[Asia Economy Reporter Han Yeju] LG Innotek announced on the 23rd that its independently developed innovative material core technology recently obtained the Ministry of Trade, Industry and Energy's 'Green Technology Certification.'

The Green Technology Certification is a government-recognized system for eco-friendly technologies that contribute to sustainable growth. The technology certified this time is LG Innotek's 'Nano Polycrystalline Thermoelectric Material,' a core material applied to thermoelectric systems for industrial power generation such as ships.

Thermoelectric power generation is a method that converts thermal energy into electrical energy. It utilizes the property of electrons moving from a high-temperature area to a low-temperature area, producing electricity by creating a temperature difference on both sides of the thermoelectric semiconductor material. Since thermoelectric power generation recovers waste heat to regenerate electricity, it can reduce the fuel used to operate power generators. When a thermoelectric system equipped with nano polycrystalline thermoelectric material is installed on a ship, it is estimated to save 892 tons of fuel annually per vessel.

It also has an effect of reducing greenhouse gas emissions by 2,903 tons annually. Considering that a 20-year-old pine tree absorbs 3.9 kg of carbon dioxide per year, the thermoelectric system for ships has an effect equivalent to planting about 740,000 pine trees. This is why the nano polycrystalline thermoelectric material developed by LG Innotek is recognized as an eco-friendly technology.

In addition to ships, if thermoelectric systems are applied to processes such as steel mills, it is expected to reduce carbon dioxide emissions by about 40 tons annually based on a power generation capacity of 10 kW.

LG Innotek plans to proactively respond to the global climate change crisis and take the lead in resource circulation and greenhouse gas reduction activities by actively introducing and expanding eco-friendly technologies throughout the entire process of product development and production. It also plans to continuously manage the environmental impact of major products, including carbon emissions, through obtaining 'Environmental Product Declaration Certification.'

President Jung Cheol-dong said, "The importance of environmentally friendly products and technologies across all industries will continue to grow," adding, "As an ESG leading company, LG Innotek will continue to expand the development of various eco-friendly technologies and products to innovate customer experiences."
