The energy used in the agriculture sector is mainly thermal energy. Accordingly, clean energy that can produce thermal energy is solar heat, biomass, and terrestrial heat, and in recent years, energy using temperature difference is attracting attention as a new renewable energy. This study of terrestrial heat and bioenergy with high applicability to the agriculture sector reviewed technical applicability by energy source and economic efficiency and showed policy implication in the supply of energy sources and distribution expansion.
Among new renewable energy, the currently supplied energy for the purpose of heating in the field of agriculture is the heat pump system and wood-pellet stove using terrestrial heat. In case of use of new renewable energy for heating, direct effects include reduction of fuel expenses and increase in productivity, and indirect effects include reduction of CO2 emissions. Nevertheless, the reason the supply of new renewable energy is insufficient seems based on several problems described below.
In the case of a terrestrial heat pump, because a farmer must take responsibility by paying 210 million won for installation in a 1 ha greenhouse, this is not an easy investment. Besides, it is attributed to an insufficient understanding by farmers of terrestrial heat pump systems, site acquisition problems for facility installation, low technical level of design, and construction companies. In the case of wood pellets, inconvenience of pellet purchase, problem of storage security, and purchase price problems are pointed out.
For the purpose of wide utilization of clean energy sources such as terrestrial heat energy and woody biomass in the agriculture sector, the basis expansion of these sources should be implemented. In particular, support for facility installation of the new renewable energy should be planned, and consistent technology development and collaboration with professional construction companies to reduce the supply prices of clean energy facilities applicable to the agriculture sector are required. Most clean energy is based on a region; accordingly, system development that produces and consumes clean energy in a regional unit is more important than anything else. For this system development, it is required to launch benchmarking for foreign advanced cases and related systems.
