OREANDA-NEWS. Doosan Heavy Industries & Construction (Chairman & CEO Geewon Park) has secured power generation technology using supercritical carbon dioxide and sets to commercialize it. The new technology offers higher energy efficiency with smaller equipment than existing solutions. The company announced on June 11 that it signed the supercritical CO2 Waste Heat Recovery Technology License Agreement with the US-based Echogen Power Systems.

Echogen Power Systems is the leader in this field and have succeeded in the demonstration test of the 7MW class supercritical CO2 heat engine for the first time in the world.

While existing power generation technologies produces electricity by running a turbine with high-temperature and high-pressure steam, the supercritical CO2-based power cycle can run a turbine by heating carbon dioxide.

The breakthrough sCO2-based power cycle has a wide range of advantages – as CO2 reaches its supercritical state at moderate conditions, high energy efficiency can be achieved.
Also electricity may be generated with more compact equipment, which results in lowering operating costs. Moreover, CO2 will cause less corrosion than steam, which will improve the durability of the turbine.

Supercritical CO2 power solutions can be used in various industrial applications, and especially have attracted attention for industrial plants such as cement and steel, where waste heat can be utilized and converted to electricity.

Yong-Jin Song, Head of Strategy & Business Development at Doosan said, “The global market is estimated at two trillion won (US\\$1.8 billion) per year based on power equipment in the cement, steel, and plant sectors combined. We are aiming to achieve more than 100 billion won (US\\$89.96 million) in annual sales.”
