MARINE EDGE Selects CAP-XX Liquid-Cooled Supercapacitor Modules for its PowerEdge Hybrid Propulsion System for Cargo Ships

The technologies combine to create a regenerative power management system which increases energy efficiency, saves fuel and reduces emissions using the motion of the ocean waves

CAP-XX Limited (LSE:CPX), the leading manufacturer of ultra-thin prismatic, cylindrical, and Lithium-Ion supercapacitors, announces that MARINE EDGE, an innovative company making maritime transportation more sustainable, has selected and made its first orders of CAP-XX's large, powerful, liquid-cooled supercapacitor modules for its PowerEdge system installations for cargo ships which reduce fuel consumption and minimise emissions.

CAP-XX's powerful, 96V, 83F, liquid-cooled supercapacitor modules store and release the large amounts of energy generated from the periodical variations in engine loads induced by ocean waves in MARINE EDGE's PowerEdge regenerative hybrid power management system. This sustainable, environmentally-friendly system improves a cargo ship's overall propulsive efficiency, and decreases fossil fuel consumption and CO2 emissions by flattening wave load variations on the main engine.

MARINE EDGE chose CAP-XX supercapacitors for their high efficiency, longevity and modularity, which allows installation on a variety of ships with different configurations, while maintaining their ability to handle high currents effectively for millions of cycles.

The 96V, 83F CAP-XX liquid-cooled supercap modules feature:

·    Liquid Cooled to provide extremely high-rate charge and discharge capability

·    Maintenance free operation

·    10-year life with heavy charge/discharge cycling

·    Meets Rail Shock and Vibration Standard

·    Modules configurable to 2000 Volts

"The CAP-XX supercapacitor module, with its compact build and millions of cycles, is a key enabler for our PowerEdge system to save energy and fuel burn on cargo ships. To be a game-changer for sustainable marine transportation we must incorporate the most advanced hardware available," said Nevo Dotan, CEO of MARINE EDGE.

"Our expertise in creating sustainable systems which capture environmental energy from solar, wind, vibration and motion sources pairs perfectly with MARINE EDGE's quest to make cargo ships more efficient," said Marco Ranalli, General Manager EMEA at CAP-XX. "This is just one example of how our new line of large, powerful supercap modules meet the requirement for power management in demanding applications."
