How it Worked. Radioisotope thermoelectric generators (RTGs) provide electrical power to spacecraft using heat from the natural radioactive decay of plutonium-238, in the form of plutonium oxide. The large difference in temperature between this hot fuel and the cold environment of space is applied across special solid-state metallic junctions ...
The new Full E-RTG system solution is already in operational use at the Port of Tanjung Pelepas. With Full E-RTG, cranes can now travel up to 1,500 meters (1,640 Yards) on power from the energy-storage system. Previously, the port cranes were only up to 90 percent electrically driven after switching from diesel to electric mode.
An optimal energy management model for the grid-powered electric RTG crane is developed. •. The RTG crane is retrofitted with a battery storage system and has energy recovery abilities. •. The model aims to minimize the operation cost subjected to the maximum demand charges and to the Time of Use pricing structure. •.

The study aims to design optimal control strategies for the power flows associated with the energy storage device, considering the highly volatile nature of RTG crane demand and difficulties in …
An Energy Storage System (ESS) is a significant tool for a more energy efficient ecosystem and help to decrease environmental concerns [1,2]. In general, the objective of an ESS is to reduce the cost of electricity and avoid the need to upgrade the distribution network by shifting energy consumption from peak to valley periods [2].
According to current research, this paper is the first to apply the game theory to the energy management of a hybrid RTG crane. This paper also discusses the hybrid system structure and device sizing issues. The hybrid RTG crane consisted of a 20-kW DG, a 73.9-kWh lithium battery pack, and a 22-F SC pack.
