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.
