New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems.

DOE and Air Force issue RFI on Mil-Spec jet fuel production using coal-to-liquid technologies

Green Car Congress

The US Department of Energy (DOE) in partnership with the US Air Force has issued a request for information (RFI)— DE-FOA-0000981 —on research & development aimed at greenhouse gas emissions reductions and cost competitiveness of Mil-Spec jet fuel production using coal-to-liquid (CTL) fuel technologies. Information Request.

EIA: US energy-related CO2 emissions in 2012 lowest since 1994; reflects drop in coal use

Green Car Congress

With the exception of 2010, emissions have declined every year since 2007. The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. The regulations would make 65% of coal plants nationwide as expensive as natural gas, even if gas prices rise significantly.

Alaska Native Corporation Proposes Underground Coal Gasification Project with Carbon Capture for Power Generation

Green Car Congress

Underground coal gasification uses paired wells in a coal seam: one an oxidant injection well, the other the syngas producer well. CIRI), an Alaska Native corporation, is proposing an underground coal gasification (UCG) project that would use the resulting syngas to fuel a new 100 MW combined cycle power plant. Source: CIRI.

EIA: US energy-related CO2 emissions down 1.7% in 2016; carbon intensity of economy down 3.1%; transportation emissions up

Green Car Congress

These contributing factors included a decline in the carbon intensity of the energy supply (CO 2 /British thermal units [Btu]) of 1.7% Combining these two factors, the overall carbon intensity of the economy (CO 2 /GDP) declined by 3.1%. Although real gross domestic product (GDP) increased 1.5% along with a 1.4%

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. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide. Process flow diagram.

EIA: CO2 emissions from US power sector have declined 28% since 2005

Green Car Congress

Source: US EIA, US Energy-Related Carbon Dioxide Emissions , 2017. 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.
