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.

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).

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

The RBAEF project, which was launched in 2003, is the most comprehensive study of the performance and cost of mature technologies for producing energy from biomass to date. The emissions analysis does not account for carbon sinks (e.g., soil carbon sequestration) or sources (e.g., per liter gasoline equivalent ($1.37 – $2.16

IEA World Energy Outlook view on the transport sector to 2035; passenger car fleet doubling to almost 1.7B units, driving oil demand up to 99 mb/d; reconfirming the end of cheap oil

Green Car Congress

Alternative technologies, such as hybrid and electric vehicles that use oil more efficiently or not at all, continue to advance but they take time to penetrate markets. Without a bold change of policy direction, the IEA warned at the launch, the world will lock itself into an insecure, inefficient and high-carbon energy system.
