Renewable Energy Sources in Protected Cultivation

Renewable Energy Sources in Protected Cultivation

The lab is focusing on the development of novel systems in greenhouses exploiting Renewable Energy Sources (RES). The interdisciplinary research is expanding from fundamental activities to real scale applications.

The use of RES aims at energy saving and zero consumption of fossil fuels and includes systems that use:

  • Solar Energy (passive solar collectors, hybrid solar energy saving systems, photovoltaics, nano-photovoltaics, green cooling)
  • Geothermal Energy (shallow geothermal systems, geothermal heat pumps)
  • Biomass energy (biogas from livestock waste or plant residues)

Protected cultivation deals with innovative crop systems that optimize production by rational use of water and fertilizers and enrichment of the air with CO2, such as:

  • Hydroponic crops on substrates
  • Hydroponic crops in floating system – floating hydroponics
  • Hydroponic crops on gutters

Furthermore, this research field includes environmental impact studies and in particular the environmental footprint of using RES in crops under cover. Indicators that are specified are:

  • Environmental Footprint (EF)
  • Carbon Footprint (CF)
  • Cumulative Energy Demand (CED)
  • Water Footprint (WF)
  • Water Use Efficiency (WUE)
