Home / Australia guides / Essential household services / Food refrigeration planning: Farm residence
Australia planning guidance for a specific property and load boundary. Separate household water from production pumping. H2OME remains in early development.
Refrigeration demand varies with cabinet size, door openings, loading and room conditions. The electric supply is only one part of food protection; temperature records, safe handling and a decision about disposal remain important when operation has been interrupted. Measure each appliance rather than assuming two refrigerators use the same energy.
Do not convert a calculated electrical duration into a food-safety promise. A cabinet may have warmed before supply was restored, or its compressor may fail to start. Keep a temperature-check and food-handling plan separate from the power-system worksheet.
Milking plant, large refrigeration, irrigation and workshop machinery need a separately engineered supply assessment.
The residence may sit beside machinery that exceeds a small household system. Domestic continuity and farm production must be separate scopes; sharing a driveway does not make a large shed a household load.
In a farm residence, confirm whether domestic refrigeration already includes the proposed second refrigerator. The extra 1.08 kWh belongs in the worksheet only if it represents a genuinely separate cabinet; record the temperature-check responsibility as well as the electrical demand.
Separate household water from production pumping. H2OME has a 10 kW design target, not a demonstrated farm power rating. Large production loads may be outside its scope entirely; no multi-unit capability is assumed here.
All numbers below are hypothetical teaching inputs, not measured appliance specifications or product performance. The topic-specific extra load is separate from the base set; omit it if your real inventory already counts it. This worksheet does not include conversion overhead, protection design or a contingency allowance.
For a farm residence, assume the selected base loads average 0.32 kW for 18 hours: 0.32 × 18 = 5.76 kWh. Separately, a second refrigerator, additional to the base set draws an assumed 90 W for 12 hours: (90 ÷ 1,000) × 12 = 1.08 kWh. The combined illustrative demand is 6.84 kWh.
This assumes a time-averaged input and does not establish safe food temperature.
For arithmetic only, if the complete storage chain had a hypothetical 30% round-trip efficiency, delivering 6.84 kWh would require 6.84 ÷ 0.30 = 22.8 kWh of charging input. This is not a measured H2OME efficiency or recovery result. Ongoing demand during charging would add to the required input.
Base operating window: 18 hours. Extra illustrative load: A second refrigerator, additional to the base set, 90 W for 12 hours. Replace every input with a measured or professionally established value.
In Australia, check connection questions with your electricity retailer and distributor. Use electrical professionals holding the licence required in your state or territory, and ask the local council about relevant siting, building and water-use requirements. Energy Made Easy covers New South Wales, Queensland, South Australia, Tasmania and the Australian Capital Territory; outside those jurisdictions, check the relevant state or territory consumer energy comparison resource. Compare your actual tariff and charging window, not an assumed national rate. This guide does not claim to know a particular state's approval process.
For life support equipment in Australia, keep life support registration current with the electricity retailer or distributor as applicable and confirm how the other party is notified. Follow your clinician and equipment provider's contingency plan. Registration is not a guarantee of continuous electricity, and H2OME cannot replace an independent medical contingency.
H2OME is in early development. Its 10 kW output figure is a design target, not a proven specification. There is no confirmed price, certification, commercial availability or guaranteed runtime in this guide.
Hydrogen is an energy store, not free energy. Grid input, wind and micro-hydro are the charging options considered here. Each requires its own supply assessment. Do not install hydrogen equipment, modify fixed wiring, bypass protection or improvise a connection from this guide.
These official resources provide energy, consumer and technical background. They are not endorsements of H2OME, proof of its performance or a substitute for site-specific professional advice.

No. The 6.84 kWh total is an illustrative demand worksheet, not a runtime result. Actual appliance measurements, usable storage output, starting demand, conversion overhead and reserve limits are needed. The 10 kW design target is not demonstrated output capability.

Ask us about H2OME, tell us about your property or register your interest in the proposed system. We are in early development. No payment or purchase commitment; contacting us does not guarantee a pilot installation.
