Corvus Blue Whale NxtGen – Energy

Corvus Blue Whale NxtGen Energy: LFP marine battery for large vessels, 1 MWh to 200+ MWh, 24.12 kWh / 77 VDC modules, liquid or air cooled, up to 1232 VDC, for long zero-emission sailing and port stays.

Description

The Corvus Blue Whale NxtGen – Energy is a high-energy marine battery system for medium to large vessels, including retrofits, with system sizes from 1 MWh to 200+ MWh. It is optimised for slow charge and discharge but can deliver high rates for short periods, enabling longer zero-emission sailing and emission-free port stays.
