6 FAQs about [The era of on-board energy storage]
Can onboard energy storage devices reduce the catenary energy consumption?
Abstract: For improving the energy efficiency of railway systems, onboard energy storage devices (OESDs) have been applied to assist the traction and recover the regenerative energy. This article aims to address the optimal sizing problem of OESDs to minimize the catenary energy consumption for practical train operations.
How does on-board energy storage affect a ship's energy management strategy?
The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy. Previous research in this area consists of detailed modelling, design, and comparisons of specific on-board power systems for explicitly defined operational profiles.
Can onboard energy storage systems be integrated in trains?
As a result, a high tendency for integrating onboard energy storage systems in trains is being observed worldwide. This article provides a detailed review of onboard railway systems with energy storage devices. In-service trains as well as relevant prototypes are presented, and their characteristics are analyzed.
Can energy storage be integrated into on-board power systems?
While there is some overlap, the maritime industry poses specific challenges to the successful integration of energy storage into on-board power systems: size and weight are of greater importance, the power system is isolated for most of the time and the load characteristic of propellers favours mechanical propulsion.
How efficient is energy storage in a ship?
The relative efficiency of using batteries varies between -48% and + 57%. Energy storage has the potential to reduce the fuel consumption of ships by loading the engine (s) more efficiently. The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy.
