Energy storage costs of thermal power plants

Are thermal storage power plants better than conventional power plants?

The paper presents a cost comparison of thermal storage power plants (TSPP) with various conventional power plants. TSPP require less fuel and can better fulfill the demand of variable and intermittent residual loads through providing a much higher flexibility with their intrinsic heat storage system, also called Carnot Battery.

How much does thermal energy storage cost?

In our base case, the cost of thermal energy storage requires a storage spread of 13.5 c/kWh for a 10MW-scale molten salt system to achieve a 10% IRR, off of $350/kWh of capex costs. Costs are sensitive to capex, utilization rates, opex, electricity prices and round trip losses. The sensitivities can be stress tested in the data-file.

What is thermal energy storage?

Thermal energy storage in buildings can be used to adjust the timing of electricity demand to better match intermittent supply and to satisfy distribution constraints. TES for building heating and cooling applications predominantly utilizes sensible and latent heat technologies at low temperatures (i.e., near room temperature).

What are the different types of thermal energy storage?

This study is a first-of-its-kind specific review of the current projected performance and costs of thermal energy storage. This paper presents an overview of the main typologies of sensible heat (SH-TES), latent heat (LH-TES), and thermochemical energy (TCS) as well as their application in European countries.

What is the total investment cost of a power plant?

The total investment cost consists of the EPC cost, EPC contracting fees and owner's costs. For conventional power plants, EPC costs include mechanical system costs, electric system costs, civil costs, and indirect costs.

What is the Technology Strategy assessment on thermal energy storage?

This technology strategy assessment on thermal energy storage, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.
