Site energy as recoverable heat

AgriTechTonic integrates a data centre, grow module, and energy hub. Waste heat at 50 to 70 degrees Celsius flows from the data centre into the grow module. Solar, wind, and a heat pump feed the energy hub, which dispatches renewable energy to the grow module and the data centre.

One stack. Three industries that finally talk.

AgriTechTonic is modular, containerised infrastructure that turns data centre waste heat into food at zero heating cost. Each node combines an edge data centre, a controlled-environment grow module, and a renewable energy hub into one deployable stack, operated by Gravitonic Ltd.

The problem

Heat dumped. Farms billed. Grid queued.

Data centres waste heat; farms pay to stay warm; the grid cannot keep up. None of them are designed as a single system.

  • Waste heat to atmosphere — conventional halls vent recoverable thermal output instead of using it.
  • CEA heating as dominant opex — UK grow rooms buy warmth from the grid or from combustion.
  • Fragile central plants — compute, cold chain, and power sit far from the communities that depend on them.
Industries connectedNone, today
The solution

Pipe the heat. Containerise the rest.

A 500 kW data centre produces 100–150 kW of continuous thermal output. A grow container needs constant warmth. We close that loop on site.

  • Direct liquid cooling — 50–70°C exhaust matches the temperature CEA heating needs.
  • Zero marginal heating cost — recoverable heat is piped into the adjacent grow module.
  • Solar, wind, LFP, grid fallback — the energy hub can island if the public network drops.

The conditions for this have never been better aligned.

Four UK conditions now make this stack practical to deploy.

Modular data centre demand

Industry analysis puts global modular data-centre market growth at around 17% CAGR through the late 2020s. Edge compute and AI inference need capacity that can be placed quickly and locally. Traditional construction cannot match that speed, which is why prefabricated halls are moving from niche to default for distributed loads.

UK food security

The UK produces approximately 60% of the food it consumes by value. Defra’s 2024 food-security report recorded a 62% production-to-supply ratio for all food in 2023, with a stable ~60:40 domestic-to-import balance. Food security is now a funded policy priority across Innovate UK, DEFRA, and UKRI.

DLC is now mainstream

Direct liquid cooling from vendors including HPE and Danfoss is commercially available off the shelf. The 50–70°C exhaust it produces sits in the temperature range CEA heating needs. That match is an engineering fact, not a future research programme.

Grid constraints

Long connection queues and rising demand are making off-grid and edge-sited infrastructure more attractive to operators and landowners. A node that can island, export under the Smart Export Guarantee, and still fall back to the grid is a practical response to that constraint — not a slogan about leaving the network.

Where a node sits

Farms, estates, and edge compute sites

The same three containers adapt to unused rural land, capacity-constrained IT operators, and places where the grid queue is the constraint.

If you have a pad, a grid connection, or an existing renewable plant, a node can sit beside it without a multi-year data-hall programme.

Island-mode food, compute, and power

Island-mode capableSEG and DSR ready
Distributed resilience

Every community deserves its own infrastructure.

Each AgriTechTonic node is island-mode capable. It produces food, processes compute workloads, and generates energy locally. A failure in any other node has zero effect on it. That is the opposite of a system in which one regional outage, one cold-chain breach, or one airline IT fault can halt activity across a continent.

FAQ

Frequently asked questions

What is AgriTechTonic?+

AgriTechTonic is a UK infrastructure venture that co-locates a containerised edge data centre, a controlled-environment grow module, and a renewable energy hub. Waste heat from the data centre warms the grow module at zero marginal heating cost. The venture is operated by Gravitonic Ltd.

What is a modular data centre?+

A modular data centre is a prefabricated compute facility, often built inside a 20–40 ft ISO shipping container, that can be transported and commissioned far faster than a traditional brick-and-mortar hall. AgriTechTonic uses this format for edge and AI inference workloads, not hyperscale cloud campuses.

How does waste heat recovery work in a data centre?+

Servers convert a large share of electrical input into heat. Direct liquid cooling captures that heat in a fluid loop at 50–70°C instead of dumping it through air chillers. AgriTechTonic pipes the recoverable portion into an adjacent grow module so the heat becomes a useful input rather than waste.

What is controlled environment agriculture?+

Controlled environment agriculture (CEA) grows crops indoors with managed light, temperature, humidity, and nutrients. Typical methods include hydroponics, aeroponics, and mushroom cultivation. In the UK, keeping that environment warm is a dominant operating cost — which is why co-located data-centre heat matters.

What is direct liquid cooling?+

Direct liquid cooling (DLC) removes heat from servers by circulating coolant across cold plates or similar components, rather than relying only on air. Commercial systems from vendors including HPE and Danfoss produce exhaust heat in the 50–70°C range, which matches the temperatures needed to heat a CEA grow space.

What is PUE in a data centre?+

Power Usage Effectiveness (PUE) is total facility energy divided by IT equipment energy. A PUE of 1.0 would mean every watt goes to servers. Typical air-cooled halls sit well above 1.4. A well-run liquid-cooled modular hall can target roughly 1.2–1.3, which still leaves 20–30% of site energy as recoverable heat.

Can data centre heat be used to heat greenhouses?+

Yes. Waste-heat recovery from data centres is a documented engineering practice. AgriTechTonic’s differentiation is integration: the data centre, grow module, and energy hub are designed as one containerised stack so the heat loop is a default, not a retrofit.

How much water does hydroponic farming use compared to conventional?+

Peer-reviewed reviews report that hydroponic and other CEA systems can use around 90–95% less irrigation water per kilogram of crop than conventional field farming, especially in closed, recirculating loops. Actual savings depend on crop, climate, and whether the system recaptures condensate.

How many acres can a 40 ft container farm replace?+

Freight Farms specifies that its Greenery S, a 40 ft hydroponic container, has an equivalent land yield of 2–4 acres annually for leafy greens and similar crops. That figure is a yield-equivalence claim for those crop types, not a claim that every crop or climate matches it.
