Storing electricity at the bottom of the ocean is the new concept from the German engineer Rainer Schramm [136] and could be very effective with an efficiency of around 80%, comparable to conventional energy storage systems. This energy storage system makes use of the pressure differential between the seafloor and the ocean surface.

In order to absorb the regenerative braking energy of trains, supercapacitor energy storage systems (ESS) are widely used in subways. Although wayside ESS are widely used, because of the influence of no-load voltage, and so on, a wayside ESS cannot absorb all the regenerative braking energy in some special cases,
Fig. 12 shows a scheme of a typical hydrogen system for electrical energy storage. First, electric energy is used to produce hydrogen (and oxygen) in the electrolyser, which is then stored by using a method shown in Fig. 11. The stored hydrogen can be used subsequently by the fuel cell system to produce electricity or extracted
