Information Request.
Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. In both plants, natural gas turbines power the equipment.
Aviation climate change impacts pathway. An an example, they point out that an SPK fuel option with zero life cycle GHG emissions would offer a 100% reduction in GHG emissions but only a 48% reduction in actual climate impact using a 100-year time window and the nominal climate modeling assumptions in the paper.
Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change.
Petroleum emissions from other sectors have fallen in recent years as equipment and processes that use petroleum fuels have been replaced by those using other fuels, in particular, natural gas. Natural gas is the least carbon-intensive fossil fuel, and for decades natural gas made up the smallest portion of US energy-related CO 2 emissions.
The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown.
