Key takeaways from South Korea’s Green Energy Expo
Green Energy Expo, South Korea’s largest solar event, attracted a higher number of visitors and exhibitors this year, underscoring the strength of the domestic PV industry, despite recent unfavorable regulatory changes.
The Hydrogen Stream: US team produces hydrogen from ocean water
A team of US researchers engineered a double-membrane system to minimize chloride oxidizing the anode. Meanwhile, the Spanish government supports Destinus to develop its hydrogen-powered supersonic plane and test it in 2024.
Hydrogenated amorphous silicon solar cell for BIPV, bifacial applications
Scientists in South Korea have developed a flexible, transparent solar cell with an average visible transmittance (AVT) of 88.3%. They have also created an n-type rear window layer to optimize bifacial operation.
South Korea to allocate $185 million for renewables rebates in 2023
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%.
Aqueous redox flow battery based on naphthalene diimide achieves high capacity retention
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 reveals plans for US heat pump factory
LG Electronics North America has revealed plans to manufacture 100% electric heat pumps in the United States for the first time.
The Hydrogen Stream: China Southern Power connects hydrogen plants to grid
China Southern Power Grid, a state-owned utility, has revealed plans to use alloy materials to store hydrogen.
South Korea cuts capacity allocations from 4 GW to 2 GW in solar tenders
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.
Paper-thin carbon fiber for battery with 428 Wh/kg energy density
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.
SDN unveils 595 W solar module with 21.28% efficiency
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.
