7. Summary

There are variety of ESS technologies. ESS Technologies are selected by project requirements such as energy, power, lifetime and cost, and tolerances to technology risks.

‘Energy Community’ projects have emerged in the

world. The requirements to ESS are different depending on the various factors such as purposes, goals, types of stakeholders and budget. One of the keys is the selection or combination of ESS technologies.

Hitachi Chemical offers variety of ESS technologies. Happy to support to determine ESS technologies and scales.
