The Seoul city government will start constructing a hydrogen-fired power plant in World Cup Park in Seoul next May.

The 2.4 mega watt facility will generate electricity with hydrogen extracted from oil and gas. Such a method is considered environmentally friendly for emitting no sulfur oxide and other harmful chemicals.

A ``Zero-Energy House,'' where solar power and other environmentally friendly energies are used, as well as other power generation facilities using solar power and other ``green energy'' will be set up in the park. The city plans to promote the area as a landmark for next generation renewable energy.

The city plans to replace 10 percent of its energy consumption with renewable energy by 2020, of which 30 percent will be from hydrogen.
