LG Chem plans to produce hydrogen as a key component of its long-term 2050 Net Zero corporate sustainability goal. Aligned with this goal, South Korea’s largest chemical company said it would establish a plant in Daesan in Korea with the capacity to produce 50,000 tonnes of hydrogen annually by the second quarter in 2024. The new plant employs technology which converts methane to hydrogen by creating a chemical reaction under high-temperature steam. Hydrogen will be made from methane off-gases generated by the naphtha cracking center in the process of producing feed-stocks. This hydrogen will then be depolymerized under high-temperature to be used as fuel again.Construction of LG Chem’s hydrogen plant is expected to commence in the first half of 2023 and scheduled for completion by the second quarter of 2024. Once fully operational, LG Chem expects the plant to reduce carbon emissions by 140,000 tonnes annually by replacing methane used in the NCC process with high-purity hydrogen, which does not create carbon dioxide during combustion.The petrochemical industry produces base chemicals such as ethylene, propylene and buta-diene which are made by breaking down naphtha at high temperatures. Methane is commonly used as a heat source for the NCC process which generates a large amount of carbon emis-sions.
