Abstract

This paper reports the effectiveness of the introduction of NGDG-SOFC (Natural Gas-Fueled Distributed Generation Solid Oxide Fuel Cell) as a solution to social problems that could arise in the unification era due to the power shortage in North Korea. Under the actual operating conditions of the plant, a stack that operates at a voltage of 33.87 V and current of 31.24 A was modeled with a gross output of 1.06 kW and a net output of 1.00 kW considering the balance of plant (BOP) consumption power. Considering the average primary energy consumption in the ASEAN countries in 2020, 2,870 MW was estimated as the amount of power generation required in North Korea. Also, the gross area of the plant and the annual fuel cost were estimated. Consequently, it is concluded that the area of 861 km2 which corresponds to 0.71 percent of the gross area of North Korea, and fuel cost of about 1,474 million $/year are required. The introduction of NGDG-SOFC plants is believed to follow the global trend of renewable energy and resolving the power shortage in North Korea in an eco-friendly manner.
