The Heat Vault
The Heat Vault is an underground energy store within naturally occurring rocks in the form of heat.
It can be constructed almost anywhere.
The store comprises an architecture of multiple deep boreholes, some to input heat, others to extract it.
The energy input can be from various waste heat sources or can be waste or excess electricity from the power grid or from dedicated renewable power sources.
Heat Vault collects energy in off-peak hours or in seasons with low energy demand at low cost. Energy storage can be for days, weeks, months or even decades, something unattainable by any other known method.
It supplies energy at peak times or peak seasons which have high energy demand.
Because it is completely decoupled from global hydrocarbon volatility, supply can be at reasonable cost to consumers to suit need.
Heat is one direct output. But coupled with other assets above ground, Heat Vault can also supply cooling, electricity or green hydrogen.
And because it is modular, it can be built to match requirements, including the large infrastructure markets at gigawatt-hour or terawatt-hour scale, something unachievable by other types of storage at favourable cost.
Imagine securing the annual supply of energy for all of Manhattan as heat, deep beneath one third of Central Park.
It could be built at this scale.
New application of oil and gas, environmental remediation and industrial technology developments.
Based on research at Gothenburg, Chalmers and Yale universities.
What Heat Vault does
Solves Renewables Intermittency
Improves Solar Efficiency
Recycles and augments Industrial Heat
Decarbonises Heat Networks
Enhances Geothermal Energy use
Accelerates Renewables adoption
Repurposes power utility assets
Removes Nuclear Heat excess
STORES AND SECURES VAST ENERGY FOR DECADES
THE HEAT VAULT IS LIKE AN UNDERGROUND BANK INTO WHICH DEPOSITS OF GREEN ENERGY ARE DEEP STORED WHEN MOST AVAILABLE AT LEAST COST AND FROM WHICH THEY CAN BE WITHDRAWN WHENEVER NEEDED
Rocks are good at storing hot or cold energy
Heat Vault can take the path to hot or cold, or do both together
