EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 In 2011, CH4 emissions from coal mining were 63.2

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. If biogas is substituted for conventional natural gas, total GHG emissions can further significantly reduced (190 gCO 2 /mile). Lifecycle GHG comparison.

EPA: US greenhouse gases up 2% in 2013; increased coal consumption, cool winter

Green Car Congress

The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. Commercial aircraft emissions increased slightly between 2012 and 2013, but have decreased 18% since 2007.

EPA: US GHG emissions in 2017 down 0.3% from 2016

Green Car Congress

The decrease in CO 2 emissions from fossil fuel combustion was a result of multiple factors, including a continued shift from coal to natural gas, increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use. above 1990 levels in 2007. below 2005 levels.

BNEF: Oil price plunge to have only moderate impact on low-carbon electricity development, but likely to slow EV growth

Green Car Congress

With wind and even solar power increasingly competitive with coal and natural gas without subsidies, with many utilities needing to meet renewable portfolio standards, and with new EPA rules forcing coal plant retirements, the impact of lower oil prices on renewable energy in the US is expected to be insignificant.

Alabama Project Testing Potential for Combining CO2 Storage with Enhanced Methane Recovery

Green Car Congress

The targeted coal seams are in the Pratt, Mary Lee, and Black Creek Coal groups within the upper Pottsville Formation and range from 940 to 1,800 feet in depth and from 1 to 6 feet in thickness. Coal in the Black Warrior Basin has the potential to sequester 1.1 trillion cubic feet of natural gas from these coal seams.
