Welcome
Organic Heat Exchangers (O-Hx) is the home of the patented “EnergiVault” technology, capable of storing and delivering vast amounts of thermal energy on demand to drive down the cost of cooling and provide infinitely scalable energy storage. Other thermal energy storage products have been limited by poor efficiency, limited charging and discharging flexibility and high costs. Ever increasing energy costs and a focus on net zero operations are key drivers for companies seeking more sustainable operations and reduced operating costs.

Reducing Greenhouse Gas Emissions

About O-Hx
O-Hx was formed in 2016 to house the development of more efficient cooling systems that can also act as utility scale energy storage solutions and apply for the relevant patents for these combined technologies. Whether, energy is stored as electricity, heat or cold, the principal of energy storage and balancing the grid, and prudent energy buying remains the same. Several eureka moments later, organic heat exchanger technology was invented and this was combined with AI (artificial intelligence) to provide an efficient cooling solution that also acted as a utility scale energy storage solution. These innovations were then housed in the Energivault solution. It is estimated that Energivault could reduce cooling led energy costs by up to 60% through load shifting, heat recovery, improved efficiency and demand response which also means significant reductions in carbon emissions based on carbon intensity of energy generation at the location. In addition, because Energivault acts as a demand side battery, it is estimated that costs can be reduced further (circa 20%) through allowing prudent buying of electricity when charging the system.
