How can energy be stored in a field?
$begingroup$ This answer is really just an argument that fields store energy (including, possibly, negative energy). For an argument that field energy contributes to inertia, you may need more detail than I can fit in a comment. But for reasoning that kinetic energy contributes to inertia, look for a history of the phrase "relativistic mass." Then imagine a sealed box
Energy Storage: Overview, Types & How It Works
The duration for which energy can be stored depends on the type of energy storage system. Batteries typically store energy for hours to days, while pumped hydro and compressed air systems can store energy for weeks or even months. Thermal energy storage durations vary depending on the material used, ranging from hours to days.
Energy storage
The stored energy can be released to the network by discharging the coil. The associated inverter/rectifier accounts for about 2–3% energy loss in each direction. SMES loses the least amount of electricity in the energy storage

Can You Store Electricity for Later?
Well, we can convert it into other forms of energy that can be stored. For example, batteries can convert electrical energy into chemical potential energy. Other systems can convert electrical energy other types of energy. Examples include mechanical and gravitational potential energy. We can convert them all into electrical energy when we need it.

What is stored energy?
An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position.
