The Korea Institute of Energy Research has developed a solid oxide electrolysis cell stack that uses a special kind of separator plate to ensure proper flow of hydrogen and oxigen after water splitting. Samsung Electro-Mechanics and Bumhan Industries are now cooperating with the research center to improve relevant manufacturing process.
OCI has revealed plans to invest $617.9 million to expand production at its Malaysian manufacturing facility from 35,000 to 56,600 metric tons.
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have identified a high-energy, high-power hybrid sodium-ion battery capable of charging in just a few seconds. The system integrates anode materials typically used in batteries with cathodes suitable for supercapacitors.
The South Korean government has announced a new package of measures to support agrivoltaic projects. It says that the agrivoltaics business should be a priority for agricultural companies.
Two Korean research institutes are designing the 2.2 km × 2.7 km Korean Space Solar Power Satellite project with the aim of providing approximately 1 TWh of electricity to the Earth per year. The proposed system should use 4,000 sub-solar arrays of 10 m × 270 m, made out of thin film roll-out, with a system power efficiency of 13.5%.
The Japanese manufacturer claims the new product has a seasonal energy efficiency ratio of up to 9.47 and a seasonal coefficient of performance of up to 5.20.
Researchers utilized crown ether B18C6 and interfacial passivation at the perovskite-hole transport material interface to address lead leakage, improve power conversion efficiency and the cell’s ability to withstand humidity.
Conceived by South Korean scientists, the cell was built with an electron transport layer made of tin oxide via a low-temperature process. The device reportedly achieved the highest power conversion efficiency ever reported for flexible quantum dot solar cells.
The system uses difluoromethane (R32) as the refrigerant and has reportedly a seasonal coefficient of performance of up to 4.69.
Researchers in South Korea have analyzed the feasibility of using thermoelectric generators in combination with residential solar-assisted ground-source heat pumps and have found that the thermoelectric devices may act as a suitable power source for data loggers and other sensors in a building system.
