Utilizing Geothermal Energy for Sustainable Farming

What is it about?

The project explores the utilization of geothermal energy for agricultural purposes in Saudi Arabia, specifically for soil warming during wintertime and greenhouse cooling at King Faisal University's farm. The availability of geothermal resources in the Al Ahsa region hasn't yet been explored, but it is assumed that there is potential, similar to the availability in Al Lith region. The study focuses on maintaining a suitable soil temperature for vegetation and reduces water consumption for greenhouse cooling by using geothermal earth pipes instead of evaporative cooling systems. The project utilizes American Society of Agricultural and Biological Engineers (ASABE) standards and engineering standards from DuPont to ensure a safe and reliable design.

Why is it important?

The utilization of geothermal energy for agricultural purposes is important because it helps extend the growing season, maintains suitable soil temperatures for plant growth, and reduces the dependence on limited water resources in regions with absolute water scarcity. This research contributes to sustainable agricultural practices and food production, particularly in areas with geothermal energy availability. Key Takeaways: 1. Geothermal energy can be used for soil warming during wintertime, maintaining suitable soil temperatures for plant growth. 2. The project proposes a basic design for soil warming using geothermal energy in the Al Ahsa region of Saudi Arabia. 3. The research also considers greenhouse cooling at KFU's farm using a geothermal earth pipe, which provides cooling without consuming water. 4. The concept can be applied globally where geothermal energy is available and soil warming or greenhouse cooling is required. 5. The usage of geothermal energy and water-saving techniques contribute to sustainable agriculture and food production.
