AYK Energy is set to launch the world’s first swappable containerized marine battery system, the Cosmos, at the SMM trade fair in Hamburg. Designed to eliminate the need for complex, costly dedicated battery rooms, the system offers flexible deployment options ranging from rapid port swaps to permanent installations. Featuring eight independent safety levels, IP67 protection, and an A60 fire rating, the innovative solution aims to accelerate maritime decarbonization across commercial fleets.
Andorra la Vella, Andorra | August 21, 2026 – Leading marine battery manufacturer AYK Energy is set to shake up the commercial shipping sector at the SMM trade fair in Hamburg by unveiling the world’s first swappable containerized marine battery system. Dubbed the AYK Cosmos Marine Battery Container, this breakthrough technology is engineered to tear down the cost, design, and engineering barriers that have traditionally complicated shipboard electrification.
Even prior to its official debut, AYK confirmed it is already securing commercial orders for the Cosmos system. The technology has successfully completed the rigorous New Technology Qualification (TQ) stage, a vital framework proving sufficient technical maturity, while moving rapidly through full class approval.
Eliminating the Dedicated Battery Room Dilemma
Traditional marine battery installations often demand intricate engineering and high capital expenditures, particularly regarding specialized, dedicated battery rooms. According to Chris Kruger, founder of AYK Energy, the Cosmos container completely redefines how energy storage can be deployed and managed onboard vessels.
“We are very proud to bring this innovation to the global marine market,” said Kruger. “A vast amount of engineering time and investment has gone into this. The AYK Cosmos Marine Battery Container will simplify installation, reduce engineering complexity, lower project costs and speed up implementation. The system also removes the need for a dedicated battery room which can be a highly complex engineering job and significant cost.”
Kruger emphasized that the system’s inherent flexibility allows units to be swapped dynamically between voyages or permanently integrated, depending on the operational profile of the ship.
Unmatched Operational Flexibility and Shore-Side Synergy
The design of the Cosmos container introduces plug-and-play adaptability to commercial fleets, unlocking new operational use cases:
- Shore-Side Charging & Swapping: Containers can be stacked onshore, charged off-site with green energy, and rapidly loaded onto vessels at port.
- Voyage Tailoring: Operators can scale energy capacity dynamically, loading dozens of containers at a time, to easily fulfill short-sea fully electric transit requirements in the EU and navigate tightening emissions regulations like EU ETS.
- In-Port Hotel Power: The units can be utilized to supply temporary, zero-emission hotel-load power while ships are berthed, sharply lowering port-side emissions and noise pollution.
- Permanent or Hybrid Setup: While ideal for quick-swap logistics, the system can also be permanently installed for dedicated hybrid or fully electric vessels.
Eight Independent Levels of Safety
Designed as one of the most advanced energy storage systems ever engineered for maritime applications, the Cosmos container prioritizes redundancy and asset safety. It integrates eight independent levels of safety, featuring IP67 protection and an A60 fire rating.
While primarily targeting the high-frequency ferry, RoPax, and passenger vessel segments, the system is fully adaptable to tugboats, feeder vessels, hybrid commercial craft, and general workboats.
“We firmly believe our technology will remove the barriers to electrification, make battery technology easier to adopt, and as a result accelerate maritime decarbonisation,” added Kruger. “The system we have developed combines safety, flexibility and cost-effectiveness; which we believe are the three pillars that will support the accelerated electrification of the sector.”
AYK Energy maintains a strong history of market firsts, including pioneering safer Lithium Iron Phosphate (LFP) cell chemistry in the marine sector and securing the industry’s very first DNV marine type-approval for LFP technology.
