Rolls-Royce has signed contracts for five greenhouse projects in Belgium and Netherlands to be powered by the new B36:45 L6 and L9 gas engines. These engines set a new standard in power and efficiency with exceptionally low fuel consumption and emissions of NOx, CO2, SOx and particulates. It offers a 20% increase in power per cylinder compared to existing engines in the Rolls-Royce medium-speed range. The engines are produced at Bergen Engines AS, which is part of Rolls-Royce Power Systems.
The contracts comprise a total of seven engines which will provide heat and power to both new and existing greenhouses. Customers include MTS de Jong Francke in Holland, and VW Tuinderijen, Tuinbouwbedrijf Marc Pittoors, Tomato Masters and Tomw@tt in Belgium.
Rolls-Royce will be supplying and installing the complete CHP systems for the five greenhouses, consisting of generating sets, sound enclosures, exhaust gas systems including SCR and heat recovery systems, and control and protection systems.
The electrical power produced will primarily be used for greenhouse grow lights or exported to the regional grids. Heat extracted from the exhaust gas and the engine’s cooling water system will provide heating, and cleaned CO2 from the engines will be injected into the greenhouses to boost plant growth. In total, the technology achieves efficiency levels of more than 96%. All five projects will be handed over to customers in 2018 and will be covered by long-term service and maintenance agreements with Rolls-Royce.
