Comprehensive electricity cost of electrochemical energy storage

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

Could a low-cost electrochemical battery serve the grid?

The energy storage capacity could range from 0.1 to 1.0 GWh, potentially being a low-cost electrochemical battery option to serve the grid as both energy and power sources. In the last decade, the re-initiation of LMBs has been triggered by the rapid development of solar and wind and the requirement for cost-effective grid-scale energy storage.

What are the different types of energy storage technologies?

The examined energy storage technologies include pumped hydropower storage, compressed air energy storage (CAES), flywheel, electrochemical batteries (e.g. lead–acid, NaS, Li-ion, and Ni–Cd), flow batteries (e.g. vanadium-redox), superconducting magnetic energy storage, supercapacitors, and hydrogen energy storage (power to gas technologies).

What are the characteristics of electrochemistry energy storage?

Comprehensive characteristics of electrochemistry energy storages. As shown in Table 1, LIB offers advantages in terms of energy efficiency, energy density, and technological maturity, making them widely used as portable batteries.

How to evaluate the cost of energy storage technologies?

In order to evaluate the cost of energy storage technologies, it is necessary to establish a cost analysis model suitable for various energy storage technologies. The LCOS model is a tool for comparing the unit costs of different energy storage technologies.

What are energy related costs?

Energy related costs include all the costs undertaken to build energy storage banks or reservoirs, expressed per unit of stored or delivered energy (€/kWh). In this manner, cost of PCS and storage device are decoupled to estimate the contribution of each part more explicitly in TCC calculations.
