Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015) While the increases in PM 10 and PM 2.5

US greenhouse gas emissions by gas. The US Environmental Protection Agency (EPA) released its 19 th annual report of overall US greenhouse gas (GHG) emissions, showing a 3.4% decrease in 2012 from 2011. Total emissions of the six main greenhouse gases in 2012 were equivalent to 6,526 million metric tons of carbon dioxide.

Among the findings of the EIA analysis: CO 2 emissions form natural gas surpassed those from coal in 2016. Natural gas CO 2 emissions have increased every year since 2009. These emissions were highest in 2007, prior to the recession, and have not returned to those levels, despite increasing every year since 2012.

seen in 2010, according to the newly released BP Statistical Review of World Energy, 2012. Oil demand grew by less than 1%—the slowest rate amongst fossil fuels—while gas grew by 2.2%, and coal was the only fossil fuel with above average annual consumption growth at 5.4% more as natural gas was diverted to Asia.
