New & Renewable Energy

The new & renewable energy source is utilized for the integrated energy projects to cope with the climate change crisis related to the greenhouse gas emission which is the global issue.

The new & renewable energy means the eco-friendly, non-depletable energy such as sunlight and wind that can replace the fossil fuel such as oil, coal and natural gas. Countries all over the world are investing heavily on utilization of the new & renewable energy to diversify the energy source to prepare for depletion of fossil fuel and to reduce greenhouse gas emission. Korea is also mandating the power plants owning the power generator with total capacity of 500MW or more (excluding the capacity of the power generators using the new & renewable energy) to use the new & renewable energy for a specific portion or more of total power generation in order to promote the distribution of new & renewable energy.

To be in step with such global trend and government policy, KDHEC has been accumulating the project experience and specialized know-how of power generation using new & renewable energy.

Fuel Cell

A fuel cell is a device which utilizes the electrical and thermal energy generated by continuous reaction of the oxygen ions in the fuel and oxygen ions in the air. It is a way of eco-friendly and highly efficient power generation with very little atmospheric pollution and noise generation. As such, its application is being expanded worldwide.

Solid Fuel (SRF or Bio-SRF)
Utilization

The technology obtains both thermal energy and electrical energy by burning solid fuel generated by a preprocessing facility (MBT) to turn the food waste and municipal into fuel. The boiler using SRF or bio-SRF can be designed for high efficiency power generation, improved exhaust gas property, and reduced dioxin.

Landfill Gas (LFG)
Utilization

The technology captures the methane gas generated by decomposition of various organic matters in the landfill and uses it as the fuel for power generator to recover the thermal energy and electrical energy.

Heat Pump

A heat pump is a device that converts the thermal energy such as geothermal, river water and seawater, which are scattered widely at low temperature thus difficult to be used directly, into the high temperature, concentrated thermal energy. It usually converts low temperature to high temperature or high temperature to low temperature for heating/cooling or supply hot water. It is notable for the ability to cool and heat at the same time.

Solar Photovoltaic
Power Generation

It uses a solar cell which directly converts the photovoltaic energy to electrical energy to generate the power to be supplied to consumers.

Solar Heat
Power Generation

It uses the solar collectors (mirrors) to collect the solar heat energy into a point and uses it to generate the high temperature steam to operate the steam turbine and generate the electricity.

Wind Power Generation

It uses a wind turbine to convert the wind energy into mechanical energy and then uses it to rotate the power generator to produce the electricity. In Korea, the wind farms are in operation in Daegwallyeong and Jeju Island, and a offshore wind power testing complex is being built in the southwestern sea.

Integrated Gasification
Combined Cycle (IGCC)

It partially burns the coal at high temperature and high pressure to produce the synthetic gas (CO2+H2) and uses it as fuel in the combined cycle power plant. The produced synthetic gas is used to operate the gas turbine while the thermal energy of exhaust gas of the gas turbine is recovered using the heat recovery steam boiler. The produced steam operates the steam turbine. The new concept power generation combines the conventional coal-fired thermal power plant, chemical plant and combined cycle thermal power plant. The technology is popular in developed countries as it is effective in reducing greenhouse gas emission to cope with climate change.
