JUST WONDERING
I was looking at Marinovich and the math kept coming out the same way it did for Lineage across town. Hover the toggle — same nine blast tunnels, same crews, same docks; just the thing inside the engine room changes. And the four numbers around the diagram.
AS ISexisting NH₃ central plant
TO BEReChill distributed CO₂ fleet
What's there nowCentral NH₃ rack feeding nine blast tunnels and the cooler zones. Continuous-duty screw compressors at part load with hot-gas bypass. CalARP filing, contract RETA operator coverage, annual inspections.
What ReChill would put there3 × C40 distributed across the warehouse zones + 1 × C20 for blast tunnel staging. Variable-speed CO₂ throughout. Hot-swap battery cartridges. Zero NH₃ on site.

The thing that made me sit down and run this
The same thing that makes a Tesla go 0-60 in 2 seconds — high-power-density
variable-speed electric drive, automotive-grade battery, precision motor control — makes
your plant save millions and never touch ammonia again.
Same drivetrain. Different package. Sitting at auction for $7K a copy.

Marinovich on ReChill. NH₃ off and sold for scrap. Packs auctioned. Nobody loses a shift.
Why nobody's noticed yet
Every refrigeration engineer in the valley grew up sizing bigger NH₃ racks. When a family operator at 200 TR says 'what do we do at this scale,' the answer is always 'rebuild the rack' — three-month outage, $2-3M, same compressor brands, another decade of CalARP filings. Meanwhile there are Tesla packs at Manheim for $7K each, three hours from the Watsonville dock. The hardware to wrap one in a container with a Bitzer CO₂ head is commodity. It just hasn't occurred to anyone yet.
The line I keep saying out loud when I run the numbers
The same drivetrain that takes a 4,500-lb sedan from 0 to 60 in two seconds — the 75 kW continuous IPMSynRM motor, the 400 V battery, the variable-speed inverter — is sitting at salvage auction. Put it in a container with a CO₂ head and it runs your blast tunnels at part load without hot-gas bypass and without a single pound of anhydrous ammonia on the floor. That's it. That's the whole thing.
Be brutal with my numbers — it's still wild
Cut my load estimate in half, savings drop to ~$125K/yr · cut my $/kWh to $0.10, $170K/yr · cut the off-peak shift to zero, $190K/yr · push install to 12 months, NPV still pencils. The exact number doesn't matter. The thing I keep getting stuck on is that nobody's even sketching this for a Watsonville family operator — there's a Tesla pack three hours from the dock and you've been running blast tunnels for 80 years.
