What is energy stored on invested (ESOIe) ratio?

The energy stored on invested (ESOIe) ratio of a storage device is the ratio of electrical energy it dispatches to the grid over its lifetime to the embodied electrical energy § required to build the device.24 ¶ We restate equation (1) as The denominator is the sum of the embodied energies of each individual component of the system.

How does energy-to-power ratio affect battery storage?

The energy-to-power ratio (EPR) of battery storage affects its utilization and effectiveness. Higher EPRs bring larger economic, environmental and reliability benefits to power system. Higher EPRs are favored as renewable energy penetration increases. Lifetimes of storage increase from 10 to 20 years as EPR increases from 1 to 10.

What is energy-to-power ratio?

The energy-to-power ratio R is directly proportional to the duration over which a storage system can continuously dispatch power from its fully charged state at maximum power (the maximum dispatch time is given by R × ηFC). It is an important factor governing the net energy balance of a RHFC system (Fig. 3).
