Study finds that dry-feed gasification for coal-to-liquids is more efficient, lower-emitting and cheaper than slurry-feed; CCS cost-effective for reduction of CO2

Green Car Congress

Comparison of coal consumption and CO 2 emissions for co-production and separate production of liquids and power. Plant-level CO 2 emissions can be greatly reduced by using the CCS technology, the study found, without much increase in capital cost. Even with CCS, the liquid product costs are comparable to recent crude oil prices.

ICCT updates US airline fuel efficiency rankings; Alaska stays on top, American on bottom

Green Car Congress

This approach, ICCT says, enables an equitable comparison of airline fuel efficiency, regardless of business model, through the use of primary fuel burn data and an inclusive metric for transport service—a combination of mobility, measured by revenue passenger miles (RPM), and access, measured by departures (or the flight frequency).

Study Finds Integrated Biorefinery Processes Could Be Highly Competitive With Petroleum Fuels on Efficiency and Costs, While Offering Substantial Reductions in Greenhouse Gas Emissions

Green Car Congress

integrating biological and thermochemical processing to produce biofuels and/or power could offer similar, if not lower, efficiencies and costs and very large reductions in greenhouse gas emissions compared to petroleum-derived fuel, according to a comparative analysis of 14 mature technology biomass refining scenarios.

Background colors of the cells represent the crude oil price required for economic feasibility. These synthetic fuels are economically competitive with petro-diesel when the crude oil price (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).

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. by Brian J.
