Greenhouse facilities

INNIO JENBACHER equipment helps to grow vegetables, lettuces, berries and other plants efficiently in greenhouse complexes.

The benefits of using cogeneration in greenhouse complexes go far beyond simple heating and lighting. When a combined heat and power (CHP) system is used in a greenhouse complex, the gas engines from INNIO Jenbacher not only provide electricity and heat, but also carbon dioxide (CO2) for plant fertilisation.

During crop growth, the plants convert the CO2 in the air into carbon through photosynthesis. Greenhouse plants absorb more CO2 because of the increased artificial light. By enriching the greenhouse with CO2, growth and yields can be significantly increased.

How does it work

The standardised greenhouse CHP technology is based on INNIO Jenbacher gas engines, supplemented by a catalyst, heat exchanger and other auxiliary equipment. The whole set of equipment is a single complete solution. The energy produced by gas engine cogeneration systems includes electricity, heat, and CO2 from the engine’s exhaust gases. When the natural gas is combusted in the engine, almost 1.8 kilograms of CO2 are produced per cubic metre of natural gas. After cleaning the exhaust gases with special catalytic converters (selective catalytic reduction (SCR) and oxidation), they are cooled via a heat exchanger to a temperature of around 50 °C and are fed into a greenhouse for CO2 enrichment.

INNIO Jenbacher aims to ensure maximum plant safety. A special measuring and protection device, therefore, ensures that the exhaust gas levels are constantly monitored.

Benefits and special features

  • All year-round efficiency. The heat storage allows the supply of CO2 and heat regardless of the time of year.

  • Cheap electricity and heat generation. The cost of energy from the in-house mini-CHP is 40 to 60 % lower than the grid tariffs, allowing the plant to pay for itself in 2 to 4 years, depending on the parameters and operating conditions.

  • High efficiency. The overall fuel efficiency of the units is up to 90%. Generate electricity with an efficiency of 47% and together with heat up to 90%. Reach full power capacity in 2 minutes.

  • Energy independence and energy efficiency. Independence from the regional power grid, and therefore from tariff increases. No construction costs for supply and distribution networks. CHP plants are built close to the facilities. Low investment costs, ability to regulate capacity. Possibility to feed electricity into the public grid.

  • Reliability and security. The DIA.NE* XT engine management system offers a high degree of operating safety and availability, as well as reliability, thanks to its integrated plant lighting controls.

  • Environment. The LEANOX* lean-blend and low dry gas emission (DLE) combustion ensure extremely low emissions.

  • Additional income. Combined heat and power generation systems using Jenbacher gas engines offer the potential to generate additional revenue while redirecting surplus electricity generation into the public grid.
