The Heat Vault Company
Some of our biggest ventures need to be more chill.
AEVOLITH™ (ay-vo-lith) means eternal stone. It is the Product range brand name for The Heat Vault Company.
COLD VAULT
The global cooling demand has hit a physical wall. From industrial heat to fragile food chains, legacy systems are breaking. Introducing the Cold Vault: a geotechnical battery that transforms natural solid rocks underground into a massive super cold thermal reservoir.
Using proprietary technology, we store cold energy down to -100 Celsius. The novelty lies in the physics of phase change: freezing water-saturated geology into artificial permafrost to achieve five times the energy density of conventional chilled water. Cold Vault is a subterranean freezer capable of months to years of storage.
This is a generational leap for all high-heat sectors. By decoupling cooling from real-time power, the Cold Vault provides zero-water thermal management for power plants, food cold chains, and industrial manufacturing. It enables rapid flash-freezing and CO2 liquefaction, transforming cooling from a parasitic liability into a strategic, renewable-ready asset. This is the cornerstone of resilient infrastructure.

THE AI COOLING CRISIS
The explosive growth of AI has hit a "physical wall". Legacy air-cooling is thermodynamically obsolete for modern AI racks, which consume up to 100+ kW—a 25-fold density increase over traditional setups. This creates a "trilemma" of skyrocketing power demand, fragile energy grids, and massive water consumption (up to 1.8 billion liters annually per 100MW facility).
The Cold Vault is a game-changing "geotechnical battery" that transforms the earth beneath data centers into a massive thermal reservoir. Its novelty lies in utilizing latent heat via phase change, actively freezing water-saturated ground into artificial permafrost. This achieves five times the energy density of conventional chilled water storage.
-
Decoupled Demand: Provides up to 52 days of cooling autonomy, transforming data centers from grid liabilities into flexible assets.
-
Resource Independence: Achieves zero operational water consumption.
-
Economic Superiority: Reduces peak grid connection requirements by 26% and can slash the 10-year cooling TCO by approximately 96% through renewable energy arbitrage.
By leveraging the "secret sauce" of physics, the Cold Vault secures digital infrastructure for the next fifty years.
FROZEN RESILIENCE
The Cold Vault represents a strategic shift from "just-in-time" vulnerability to "just-in-case" food security. While tactical measures like backup generators fail within days due to fuel dependency, the Cold Vault leverages the Earth's geology to create a national-scale strategic buffer.
By freezing water-saturated ground into massive blocks of artificial permafrost, the system transforms the subsurface into a giant thermal battery. This immense thermal mass is capable of maintaining sub-zero temperatures for weeks, months, or even years with minimal energy input.
This architecture effectively decouples food preservation from the moment-to-moment stability of the power grid. It provides a passive, geologically integrated reservoir that can safeguard regional food supplies against prolonged blackouts or renewable energy intermittency.
Ultimately, it offers a permanent, enduring solution to prevent catastrophic food spoilage and ensure stability for millions in an increasingly uncertain energy landscape.
THE BIG PICTURE
There is a rising importance of industrial cooling across the European Union, highlighting its transition from a secondary utility to a critical pillar of operational safety and economic stability. Distinction can be made between direct process cooling used in manufacturing and the essential thermal management required for nuclear safety, automated robotics, and high-density AI data centres.
Italy, France, and Spain are the leading markets for cooling demand, driven by their respective strengths in food production, power generation, and pharmaceuticals. As digitalisation and automation accelerate, there is forecast a significant surge in energy requirements through 2035, particularly within GPU-dense computing environments. Ultimately, managing massive thermal rejection is now as vital for European industrial competitiveness as the generation of electricity itself.
Cold Vault represents a paradigm shift in how to achieve the vast scales of cooling required across the EU.
