Shining a light on Tomatoes

Royal Pride Holland is using the J624 GS engines to power the greenhouse's new cogeneration plant. Some of the power generated is used for lighting for the tomatoes, but most is supplied to the public power grid. Because the waste heat from the engines can be used at very low temperatures, and the CO2 in its exhaust gas can also be used, the overall level of efficiency is 95 percent.

CHP: 3 primary criteria for successfull cogeneration projects in power plants

On world average only 9% of electricity production comes from cogeneration or CHP. However, some countries are well above. For instance, Denmark has more than 60%.

Cogeneration can not only deliver economic benefits but also environmental ones (avoiding CO2 emissions). If that is the case, why are not more countries reaching the level of Denmark?

This paper describes the three main criteria…
