Greenhouse superconducting negative energy storage

Can energy-saving strategies be used in agricultural greenhouses?

In agricultural greenhouses, employment of energy-saving strategies along with alternative energy sources has been identified as a potential solution to address the intensive energy consumption of these cultivation facilities.

Does a greenhouse need thermal energy storage?

To provide climate stability inside a greenhouse (especially in terms of indoor temperature and humidity), Thermal Energy Storage (TES) systems are required. They both reduce the heat demand of the greenhouse and stabilize a desired indoor micro-climate for plants cultivated inside.

How much energy can a greenhouse system save?

The maximum COP was attained as 16. From TRANSYS simulation, it was found that the system can save thermal energy as 46.2 kWh/m 2 of the greenhouse area per year while maintaining the indoor temperature at 12 °C. Economic assessment approved the system’s profitability.

How can thermal energy storage improve climate stability in a greenhouse?

The exploitation of renewable energy sources such as solar, biomass, and geothermal heat can improve the sustainability of greenhouse cultivation and decrease its reliance on fossil fuels. To provide climate stability inside a greenhouse (especially in terms of indoor temperature and humidity), Thermal Energy Storage (TES) systems are required.

What are the new energy storage technologies?

The article mentions new energy storage technologies such as superconducting energy storage systems and high-temperature superconducting systems. These systems are used to effectively store power generation from renewable sources and in generators, transformers, and synchronous motors in power stations and heavy-industry facilities (Sci. Technol. 16 963).

How can net-zero energy greenhouses save energy?

Advances in Net-zero energy greenhouses and their heat storage are presented. Geothermal heat can save primary energy in greenhouses by more than 20%. Use of STES systems can improve the indoor air temperature by 3–5 °C. PCMs mitigate the energy consumption of net-zero energy greenhouses by 30–40%.
