Energy Storage Tank Cost

How much does a storage tank cost?

Storage tank costs are tabulated in this data-file, averaging $100-300/m3 for storage systems of 10-10,000 m3 capacity. Costs are 2-10x higher for corrosive chemicals, cryogenic storage, or very large/small storage facilities. Some rules of thumb are outlined below with underlying data available in the Excel.

What are the benefits of a thermal energy storage tank?

A Thermal Energy Storage tank can provide significant financial benefits starting with energy cost savings. The solution can reduce peak electrical load and shift energy use from peak to off-peak periods. You can also avoid costs by incorporating a TES tank into your infrastructure.

How does a thermal energy storage tank work?

The diffuser system stratifies the water in the tank, which optimizes the energy storage capacity. A Thermal Energy Storage tank can provide significant financial benefits starting with energy cost savings. The solution can reduce peak electrical load and shift energy use from peak to off-peak periods.

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.

Why are LNG storage tanks so expensive?

LNG storage tanks thus come in as some of the most expensive storage facilities in the data-file, because they are very large and cryogenic. Higher capex may be worthwhile to install higher grade tanks that minimize boil-off and improve energy efficiency.

How much does hydrogen storage cost?

Higher capex may be worthwhile to install higher grade tanks that minimize boil-off and improve energy efficiency. Large-scale hydrogen storage would likely be higher cost than LNG storage, in our view, and the median small-scale facility for cryogenic or ultra-compressed hydrogen storage is estimated to cost $8,000/m3.
