IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The global energy supply became 6% cleaner from 1971 to 1990,in response to the oil shocks of the 1970s. In 1990 the underlying carbon intensity of supply was 57.1 The world must slow the growth of energy demand as well as make its energy supply cleaner, the IEA said. tCO 2 /TJ (2.39 tCO 2 /toe); in 2010 it was 56.7

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

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. emissions are less important because of the low contribution of light duty vehicles to national PM 10 and PM 2.5

SGH2 building largest green hydrogen production facility in California; gasification of waste into H2

Green Car Congress

The City of Lancaster will supply guaranteed feedstock of recyclables, and will save between $50 to $75 per ton in landfilling and landfill space costs. It also solves our plastics and waste problems by turning them into green hydrogen, and does it cleaner and at costs far lower than any other green hydrogen producer. Rex Parris.

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Ranges in passenger occupancy can easily change the relative performance of modes, with large aircraft performing better than light rail in some of the areas investigated. Samples of the findings include: Off-peak urban diesel buses has the largest energy consumption and GHG emissions per PKT, followed by the three light-duty vehicles.

Obama sets goal of reducing US oil imports by 1/3 by 2025; domestic and Western Hemisphere production, natural gas, biofuels, electric vehicles, fleet purchases

Green Car Congress

Meeting the goal of cutting US oil dependence depends largely on two things, Obama said: finding and producing more oil at home, and reducing dependence on oil with cleaner alternative fuels and greater efficiency. Now, in light of ongoing events in Japan, I want to say another word about nuclear power.
