Argonne-led team develops new low-cost cobalt-based catalyst for PEM electrolysis

Green Car Congress

The lack of supply and high cost of iridium pose a major barrier for widespread adoption of PEM electrolyzers. A PEMWE containing this catalyst at the anode demonstrated a current density of 2000 milliamperes per square centimeter at 2.47 Production of green hydrogen at that cost could reshape the nation’s economy.

EIA: growing octane needs widen price difference between regular and premium in US

Green Car Congress

This price difference, or spread, has been generally increasing since 2000. Many factors on both the supply and demand sides are influencing this trend, according to a new brief prepared by the US Energy Information Administration (EIA). The difference between US average retail prices for premium and regular gasoline reached $0.50/gallon

US EIA Reports Record-setting 7% Overall Decline in US Carbon Dioxide Emissions in 2009; Transport Emissions Down 4.1%, Lowest Percentage Reduction of the End-UseSectors

Green Car Congress

The 2009 results reflect a combination of factors, EIA said, including some particular to the economic downturn; other special circumstances during the year; and other factors that may reflect persistent trends in the economy and in energy use. The average decline in energy intensity from 2000 to 2008 was 2.0%. between 2008 and 2009.

EIA releases report on CO2 emissions by state; California led in 2010 with transportation-sector emissions

Green Car Congress

The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010. For example, some states are located near abundant hydroelectric supplies, while others contain abundant coal resources. From 2000 to 2010, CO 2 emissions fell in 32 states and rose in 18 states.

Audi puts steel back in the new A8

Green Car Congress

Steel’s strength has multiplied by almost 10 times over the past 20 years, from 270 to 2000 MPa tensile strength. Around 17% of the new A8 body structure will comprise press hardenable steel (PHS), some of which will be supplied by ArcelorMittal. Since then, steel has evolved significantly. Click to enlarge.

Shell updates energy scenarios; world entering an era of volatile transitions

Green Car Congress

Improvements in policy-making and strong gains in productivity have helped economies to grow without inflation in the last two decades. Demand pressures will stimulate alternative supply and more efficiency in energy use, but these alone may not be enough to offset growing demand tensions completely. Supply-demand tensions.
