GEOTHERMAL ENERGY UTILISATION IN THE GREENHOUSE VEGETABLE SECTOR IN HUNGARY

Producers in the vegetable sector are increasingly shifting from fossil fuels to renewable energy, and the use of geothermal energy in Hungarian greenhouses has a real future.
Although the investment costs for developing a geothermal heating system are relatively high, significantly lower operation costs can be achieved with this type of system than with fossil fuel energy sources.
As of 2014, thermal water reinjection is not required in Hungary, which lowers the investment cost of thermal wells, possibly making it more likely for vegetable producers to adopt this technology.
Thermal water can be used as a heat source to keep the temperature of a greenhouse at the level required for vegetable production.
There are many operating thermal wells in Hungary.
Most of these are located in the south of the country, in the same region that has the highest concentration of vegetable production.
The present work was designed to present the opportunities of thermal water utilisation in Hungarian greenhouses.
