A home kill chiller that stays cold when the lines drop

Once a beast is killed, the carcass has to cool and hang at the right temperature. An outage in the first day or two is the worst timing there is.

Why the first days matter

Home kill on a farm usually means a carcass hung in a walk-in chiller to cool and set, then held for days while it ages before being broken down into cuts. The chiller has to pull heat out of a warm carcass quickly at first, then hold steady. A warm spell in a chiller lets bacteria grow and spoils meat that the family was counting on for months. Many farm chillers are small walk-in rooms with a single condensing unit, sitting in a shed beside the house.

What it would keep running

  • Walk-in chiller condensing unit
  • Evaporator fan
  • Chest freezers
  • Temperature logger
  • Shed lighting for breaking down

How the system keeps it running

Hydrogen is made on off-peak power overnight and held at 30 bar or less for weeks. When the grid fails, the UPS-mode inverter takes over instantly, the battery covers the compressor start, and the fuel cell keeps the battery charged as the compressor cycles. The chiller's thermostat carries on as normal, and the temperature log stays unbroken.

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.

Fit and honest limits

A small walk-in chiller and a freezer or two sit well within 15 kW continuous, with room left over for the house. Larger commercial chillers, like those at a licensed abattoir or a busy contractor, would need a larger or multi-unit setup sized in the pilot. Round-trip efficiency is 30% or less, so this is about protecting meat through outages rather than running cold storage more cheaply. Food safety rules for home kill remain yours to follow.

Questions

Can it run the chiller and the house together?

Usually yes. A small chiller and freezers sit comfortably within 15 kW alongside an average home. The pilot would check the combined peak if you also run heavy appliances like an oven and heat pump together.

What if I kill in summer?

A chiller works harder in summer, especially pulling down a fresh carcass. That is still within range for a small walk-in room. The pilot would log a summer load to size the hydrogen store properly.

Can it cover a licensed abattoir chiller?

One unit is unlikely to. Commercial chillers draw much more. A larger or multi-unit setup could be sized in the pilot, but for some plants this is simply not the right fit.
