The South Korean government says its rebates for building-integrated PV (BIPV) systems have gone up from 13.4% to 15%, but its rebates for conventional rooftop PV systems have gone down from 50% to 47%.

Scientists in South Korea have developed a highly soluble, stable organic redox-active molecule for use in aqueous redox flow batteries. The newly developed naphthalene diimide (NDI) molecule offered higher storage capacity than existing vanadium devices.

LG Electronics North America has revealed plans to manufacture 100% electric heat pumps in the United States for the first time.

China Southern Power Grid, a state-owned utility, has revealed plans to use alloy materials to store hydrogen.

South Korea has cut its 2030 renewable energy target from 30.2% to just 21.6%, as it seeks to reduce support for solar and other clean energy sources, while preparing the ground for more nuclear power and liquefied natural gas. A lobby group is now challenging the plan in the Seoul Administrative Court.

South Korean scientists have developed a new way to integrate a lithium-metal anode into a battery and reach higher energy capacity levels than current lithium-ion tech. They worked with a carbon fiber paper infused with lithium and demonstrated an energy density of 428 Wh/kg, along with encouraging performance in stability and potential ease of manufacturing.

South Korea’s SDN has developed new bifacial solar modules based on M10 wafers. It claims the new panels are the largest to be produced in South Korea.

The consortium says it intends to develop a simplified approach and best practices to produce 2T perovskite-silicon tandem solar products. The modules should have a bifacial design, glass-glass encapsulation, and a power output of over 300 W/m2.

South Korean researchers have developed a heat trading system including a ground-source heat pump, solar thermal collectors, a fuel-cell system, and two heat storage tanks for district heating at hours of peak solar production.

Scientists in South Korea have developed a forecasting model to better manage electric grids with high penetration of intermittent renewables. The model was tested using historic data from Pennsylvania-New Jersey-Maryland (PJM) grid in the United States, and shown to accurately forecast the availability of renewable energy resources up to one day in advance.
