Hanwha Solutions to Reduce 1,500 Tons of CO2 Annually Using Waste Heat

[Asia Economy Reporter Choi Dae-yeol] Hanwha Solutions announced on the 25th that it will start a business to produce hot water using heat generated from its production process and supply it where needed.

As a project to reduce carbon dioxide, Hanwha Solutions plans to produce hot water using waste heat generated at its Ulsan Plant 3 and supply it to the nearby Lotte Chemical Yongyeon Plant 2. The company expects that the two plants will be able to reduce 1,500 tons of carbon dioxide annually, equivalent to the amount produced by 430 passenger cars.

This project is based on a national project supported by the Ministry of Trade, Industry and Energy and funded by the Korea Institute for Advancement of Technology. BK ENG, which received R&D investment support, installed a heat exchanger at the Hanwha plant, and Hanwha supplies process waste heat to the heat exchanger to produce hot water, which is then delivered to Lotte. Lotte uses the received hot water as an energy source to operate absorption chillers, saving electrical energy. The cooled water is reheated with waste heat and reused, establishing an energy circular economy system.

Lee Dong-joo, head of Hanwha Solutions Ulsan Plant, said, "We will continue to strengthen ESG (Environmental, Social, and Governance) management for environmental coexistence by cooperating with companies within the industrial complex."
