SEOUL -- POSCO Energy, an energy producer affiliated with South Korea's POSCO steel group, teamed up with Innowill, a domestic compact heat exchanger developer, to demonstrate and develop advanced cogeneration technologies. The company aims to secure core technologies that can reduce carbon emissions using waste heat generation and lay the groundwork for entering the waste heat generation market.

Cogeneration refers to the use of waste heat that occurred during the manufacturing process to generate electricity and useful heat. The conventional method was complicated because it made steam using organic materials with boiling points lower than that of water, making it difficult to maintain and expensive to invest in.

The waste heat generation method to be demonstrated by POSCO and Innowill will use air turbine technology that directly heats air and turns turbines. Air turbine technology does not require high costs and has the advantage of easy maintenance due to simple system configuration.

Through this demonstration, which also involves the Research Institute of Industrial Science & Technology (RIST), POSCO Energy would complete the verification of technology and economic efficiency by February 2022. Depending on the results of verification, the company will gradually enter markets where energy consumption is high.

Demands for energy recycling technologies to reduce carbon emissions at energy-multi-consumption sites are rapidly growing. POSCO Energy described waste heat generation as the most effective alternative for companies to practice carbon neutrality. "We will successfully promote the demonstration of waste heat generation to secure carbon emission reduction technologies at an early date," POSCO Energy President Chung Ki-sup was quoted as saying.
