Chairman Park Gee-won of Doosan Heavy Industries and Construction Co.

Doosan Heavy Industries and Construction Co. has decided to stick with environmentally friendly energy technologies to find its future growth engines in line with the Doosan Group’s firm decision.

Doosan Heavy has been managing the sea wind power and coal gasification businesses with green energy technologies in line with the group’s master plan. The company developed the “WinDS3000,” a sea wind power generation system, and installed the system in the Gimnyumpoku area in Jeju City on Jeju Island in 2009, the initial step in its quest for green energy projects. Energy sources said the world sea wind power system industry is projected to grow an average of 30 percent annually in the future with the projected total sea wind power output to rise from 4 GW now to 99GW in 2025.

Doosan Heavy, in a joint endeavor with the Ministry of Knowledge Economy and the Korea Energy Technology Evaluation Institute, installed a 3 Mw-class sea wind power system on the sea coast some 1.5 km from Woljong-ri, Kujwa County, Jeju Island, in July 2012, which is equivalent to 60 percent of the world sea wind power market.

Only a few power companies in the world operate sea wind power systems including Vestas of Denmark and Siemens of Germany, and of further significance is the fact that Doosan Heavy developed the system on its own, energy sources said.

The WinDS3000 System has a built-in crane so the system can be repaired easily at sea and it can withstand winds of up to 70 meters per second in power.

Doosan Heavy won international confirmation from Germany’s ‘DEWI-CCC’ and clinched a land wind power plant project with the capacity of 24 Mw from Korea Southeast Power Co. last year.

Doosan Heavy plans to enter the world sea wind power system market with its WinDS300 Sea Wind Power System technologies, targeting the United States and Europe, leading regions in the wind power generating systems, to spur its growth enough to rank among the leading global wind power generation systems makers.

A huge advantage for Doosan Heavy has been that the company began the joint development of various parts of the wind power system with other companies such as KM for rotor blades, and Dongkuk S&C for towers, as well as other suppliers for power generators and accelerators, all told 70 percent of the parts for the wind power system are provided by domestic makers.

 Doosan Heavy has been working on coal gasification power plants (IGCC) with the company signing an agreement with Korea West Power Co. to build a coal gasification plant valued at 513.2 billion won to be completed in 2015.

A coal gasification plant retrieves gas mixed with hydrogen and carbon monoxide from coal and generates power with it as fuel, which is regarded as an environmentally clean power plant compared with a power plant burning coal because it does so without coal ash, toxic gas such as carbon monoxide, and other pollutants. The coal gasification plant requires a high level of technologies and there are only five such plants in operation in the world today.

Coal is abundant around the world and much cheaper than oil, providing a huge advantage for the development of the IGCC business. It is projected that coal gasification plants will grow as much as 1,200 trillion won in value by 2030.

Doosan Heavy officials said when the current coal gasification plant project turns out to be a success, they expect its demand will grow enormously not only at home but also overseas and they see themselves as the firm that will develop it further as the company’s next future growth engine.
