Keeping a country medical centre open in an outage

When the power goes out in a rural district, the local clinic is often still needed. This page covers the loads a hydrogen system could support, and its limits.

What a small clinic actually runs

A two or three room rural practice runs vaccine fridges, a patient management system on a local server or over the internet, the phone system, an autoclave for instruments, examination lights and heating. Most of those are small and steady. The autoclave and any hot water cylinder are the larger draws. Together they generally sit inside a 15 kW system's continuous output, with peak headroom for start-ups.

What it would keep running

  • Vaccine fridges and data loggers
  • Patient records and phone system
  • Instrument autoclave
  • Examination and waiting room lighting
  • Heat pumps in consult rooms

Instant, so nothing reboots mid consult

With the battery and inverter in UPS mode, a GP mid way through notes does not lose them, and the phones keep ringing. The fuel cell then carries the clinic from stored hydrogen, with no generator to start and no exhaust near the waiting room.

Hydrogen is stored at 30 bar or less with redundant leak sensors and automatic venting, and the unit would sit outdoors, away from patient areas and the car park. In a district outage, a clinic that keeps its doors open also takes pressure off ambulances and the nearest hospital.

How it works →
The H2OME loop: an electrolyser splits water into hydrogen, the hydrogen is stored in a tank for weeks, a fuel cell turns it into electricity for your home, and the water returns to the loop.

What it is not

This is building backup designed to AS/NZS 60079 and ISO 19880, not a hospital-grade supply and not a substitute for a clinic's own continuity plan. Patients who rely on powered equipment at home should keep their power company's medically dependent registration and talk to their clinician about their own plan. Round trip is 30% or less, so running it is dearer than the grid.

Questions

Could it run a clinic's emergency equipment?

It could keep the building's circuits powered, but it is not a hospital-grade supply. Critical equipment should have its own internal batteries and the clinic should follow its own clinical guidance. We would never present this as the only safeguard.

What about patients on home oxygen?

This system is for the clinic building. Patients relying on powered equipment at home should keep their power company's medically dependent registration and talk with their clinician about backup options for their own homes.

Does it need much attention from staff?

It has no engine, needs no fuel deliveries, and shuts down and vents automatically if a sensor detects a problem. Pilot sites would agree a maintenance arrangement before installation, so clinic staff are not expected to look after it.
