Partnership with Energy Innovation Agency

We are delighted to announce a strategic partnership between O-Hx and the Energy Innovation Agency, uniting our shared vision for a sustainable and energy-efficient future.

This partnership unites O-Hx’s innovative EnergiVault cold thermal battery technology with the Energy Innovation Agency and it’s wide range of low-carbon solutions.

Our goal is to combine O-Hx’s cold thermal energy storage and management know-how with the Energy Innovation Agency’s dedication to green, cleantech companies. Together, we aim to improve market access for innovative energy solutions, fast-tracking progress towards net-zero objectives.

For more information, please visit the Energy Innovation Agency’s website.


EnergiVault is a cold thermal energy storage system, designed to bolster industrial refrigeration. It captures cold energy as ice slurry, with minute ice crystals in fluid, offering flexible discharge for both process and space cooling alongside current refrigeration systems.

EnergiVault boasts two key advantages. First, it separates the cooling demand from electricity supply, allowing charging with low-cost/low-carbon electricity and discharging to offset high-cost/high-carbon power. Second, it delivers peak cooling support, stepping in when existing systems can’t meet the cooling demand.
