Executive Summary
Introduction
Charge as outlined in HB589.
Definition of storage:
- Focused on storage and dispatch of electricity
- Needs to have directional capability, i.e., convert electricity to another form of energy for storage, then convert back to electricity
Storage Technologies
- Lithium-ion batteries
- Flow batteries
- Compressed Air
- Flywheels
- Ice storage
- Water heaters
- Electrolyzers->H2 storage->fuel cell
- Vehicle to grid batteries
Provide description of each technology along with most up-to-date cost information.
Can we provide a very simple spreadsheet analysis for each one? Assuming x hours of storage and a set of standardized assumptions, what is
- the estimated dispatch cost ($/kWh)
- Capacity cost ($/kW)
