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.

IEA: global CO2 emissions rebounded to their highest level in history in 2021; largely driven by China

Green Car Congress

The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions—notably the spikes in natural gas prices—which led to more coal being burned despite renewable power generation registering its largest growth to date. CO 2 emissions from natural gas rebounded well above their 2019 levels to 7.5

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.

EIA: US energy-related CO2 fell by 2.8% in 2019, slightly below 2017 levels

Green Car Congress

In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. Nearly all of the change in CO 2 emissions in 2019 arose in the electric power sector.

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). If electricity demand had continued to increase at the average rate from 1996 to 2005 (1.9%

Engineered E. coli could make carbohydrates, renewable fuel, from CO2

Green Car Congress

Researchers from Newcastle University in the UK have engineered Escherichia coli bacteria to capture carbon dioxide using hydrogen gas to convert it into formic acid. The bacteria grew under gas pressure and generated formic acid from the CO 2 , said Dr. Sargent. —principal investigator Frank Sargent. Resources.
