Grid Storage Cost Calculator

Interactive tool comparing LCOE for lithium-ion, flow batteries, pumped hydro, and thermal storage by duration.

Key Highlights

  • 4 storage technologies compared
  • LCOE by discharge duration (1h to 100h)
  • Round-trip efficiency analysis
  • Cycle life and degradation modeling
  • Location-specific energy pricing

Overview

An interactive calculator comparing the Levelized Cost of Energy (LCOE) for grid-scale storage technologies. Compare lithium-ion, flow batteries, pumped hydro, and thermal storage across different discharge durations.

What's Inside

Technology Comparison

Lithium-ion dominates short-duration (1-4h) storage at $150-300/kWh. Flow batteries excel at 4-10h durations. Pumped hydro and thermal storage win for long-duration (10h+) applications. The calculator models all four with current pricing.

Sensitivity Analysis

Adjust cycle frequency, electricity prices, and discount rates to see how LCOE changes. The tool highlights the optimal technology for each use case.
