Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle.

Supreme Court curbs EPA authority to regulate CO2 from power plants

Green Car Congress

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. It located that newfound power in the vague language of an “ancillary provision[]” of the Act, Whitman, 531 U.S., The Supreme Court of the US (SCOTUS) has ruled in West Virginia v.

EIA: CO2 emissions from US power sector have declined 28% since 2005

Green Car Congress

US electric power sector CO 2 emissions have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity, according to the US Energy Information Administration (EIA). In 2005, noncarbon sources accounted for 28% of the US electricity mix.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

According to a new study published by the ifo Institue Center for Economic Studies (CESifo) in Germany, EVs will barely help cut CO 2 emissions in the country over the coming years, as the introduction of electric vehicles does not necessarily lead to a reduction in CO 2 emissions from road traffic given the current power generation mix.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. The results are reported in an open-access paper in the journal Communications Biology.

Yamaha and Sumitomo demo on-board thermoelectric generator for CO2 reduction

Green Car Congress

Yamaha Corporation and Sumitomo Corporation Power & Mobility Co., a Sumitomo Corporation Group company, jointly demonstrated a new waste heat recovery system based on a thermoelectric generator (TEG), which generates electrical power via exhaust gas heat. An additional test achieved the target gas temperature.
