NOAA greenhouse gas index continues climbing; 1.29 in 2010

Green Car Congress

in 2010—i.e., the combined heating effect of long-lived greenhouse gases added to the atmosphere by human activities has increased by 29% since 1990, the index year used as a baseline for comparison. Started in 2004, the AGGI reached 1.29 This is slightly higher than the 2009 AGGI, which was 1.27—i.e., —i.e.,

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.

Consumption-based power mixes and NG transmission distances by Chinese province in 2010. In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology.

CERA: Canadian Oil Sands Poised to Become the Top Source of Crude Imports to the US in 2010; Could Contribute Up To 36% of US Oil and Refined Products Imports by 2030

Green Car Congress

Growth of production of Canadian oil sands. The Canadian oil sands are now poised to become the number one source of US crude oil imports in 2010, according to new research from the IHS CERA Canadian Oil Sands Dialogue. The Role of Canadian Oil Sands in US Oil Supply”. Conventional oil uses 0.1

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. 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 oil prices.

New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

Comparison of relative contributions from various sources to total BC emissions between China and other countries/regions including India, North America, and Africa. In addition, predicted oil consumption for use in motor vehicles between 2008 and 2050 were used to develop the inventory. Earlier post.). Credit: ACS, Wang et al.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. Solid arrows: Pyrolysis oil is directly passed over the zeolite catalyst.
