A variety of vaccines of Covid 19 have been developed by different drug makers. Each vaccine brand requires different storage temperature ranged from 2-8°C, which then requires a cold storage box. In Indonesia, vaccine transportation and storage become big challenges to ensure the vaccines in good condition before use. This research focused to find out the possibility of using geothermal energy from Lahendong geothermal power plant unit 5 in Tompaso, North Sulawesi, for 5 liters-cold storage for Covid-19 vaccine using ammonia-water absorptive refrigeration and to identify the possible temperatures for storage of vaccine. Based on the absorption refrigeration system calculation, the current study found that the average evaporator temperature is 3°C, with cooling load of 1.03 kW and COP of 0.43. This cooling load requires a brine of 59.98 kg/s from the Lahendong geothermal power plant.
