Partners of the P2X Kopernikus project on the premises of Karlsruhe Institute of Technology (KIT) in Germany have demonstrated the production of fuel from air-captured CO2 using—for the first time—a container-based test facility integrating all four chemical process steps needed to implement a continuous process.
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.
The US Environmental Protection Agency (EPA) has released the 17 th annual US greenhouse gas (GHG) inventory. As the largest source of US greenhouse gas emissions, CO 2 from fossil fuel combustion has accounted for. When electricity-related emissions are distributed to economic end-use sectors, transportation activities accounted.
In 2010, the price of regular gasoline averaged $2.78 This contributed to a decline in gasoline consumption of 2.9% This would tend to put upward pressure on electricity demand and related emissions. A carbon intensity decline in the electric power sector (-4.0%) which accounted for 40% of total U.S. per gallon.
Stay-at-home orders, travel restrictions, and work-from-home arrangements reduced demand for motor gasoline, distillate fuel oil (primarily consumed as diesel), and jet fuel. Natural gas accounts for the second-largest share of energy-related US CO 2 emissions, at 33% of the 2019 total.
Net emissions resulting from the use of plug-in hybrid electric vehicles (PHEVs) depend on the efficiency of the conventional vehicle fleet; PHEV CD (all-electric, charge-depleting mode) efficiency; charging strategy; battery pack capacity; driving patterns; and generator mix used for charging. —Peterson et al.

The process developed by SunFire begins with the decomposition of water into hydrogen and oxygen by using electrolysis, driven by renewable electrical energy (derived from sunlight, wind or water). A subsequent step is the reaction of hydrogen and the CO 2 to form renewable, synthetic gasoline, diesel and kerosene. Approximately 2.6

Even if all cars were to drive electrically one day, aircraft, ships, and even trucks will still run mainly on fuel. In this way, the cost of exhaust-gas treatment can be reduced, Bosch adds. If the electricity used is generated from renewables (and thus CO 2 -free), such fuels are carbon-neutral and very versatile.
In the United States, emissions associated with the consumption of petroleum fuels—motor gasoline, distillate, jet fuel, and more—have consistently made up the largest portion of CO 2 emissions. Natural gas surpassed coal to become the most prevalent fuel used to generate electricity in the United States in 2016.
The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. The EIA projects that fuel switching in the electric power sector and declines in industrial use will lead to a 7.9% Natural Gas.
tonnes more CO 2 than an equivalent gasoline car over its lifetime due to a more energy-intensive refining of the diesel fuel; more materials required in the production of heavier and more complex engines; higher emissions from biodiesel blended in the diesel fuel; and longer mileage because fuel is cheaper. l/100 km (37.3 mpg US) and 7.1
The Lenfest/Risø team notes that high temperature electrolysis makes very efficient use of electricity and heat (near-100% electricity-to-syngas efficiency), provides high reaction rates (no need for precious metal catalysts), and the syngas produced can be catalytically converted to hydrocarbons in well-known fuel synthesis reactors (e.g.

Motor gasoline accounted for 56.0%
EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies. Click to enlarge.
SEAT, a member of the Volkswagen Group, continues to spearhead the introduction of compressed natural gas (CNG) technology, giving customers the widest choice of vehicles that are cleaner, more sustainable and offer even greater efficiency. A CNG vehicle reduces CO 2 emissions by about 25% compared to a gasoline-driven equivalent.
The report concluded that benefits in the medium- and long-term can be anticipated since the obtaining of an alternative fuel using a residual greenhouse gas would allow European dependence on conventional fossil fuels to be cut, and that way the risks in supply security to be minimized.
A computational analysis that screened hundreds of thousands of zeolite and zeolitic imidazolate framework structures has identified many different structures that have the potential to reduce the parasitic energy loss of carbon capture technologies for powerplant flue gas by as much as 30–40% compared with amine scrubbing. —Lin et al.
Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation. Transportation-related CO2 emissions increased by 38 million metric tons (MMmt) (2.1%) in 2015. Electricity.
While a small share of the thermal energy available is already used today (for example when warming up the engine or through exhaust gas turbocharging), further, specific improvements will serve to reduce fuel consumption and, accordingly, CO 2 emissions once again by several percentage points.
