Abstract: In light of the energy transition and the need to reduce emissions, efficient and capable energy storage devices are needed. Different concepts will have their individual pros and cons, an energy storage device placed subsea would provide high energy densities, long lifetime, and high efficiencies given that the unit could be designed so that it takes advantage of the cooling effects of the ocean.
