comparison of air energy storage and pumped hydro energy storage costs

Is hydrogen storage better than pumped hydro?

Based on the given assumptions for , hydrogen storage is more favorable than pumped hydro. While the reductions in Levelized Energy Cost (LEC) for pumped hydro and compressed air storage are only 10% and 20% respectively, hydrogen storage shows a 70% reduction.

What is the difference between long-term storage and pumped hydro storage?

For long-term deployment, the picture changes. While pumped hydro storage remains a viable option, other storage systems like compressed air and hydrogen may become more cost-effective. For medium-term deployment, there are reductions in LEC of around 40% for pumped hydro, 45% for compressed air storage and 70% for hydrogen storage.

Which energy storage technologies are included in the cost and performance assessment?

The Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

Does hydrogen storage surpass pumped hydro?

Based on the assumptions made for , hydrogen storage surpasses pumped hydro in terms of average, discounted costs of energy storage. Even the costliest variant of hydrogen storage is only half the cost of pumped hydro.

How much does pumped storage cost?

Pumped storage, when additionally compared on an energy basis, offered a very low cost of $19/kWh-yr using values if compared to the battery storage technologies, as shown in Figure 5.3. Figure 5.4 shows the results of the remaining non-battery technologies, which have been annualized on a $/kW power basis as opposed to a $/kWh energy basis.
