Energy storage is gaining traction as an essential component for maintaining load-generation balance in the modern electricity market. Viewed as a promising solution to a widespread challenge, long-duration energy storage (LDES) may be the key to counteracting the pitfalls of variable renewable power generation, especially as we look toward the industry’s aspiration of a zero-emission world. However, these technologies are enduring their own challenges to mass adoption compared to some of the more traditional lithium-ion storage technologies. These include a lack of a revenue-generating framework to drive capital deployment, an undefined long-duration reserve framework forcing competition with short-duration project markets and a lack of commercial-scale development on which to lean to prove successful implementation.
If dependent on a pure energy arbitrage business model, the major needle movers on a project’s balance sheet become capital cost, average spread per cycle and the yearly cycle frequency. Assuming a $72,000/MWh capital cost for a 10 MW/1,000 MWh iron-air project, Enverus Intelligence® | Research (EIR) can derive the required breakeven arbitrage spread required for a 10% return on equity (at various cycle counts per year) and the maximum spread achievable in each market over the past five years. Figure 1 reveals that even with low capital costs, the energy arbitrage model fails to produce a financially promising project across all ISOs, irrespective of cycle count. Thus, EIR looks to a significant widening of seasonal location market pricing spreads or the addition of alternate revenue streams to justify confident investment in these 100+ hour LDES projects.
