DICE involves converting coal or biomass into a water-based slurry (called micronised refined carbon, MRC) that is directly injected into a large, specially adapted diesel engine. CSIRO is excited about the potential for DICE to lower power costs, halve carbon dioxide intensity and create a new export market for both brown and black coal.
Despite efforts to continue stimulating the US economy in the wake of the pandemic, high inflation put a damper on economic growth, which was exacerbated by a spike in oilprices as a result of Russia’s invasion of Ukraine. Outside of the power sector, emissions increased slightly. In 2022, emissions reached only 15.5%
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% Brent oilprices were on average 40% higher than 2010 and exceeded $100 a barrel for the first time ever; at $111.26/bbl,
The National Energy Technology Laboratory (NETL) has released a follow-on study to its 2009 evaluation of the economic and environmental performance of Coal-to-Liquids (CTL) and CTL with modest amounts of biomass mixed in (15% by weight) for the production of zero-sulfure diesel fuel. This equates to diesel prices in the range of $2.70
CO 2 per capita emissions from fossil fuel use and cement production from the top 5 emitting regions. Global emissions of CO 2 increased by 3% last year, according to the annual report “Trends in global CO 2 emissions”, released by the EC Joint Research Centre (JRC) and the Netherlands Environmental Assessment Agency (PBL).
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. Even with CCS, the liquid product costs are comparable to recent crude oilprices.
If current policy and technology trends continue, global energy consumption and energy-related carbon dioxide emissions will increase through 2050 as a result of population and economic growth. Oil and natural gas production will continue to grow, mainly to support increasing energy consumption in developing Asian economies.
Global CO 2 emissions from fossil-fuel combustion reached a record high of 31.6 Coal accounted for 45% of total energy-related CO 2 emissions in 2011, followed by oil (35%) and natural gas (20%). increase in CO 2 emissions in countries outside the OECD was only partly offset by a 0.6% Gt on 2010, or 3.2%.
The results of a new, comprehensive modeling study characterizing light-duty electric drive vehicle (EDV) deployment in the US over 108 discrete scenarios do not demonstrate a clear and consistent trend toward lower system-wide emissions of CO 2 , SO 2 , and NO x as EDV deployment increases. —Babaee et al.
Ceres recently released a new report concluding that coal-to-liquid (CTL) and oil shale technologies face significant environmental and financial obstacles—from water constraints, to technological uncertainties to regulatory and market risks—that pose substantial financial risks for investors involved in such projects.
Given current policies and regulations limiting fossil fuel use, worldwide energy-related CO 2 emissions rise from about 31 billion metric tons in 2010 to 36 billion metric tons in 2020 and then to 45 billion metric tons in 2040, a 46% increase over the 30-year span. Liquid fuels. trillion kilowatthours in 2010 to 5.5
Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., However, this only accounts for the processing that occurs in Canada and therefore excludes much of the refining and transport emissions.
In both the base-case and a scenario with more aggressive environmental policies, CO 2 emissions from energy use remain well above the IEA 450 scenario. However, both cases result in global CO 2 emissions well above the IEA 450 scenario—a back-cast which illustrates what is required to stabilize greenhouse gas concentrations at 450 ppm.
Removing fossil fuel subsidies would have only a small effect on CO 2 emissions and renewable energy use, according to a new study led by the International Institute for Applied Systems Analysis (IIASA) and published in the journal Nature. First, these subsidies generally apply only to oil, gas, and electricity. This equates to 0.5-2
However, the report advises, long-term solutions to global challenges remain scarce; as one example, the report sees global CO 2 emissions rising by 20% to 37.2 China is about to become the largest oil-importing country and India becomes the largest importer of coal by the early 2020s. Gt by 2035. —WEO-2013.
Normalized well-to-wake GHG emissions for low-, baseline- and high-emission cases for jet fuel pathways under different land use change scenarios. Canadian oil sands and Venezuelan VHOs have the largest potential of several hundred thousand barrels per day of jet fuel, but their use would result in increased GHG emissions.
World oilprices remain high in the IEO2011 Reference case, but oil consumption continues to grow; both conventional and unconventional liquid supplies are used to meet rising demand. In the IEO2011 Reference case the price of light sweet crude oil (in real 2009 dollars) remains high, reaching $125 per barrel in 2035.
Global CO 2 emissions from fuel use and cement production by region. Emissions increased by 1.7% Global CO2 emissions increased from 15.3 Fossil oil consumption decreased by one per cent, due to high prices and more biofuels. Source: PBL.

Dimethyl ether is a diesel fuel replacement that can be produced from abundant resources including natural gas, landfill methane, coal and biomass. At current oilprices, DME can be produced and distributed at less than 1/2 the cost of conventional fuel.
Projected growth in world carbon dioxide emissions. World carbon dioxide emissions are projected to rise from 29.0 The IEO2009 reference case does not include specific policies to limit greenhouse gas emissions. In 2006, non-OECD emissions exceeded OECD emissions by 14%. Source: IEO2009. Click to enlarge.
EIA also forecasts the Brent crude oilprice will average $64 per barrel this summer, a 78% increase from last summer’s average of $36 per barrel. That price increase paired with an increase in gasoline and diesel demand will likely increase the cost of regular gasoline and diesel fuel this summer. MMBtu in 2020 to $3.31/MMBtu
Base case economics for EVs in North America are very challenging, absent significant disruption in oilprice or battery cost. If there is insufficient low-carbon power-generation infrastructure, EVs will struggle to be seen as a solution for reducing carbon emissions significantly. Click to enlarge.
Lifecycle GHG emissions of CTL/CBTL/BTL compared to 2005 petroleum diesel baseline. Background colors of the cells represent the crude oilprice required for economic feasibility. Adding biomass to the coal in the CTL process (Coal and Biomass to Liquids, CBTL) can reduce the GHG emissions further, according to the study.
The transportation sector thus represents a significant fraction of total greenhouse gas (GHG) emissions both globally and in the US—light-duty vehicles (LDVs) are responsible for 17.5% of carbon dioxide (CO 2 ) emissions in the US. The analogous progression for CO 2 emissions is less clear. Vehicle technologies.
A new study by researchers at the University of Colorado at Boulder projects the emission impacts of the widespread introduction of inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. Total NO x , VOCs, and SO 2 emissions are similar in OPT and BAU due to inter-sectoral shifts. Click to enlarge.
The study, in press in the Journal of Power Sources , examines the efficiency and costs of current and future EVs, as well as their impact on electricity demand and infrastructure for generation and distribution, and thereby on GHG emissions. Derive GHG emissions and costs of charging of EVs in the 2015 Dutch context and. We therefore.
World production of fossil fuels—oil, coal, and natural gas—increased 2.9% million tons of oil equivalent (Mtoe) per day, according to a Worldwatch Institute analysis. Coal has led the growth in fossil fuel production. In 2000, coal provided 28% of the world’s fossil fuel energy production, compared with 45% for oil.
EIA added a premium to the capital cost of CO 2 -intensive technologies to reflect current market behavior regarding possible future policies to mitigate greenhouse gas emissions. In recent years, the US electric power sector’s historical reliance on coal-fired power plants has begun to decline.
Greenhouse gas (GHG) emission standards and CAFE standards increase new LDV fuel economy through model year 2025 and beyond, with more fuel-efficient new vehicles gradually replacing older vehicles on the road and raising the fuel efficiency of the LDV stock by an average of 2.0% per year, from 21.5 l/100 km) in 2012 to 37.2 Tcf in 2012 to 2.1
However, given the ongoing reliance on fossil fuels, the emissions in the New Policies Scenario correspond to a long-term average global temperature increase of 3.6 °C. barely rises in OECD countries, although there is a pronounced shift away from oil, coal (and, in some countries, nuclear) towards natural gas and renewables.
Energy efficiency improvements and the increased use of renewables are other key factors that moderate the projected growth in energy-related greenhouse gas emissions. Assuming no changes in policy related to greenhouse gases, carbon dioxide emissions grow slowly, but do not again reach 2005 levels until 2027. Transportation updates.
Biofuels grow at a slower rate due to lower crude oilprices and. The decline reflects increased domestic production of both petroleum and natural gas, increased use of biofuels, and lower demand resulting from the adoption of new vehicle fuel efficiency standards and rising energy prices. Biomass and biofuels growth is slower.
Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO 2 emissions to a new high. Short-term pressures on oil markets are easing with the economic slowdown and the expected return of Libyan supply.
AEO2015 presents updated projections for US energy markets through 2040 based on six cases (Reference, Low and High Economic Growth, Low and High OilPrice, and High Oil and Gas Resource) that reflect updated scenarios for future crude oilprices. trillion cubic feet (Tcf) in the Low OilPrice case to 13.1
California’s LCFS also would have little or no impact on GHG emissions nationwide and would harm our nation’s energy security by discouraging the use of Canadian crude oil—our nation’s largest source of crude—and ethanol produced in the American Midwest. The LCFS is an ineffective tool for reducing GHG emissions.
The underlying assumption is that the world will immediately use whatever oil can be pumped from the ground, and that supply is independent of demand—that is, oil exploration investments bear no relation to the current oilprice or expectations of future demand. Emissions Forecasts Fuels Oil'
Energy efficiency has tremendous potential to boost economic growth and avoid greenhouse gas emissions, but the global rate of progress is slowing, according to a new report by the International Energy Agency. Oil represented the largest share of final demand, at around 41%, but demand growth slowed to 1.5%
For example, at peak oilprice in 2008, Indonesia was spending 40% of its budget on transport fuel—more than health, education and infrastructure development combined. ” Some of the main lessons drawn from the report include: Fossil-fuel subsidies absorb serious amounts of money.
Finally, DOE will support development of domestically produced, infrastructure-compatible biofuels to reduce carbon emissions from liquid transportation fuels where electrification is not viable (heavy-duty vehicles, marine, and air). fleets).
From this solid foundation, we proceed to the second mammoth task these days: the development of alterative, emissions-free drives. With electromobility, the automobile industry faces a fundamental technological upheaval.Our path leads away from oil, to emission-free mobility, and the electric car plays a key role.CO
Heavy fuel oil (HFO) is the predominant marine fuel. Because of its high sulfur content, maritime shipping accounts for 8% of global emissions of sulfur dioxide (SO 2 ), making the industry an important source for acid rain as well as respiratory diseases. It is viscous, dirty, inexpensive and widely available.
The report, “ Renewable Power Generation Costs in 2014 ”, concludes that biomass, hydropower, geothermal and onshore wind are all competitive with or cheaper than coal, oil and gas-fired power stations, even without financial support and despite falling oilprices.
With oilprices surging in the summer of 2008, the annual increase in global emissions of carbon dioxide (CO2) from oil, coal, gas and cement production appear to have halved according to preliminary estimates by the Netherlands Environmental Assessment Agency. per cent in 2008, compared to 3.3 per cent in 2007.
If the US military increases its use of alternative jet and naval fuels that can be produced from coal or various renewable resources, including seed oils, waste oils and algae, there will be no direct benefit to the nation’s armed forces, according to a new RAND Corporation study. ” —James Bartis, lead author.
