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.
US electric power sector CO 2 emissions have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity, according to the US Energy Information Administration (EIA). If electricity demand had continued to increase at the average rate from 1996 to 2005 (1.9%
Increased economic activity and a changing fuel mix in the electric power sector in 2021 will lead to a significant increase in energy-related carbon dioxide emissions this year, according to the US Energy Information Administration’s (EIA) August Short-Term Energy Outlook (STEO). billion metric tons this year. billion metric tons this year.
billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. Coal accounted for over 40% of the overall growth in global CO 2 emissions in 2021, reaching an all-time high of 15.3 billion tonnes. billion tonnes.
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.
This FOA, issued in August 2017, is a $50-million funding opportunity for projects supporting cost-shared research and development to design, construct, and operate two large-scale pilots to demonstrate transformational coal technologies. General Electric. Organization. Description. Babcock & Wilcox Company. University of Illinois.

In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. The United States now emits less CO 2 from coal than from motor gasoline. Total net electricity generation fell by 1.5%
EIA’s Annual Energy Outlook 2014 (AEO2014) features several accelerated retirements cases that represent conditions leading to additional coal and nuclear plant retirements in order to examine the potential energy market and emissions effects of the loss of this capacity. Coal generation does not differ significantly between the two cases.
The US Department of Energy (DOE) selected eight projects to advance the development of transformational oxy-combustion technologies capable of high-efficiency, low-cost carbon dioxide capture from coal-fired power plants. Gas Technology Institute. Babcock & Wilcox Power Generation Group.
Comparison of coal consumption and CO 2 emissions for co-production and separate production of liquids and power. Conventional CTL plant gasifies coal to produce a syngas which is then converted in a Fischer-Tropsch reactor to products. The liquids output capacity of CTL plants is 50,000 barrels/day. Source: Mantripragada and Rubin.
The issue here is whether restructuring the Nation’s overall mix of electricity generation, to transition from 38% coal to 27% coal by 2030, can be the “best system of emission reduction” within the meaning of Section 111. Under our precedents, this is a major questions case. . … For the reasons given, the answer is no.
The TCEP would integrate coal gasification, combined-cycle power generation, CO 2 capture, and. We now have sales commitments in place for all three of TCEP’s main commercial products—electric power, urea for fertilizer, and CO 2 for enhanced oil recovery—and that is obviously key to getting this project underway.
Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase. The use of liquids declines in the other end-use sectors and for electric power generation. Electricity generation from nuclear power worldwide increases from 2.6
Arizona Public Service’s ongoing algae-based carbon mitigation project, previously selected via competitive solicitation, will be expanded to include testing with a coal-based gasification system. The process aims to minimize production of carbon dioxide when gasifying coal. Funding for the project expansion falls under the ARRA’s $1.52
has been chosen to provide the coal gasification technology for the Taylorville Energy Center (TEC), a 730-megawatt (gross) advanced coal generating plant being developed near Taylorville, Ill. TEC will be one of the first commercial-scale, coal gasification plants with carbon capture and storage (CCS) capability in the US. .
The United States remain one of the largest emitters of CO2, with 17.3 tonnes per capita, despite a decline due to the recession in 2008-2009, high oil prices and an increased share of natural gas. Natural gas consumption increased globally by 2.2% Coal consumption in China increased by 9.7% tonnes per capita.
By using a new, innovate manufacturing process, the production of steel at the supplier level is CO2 free. In the new process, the supplier uses hydrogen and electricity from 100% renewable energy sources instead of coking coal in steel production. Unlike the use of coking coal, this does not produce CO 2 , but water.
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.
Natural gas accounts for the second-largest share of energy-related US CO 2 emissions, at 33% of the 2019 total. Compared with petroleum and coal, EIA expects a relatively smaller decline in natural gas consumption and its related CO 2 emissions (both 4% lower) in 2020.
Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT.
The US Department of Energy’s (DOE) Office of Fossil Energy (FE) has selected four projects for cost-shared research and development under the funding opportunity announcement (FOA), DE-FOA-0002180, Design Development and System Integration Design Studies for Coal FIRST Concepts.
Production of cement accounts for 5-6% of all anthropogenic CO 2 emissions, generating 9 kg of the greenhouse gas for each 10 kg of cement produced, notes Dr. Stuart Licht and his colleagues in a paper on their process accepted for publication in the RSC journal Chemical Communications. —Licht et al. used three.
The US and China jointly announced greenhouse gas (GHG) reduction targets. US President Barack Obama said the US will cut net greenhouse gas emissions in the US by 26-28% below 2005 levels by 2025. Together, the US and China account for more than one third of global greenhouse gas emissions.
A pilot project by We Energies, Alstom and The Electric Power Research Institute (EPRI) testing an Alstom advanced chilled ammonia process ( earlier post ) has demonstrated more than 90% capture of carbon dioxide from the flue stream of a coal-fueled power plant in Wisconsin (the Pleasant Prairie Carbon Capture Pilot Plant ).
MHI) and Southern Company, a major US electric utility, has begun underground injection of CO 2 recovered from emissions from a coal-fired power generation plant. The facility consists primarily of a flue-gas scrubber, flue-gas CO 2 capture/re-generation system, CO 2 compression machinery, and electrical components.
The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. The EIA projects that fuel switching in the electric power sector and declines in industrial use will lead to a 7.9% Natural Gas.
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.
Global CO 2 emissions from fossil fuel use and cement production reached a new all-time high in 2013, according to the annual report “Trends in global CO2 emissions”, released by PBL Netherlands Environmental Assessment Agency and the European Joint Research Centre (JRC). The much lower emissions increase in China of 4.2% in 2013 and 3.4%
This was the result of growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, as well as structural changes in the global economy. The decline was driven by a surge in shale gas supplies and more attractive renewable power that displaced coal.
Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Gas demand growth was especially strong in the United States and China. Still, that was not fast enough to meet higher electricity demand around the world that also drove up coal use.
The strategy is centred around two main technology routes, as introduced in the first ArcelorMittal Europe climate action report published earlier this year: The use of hydrogen in DRI-EAF (Direct Reduced Iron - Electric Arc Furnace) and, also, the blast furnace. The expansion of its Smart Carbon route, also utilizing hydrogen.
Net emissions resulting from the use of plug-in hybrid electric vehicles (PHEVs) depend on the efficiency of the conventional vehicle fleet; PHEV CD (all-electric, charge-depleting mode) efficiency; charging strategy; battery pack capacity; driving patterns; and generator mix used for charging. —Peterson et al. Peterson, J.
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. of electric vehicle sales in the US. of sales.
The US Environmental Protection Agency (EPA) has proposed the first Clean Air Act standard for CO 2 greenhouse gas (GHG) emissions from new power plants. Although emissions vary by plant and with the specific type of fuel, EPA provided illustrative examples of CO 2 emissions from EGUs: Conventional coal: 1,800 lbs CO 2 /MWh.
The system also holds the potential to reduce the cost of producing chemicals, transportation fuels, and substitute natural gas from gasified coal. DOE and RTI will design, build, and test a warm gas cleanup system—based on RTI’s high-temperature syngas cleanup technology—to remove multiple contaminants from coal-derived syngas.
This would tend to put upward pressure on electricity demand and related emissions. A carbon intensity decline in the electric power sector (-4.0%) which accounted for 40% of total U.S. and 3.2%, respectively) as these sectors rely heavily on electricity to meet their energy needs.
Trestle and Larksen’s integrated approach furthers ethanol producers’ ability to scale up production of low carbon biofuels and allows existing power plants to generate electricity with the cost and reliability of coal and with carbon emissions similar to wind.
Converting CO 2 into a renewable energy sources would involve capturing the gas from the smokestacks of coal-fired electric power generating stations, for instance, and processing it with catalysts or other technology into fuels and raw materials for plastics and other products. ACS is the world’s largest scientific society.).
A computational analysis that screened hundreds of thousands of zeolite and zeolitic imidazolate framework structures has identified many different structures that have the potential to reduce the parasitic energy loss of carbon capture technologies for powerplant flue gas by as much as 30–40% compared with amine scrubbing. —Lin et al.
