Gyre Energy raises $1.3m to make the world’s cold stores work less when power costs most

Across a scorching European summer, the least glamorous machines in the economy have been quietly straining. In cold stores and distribution depots, compressors run harder as the mercury climbs, pulling more power at exactly the hours power is dearest. It is a problem most operators have simply lived with.

Gyre Energy, an Oxford-founded energy tech company, has built a business on the wager that they no longer have to, and it has just raised more than $1.3m to prove the point at a far bigger scale.

The pre-seed round, a mix of investment and grant funding, was led by Speedinvest with participation from rule30 and Plug and Play. The money underwrites Gyre’s largest deployment to date, and its first with a global logistics leader, one of the world’s biggest movers and keepers of temperature-sensitive goods.

The customer cannot be named yet, citing commercial confidentiality, but the company will install its platform inside a chamber of a 140,000 square foot cold chain operation, with results measured against an IPMVP baseline.

The idea underneath is deceptively simple. Gyre’s software studies how a site behaves, forecasts when it will need cooling, and trims energy use without letting the temperature drift. Its thermal energy storage then does the clever part, banking cooling capacity when electricity is cheap and cleaner, and releasing it when prices spike, so the hardware runs least when running it costs most.

“We are an applied AI company, having taken advanced AI out of the lab and applied it to hard, physical, real-world problems. We help companies turn operational systems into intelligent infrastructure, making something invisible smarter, cleaner and more resilient. Our core IP is our models and thermal energy storage.

We use physics-based AI to understand the thermal dynamics of each cooling site, down to how individual rooms and assets behave, and then optimise how the whole system runs. The thermal storage is an enabler, but the intelligence is what unlocks the savings,” said Dougald Coulson, Gyre’s co-founder and chief executive.

The timing is not incidental. Heatwaves across Europe and beyond are leaning hard on cold chains, buildings and power grids at once. The International Energy Agency reckons cooling already accounts for roughly a tenth of global electricity, and nearly a fifth of the power used in the world’s buildings, and it has warned that the load is straining grids around the world.

Global electricity demand is now forecast to grow about 50% faster between 2026 and 2030 than it did over the previous decade, driven by cooling, data centres and electrification, precisely the demands Gyre says its platform is built to tame.

The company is not starting from a standing position. In its first published commercial deployment, at a 2,900 square foot frozen store run by a UK chilled and frozen distributor, Gyre cut electricity costs by 38% and daily energy use by 35%, with a payback period of under 18 months, and all without ripping out and replacing the existing kit.

“Energy prices are the most direct challenge. For many of our customers, cooling is one of their largest operating costs. In cold storage, cooling can account for the majority of site energy demand, so any movement in power prices has a direct impact on margins. Grid constraints are another factor.

As electrification grows and cooling demand rises, many sites will face higher costs or limits on what they can draw from the grid. Climate is also part of the picture. Hotter conditions increase cooling loads and make temperature control harder,” said Dougald Coulson, Gyre’s co-founder and chief executive.

That reframing is what drew the backers. “Cooling is one of the most fundamental and overlooked problems in the energy transition, and Gyre is tackling it head on,” said Alex Davis, an investor at Speedinvest. “This is AI applied to the real world, delivering lower energy consumption and more resilient supply chains.”

Coulson founded the company in 2024 with Michael McKenna and Tom Gibson, all three Oxford MBAs with backgrounds in machine learning and energy systems. Since then Gyre has been named a MIT Climate Solver, picked up multiple Innovate UK grants, and taken second place in the SXSW London Venture Spotlight.

Its next horizon is the one everyone is watching: the data centre, where a scramble is under way to keep AI’s servers cool and the lights on. As the grids that feed them buckle, from Denmark to the wider continent, the humble refrigerator may turn out to be one of the more useful tools on the network.
