Efficacy of North Korean Energy Storage Batteries: Innovation
In 2022, a solar farm outside Pyongyang integrated lead-acid batteries to store excess daytime energy. While the system''s efficacy lagged behind lithium-ion counterparts, it
Under North Korea's two-tier energy system, which prioritises industrial facilities, the only way for many citizens to access electricity is to pay state functionaries to allow them to install cables to siphon off power from local factories.
The Korea Energy Economics Institute in Seoul estimates that 2.88mn solar panels, mostly small units used to power electronic devices and LED lamps, are now in use across North Korea, accounting for an estimated 7 per cent of household power demand.
Jeong-hyeon, a North Korean escapee, told the Financial Times that many residents in Hamhung, the second-most populous city, “relied on a solar panel, a battery and a power generator to light their houses and power their television”. But solar power is still only a partial solution to the country's energy woes.
The KEEI estimates that more than 1mn panels were transported into North Korea from China in likely contravention of UN sanctions. Other, cheaper panels were probably assembled in North Korea with photovoltaic cells imported from China, said von Hippel.
