Caterpillar’s CMB-1 Marine Battery
Caterpillar’s CMB-1 Marine Battery offers an innovative solution that helps the shipping industry reduce its environmental footprint. Aligned with global climate goals, the CMB-1 helps shipowners cut their emissions without compromising performance. With a modular design and high energy density, the CMB-1 delivers flexibility and efficiency, and Pon Power, as the proud supplier of this technology, is paving the way toward a greener maritime future.
The Power of Electrification: Lower Emissions, More Efficient Sailing
The maritime sector is embracing the challenge of reducing its environmental footprint, encouraged by international targets that set a vision of net-zero emissions by 2050. These objectives drive innovation and create opportunities for sustainable ship development. In this context, Caterpillar has developed a marine battery, resulting in the Cat CMB-1. With this, Pon Power offers shipowners the opportunity to take their vessel’s efficiency to the next level and even operate entirely emission-free.
The battery, fully scalable in 28.7 kW modules, can serve as the core of both hybrid and fully electric ship systems. In a hybrid vessel, the battery works alongside traditional engines; in fully electric ships, the batteries provide propulsion, storing environmentally friendly energy for quiet, efficient, and emission-free sailing.

Flexibility and maximum energy density
The Cat CMB-1 stands out with its innovative modular design, which can be flexibly adapted in both power and dimensions. This makes the battery suitable for a wide range of vessel types and operational requirements. With an impressive energy density of 7.6 kg/kWh and a volumetric energy density of 4.6 l/kWh, Pon Power offers shipowners the ability to implement customized energy solutions tailored to the needs of each vessel.
Bjorn Hoefnagels, Manager Clean Marine at Pon Power: “The high energy density of the CMB-1 means efficiency, allowing the battery to deliver more energy within a compact space. Additionally, the modularity provides a easily scalable system, enabling us to create a perfect fit for every battery room. It also means that when a vessel’s energy requirements or operating profile change, the system can be expanded or adjusted without major revisions to the existing design.”

Reliability
Caterpillar’s CMB-1 Marine Battery provides shipowners with the reassuring reliability of the CAT brand. Caterpillar’s reputation is built on over a century of innovative and highly dependable energy solutions. The American brand only brings products to market once their value and performance have been thoroughly proven. This battery stands out not only for its quality and long lifespan of ten years or more, but also for the extensive durability tests that ensure the product remains reliable under the most challenging conditions.
With a global market presence, Caterpillar not only offers a robust, high-quality product but also access to top-tier service and support networks with experienced technicians to ensure every installation performs optimally. While competitors are often still establishing their brand, Caterpillar provides the assurance of integrated systems that are recognized and trusted worldwide, delivering the reliable support every maritime operation needs for long-term success.
