Batteries: Looking Beyond Spinning Reserve
Mia Elg, R&D Manager at Deltamarin, says there’s not many of the company’s new designs, no matter what the vessel type is, that don’t include batteries.Installing smaller battery capacity to a diesel engine driven vessel with electrical power train can enable spinning reserve. Here, an optimal number of engines can be kept online, and the batteries can work as a black out preventer. This can save, depending on the type of the ship and operation, anything between a few percent…
