Challenges
In order to heat greenhouses to grow various sorts of tomatoes, an even temperature and humidity must be maintained in throughout the year. Geothermal energy is the primary source of supplying greenhouses with heat. A natural gas-fired boiler is built-in as a high temperature heat source.
Besides heat energy, greenhouses also consume plenty of electric energy, primarily for lighting.
The growth of tomatoes is accelerated when a supply of CO2 is added to the other nutrients.
Solution
We supplied and installed two cogeneration units of 2 x 550 kW nominal power. The units provide heat and electric energy and are designed to cover a base load supply of heat throughout the year (8,700 hours) and variable consumption (4,000 hours) of both heat and electric energy during the heating season.
A CO2 separator is mounted on the flue gas evacuation ducts of a 2G Avus 500 plus CHP unit. It serves to capture CO2, which is then delivered to the greenhouse. This technologically advanced solution improves the produce growth conditions and also drastically reduces CO2 emissions, thus having additionally positive environmental impact.
With the preparation of investment documentation, Eko Star successfully applied to enter the scheme to obtain feed-in tarrif and, as 2G Energy’s authorized partner, took over long-term maintenance of the installed plants.
