Cooling needs are rising fast, and ice sits at the center of it. With the IEA estimating cooling at about 7% of global electricity demand today, the question is no longer whether refrigeration can scale, but how ice quality, sanitation, and energy efficiency hold up across the full cold chain. From hydropower supplying 5.1% of global primary energy demand to 57% of cold chain food losses happening at storage, the dataset links energy, safety rules, and performance in ways you might not expect.
Key Takeaways
- 5.1% of global primary energy demand came from hydropower in 2022, demonstrating that renewable electrification can scale beyond wind/solar alone
- 1.5% of global final energy demand came from hydropower in 2022
- 41.0% of global electricity generation in 2022 came from low-carbon sources (renewables + nuclear), supporting large-scale demand for power-sector cooling and related systems
- Ice used for human health and food safety purposes is regulated in many jurisdictions; in the EU, food-contact materials are subject to Reg. (EC) No 1935/2004 safety requirements
- EU hygiene rules for food include temperature control requirements relevant to ice used as an ingredient or processing aid (Regulation (EC) No 852/2004)
- In the U.S., FDA Food Code defines sanitation and operational controls for food establishments, including ice-making processes as part of food handling requirements
- Cold chain quality is often tracked using temperature logging; maintaining the correct temperature reduces spoilage and improves food safety outcomes
- A 2019 meta-analysis reported that refrigeration/temperature control interventions reduce foodborne illness risk (directionally supporting ice-related cold-chain quality control)
- For cold-chain logistics, a 2016 study estimated that temperature excursions can increase costs due to waste and spoilage for perishable foods
- Vapor-compression refrigeration efficiency is often reported as EER or COP; improved heat-exchanger and control strategies can increase COP in ice machines (quantified across studies)
- In published studies of ice-phosphating and brine freezing systems, improvements in heat transfer can increase freezing rate by measurable percentages (reported in experimental papers)
- Freezing efficiency depends on brine/air temperature difference; increasing the temperature difference can reduce freezing time measured in minutes
- The global seafood cold chain is estimated at over $300 billion, supporting demand for ice (traditional and manufactured) in fisheries supply chains
- Marine fisheries worldwide report billions of tons of landings annually; ice is a primary preservation method for many landing operations (quantified landings in FAO data)
- FAO reports that global capture fisheries landings were about 90 million tonnes annually in the most recent years of reporting, creating large volumes requiring preservation (often including ice)
Hydropower and better temperature control underpin cold chains, driving rising ice demand as freezing food waste persists.

COP (coefficient of performance) of vapor-compression systems typically varies with condensing temperature; for every 1°C increase in condensing temperature, energy consumption increases roughly 1–2% in vapor-compression refrigeration, impacting ice production operating cost.https://www.iea.org/reports/the-future-of-cooling?mode=download
06
For many frozen-food cold chains, each 1°C increase in average storage temperature can increase spoilage rates (and corresponding losses) by roughly 2–3% per year depending on product type and conditions.https://www.sciencedirect.com/science/article/abs/pii/S0306919220301730
Interpretation
Performance Metrics Interpretation
In performance metrics for ice production and storage, small efficiency and temperature shifts matter a lot because better heat transfer and control can measurably raise COP and freezing rates while each 1°C increase in condensing temperature typically raises energy use by about 1 to 2 percent and each 1°C higher storage temperature can drive spoilage up roughly 2 to 3 percent per year.
