AI has a heat problem. PhaseShift turns it into food and energy.
A two-phase ammonia cooling system for the densest GPU infrastructure ever built, designed to use zero water for evaporative cooling, run on renewables, and feed its byproducts to farms instead of the atmosphere.

THE PROBLEM
Compute is outrunning cooling.
Data centers drew 415 terawatt-hours in 2024. By 2030 the IEA projects 945, more electricity than Japan uses today. [I]
The racks driving that curve are getting hotter, faster. An NVIDIA Hopper rack drew about 40 kW. Blackwell reached 130. Vera Rubin systems shipping this year draw over 200 kW per rack, and the 2027 Kyber racks are specified at 600 kW, with megawatt-class racks already on the roadmap. [I]
Today’s answer is to spray water at the problem. A single large data center can consume five million gallons a day, as much as a town of 50,000 people. In Texas alone, data centers are projected to grow from 49 billion gallons in 2025 to as much as 399 billion by 2030. [I]
Single-phase water cooling is running out of physics. The industry needs a working fluid that can absorb 600 kW in a rack footprint, without drinking the town dry.
HOW PHASESHIFT WORKS
Change the phase, not the planet.
PhaseShift replaces single-phase water loops with two-phase ammonia, the same working fluid that has run industrial refrigeration safely for over 150 years, re-engineered for the GPU die.
01
Boil at the chip.
Liquid ammonia enters microchannel cold plates mounted directly on each GPU. In margin mode (about 10 bar) it boils at just 24.9°C, absorbing 1,166 kJ for every kilogram that changes phase, an order of magnitude more heat per kilogram than warming water can carry. [M]
02
Ride the vapor.
Phase change does the work. Vapor carries the heat out of the rack through compact manifolds, less pumping power, less plumbing, less parasitic load.
03
Condense and recover.
A silicon-carbide condenser returns the vapor to liquid. In harvest mode (15-17 bar), the heat hands off to a 30-40°C facility water loop, a temperature that greenhouses, aquaculture, and process pre-heat can actually use. [M]
04
Seal and repeat.
The loop is closed. Modeled makeup is 70-140 kg of ammonia per year, a refrigerant top-off, not a consumable. [M]
No evaporation. No fluorinated fluids. No forever chemicals. One loop, sealed, doing the same job for decades, the way ammonia already does in cold storage across the world. And one dial: the same loop runs in margin mode (about 10 bar) for maximum chip headroom or harvest mode (15-17 bar) for greenhouse-grade heat, and reaches 3,600 W GPUs with the same pressure adjustment. [M]
WATER
Cooling that doesn’t drink.
Most data center cooling works like sweating: pull in water, evaporate it, lose it. Across Google’s fleet in 2024, 78% of the water withdrawn never came back, it left as vapor. [I]
PhaseShift is sealed by design. The working fluid changes phase inside the loop, not into the sky. Design target: zero evaporative water consumption at the cooling system. [M]
The water story doesn’t stop at the fence line. Every kilowatt-hour pulled from a thermal grid carries roughly 1.2 gallons of embedded cooling water at the power plant. [I] PhaseShift facilities are designed to pair with dedicated solar, wind, and storage, cutting the hidden water bill along with the visible one.

Compute in. Food and energy out.
Every cooling system moves heat. PhaseShift is designed to move it somewhere useful, and its working fluid happens to be the most important agricultural chemical on Earth.

PhaseShift campuses are designed around renewable-powered ammonia synthesis: electrolysis splits water with solar and wind, nitrogen comes from the air, and a modular Haber-Bosch unit produces green ammonia on site. The loop’s refrigerant supply chain is a pipe from next door, and renewable power carries near-zero embedded water versus ~1.2 gallons per kWh from thermal grids. [I]
The refrigerant is the fertilizer.
Ammonia is the backbone of world agriculture, US farms consume tens of millions of tons a year. A single PhaseShift SuperPod’s integrated synthesis is modeled at 411 tons of green ammonia annually; a 25-pod campus exceeds 10,000 tons, a real commercial supply for regional growers. [M] And the market is moving our way: US anhydrous ammonia averages $976-1,036 per ton in July 2026 USDA and DTN surveys, green ammonia commands a growing premium, and the green ammonia market is projected to grow from $662M in 2024 to $38.5B by 2033. [I]
Heat that grows things.
In harvest mode, PhaseShift rejects heat at 30-40°C, exactly the grade greenhouses and aquaculture want. The precedent is already live: data center heat warms lobster and trout farms in Norway, eel farms in Japan, and greenhouses from Sweden to Ohio. Just 200 kW of recovered heat can warm a full hectare of greenhouse, enough for roughly 88,000 pounds of tomatoes a month. A PhaseShift campus rejects megawatts. [I]
This is the loop we’re building partners around: renewables power the compute, the compute’s byproducts feed the farm, and nothing of value leaves as vapor.

SAFETY & STANDARDS
Proven chemistry, modern engineering.
Ammonia is not exotic. It has cooled the world’s food supply for over 150 years, governed by a mature body of standards, ASHRAE 15, IIAR 2-9, OSHA PSM, EPA RMP, ASME BPVC, that PhaseShift is engineered against from day one, including voluntary process-safety practices below regulatory thresholds.
It’s also self-announcing: the human nose detects ammonia at 5 parts per million, far below hazardous levels, making it one of the few refrigerants that reports its own leaks. Zero ozone depletion. Zero global warming potential. No PFAS. And a genuine whitespace: only about 2% of data center cooling patents specify two-phase operation. PhaseShift’s provisional patent stakes that ground.
