Battery Energy Storage System – BESS

Together with our partner Lehmann Marine, a leading supplier of safe and compact maritime battery systems, we have jointly developed the eCap Battery PowerPac for the maritime industry. This containerised and mobile Battery Energy Storage System (BESS) serves as a flexible and scalable power supply solution on board or in port.  The system features a battery setup by Lehmann Marine with electrical components to provide either DC or AC output, depending on operational needs.

Our solution offers scalable capacity tailored to your application needs, with flexible configurations available as battery-only, hybrid (battery plus fuel cell), or as a high-power charger for ports. Designed as a mobile, containerised plug-and-play system, it enables fast installation on board, significantly reducing off-hire time. Built with maritime-certified components, it provides a zero-emission power source supported by an integrated safety and power management system for reliable, efficient performance.

Our solution is designed to support a wide range of maritime operations. It can serve as a reliable emergency power source during maintenance or unexpected outages, or as a swappable battery system for vessels operating on tight schedules. The containerised design makes it easy to extend machinery rooms and seamlessly integrate additional capacity. Reducing diesel generator usage in port and on the last mile into port areas helps lower emissions while improving efficiency. It also enables peak shaving and provides spinning reserve while transiting in channels or operating in DP mode. Additionally, it functions as a fast charging station for electric and hybrid vessels in ports, ensuring smooth, sustainable operations across the maritime sector.
