We estimate that cost-competitively meeting baseload demand 100% of the time requires storage energy capacity costs below $20/kWh. If other sources meet demand 5% of the time, electricity costs fall and the energy capacity cost target rises to $150/kWh.
Ranges of storage power capacity costs ($0–$2,000/kW) and energy capacity costs ($0–$300/kWh) were used as simulation inputs, in order to cover a variety of cost combinations for current and potential future technologies.
According to the DOE OE Global Energy Storage Database, since 2010, more than 50% of energy storage projects are LIB projects . By contrast, although PHES accounts for 93% of the global storage capacity , many of PHES, particularly plants in Europe and US, were built before 1990 .
The costs of energy from optimized systems are summarized in Figure 3 for two different storage technology cost structures, with power and energy capacity costs of $1,000/kW and $20/kWh (Tech I) and $700/kW and $150/kWh (Tech II).
