6 FAQs about [Basis for the ratio of new energy storage]

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.

Do energy storage technologies provide flexibility in energy systems with renewable sources?

Storage technologies are a promising option to provide the power system with the flexibility required when intermittent renewables are present in the electricity generation mix. This paper focuses on the role of electricity storage in energy systems with high shares of renewable sources.

Why do energy systems need more storage facilities?

Future energy systems require more storage facilities to balance the higher share of intermittent renewables in the upcoming power generation mix (Benato and Stoppato, 2018), especially as the demand for electric power could push capacity to 7200 GW by 2040 (International Energy Agency, 2014).

What is ESOIe ratio?

The first is the ESOIe ratio, which indicates how efficiently a storage system leverages energy inputs that are external to the energy storage process. |||| These energy inputs occur during the manufacturing phase of the storage system's life cycle, for preparing materials and assembling the system.

Why does the ESOI E ratio of storage in hydrogen exceed a battery?

The ESOI e ratio of storage in hydrogen exceeds that of batteries because of the low energy cost of the materials required to store compressed hydrogen, and the high energy cost of the materials required to store electric charge in a battery.

What is the energy return on energy invested ratio of CCS projects?

We estimate the electrical energy return on energy invested ratio of CCS projects, accounting for their operational and infrastructural energy penalties, to range between 6.6:1 and 21.3:1 for 90% capture ratio and 85% capacity factor.
