Supreme Court curbs EPA authority to regulate CO2 from power plants

Green Car Congress

The Supreme Court of the US (SCOTUS) has ruled in West Virginia v. EPA that the EPA lacks the authority to set emission standards for power plants so strict as to force a shift of power generation from fossil fuels. —Opinion in West Virginia v. forcing a shift from higher-emitting to lower-emitting producers.

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

Green Car Congress

Energy-related CO 2 emissions buy state, 2010. The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010. The report shows a significant variation of energy-related carbon dioxide emissions across states on both an absolute and a per capita basis.

Researchers develop bi-metallic catalyst for thermocatalytic decomposition of methane: H2 with low or no CO2

Green Car Congress

The closed-loop cycle allows for continuous catalyst replacement while emitting zero carbon dioxide emissions. For decades, PNNL scientists and engineers have led research using catalysts to reduce CO 2 emissions from industrial processes and transportation.

First-of-a-Kind Field Test for Enhanced Coalbed Methane Recovery with Simultaneous CO2 Sequestration

Green Car Congress

Injection of CO 2 began in a first-of-a-kind US Department of Energy–sponsored field trial of enhanced coalbed methane recovery with simultaneous CO2 sequestration in an unmineable coal seam. The field test is incorporating numerous site characterization and monitoring activities to ensure the safety and efficacy of CO2 injection.

Chilled Ammonia Pilot Project Captures 90% of CO2

Green Car Congress

Units 1 and 2 at the Pleasant Prairie Power Plant (P4) recently were retrofitted with selective catalytic reduction (SCR) systems to control emissions of nitrous oxides (NO x ) and wet flue gas desulfurization (FGD) systems to control sulfur dioxide (SO 2 ) emissions. This retrofit also included the construction of a new chimney.

Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Green Car Congress

Regionally specific lifecycle CO 2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., Under some conditions, the battery electric Nissan LEAF can produce higher emissions than a Toyota Prius hybrid.
