Ship engine energy storage

Can a shipboard energy management strategy reduce mission-scale fuel consumption?

Multiple requests from the same IP address are counted as one view. This paper proposes an advanced shipboard energy management strategy (EMS) based on model predictive control (MPC). This EMS aims to reduce mission-scale fuel consumption of ship hybrid power plants, taking into account constraints introduced by the shipboard battery system.

What is energy storage system integration?

Energy storage systems (ESS) integration is a key point for hybrid ships. On a first hand, integration of ESS allows an internal combustion engine to be operated at the most efficient range to minimize fuel consumption and so harmful emissions.

Can a ship's energy system be more efficient?

Extensive electrification of ship propulsion and shipboard power systems has been vastly proposed in the literature to make onboard energy systems more efficient. However, energy efficiency in the context of maritime transport is becoming even more stringent.

Is energy storage feasible for oceangoing ships?

Energy storage for oceangoing ships is very challenging with current technology and seems not feasible commercially in near future due to long and steady voyages and high-power requirements. However, hybrid power generation and propulsion are feasible for certain operational modes .

How does a hybrid energy storage system work?

Hou et al. used a hybrid energy storage system consisting of batteries and flywheels as a buffer to separate the load fluctuations from a ship power grid, to ensure the stability of the ship grid's voltage.
