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. Earlier post.). —White and Gray.
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.
Australia’s Syngas Limited has engaged Rentech to provide Fischer-Tropsch fuels production preliminary engineering services for Syngas’ proposed commercial scale coal and biomass to liquids (CBTL) fuels facility in Southern Australia, known as the Clinton Project. Additionally, the Clinton coal fluidizes well.
The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. million bpd. For CTL, life-cycle GHG emissions would roughly double.
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.
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.
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.
With prices expected to increase in the long term, however, the world oilprice in real 2011 dollars reaches $106 per barrel in 2020 and $163 per barrel in 2040, according to IEO2013. Biomass Climate Change Coal-to-Liquids (CTL) Emissions Forecasts Fuels Gas-to-Liquids (GTL) Market Background'
The break-even crude oilprice for a delivered biomass cost of $94/metric ton when hydrogen is derived from coal, natural gas or nuclear energy ranges from $103 to $116/bbl for no carbon tax and even lower ($99–$111/bbl) for the carbon tax scenarios. Their analysis is published in the journal Biomass Conversion and Biorefinery.
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. They assumed an oilprice of US$80/bbl, close to the short-term.
Background colors of the cells represent the crude oilprice required for economic feasibility. These synthetic fuels are economically competitive with petro-diesel when the crude oilprice (COP) is at or above $86 per barrel (based on a 20% rate of return, in January 2008 dollars, with a carbon price of zero).
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
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. Historical scenario. (A)
Bartis and RAND colleague Lawrence van Bibbe were the authors of a 2011 RAND report concluding that if the US military increased 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 would be no direct benefit to the nation’s armed forces.
About 60-80% of full life cycle emissions result from driving/operating a vehicle; if only the extraction emissions (WTT) are examined, oil sands will deliver a relatively high value. Yet, coal-fired emissions in Alberta receive relatively little attention from environmental organizations and the public.
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. million tonnes in 2050, due to existing control requirements and the shift away from coal-fired generation.
With the release, MITEI cautioned that the report is not a study. Electrification will also reduce oil dependence, providing foreign policy benefits and the potential to reduce real oilprices and oilprice volatility. Vehicle technologies. —Deutch and Moniz.
In addition to high oilprices and the financial crisis, the increased use of new renewable energy sources, such as biofuels for road transport and wind energy for electricity generation, had a noticeable and mitigating impact on CO 2 emissions. Coal consumption: lower increase due to financial crisis and more renewable electricity.
Now, a study commissioned by the US Energy Information Administration (EIA) from eia.gov (a global provider of analysis on energy and commodities), finds that since the early 2000s, China’s consumption of methanol in fuel products has risen sharply. Source: EIA and Argus Media group, China Methanol to Energy Study , January 2017.
The WEO analysis includes three global scenarios and multiple case studies: The New Policies Scenario—the central scenario for this WEO—assumes recent government policy commitments will be implemented in a cautious manner, even if they are not yet backed up by firm measures. —WEO 2011.
