Emerging Trends

Metal–air (air-electrode) batteries are moving into food cold-chains

A clear trend is the use of zinc-air and aluminum-air batteries to keep food cold-chains running when the grid is weak or diesel is costly. Why this matters is simple: too much food is lost before it reaches people. FAO’s latest SDG 12.3.1a update estimates 13.3% of food is lost after harvest, in transport, storage, processing and wholesale (2023). Cutting those losses needs reliable cold storage close to farms.

Waste at the consumer end is also huge. The UNEP Food Waste Index 2024 reports 1.05 billion tonnes of food wasted in 2022, equal to 132 kg per person, with households causing 60% of that waste. Cooling, better last-mile logistics and steadier power supply help here too, especially for perishables.

Air-electrode batteries fit this gap. They have high specific energy and simple architecture: oxygen from the air reacts at the cathode, so the pack carries less inactive mass. In farm cool-rooms and reefer micro-hubs, zinc-air modules can act as long-duration backup for solar-plus-storage systems, keeping compressors running overnight without diesel. They can also be “refueled” or swapped in modular cassettes, a practical advantage for small operators.

The direction of travel is supported by the broader storage build-out: in the IEA Net-Zero Scenario, grid-scale battery capacity must expand ~35-fold to nearly 970 GW by 2030—a signal to suppliers to scale safer, low-cost chemistries, including metal-air variants tailored for stationary use.

Drivers

Decarbonizing and securing food cold-chains with high-energy air-electrode batteries

A powerful, near-term demand driver for air-electrode batteries is the need to decarbonize and stabilize refrigeration across food cold-chains and agro-processing. Food agencies flag the scale of the problem: the UN Food and Agriculture Organization (FAO) reports that about 14% of global food is lost between harvest and retail, worth roughly US$400 billion each year—much of it tied to weak storage and logistics. UNEP and FAO add that ineffective refrigeration alone accounted for the loss of ~12% of total food production (2017), while the food cold-chain contributes ~4% of global greenhouse-gas emissions when both equipment and loss-related emissions are counted.

Air-electrode batteries—such as metal-air variants—prioritize energy per kilogram by leveraging oxygen from air as the cathodic reactant. Their high specific energy makes them attractive for long outages and remote nodes where diesel backup is costly and polluting. The IEA underscores the systemic pull: grid-scale storage is “essential” to keep variable renewables stable as electricity demand rises, and EV-driven learning is rapidly scaling battery manufacturing (EV battery deployment +40% in 2023).

Public policy is now targeting the long-duration segment where air-electrode chemistries could shine. California has allocated over US$270 million specifically for non-lithium long-duration energy storage (LDES), and has issued large project grants—including US$30 million for a 100-hour system—to diversify beyond conventional chemistries. At the federal level, the U.S. Department of Energy has opened calls of up to US$100 million for non-lithium LDES pilots capable of ≥10-hour discharge—programs that can help de-risk metal-air designs in real cold-chain and agro-processing use cases.

In the U.S., battery build-out shows what scale can deliver. California has installed ~8.6 GW of battery capacity, at times supplying up to 20% of peak power; this grid experience lowers integration barriers for advanced chemistries aimed at industrial loads like refrigeration.

Restraints

Air-Management And Durability Penalties in Real Cold-Chain Environments

A major constraint on air-electrode batteries (e.g., metal-air) is the cost and complexity of managing real-world air in food cold-chains—where carbon dioxide, moisture, and organics are routinely elevated. Lithium-air cells are highly sensitive to ambient CO₂/H₂O; CO₂ reacts to form lithium carbonate at the air electrode, a by-product widely recognized to hinder reversibility and cycle life. Preventing this requires scrubbers, filters, or membranes, adding balance-of-plant cost and maintenance that offset energy-density benefits. Peer-reviewed studies explicitly link CO₂ ingress to parasitic carbonate formation and degraded cycling in Li-air systems.

Food facilities regularly run with CO₂ levels far above ambient. Controlled-atmosphere (CA) cold stores for produce operate with ~1–5% CO₂ and ~1–5% O₂, versus normal air at ~0.03% CO₂—conditions intentionally maintained for quality but hostile to an unprotected air cathode. Banana ripening rooms must keep CO₂ below ~1%, yet CO₂ spikes are common during climacteric respiration, forcing active venting and monitoring; guidance from Indian horticulture agencies specifies CO₂ sensing and ventilation controls for proper ripening.

Grid reliability compounds the restraint. Food processors in many emerging markets face frequent outages, driving a preference for proven diesel backup and creating a high bar for any new battery. World Bank Enterprise Survey data show the share of firms experiencing electrical outages is persistently high; in Nigeria, historical values reached 95.6% (2007) and 77.6% (2014) of firms reporting outages.

Paradoxically, the climate case for cleaner backup is strong: about 4% of global GHG emissions are tied to the food cold-chain when both refrigeration and spoilage are counted, so the sector needs scalable, low-emission storage. Yet these same facilities’ elevated CO₂/RH environments raise integration costs for air-electrode batteries today. Industry and policy are trying to close the gap—California’s Long-Duration Energy Storage program has allocated >US$270 million for non-lithium demonstrations, including a US$30 million grant for a 100-hour project to validate long-autonomy storage and derisk new designs.

Opportunity

Powering Resilient, Low-Carbon Food Cold-Chains with Air-Electrode Storage

Air-electrode batteries have a clear commercial opening wherever food systems need long-autonomy, low-cost backup and renewable shifting. The scale of the prize is large and well quantified by food bodies. The UN Food and Agriculture Organization estimates around 14% of the world’s food is lost between harvest and retail, equal to about US$400 billion per year—a loss profile concentrated in storage, handling and transport where dependable power matters most.

UNEP and FAO further report that the food cold-chain accounts for ~4% of global greenhouse-gas emissions when equipment and loss-related emissions are combined, so cutting cold-chain diesel use and spoilage delivers immediate climate dividends.

Independent coverage of IEA’s analysis adds a system-level marker: meeting the COP28 goal to triple renewables requires about 1,500 GW of energy storage by 2030—a ~15× increase from current levels—creating headroom for diverse chemistries, including air-electrode batteries optimized for long duration.

Policy is lining up capital for demonstrations that food operators can leverage. California’s Long-Duration Energy Storage (LDES) program approved a US$30 million grant for a 5 MW/500 MWh (100-hour) project—evidence that regulators are paying for multi-day storage to ride through extreme weather and outages.

In India, where farm-to-fork electrification is expanding quickly, the Ministry of Food Processing Industries reports ₹8,853 crore in approved grants under PMKSY across 1,601 projects, with new cold-chain interventions explicitly prioritized—an investment pipeline that can specify clean, long-duration backup in tender documents.
