Home / New Zealand guides / Household decisions / Preparing for an early-development pilot: Lifestyle block
New Zealand planning guidance for a specific property and load boundary. Compare essential supply with whole-property ambitions. H2OME remains in early development.
H2OME is in early development. A useful expression of interest includes the site type, a measured load inventory, access constraints and the reason for seeking backup. It is not an order for available equipment and should not displace an existing contingency plan.
The 10 kW figure is a design target, not a proven specification. Any pilot needs a defined scope, professional safety review, acceptance criteria and responsibilities. Ask what is being tested, which functions remain unproven and how the property returns to its previous arrangement if the trial ends.
Irrigation, power tools and nonessential shed equipment should have separate operating windows.
A modest house can share a supply with a bore, shed, stock-water pump and powered gate. A meter total alone hides which remote circuit starts first and which load is necessary for people or animals.
Provide the 3.96 kWh base worksheet for a lifestyle block as an assumption to verify, not a requirement the prototype is already known to meet. Keep the extra test logger's consumption separate from the real appliance scope and retain the existing outage fallback.
Compare essential supply with whole-property ambitions. A pump average does not describe its starting demand. Long cable runs and water-system controls also need professional review before a load is included.
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 lifestyle block, assume the selected base loads average 0.33 kW for 12 hours: 0.33 × 12 = 3.96 kWh. Separately, an additional test logging device draws an assumed 20 W for 6 hours: (20 ÷ 1,000) × 6 = 0.12 kWh. The combined illustrative demand is 4.08 kWh.
Test instrumentation also consumes energy and must be separated from ordinary appliance demand.
For arithmetic only, if the complete storage chain had a hypothetical 30% round-trip efficiency, delivering 4.08 kWh would require 4.08 ÷ 0.30 = 13.6 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: 12 hours. Extra illustrative load: An additional test logging device, 20 W for 6 hours. Replace every input with a measured or professionally established value.
In New Zealand, discuss supply arrangements and connection questions with your electricity retailer and distributor. Ask the local council about relevant siting, building and water-use requirements. Use appropriately qualified electrical and hydrogen professionals, and refer workplace safety questions to WorkSafe guidance. This page does not establish a consent or compliance outcome.
For medically dependent people in New Zealand, register with your electricity retailer, the company that bills you, and keep that registration current. Re-register when switching retailers; ask the retailer how the distributor is informed and what clinical confirmation is needed. Follow the clinician and equipment provider's contingency plan. Registration does not guarantee uninterrupted electricity, and H2OME is not a substitute for that plan.
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 4.08 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.

Use the worksheet to brief the relevant professionals, not to install, modify or operate hydrogen equipment.
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.
