On farms and stations where hunters operate, carcasses are often hung in a walk-in chiller near the woolshed or yards until they are collected by a game processor or broken down. The chiller may sit at the end of a long farm track, with the farmer checking it only every day or two. It is usually a simple insulated room with one condensing unit, and the season can run for months.
An outage after a good night's hunting means a full chiller and a warming room, often unnoticed until the next visit. By then the meat may be fit only for the dogs, and the hunters' effort is gone with it.
Hydrogen is made on off-peak power, or from wind or micro-hydro at a remote site, and stored at 30 bar or less for weeks. When the grid drops, the inverter switches over instantly, so the chiller compressor and controller carry on without restarting. The battery covers compressor starts, and the fuel cell keeps the battery charged as the chiller cycles through the night.
How it works →
A small walk-in chiller sits comfortably within 15 kW continuous, with room to spare for lights and a wash-down pump. At an off-grid hut or outstation, the system can be paired with a wind turbine or micro-hydro to make its own hydrogen. Processor collection rules and food safety requirements stay with you and the processor. Round-trip efficiency is 30% or less, so this protects carcasses in outages rather than cutting cooling costs.
Yes, if there is wind or micro-hydro to make the hydrogen. Without either, it needs grid power to charge. A remote chiller with a good stream nearby is a natural fit for micro-hydro charging, subject to a pilot site check.
A temperature alarm on the backed-up supply keeps working through the outage. Whether it can reach your phone depends on mobile coverage at the site and how the alarm is set up.
That is between you and the processor. The system is designed to keep the chiller running through outages, but it does not change any rules about chilling, holding or collection.
