Lehmann Marine

A German technology leader in maritime LFP (Lithium Iron Phosphate) battery systems

Lehmann Marine is a Germany-based leader in the shipping industry’s advanced lithium iron phosphate (LFP) battery systems. The company’s innovative energy solutions are designed to meet the evolving needs of maritime operators, offering safety, reliability, and sustainability through cutting-edge German engineering.

The key to success lies in the well-thought-out concept of Lehmann Marine’s battery systems. The modular and flexible design allows for easy adaptation of the batteries to the individual requirements of various ships. This configurational flexibility, combined with straightforward maintenance due to small and easily accessible battery modules, gives customers unprecedented efficiency and reliability.

Another significant advantage is the enhanced safety of lithium iron phosphate (LFP) cells. Compared to traditional nickel-manganese-cobalt (NMC) batteries, LFP batteries are considerably safer, even in extreme situations where thermal runaway may occur, as they are not susceptible to fire. In the event of thermal runaway, only gas is released and vented outside. This feature renders Lehmann Marine’s LFP battery solutions more environmentally friendly and markedly safer for use on board ships.

Lehmann Marine is part of the Sunlight Group, a major global player in energy storage systems, and benefits from Sunlight’s large capacities and excellent supplier and service network.

Marine batteries are used as energy storage and power supply for propulsion, significantly reducing fuel consumption, maintenance costs, and emissions. With improved capacity-to-weight ratio from lithium-ion technology and growing demand for lower emissions, batteries have become an increasingly attractive option for the large-scale energy supply in the maritime sector. Lehmann Marine is dedicated to supplying the marine industry with safe and compact energy storage solutions (ESS).

CUBE provides a modular design with superior energy density. The flexible energy storage is scalable from a few kWh to several MWh and enables an optimal use of space. Any scale of power storage is available by freely configuring modular units in strings of up to 1,000 VDC. They include an integrated Battery Management System (BMS), gas exhaust, pre-charge functionality and sophisticated air cooling technology for safe and reliable operation. CUBE is type-approved by Bureau Veritas, DNV, Lloyd’s Register and RINA.

An idea for an innovative and sustainable energy storage solution for shipping quickly grew into a medium-sized company with committed employees in a wide range of application areas. Our maritime battery systems are in great demand. We are continuing to grow and look forward to your help! You can find us in the idyllic Seevetal-Hittfeld. Our offices are conveniently located directly on the A1 on the southern edge of Hamburg.

Help us make shipping more sustainable and climate-friendly!
