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

A co-production scenario—yet to be commercial—would take unconverted syngas from the FT reactor and combust it in a combined cycle power plant to generate electricity that is sold to the grid. Even with CCS, the liquid product costs are comparable to recent crude oil prices. Source: Mantripragada and Rubin.

Annual Increase in Global CO2 Emissions Halved in 2008; Decrease in Fossil Oil Consumption, Increase in Renewables Share

Green Car Congress

In addition to high oil prices 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.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz presented the paper at the 10 th International Conference on Greenhouse Gas Control Technologies ( GHGT-10 ) earlier this fall in The Netherlands. Over time, however, as the CO 2 price increases, it eventually becomes more economical to either retrofit plants to capture and store most of. their CO 2 (e.g. ~90%)

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.

Study Finds Coordinated Off-peak Charging Can Support Large Scale Plug-in Use Without Additional Generation Capacity; TCO and GHG Abatement Costs for BEVs Projected to Remain High

Green Car Congress

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 oil price of US$80/bbl, close to the short-term.
