Financial Payback

Financial - Thermal Energy

EnergiVault delivers a market-leading Return on Investment by integrating system efficiency, load-shifting, and the use of on-site renewables. Payback periods of less than five years are easily achievable.

Load Shifting

Thermal Energy Storage

EnergiVault is unique as it operates as a slow-charge, rapid-discharge system. This allows it to utilise inexpensive overnight electricity to displace costly peak electricity, or even electricity generated on-site.

Operational Resilience


EnergiVault enhances operational resilience by providing uninterrupted cooling supply and peak demand support. This enhances the reliability and efficiency of industrial cooling systems and prevents costly operational shutdowns..

Effective communication, seamless integration
