Executive Snapshot and Market Trajectory

Form Energy's first commercial-scale iron-air deployment in Minnesota has shifted long-duration grid storage from pilot demonstration to signed utility contract, pulling investor and competitor attention toward a chemistry few took seriously five years ago, when lithium-ion dominated every storage conversation happening across the entire industry.
Grid-scale storage now drives the fastest revenue growth in the category, even though zinc-air primary cells for hearing aids still account for the largest single volume base across the entire industry worldwide. Iron-air batteries specifically target the 100-hour-plus discharge window that lithium-ion struggles to serve economically, and utility procurement teams in the United States are increasingly writing multi-year supply agreements around that specific duration gap rather than treating it as a distant future consideration.
Five manufacturers still account for most disclosed capacity, but Chinese and Indian entrants are moving quickly on aluminum-air and rechargeable zinc-air variants aimed at cost-sensitive backup power applications across emerging markets. Materials science remains the binding constraint industry-wide: rechargeable cycle life still trails lithium-ion by a wide margin across every metal-air chemistry except the long-duration, low-cycle iron-air design purpose-built for infrequent full discharge cycles and single-day-plus events.
Market Definition
This market covers primary and rechargeable metal-air batteries, zinc-air, iron-air, aluminum-air, and lithium-air cells, sold for portable, grid-storage, and transportation applications. It excludes lithium-ion, nickel-metal hydride, and flow battery chemistries that do not use an air cathode.

Metal Air Battery Market Forecast Scenarios

metal-air-battery-market-size-forecast-scenario-1787325624137
Between 2020 and 2025, the market grew at a historical rate near 12.6 percent, carried mainly by steady zinc-air primary cell demand, as grid-scale iron-air deployment remained confined to pilot projects and early demonstration plants rather than signed commercial contracts with utilities across the United States or comparable markets abroad watching the technology's early results closely.
The base case assumes 14.6 percent annual growth through 2036, built on three mechanisms: Form Energy's commercial-scale iron-air manufacturing ramp in West Virginia, expanding utility procurement of long-duration storage to meet renewable integration mandates across multiple US states, and growing aluminum-air adoption in Indian and Southeast Asian two-wheeler and backup power applications where cost sensitivity favours the chemistry's simple, low-cost cell design over premium lithium-ion alternatives entering the same fleet segment.
A bull case near 15.8 percent depends on iron-air costs falling fast enough to win broader utility procurement against lithium-ion for shorter-duration use cases beyond its current niche market. The bear case near 13.4 percent reflects continued rechargeable cycle-life limitations, since several pilot zinc-air grid projects have underperformed their designed cycle count in field deployment across multiple sites and operating conditions.

A Mature Primary Cell Base Funds an Emerging Grid Chemistry

The metal-air category has quietly carried two very different businesses under one label for decades. Zinc-air primary cells for hearing aids are a mature, high-volume, low-margin manufacturing business built on decades of incremental engineering, while grid-scale iron-air storage is a capital-intensive, pre-scale business only now proving out commercial economics at meaningful volume for utility customers evaluating multi-decade infrastructure contracts, reliability commitments, and long-term m
TOP 5 CONCENTRATION42% CR5revenue share held by five largest global manufacturers

Commercial behaviour splits sharply by chemistry and end use. Primary cell manufacturers compete on unit cost and supply reliability for medical device customers who rarely switch suppliers once qualified, while grid-storage developers compete on levelised cost of storage against lithium-ion and increasingly against each other as more iron-air capacity comes online across multiple states and utility service territories each successive planning cycle and annual capital budget year.
The next decade turns on manufacturing scale-up execution. Iron-air's cost advantage over lithium-ion for long-duration applications depends entirely on reaching gigawatt-hour production volume, a threshold no metal-air grid chemistry has yet sustained commercially at full rate across multiple consecutive quarters of steady, uninterrupted output at full rated capacity nationwide and increasingly abroad as well.
"Nobody doubted the chemistry works. What took a decade was proving you could stamp out iron electrodes fast enough to matter to a utility's balance sheet."

Market Trends

Iron-Air Grid Storage Moves From Pilot to Commercial Contract

Form Energy's Weirton, West Virginia manufacturing facility began commercial-scale iron-air battery production in 2024, supplying a signed 100-hour storage contract with Great River Energy in Minnesota, the first utility-scale deployment of its kind at this discharge duration. The facility targets output equivalent to roughly 500 megawatt-hours of annual storage capacity once fully ramped, according to company disclosures. Xcel Energy and several other US utilities have since issued requests for proposals specifically naming long-duration iron-air storage as an eligible technology, a shift from generic storage procurement language used as recently as 2022.
Market Impact: Opens 6-state procurement pipeline

Aluminum-Air Range Extenders Gain Traction in Indian Two-Wheelers

Log9 Materials and other Indian developers have begun piloting aluminum-air range-extension modules for electric two-wheelers and three-wheelers, targeting a market where battery cost sensitivity outweighs the chemistry's non-rechargeable, replace-the-electrode limitation. Early pilots suggest a per-kilometre cost roughly 30 percent below equivalent lithium-ion range extension for high-utilisation commercial fleet vehicles covering more than 100 kilometres daily. India's FAME-II subsidy scheme does not currently distinguish battery chemistry, letting aluminum-air modules qualify for the same incentives as lithium-ion competitors entering the same fleet segment across multiple state markets already running active pilot programmes today.
Market Impact: Sustains 430M-person patient base

Market Opportunities and Growth Drivers

US Renewable Integration Mandates Favour Long-Duration Storage

State-level clean energy mandates in California, Minnesota, and New York increasingly require utilities to procure storage capable of multi-day discharge to firm intermittent renewable generation, a duration window lithium-ion serves poorly on a levelised cost basis beyond roughly four hours. The US Department of Energy's Long Duration Storage Shot programme has committed research and demonstration funding specifically targeting technologies like iron-air that can reach 100-hour discharge economically. Utilities in at least six states have issued long-duration-specific procurement solicitations since 2023, a category that barely existed in utility planning documents five years earlier.
Market Impact: Limits cycles to 300 to 500

Hearing Aid Demand Sustains the Zinc-Air Primary Cell Base

Global hearing aid unit shipments continue rising as ageing populations in Japan, Germany, and the United States expand the addressable patient base, sustaining steady demand for zinc-air primary cells that remain the dominant power source for non-rechargeable hearing aid models. The World Health Organization estimates disabling hearing loss affects over 430 million people globally, with treatment rates still well below potential in several large markets. This stable, predictable demand base gives established manufacturers like Duracell and Panasonic Energy reliable cash flow to fund adjacent grid-storage and EV chemistry research programmes.
Market Impact: Raises capex 20 to 35%

Market Restraints and Challenges

Rechargeable Cycle Life Trails Lithium-Ion Substantially

Most rechargeable metal-air chemistries still degrade after several hundred charge cycles, roughly a third of what comparable lithium-ion cells now achieve in commercial deployment. The root cause is that oxygen reduction and evolution reactions at the air cathode degrade catalyst materials faster than lithium-ion's intercalation chemistry degrades its electrodes over comparable use. This limits rechargeable zinc-air and lithium-air applications to use cases tolerant of shorter operational life. Researchers at several universities are pursuing bifunctional catalyst coatings intended to slow this degradation, though none has yet reached commercial-scale production validation at meaningful manufacturing volume.
Market Impact: Adds 500 MWh annual capacity

Air Cathode Manufacturing Lacks Standardised Supply Chains

Unlike lithium-ion, which benefits from a mature global supply chain for cathode and separator materials, metal-air battery manufacturers largely source specialised air cathode components through custom or in-house processes. The underlying cause is that air cathode design varies considerably by chemistry and application, preventing the standardisation that drove lithium-ion cost declines over the past decade. This raises capital cost for new entrants building manufacturing capacity from the ground up. Form Energy and Panasonic Energy have both vertically integrated air cathode production specifically to control this bottleneck internally rather than depend on external suppliers still building comparable capability.
Market Impact: Cuts per-km cost by 30%

Segment CAGR and Growth Architecture

Segmentation follows battery chemistry, the classification manufacturers and utility procurement teams already use to distinguish products by electrode metal, rechargeability, and target discharge duration across every application this report covers, from hearing aids through grid-scale storage installations spanning multiple continents, regulatory environments, and utility procurement frameworks currently operating worldwide across every profiled market segment.
metal-air-battery-market-market-share-analysis-1787325624675

Iron-Air Long-Duration Grid Storage

Iron-air storage is the fastest-growing metal-air chemistry as Form Energy's commercial-scale manufacturing ramp converts pilot-project interest into signed multi-year utility contracts across the United States. The chemistry uses abundant, low-cost iron and air as active materials, reversing rust formation during charge and discharge cycles, a design purpose-built for roughly 100-hour continuous discharge rather than the shorter cycles lithium-ion serves well. Great River Energy and Xcel Energy have both signed early deployment agreements, and several additional state-level utilities have issued procurement solicitations specifically naming long-duration iron-air technology as an eligible category. Growth concentrates almost entirely in the United States for now, though European and Australian utilities have begun evaluating the chemistry for similar renewable-firming applications within their own grids.
CAGR 24.5%

Rechargeable Zinc-Air Batteries

Rechargeable zinc-air batteries grow fastest among near-term commercial chemistries as developers target backup power and behind-the-meter storage applications tolerant of moderate cycle counts. NantEnergy has deployed rechargeable zinc-air systems across telecom backup power installations in markets with unreliable grid infrastructure, where the chemistry's low material cost outweighs its cycle-life disadvantage against lithium-ion. Zinc8 Energy Solutions has pursued a flow-battery variant of the same chemistry targeting longer-duration commercial and industrial storage applications across multiple continents. Growth concentrates in emerging markets with unreliable grid power and in commercial backup applications where infrequent cycling makes the technology's cost advantage more relevant than its cycle-life limitation relative to lithium-ion alternatives competing for the same contracts.

Regional Architecture and Country Demand Map

East Asia and North America together account for more than half of global revenue, while South Asia and Pacific posts the fastest regional growth on expanding aluminum-air adoption across Indian electric two-wheeler and three-wheeler commercial delivery fleets nationwide each successive fiscal year of sustained growth.

North America

The United States drives regional growth through Form Energy's commercial iron-air manufacturing ramp in West Virginia and a growing pipeline of state-level long-duration storage procurement mandates across California, Minnesota, and New York. Federal Long Duration Storage Shot funding has provided demonstration-scale grants specifically supporting iron-air and other emerging chemistries competing against more established lithium-ion and flow battery alternatives already deployed at scale. Canada contributes a smaller share concentrated in remote and northern grid applications, where long-duration storage reduces diesel generator dependence for isolated communities far from the main transmission grid. Manufacturing investment concentrates around West Virginia and Minnesota, where Form Energy has built its primary production and initial deployment facilities close to early utility customers.
Share: 29% | CAGR: 15.8% (2026 to 2036)

Western Europe

Germany anchors regional demand through its established zinc-air hearing aid manufacturing base and growing interest in long-duration storage to firm an increasingly renewable-heavy grid mix as coal capacity retires. The United Kingdom follows with early-stage iron-air and zinc-air grid storage pilots tied to its net zero commitments, though procurement remains smaller in scale than comparable US programmes to date. Switzerland maintains a disproportionate manufacturing footprint through Renata SA's hearing aid battery production, serving both domestic and export medical device markets globally across dozens of countries. Regional growth trails North America and East Asia because large-scale grid storage procurement mandates remain less developed across most European utility markets relative to leading US states.

Where Metal-Air Battery Margin Concentrates

Margin follows manufacturing scale and chemistry maturity, not universal cost advantage. Iron-air storage captures premium pricing for its unique duration profile, while primary cells compete on pure unit economics built over decades of steady, incremental manufacturing improvement across a small group of qualified global suppliers serving regulated medical device customers worldwide, year after year.

Long-Duration Storage Contracts Priced Against Alternatives

Iron-air developers price multi-year utility storage contracts against the levelised cost of alternative long-duration technologies rather than against short-duration lithium-ion, capturing a meaningful premium for the specific 100-hour discharge window few competing chemistries serve economically today. Form Energy's signed contracts with Great River Energy and other utilities reflect pricing built around avoided cost of alternative firming capacity, typically natural gas peaker plants, rather than a simple cost-per-kilowatt-hour comparison against batteries. This framing has supported contract pricing 20 to 30 percent above what pure battery-to-battery comparison would suggest, according to MMA Primary Research analysis of disclosed utility procurement filings.
Market Impact: Adds a 20 to 30% premium overall pr

Vertically Integrated Air Cathode Manufacturing Capacity

Manufacturers who vertically integrate air cathode production avoid dependence on external suppliers for a component that lacks the standardised global supply chain lithium-ion cathode materials now enjoy, capturing margin that would otherwise flow to a specialised third-party supplier. Form Energy and Panasonic Energy have both built in-house air cathode manufacturing specifically to control this bottleneck and protect proprietary catalyst formulations from competitor access. This integration has reduced per-unit cathode cost by an estimated 15 to 22 percent versus comparable external sourcing arrangements documented in company investor materials reviewed by MMA analysts.
Market Impact: Cuts cathode cost by 15 to 22% over

Medical Device Qualification Creates Switching Cost Lock-In

Hearing aid manufacturers rarely requalify battery suppliers once a zinc-air primary cell has passed device certification testing, since requalification requires repeating regulatory compliance work across every affected market and device model sold globally. Duracell and Panasonic Energy both benefit from this switching cost, retaining supply relationships worth an estimated 15 to 20 percent price premium with major hearing aid manufacturers across multiple product generations spanning a decade or more of continuous supply. This qualification lock-in supports stable pricing power in the primary cell segment even as raw material costs fluctuate considerably from year to year.
Market Impact: Locks in supply deals for 10-plus y

Government Demonstration Funding De-Risks Early Commercial Scale

Manufacturers securing government demonstration and research funding reach commercial manufacturing scale with meaningfully less private capital risk than competitors funding scale-up entirely through equity and debt markets under tighter repayment timelines and investor scrutiny. The US Department of Energy's Long Duration Storage Shot programme and comparable state-level grants have supported several iron-air and zinc-air developers through the capital-intensive transition from pilot to commercial-scale production. This funding has covered an estimated 10 to 18 percent of total scale-up capital for supported projects, according to disclosed grant award data reviewed by MMA analysts.
Market Impact: Covers 10 to 18% of total scale-up

Who Controls the Margin Pool

CR5 sits at 42 percent, moderate for an emerging energy storage category, reflecting the split between concentrated primary cell manufacturing and a still-fragmented grid-storage segment. Form Energy, Panasonic Energy, Duracell, Phinergy, and NantEnergy hold the top five positions, though each competes in largely different chemistry and application niches rather than head to head against one another for the same customers.
Current competitive activity centres on three fronts: iron-air developers racing to scale manufacturing ahead of utility procurement deadlines, primary cell manufacturers defending qualified hearing aid supply relationships against new entrants seeking market access, and aluminum-air developers in India pursuing cost-sensitive transportation applications that lithium-ion still serves rather poorly on price alone.

Emerging pressure comes from Chinese manufacturers, who have moved from limited primary cell production toward broader chemistry exploration across zinc-air and aluminum-air variants for domestic backup power markets and export opportunities across neighbouring countries and trading partners. Rankings shift most at the chemistry level rather than globally: a manufacturer's dominant position in zinc-air primary cells carries little weight in iron-air grid storage, where manufacturing scale-up speed and utility relationships reset the competitive order entirely each cycle.

Competitive Moat and Risk Dimensions

FORM ENERGY

Moat: Iron-Air Manufacturing Scale Lead

Form Energy operates the only commercial-scale iron-air manufacturing facility currently supplying signed utility contracts, giving it a multi-year lead over competitors still at pilot or demonstration scale in bringing the chemistry to full commercial production and delivery across multiple state grids and utility procurement pipelines nationwide.
FORM ENERGY

Risk: Single-Chemistry Manufacturing Bet

Form Energy's business depends almost entirely on iron-air commercial success, unlike diversified competitors, so any unexpected performance or cost issue at commercial scale would carry disproportionate consequences for the company relative to broader, more diversified rivals with multiple revenue streams and chemistry lines to fall back on.
PANASONIC ENERGY

Moat: Established Hearing Aid Supply Base

Panasonic Energy holds long-standing qualified supply relationships with major hearing aid manufacturers built over decades, a switching-cost advantage that new zinc-air entrants struggle to overcome given the regulatory cost of requalifying a medical device battery across every market and product line it currently serves worldwide.
PANASONIC ENERGY

Risk: Limited Grid Storage Exposure

Panasonic Energy's metal-air business remains concentrated in primary cells, leaving it under-exposed to the faster-growing grid-storage segment where iron-air and rechargeable zinc-air specialists are capturing the category's most significant near-term growth and investor attention across public equity markets worldwide this particular year of transition for the industry.

Zinc and Iron Powder Feedstock

Zinc and iron powder together represent roughly 29 percent of metal-air battery manufacturing COGS, sourced from a global base of metal powder producers including Höganäs AB and several Chinese and US suppliers serving both battery and traditional metallurgy end markets simultaneously across multiple industrial sectors and geographic regions worldwide, from Asia through the Americas and beyond.
Zinc price volatility during 2022 and 2023, driven by London Metal Exchange supply disruptions documented in LME market reports, pushed primary cell manufacturing costs up a cumulative 16 percent, forcing several hearing aid battery suppliers to renegotiate long-term customer pricing agreements mid-contract and absorb near-term margin compression. Iron powder pricing has remained comparatively stable given its far larger production base spanning steel and metallurgy industries well beyond battery applications specifically.

Exposure varies by chemistry. Iron-air manufacturers benefit from iron's abundant, geographically diverse supply base and correspondingly lower price volatility than zinc, while zinc-air primary cell manufacturers remain more exposed to LME zinc price swings that flow through to primary cell production costs within a single fiscal quarter given limited long-term supply contract coverage across the smaller manufacturer base still building scale.
metal-air-battery-market-cost-volatility-analysis-1787325625903

Long-Term Zinc Supply Agreements

Larger primary cell manufacturers now lock in multi-year zinc supply agreements with fixed volume commitments, insulating hearing aid battery pricing from short-term LME price swings that previously forced mid-contract customer renegotiations across the industry and delayed product roadmaps by multiple fiscal quarters at a time, straining relationships with long-standing medical device customers who expect price stability.

Iron Feedstock Diversification Across Suppliers

Iron-air manufacturers increasingly qualify multiple regional iron powder suppliers rather than depending on a single source, reducing exposure to any single supplier's production disruption as manufacturing scale-up accelerates demand for consistent material quality and delivery reliability across every active production line, a lesson learned from early supply-chain stress testing during initial ramp-up phases at the plant.

In-House Powder Processing Capability

Several leading manufacturers have built internal metal powder processing capability specifically to control particle size and purity critical to battery performance, trading higher fixed cost for consistent input quality that external suppliers cannot always reliably guarantee at scale across multiple production runs and shifting seasonal demand patterns observed year after year at every facility.

Portfolio Architecture for Margin Defence

Portfolio economics split across three tiers. Zinc-air primary cells compete mainly on unit cost and supply reliability in a mature, low-margin business built over decades of incremental refinement, while iron-air grid storage and specialised rechargeable applications command the highest margins, reflecting the technology premium buyers pay for capabilities lithium-ion cannot economically match at this specific discharge duration and operating scale.
The tension between volume and premium plays out starkly across the category. Primary cell manufacturers operate on thin, predictable margins built on decades of manufacturing efficiency and process refinement across a stable, well-understood supply base, while grid-storage developers price against avoided cost of alternative firming capacity rather than competing batteries directly, capturing considerably wider margins during this early phase of market development before broader competition fully arrives and gradually compresses pricing power.

High-value margin pools concentrate in long-duration grid storage during this early commercial phase, where limited competing supply keeps pricing power intact well past what the mature primary cell segment retains after decades of established, price-competitive manufacturing among a stable group of qualified global suppliers serving the same core customer base across multiple continents.

Volume / Commodity-Adjacent Tier

Zinc-air primary cells for hearing aids and medical devices, competing primarily on unit cost and supply reliability within a mature, established manufacturing base built over multiple decades of steady operation.
Gross Margin: 18%-26%

Premium / Certified Tier

Rechargeable zinc-air systems for backup power and behind-the-meter storage, commanding a premium where cycle-life limitations remain acceptable to buyers weighing total system cost against grid reliability, outage risk, and equipment downtime.
Gross Margin: 32%-42%

Sustainability / Regulatory / Next-Generation Tier

Iron-air long-duration grid storage priced against avoided firming capacity cost, capturing the category's widest margins during this early commercial phase of utility procurement, contracting, delivery scheduling, and long-term maintenance operations.

High-value Sub-segments and Strategic Watch-out

Utility-Scale Iron-Air Storage Contracts

Signed utility iron-air storage contracts combine high per-project value with the fastest specification growth in the category, as procurement solicitations naming long-duration storage as an eligible technology spread across additional states and utilities each passing year of active grid modernisation and expanding renewable capacity nationwide.
Gross Margin: 45%-55%

Indian Aluminum-Air Fleet Applications

Aluminum-air range-extension modules for Indian commercial electric fleets carry solid margins with a growth curve still several years behind grid storage, as fleet operators gradually validate unit economics against established lithium-ion alternatives already deployed at scale nationwide across multiple large delivery networks and dense urban service areas.
Gross Margin: 28%-38%

Established Hearing Aid Primary Cells

Long-established zinc-air hearing aid batteries generate steady, predictable volume across a mature patient base but carry thin margins after decades of price-competitive manufacturing among a small group of qualified medical device suppliers competing globally for the same certified, hard-won supply contracts renewed year after year.
Gross Margin: 18%-24%

Next-Generation Lithium-Air Research Programmes

Lithium-air batteries represent a strategic watch-out: theoretical energy density far exceeds lithium-ion, but it remains unclear whether catalyst degradation and cycle-life challenges can be solved economically at commercial manufacturing scale within this decade or perhaps even the one after that finally arrives in full commercial form.
Gross Margin: N/A pre-commercial

Contract Duration and Qualification Depth

Demand across the metal-air category splits into two very different economic patterns. Grid-storage contracts behave like long-term infrastructure agreements, with utilities signing multi-year commitments tied to specific discharge duration requirements, while primary cell sales behave like steady industrial supply relationships renewed year after year with minimal negotiation once a manufacturer clears initial device qualification testing.
Adoption depth varies considerably by application. Grid utilities move deliberately, running extended pilot and demonstration phases before committing to full commercial contracts, given the multi-decade asset life and reliability requirements involved in grid infrastructure decisions of this scale and consequence. Consumer and medical device applications show faster but narrower adoption, as manufacturers qualify a chemistry once and then rarely revisit that decision absent a significant cost or performance disruption.

A generational shift is underway in utility procurement teams. Planners who entered the profession after 2020 show meaningfully more willingness to evaluate emerging storage chemistries on a case-by-case duration and cost basis than predecessors trained purely on lithium-ion economics, a shift that should widen iron-air and other emerging chemistry adoption as this cohort gains seniority within utility planning organisations nationwide over the coming decade.

Positioning for the Storage Duration Shift

These are among the four positions where our research anticipates prominent divergence between winners and laggards over the coming forecast period. Each is grounded in the demand model, the regulatory perimeter, and the announced capacity pipeline.
01 / MANUFACTURING SCALE-UP TIMING

Reach commercial iron-air scale before utility patience runs out

Utilities that signed early iron-air contracts did so on the expectation of on-schedule commercial delivery, and any manufacturer that stumbles during scale-up risks losing the first-mover credibility that took years to establish with cautious utility procurement teams. Form Energy's West Virginia ramp sets the pace every other iron-air developer will be measured against going forward, fairly or not. Competitors entering later face a credibility gap that only a flawless first commercial deployment can close, based on how utility risk committees have evaluated comparable emerging technologies in the past.
02 / CHEMISTRY DIVERSIFICATION STRATEGY

Avoid betting the company on a single unproven chemistry

Single-chemistry manufacturers carry concentrated technology risk that diversified competitors with both mature and emerging product lines simply do not face to the same degree. Established players like Panasonic Energy and Duracell can fund iron-air or aluminum-air research from stable primary cell cash flow without betting the entire company on unproven commercial economics. Pure-play emerging chemistry developers face a narrower path: a single manufacturing or performance setback carries consequences that diversified competitors would absorb far more easily across their broader business.
03 / APPLICATION SEGMENT FOCUS

Match chemistry strengths to the application that actually needs them

Metal-air chemistries succeed commercially only when matched to applications that genuinely value their specific strengths rather than treating them as generic lithium-ion substitutes for every use case. Iron-air's 100-hour discharge window matters enormously to a utility firming renewable generation and not at all to a consumer electronics buyer. Manufacturers who chase broad market applicability instead of application-specific fit have historically struggled to build sustainable commercial traction, a pattern visible across multiple failed metal-air ventures over the past fifteen years of industry history.
04 / FEEDSTOCK COST RESILIENCE

Lock in zinc supply before the next LME price spike arrives

Zinc price volatility during 2022 and 2023 forced several primary cell manufacturers to renegotiate customer contracts mid-term, and the underlying LME supply dynamics that caused that volatility have not meaningfully changed since. Manufacturers still buying zinc on short-term contracts remain exposed to the same risk as global metal markets tighten during the next demand cycle. Long-term supply agreements have already proven their value for manufacturers who adopted them ahead of the 2022 price spike, a lesson worth applying before the next one arrives.

MARKET MINDS ADVISORY · CLIENT ENGAGEMENT SUMMARY
Metal Air Battery Producer Strategic Portfolio Review and Transition Roadmap 2026·Investment Scenario on Metal Air Battery Exposure Evaluation 2025-26
CLIENT PROFILE
The client is a rural electric cooperative serving roughly 140,000 members across the upper Midwest, with annual capital budget reported in the 60 to 90 million dollar range (client-reported, unverified by MMA), evaluating long-duration storage options to firm a growing share of wind generation on its system as older fossil generation capacity retires across its territory.
STRATEGIC CHALLENGE
The cooperative had never procured storage beyond short-duration lithium-ion peaking capacity and faced a choice between waiting for iron-air technology to prove out further at other utilities or moving early to secure capacity and pricing ahead of an expected wave of broader utility demand entering the same manufacturer supply queue.
MMA APPROACH
MMA benchmarked the cooperative's renewable integration needs against comparable rural utility deployments already underway, analysing discharge duration requirements and levelised cost across iron-air, lithium-ion, and flow battery alternatives available today. The team conducted primary interviews with utility planners at two cooperatives that had already signed iron-air supply agreements ahead of the client's own decision.
KEY FINDINGS
  1. Iron-air storage priced roughly 25 percent below the levelised cost of equivalent lithium-ion capacity at the cooperative's required 80-hour discharge duration overall.
  2. Early-mover cooperatives that signed contracts before 2025 secured meaningfully better delivery scheduling than utilities entering the same manufacturer supply queue only afterward.
  3. Flow battery alternatives offered comparable duration but carried higher disclosed capital cost per megawatt-hour across every benchmarked comparable project the team reviewed.
  4. Wind curtailment on the cooperative's system had already reached 8 percent of available generation, a cost largely avoidable through added storage capacity.

  1. Iron-air storage priced roughly 25 percent below the levelised cost of equivalent lithium-ion capacity at the cooperative's required 80-hour discharge duration overall.
  2. Early-mover cooperatives that signed contracts before 2025 secured meaningfully better delivery scheduling than utilities entering the same manufacturer supply queue only afterward.
  3. Flow battery alternatives offered comparable duration but carried higher disclosed capital cost per megawatt-hour across every benchmarked comparable project the team reviewed.
  4. Wind curtailment on the cooperative's system had already reached 8 percent of available generation, a cost largely avoidable through added storage capacity.
RECOMMENDED STRATEGY
Phase 1: Phase 1 (Months 1 to 4): Finalise discharge duration and capacity requirements based on wind curtailment and system load analysis. Phase 2: Phase 2 (Months 5 to 10): Negotiate an early-mover supply agreement to secure favourable delivery scheduling ahead of rising demand. Phase 3: Phase 3 (Months 11 to 24): Commission the storage facility and integrate operations with existing wind generation dispatch and control systems.
OUTCOME
The cooperative signed a supply agreement securing delivery eighteen months ahead of utilities entering procurement in 2026, at pricing roughly 12 percent below the levelised cost benchmark identified during the engagement (client-reported, unverified by MMA). Projected wind curtailment reduction reached an estimated 6 percentage points once the facility reaches full commercial operation.
