a market leader in marine battery systems and challenge established players.
AYK Energy’s focus is firmly on supplying battery systems and integrated solutions that make electrification practical, scalable, and operationally viable for shipowners. Rather than seeing itself as just a component supplier, the company positions its technology as an essential building block for the next generation of electric and hybrid vessels.
Proven at Scale: World-Leading Marine Battery Projects
AYK Energy is supporting some of the world’s most significant marine electrification projects across multiple vessel segments. The company is powering the world’s first fully electric intercontinental ferry route for Baleària, with twin 13.8 MWh battery-electric fast ferries operating between Spain and Morocco. It has also installed two 11.8 MWh Orion+ systems for Brittany Ferries on Guillaume de Normandie and Saint-Malo, marking major battery installations in the RoPax segment. In addition, AYK delivered the world’s largest RoPax battery retrofit for Wasaline, increasing Aurora Botnia’s capacity from 2.2 MWh to 12.6 MWh.
Beyond ferries, the company supplied batteries for the first fully electric, battery-capable self-unloading bulk carrier for CSL and is delivering a 6 MWh system for the world’s first battery-methanol hybrid tug for Svitzer. AYK has also secured a contract to supply a 16 MWh Pisces+ battery for Germany’s next-generation polar research vessel Polarstern 2, via Wärtsilä for the Alfred Wegener Institute. Upon delivery, this will be the largest battery ever installed on an ice-class vessel.

Built on Certification and Manufacturing Excellence
The company holds approvals from all major international classification societies, including DNV, ABS, RINA, LR and BV. In addition, AYK Energy has obtained enhanced system-level maritime cyber security certification from DNV under Cyber Security Profile Level 1 and IACS UR E27, enabling secure remote monitoring, real-time commissioning support and protected cloud-based data management for its battery systems.
This capability is reinforced by the company’s 5,000 sqm automated manufacturing facility in Zhuhai, China, opened in 2023 with an annual production capacity of 300 MWh and expansion potential to 1 GWh. Together, global approvals and scalable production position AYK Energy to meet the demanding safety and quality standards of leading shipowners and shipbuilders worldwide.
Solving the Real Bottleneck: Shore-Side Infrastructure
In an exclusive interview with AYK Energy’s Founder, Chris Kruger, he explains that the single biggest barrier to widespread maritime electrification is not the batteries themselves, but the lack of shore-side infrastructure. Many ports today are unable to deliver the high-power, fast-charging capabilities required to recharge vessels quickly enough to support full electric operations.
This limitation directly impacts vessel design and operational planning. Without reliable access to rapid charging, shipowners struggle to achieve the turnaround times needed for commercial viability, especially on tight schedules. The company views this infrastructure gap as the primary constraint holding back full electrification more so than battery chemistry or onboard system performance.
Flagship Innovation: The Swappable Marine Battery Container
To address these constraints, AYK Energy is developing a flagship product that rethinks how energy is delivered to ships: a type-approved, swappable marine battery container. Designed to fit into a standard cargo hold, the container can be handled using existing port logistics, making it compatible with today’s infrastructure.
The concept enables vessels to swap battery packs instead of waiting to recharge, dramatically reducing downtime and removing dependence on high-power shore connections. In addition to rapid energy replenishment, the containerized approach also simplifies permanent installations, offering shipowners flexibility as their operational needs evolve.
This solution reflects the company’s practical mindset working around real-world constraints rather than waiting for ports to fully adapt.

Industry Perspective and Future Outlook
AYK Energy sees batteries as the primary propulsion solution for maritime decarbonization for the foreseeable future. While alternative energy concepts may emerge over time, the company believes that no clean, safe, and easily deployable alternative is currently ready to displace batteries at scale. Until such solutions materialize, batteries will remain central to both hybrid and fully electric vessel designs.
From the company’s perspective, innovation must focus not only on battery performance but on system-level solutions that address charging, logistics, and operational flexibility. By combining battery technology with novel deployment models such as swapping, the company aims to unlock faster adoption across multiple vessel segments.
Looking Ahead
With its strategic pivot toward greater market visibility, AYK Energy is entering a new phase of growth. By focusing on infrastructure-aware solutions and challenging conventional assumptions about charging and installation, the company is positioning itself at the forefront of maritime electrification.
As the industry continues to grapple with infrastructure limitations and the pace of the energy transition, the company’s approach highlights an important truth: accelerating electrification is not just about better batteries it’s about smarter ways to use them.
About the Maritime Battery Forum
The Maritime Battery Forum was founded with the aim of promoting new and efficient energy storage technologies in the maritime industry. With over 90 members across 3 continents, the MBF works to disseminate information, facilitate discussion, and accelerate the journey towards a zero-emission maritime future.
