Thermal Energy Storage Applications in Closed Greenhouses (Annex 22)

Increasing attention is being paid to thermal energy storage (TES) in greenhouse systems as a means of enhancing crop production while reducing primary energy (fossil fuel) use and operational impacts to soil, water and air. TES leads to the “closed or nearly closed” greenhouse concept, which subsequently allows for active environmental control, avoiding the need to control of environmental variables by opening and closing windows – an act which also unintentionally releases CO2.

Thermal energy storage has an important contribution to make to the viability and sustainability of horticultural greenhouse systems because it allows for a renew-able, continuous, and adaptable supply of heating, cooling, and dehumidification. The nature of this contribution is cardinal in light of concerns of increasing fossil fuel expenses and climate change. The industries which provide us with food and plants (i.e. potted plants, flowers, sod, trees) strive to maximize the outputs of their greenhouse system while simul-taneously minimizing their inputs. They do this to meet ever-increasing demands for competitive pricing as well as product quality and security assurances. There are three key ways in which the integration of TES simultaneously addresses the system’s outputs and inputs:
  • Energy savings
  • Controlled CO2 and humidity
  • Fewer chemicals
