H-field energy can be scavenged through electromagnetic induction. On the other hand, intensive E-field is present in the vicinity of high potential conductors. Strictly, EEH and MEH are "stealing" rather than harvesting or recovering waste energy, because the very essence of electricity lies in the electromagnetic field itself.
Energy can be reversibly stored in materials within electric fields and in the vicinity of interfaces in devices called capacitors. There are two general types of such devices, and they can have a wide range of values of the important practical parameters, the amount of energy that can be stored, and the rate at which it can be absorbed and released.
