1. Pure Battery-powered Ship

Pure battery-powered ships use lithium batteries (or supercapacitors, fuel cells) as the power source and electric propulsion. The equipment composition is simple and reliable and can achieve zero pollution emissions, low vibration, and low noise. The battery (or supercapacitor) is configured according to the ship's endurance requirements.

2. Diesel-Electric Hybrid Ship

Series hybrid power system uses diesel generator sets and lithium battery (or supercapacitor) as power source. The electric motor drives the propeller. The diesel generator sets and battery  (or supercapacitor) can output in parallel or independently depending on the load power. Diesel generator sets operates at variable speed and has low overall fuel consumption rate.

3. Parallel Hybrid Ship

Parallel hybrid system uses a shaft reversible motor + main engine driven propeller, which can realize multiple working modes of pure electric propulsion (PTH), shaft power generation (PTO) and hybrid propulsion (PTI). The system has high safety redundancy and part of flight segments are zero-emission.
