MN: Corvus Energy

Posted by Nicole Ventimiglia

The Company:
Corvus is a manufacturer of proven, high power Energy Storage Systems (ESS). Its field proven battery systems provide power to hybrid and fully electric marine propulsion systems. Founded in 2009, Corvus provides purpose-engineered ESS solutions for marine, oil & gas and port applications. Using a customer’s load profile, Corvus engineers design an ESS tailored to the customer application without the expense of custom engineering. The only purpose designed industrial lithium-ion battery system; it is scalable from 6.5 kWh at 48VDC to multiple Megawatt-hours and 1100VDC. New liquid cooled battery modules support more aggressive load profiles with a smaller battery system, reducing total capacity required as well as space and weight. Battery hybrid propulsion increases the energy efficiency of a vessel by optimizing the operation of its diesel engines applying the battery system energy in lower power ranges and when extra power is needed, thus lessening dynamic load changes allowing engine operation at relatively constant power levels. Workboats spend most of their time maneuvering into position and only operate at full power for brief periods. This system allows for significant fuel savings and emission reductions. 

The Case:
Corvus manufactures energy storage systems (ESS). Its field proven battery systems provide power to hybrid and fully electric large marine propulsion systems and is the world’s first lithium battery module to have all the Marine Standards and Type Approvals (DNV, Lloyd’s and ABS). Corvus has the largest installed base of ESSs with the largest number of projects completed in the maritime industry. 90 percent of commercial hybrid vessels utilize a Corvus ESS.
