SuperBattery-based energy storage solutions
for high power marine applications

Back-up Power
Back-up Power

SuperBatteries provide a reliable and fail-safe power supply for marine vessels in the event of a main power loss, allowing critical equipment to remain operational. This back-up power solution provides peace of mind and ensures smooth, uninterrupted operations even in the most extreme conditions.

Peak power
Peak Power shaving

SuperBatteries can be used to shave peak power for ships, providing increased stability on the ship's grid and improved power supply while minimizing wear and tear on generators due to reduced mechanical stress. This helps keep ships running smoothly and efficiently for longer periods of time.

Active heave & motion compensation

SuperBatteries are more competitive and reliable than pneumatic accumulators when it comes to recovering energy and providing peak power to motion compensated pile grippers and similar marine heavy equipment. While ensuring vertical stability of the crane payload in offshore operations, SuperBattery-based energy storage systems are the best technology to save fuel and improved power control in bad sea conditions

Parallel Hybrid
Parallel Hybrid Propulsion

Parallel hybrid propulsion with SuperBatteries for ships offers improved fuel savings and reduced mechanical wear on the propeller drive train. This hybrid propulsion solution helps to increase efficiency and improve the longevity of vessels over time.

Spinning Reserve
Spinning Reserve

The use of a SuperBattery for ships to provide spinning reserve eliminates the need for additional generators, while operating gensets at optimal load helps reduce fuel consumption. This is an effective way to achieve redundancy and save costs at the same time.

Engine gradient support
Engine gradient support

By employing a SuperBattery to support engines, ships can maintain grid stability with quick load response. This energy storage solution can also help save costs and improve efficiency.
