What factors affect energy storage cost?
Operation and cost of electricity purchase have a high influence on storage cost. The ratio of charging/discharging unit power and storage capacity is important. PSH and CAES are low-cost technologies for short-term energy storage. PtG technologies will be more cost efficient for long-term energy storage.
What is energy storage system capacity cost?
Energy storage system capacity cost as a function of energy storage roundtrip efficiency for various technologies (boxes) compared to breakeven capacity costs for various loan periods (LP).
How do price differences influence arbitrage by energy storage?
Price differences due to demand variations enable arbitrage by energy storage. Maximum daily revenue through arbitrage varies with roundtrip efficiency. Revenue of arbitrage is compared to cost of energy for various storage technologies. Breakeven cost of storage is firstly calculated with different loan periods.
How much does a solar energy system cost?
The system is assumed to operate at 1 cycle per year and with an electricity cost of 3 €ct/kWh. For all technologies the arithmetic average of costs is used.
How much does charged electricity cost?
The cost of charged electricity is varied between −5 and +5 €ct/kWh. The LCOS varies only slightly for PSH, CAES and battery technologies with differing cost of electricity, while the LCOS of the PtG technologies is more cost sensitive.
Why is discharged electricity more expensive than pure electricity?
For all technologies which use only electricity in the discharging process (as opposed to dCAES systems, which use also gas), the cost of discharged electricity is therefore higher than the cost of pure electricity storage plus the cost of charged electricity. The overall efficiency of the plant needs to be taken into account as well.
