Providing a cost-effective and energy-efficient solution for greenhouses

European greenhouse businesses are increasingly looking for more sustainable and reliable energy solutions to reduce their carbon footprint and energy bills. The horticultural company Varegro has teamed up with COGEN Europe member Cummins to generate on-site electricity and heat for its 40,000 m² facility with a Combined Heat and Power (CHP) unit.

Dependable power source        
When power outages can have a costly and potentially catastrophic impact on production, reliability is key. The Cummins HSK78G CHP unit has been designed to operate effectively in extreme weather, ensuring minimal downtime, whatever the site conditions. With full power capability up to 40°C (104F) with standard turbo offering, and up to 55°C (131F) with high ambient turbo offering, the HSK78G is designed to adapt to the site’s environment, temperature, atmospheric and ground conditions.

Energy efficiency
As well as providing dependable heat and power to the energy-intensive facility, the HSK78G generator can recover CO2 via a Selective Catalytic Reduction (SCR) system, further increasing energy efficiency and reducing emissions. With electrical efficiency of 44.2%, the system achieves further fuel savings by turning waste heat into productive energy, which is used for heating purposes and CO2 recuperation from the exhaust. Surplus electricity is sold back to the grid, offering an additional return on investment for Varegro.

Stefan De Wit, Project Manager, Cummins Power Generation, said: "For Varegro, being able to rely on a power source that can withstand any environmental influence is critical. The addition of exhaust gas heat exchangers and heat condensers provides total efficiency of 103%. - offering maximum efficiency with the greatest possible cost savings to the customer.”

The HSK78G is the largest of Cummins’ gas generator range, which includes the C25G and QSK60G series, offering a range of integrated solutions from 500kW to 2MW. Cummins’ gas generators combine fuel flexibility with reliability, providing significant cost of ownership and energy efficiencies for any gas power need.
