Overview of the Research Project

Provide sustainable heat energy with a ground-source heat pump designed for arid regions
Tajikistan has few hydrocarbon resources and is dependent on hydroelectric power for 96% of its energy, one of the highest rates in the world. However, it still faces issues with energy access. In the cold season, demand for heating increases, straining the electricity supply, and restrictions are imposed in rural areas. Since the Soviet period the country has used coal as an alternative, but these facilities have become dilapidated and their use, however tempting, is not ideal from the viewpoints of both air pollution and global warming. We are therefore developing an energy-saving, clean ground-source heat pump designed for use in arid regions.

Improving energy access and tackling global warming through the use of ground heat sources
Ground heat has not been utilized because of the low water table and poor soil water content. The development of a ground-source heat pump designed for use in arid areas (Tajikistan model), will contribute to combating global warming and tackling energy access not just in Tajikistan but also in Afghanistan and other neighboring countries.
