Meet Omnigreen

A revolutionary modular & scalable renewable energy solution for the industrial & commercial sectors

Reduce Your Energy Bills & Emissions up to Full Decarbonization

Help your organization achieve greater energy savings, reduce environmental footprint and emit less polluting gases.

Omnigreen is a revolutionary modular and scalable renewable energy solution combining multiple energy sources to generate industrial steam, hot water or hot air on demand.

Omnigreen - a True Game Changer for Diverse Sectors and Industries

Sustainability and the incorporation of renewable energy solutions are among the great challenges energy facilities are facing nowadays. Many of which were built several decades ago. In light of this, it is essential that infrastructure and energy managers must adapt these facilities to achieve greater energy savings, reduce environmental footprint and emit less polluting gases. Omnigreen helps achieve these environmental goals.

Storage Based Steam Generator

  • Source: Renewable energy (PV, wind, etc) or direct grid
  • High temperature storage: embedded electrical heaters
  • No gasses or emissions
  • Modular design
  • Input and output conditions stay the same
  • Enables to use intermittent electrical sources for a supply of steady steam or hot water


Flue Gases to Hot Water

By using the residual heat and decoupling the thermal energy consumption from the electrical consumption – the unit will highly increase the cycle efficiency.
Residual heat can be used to charge the unit at intervals or continuously
for 24 hours.
Charging and discharging can take place in parallel or in sequences with no dependency between the charging cycles and discharging cycle.


Biomass to Steam

  • Hot gasses up to 750 ºC
  • Industrial steam (180°C, 10 bars) or hot air to the process
  • Decouples between the continuous charging time of the Biomass source and the different delivery time slots of the output


Utility Scale Storage Solution

  • Produces superheated steam, using its inherent steam generator
  • The system controls the pressure and temperature, assuring a steady output flow, regardless of the unit charging level


  • Supplied and shipped as one unit
  • Short installation: Connection of interfaces:
    ・ SW/Control Interface
    ・ Piping Interface
    ・ Ground Preperations
    ・ Water Requirements
    ・ Installation Tools
    ・ Acceptance Test
  • Full acceptance test installation completed
