The growing concern of limiting the negative impact of shipping on the environment mean that clean technologies are becoming more and more important. The trend to design more efficient and versatile ships have increased the variety in energy management systems.

The objective of the work is to enhance the energy management systems onboard with Molten salt Thermal Energy storage (MSTES). The energy storage system providing a buffer source of energy, and ability to utilize the stored energy accordingly. The operation includes passage of salt through heat exchangers gaining thermal energy. Liquid salt is kept in an insulated storage tank, where volumes can be adjusted to provide the necessary storage capacity for every application and location. It is a reliable option for storing renewable energy, and a flexible, cost-efficient addition to existing infrastructure and systems. Additionally, providing benefits including peak shaving, enhanced dynamic performance and spinning reserve.

The novel feature of the work includes its ability the utilize the wide range of sources available onboard that would otherwise go unused and providing the ability to be future proof to the ships considering existing and upcoming regulations.
