Greenhouse cogeneration: bringing added value

Greenhouse cogeneration provides considerable energy efficiency in greenhouse applications, as part of the production chain and is a highly flexible source of electrical energy. The technological characteristics of greenhouse cogeneration actively contribute to the growth of crops, through the combined production of heat, light and carbon dioxide (CO2). The electrical energy produced with greenhouse cogeneration can be used for lighting or put on the national grid, if economic benefits can be had, while the heat can be used to produce hot water to heat the greenhouses or for specific uses. Lastly, the CO2 in the exhaust gases can be collected and used to stimulate plant growth, increasing production yields by up to 30% compared to traditional crop growing in greenhouses without carbon dioxide enrichment. This means the growing period can be extended, increasing crop quantities.

“Self-produced electricity rather than using the increasingly expensive ways to heat greenhouses and CO2 to fertilize crop: these, in summary, the potential benefits of cogeneration”.
