07. Development of Environment-friendly Energy-saving Technologies and Alternative Bioenergy
  • Zero Fossil Energy in Greenhouse Crops Production System
  • At present, heating costs for crop production in a proper temperature-controlled environment represents the biggest portion of greenhouse production costs - more than 40%, and continues to increase every year. Therefore, there is an urgent need to develop technologies to overcome this situation. Crude oil price is unpredictable and unstable, which frequently causes an unbalanced energy supply and demand in this country. Consequently, the demand for alternative energy sources becomes greater than ever in the greenhouse crop production system. Agenda 12 includes the development of superior heat-keeping methods for the facilities, heat efficiency promotion techniques for cooling and heating equipment, and utilization technologies for biofuels, renewable energies, solar, and geothermal to lower the excessive heating costs.
  • Korean crops have to be more competitive in the international markets. Therefore, this agenda aims at decreasing the portion of heating costs in greenhouse production by at least 20%, which is the level in European countries and Japan. In addition, major research areas focus on the development of integrated technologies consisting of LED irradiation techniques and their effects in terms of yield increase and functionality for crops; energy crop breeding for maximum production of bio-diesel and bio-ethanol in all available lands such as reclaimed and idle land. Other research areas include developing utilization technology for extra solar energy for greenhouses and natural energy such as water, underground air, and fuel cell electricity production from micro-algae and agricultural byproducts of woody trees and animal wastes.
  • Setting this agenda for success will lead to the RDA playing a major role in the industrialization of energy-saving technologies and the maintenance of close partnerships with university research groups, related institutes, farmers, and industries. In addition, the RDA will construct a network of governance with regional rural development centers for early dissemination of technologies developed through this agenda.
