KEPCO Develops sf 6 Recycling Device to Combat Greenhouse Gas

Korea Electric Power Corp. (KEPCO) announced on July 9 that it has developed a sulfur hexafluoride (insulating gas) refining device which recycles sf6 gas emissions from discarded shutters and transformers. Sulfr hexafluoride is a greenhouse gas whose global warming effects are 23,900 times those of carbon dioxide. sf 6 is used as an insulation material for high voltage power equipment due to its electrical insulation property.

Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago. Plus, improvements in the energy intensity of the global economy (the amount of energy used per unit of economic activity) are slowing.

The Carbon Brief Profile: South Korea

PoliticsParis Pledge‘Green Growth’ Policies‘New and Renewable’ EnergyNuclearCoalTransportIndustryImpacts and AdaptationSince the hostilities of the Korean War ended in 1953, the Republic of Korea – one of the “four Asian tigers” – has grown from a developing country into a significant economic power with the 12th-highestGDP in the world. In particular, it has become known as a major exporter and an industrial leader in many sectors, including electronics, cars, shipbuilding and steel. Following decades of authoritarian rule, South Korea held its first free parliamentary election in 1988. Its two major political parties are the conservative United Future Party and the ruling liberal Democratic Party, with Moon Jae-inserving as the nation’s current Democratic president. The next legislative election, in which all 300 members of the country’s national assembly will be chosen, is set to take place on 15 April. Not only will this election be the first since the Korean voting age was lowered from 19 to 18, it will also see some politicians elected via proportional representation for the first time, potent...

Atmospheric Sulfr hexafluoride: Trends, Sources, and Prospects

Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, sf6 gas will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought sf 6 into the climatic impact discussion aimed at reduction

The EPA does no t report emission of sf6 gas separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and gaz sf6. The emissions of HFCs, PFCs, and sf6 gas for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.

The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases). (Draft estimates for emissions of HFC and PFC substitutes for ozone-depleting substances in 2009 are included; 2008 data are used for emissions of other high-GWP gases.)
