Energy storage, both in its electric and thermal forms, can be used both to transfer energy from shore to the ship (thus working similarly to a fuel) or to allow a better
US Navy Photo SAN DIEGO – The Department of Defense last month issued a small contract for a Navy project to develop and provide a modular energy storage system for its newest vessels including its all-electric DDG-1000 class of surface combatants.
Implementation of thermal energy storage on ships Thermal energy storage technologies have been applied in many other fields, where balancing of mismatch between energy production and demand is required.
“The Navy approached us about replacing one of the weapons systems on the DDG-1000 with large-scale energy storage. That’s an electric ship. So we said, yeah, we think we could do that,” Higier said, noting “it was the fastest solicitation-to-award in my portfolio,” with the contract awarded in just over a month.
There may be scope to adapt some power industry thermo-chemical energy storage developments for future application in maritime propulsion, especially as future oil prices rise.
Consider a 14000 teu New Panamax container ship, a common size in trans-oceanic shipping. The power required to propel the ship at a design speed of 21.5 knots is 40.09 MW . At a reduced slow steaming speed of 16 knots, the required power is 16.38 MW assuming a cubic power curve for frictional resistance.
A reasonably sized on-board battery could be charged fully with the ship's main engines during cruising, and then depleted to supply hotel load during port operations. Such methods, coupled with supplying the hotel load from a shore connection, would have a major impact in reducing local emissions in harbors.
