eCap Marine delivers hydrogen and containerised battery power systems for sustainable shipping. From engineering and system integration to class certification, the company supports shipowners and shipyards in implementing zero-emission propulsion solutions. With projects ranging from battery-electric systems to multi-megawatt hydrogen power generation, eCap Marine combines engineering, system integration and class certification under one roof.
At SMM 2026, the company will present its containerised battery systems and hydrogen solutions, demonstrating how scalable energy systems can support the transition towards more sustainable vessel operations.
The containerised battery system is a modular energy storage solution developed for maritime applications. Designed for both retrofit and newbuild projects, it can be adapted to a wide range of vessel types and power requirements. According to eCap Marine, the system supports peak shaving, spinning reserve, silent harbour operation and the integration of additional renewable energy sources. By optimising engine load profiles and reducing auxiliary engine operation, it is intended to improve energy efficiency while lowering emissions and maintenance requirements.
For applications requiring emission-free onboard power generation over longer operating ranges, eCap Marine also offers scalable hydrogen power systems that can be implemented either as containerised solutions or as fully integrated onboard installations. Combining fuel cell technology with expertise in system engineering, integration and class certification, the systems are designed to generate electrical power using green hydrogen. Their modular architecture allows them to be adapted to different operational profiles and power requirements for both retrofit and newbuild projects.
At SMM, visitors will also be able to gain insights into hydrogen propulsion systems currently under construction, including system design, integration, certification and operational experience.
