Texas utility signs first US Power Purchase Agreement for low-emissions electricity from commercial-scale coal-fired power plant with carbon capture

Green Car Congress

The agreement marks the first US purchase by a utility of low-carbon power from a commercial-scale, coal-based power plant utilizing carbon capture. Gasification uses oxygen and steam at high pressures to convert coal into syngas, which is mainly a mixture of hydrogen and carbon monoxide. Of the nearly 2.9

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

Green Car Congress

The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. During 2012, particularly in the spring and early summer, low natural gas prices led to competition between natural gas- and coal-fired electric power generators.

Duke study finds China’s synthetic natural gas plants will have heavy environmental toll; 2x vehicle GHG if used for fuel

Green Car Congress

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.

Berkeley study finds renewable portfolio standards insufficient to meet 2030 GHG emission targets; new policy required

Green Car Congress

One possible scenario for the electricity system in the Western US in 2026-29. Pie charts show the proportion of different types of energy sources generating power and flowing between load areas if there were a carbon tax of $70 per ton. To meet these carbon goals, coal has to go away from the region. Click to enlarge.

would be designed to capture up to 90% of its carbon dioxide for enhanced oil recovery and sequestration in an adjacent oil field. In 2007, GE and BP formed a global alliance to jointly develop and deploy technology for at least five IGCC power plants that could significantly reduce carbon dioxide emissions from electricity generation.

DOE to Award $106M to Six CO2 Conversion Projects; $156M in Matching Private Funding

Green Car Congress

The US Department of Energy has selected six projects for funding that aim to find ways of converting captured carbon dioxide emissions from industrial sources into useful products such as fuel, plastics, cement, and fertilizers. The project team plans to process CO 2 -laden flue gas from a Capital Aggregates, Ltd.

EPA proposes CO2 emission standards for new fossil fuel-fired power plants

Green Car Congress

The US Environmental Protection Agency (EPA) has proposed Clean Air Act standards to reduce CO 2 emissions from fossil-fuel fired power plants (electric utility generating units, EGUs). The proposed rulemaking establishes separate standards for natural gas and coal plants. 1,100 lb CO 2 /MWh-gross over a 12-operating month period; or.
