of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.

Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Under illumination for 6 hours, the optimized reduced titania-Cu 2 O photocatalyst enables 0.13% photoreduction of highly diluted CO 2 with water vapors to 462 nmol g ?1 What if we drew inspiration from photosynthesis, the process by which plants use sunlight to convert CO2 and water into useful chemicals?

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

Water from the Hellisheiði power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth. The water returns to the cycle of the geothermal power plant. This uses a specially developed adsorbent to bind the CO 2 in the air.

DOE selects 2 projects to demonstrate feasibility of enhanced water recovery; producing usable water from CO2 storage sites

Green Car Congress

The US Department of Energy (DOE) has selected two projects that will test emerging enhanced water recovery (EWR) technologies for their potential to produce useable water from CO 2 storage sites. Once treated, the clean water could be re-used for beneficial purposes, including supplemental cooling water at a power station.

BMW i Ventures invests in Prometheus Fuels; CO2 air-capture and conversion to carbon-neutral gasoline

Green Car Congress

By creating carbon-neutral gasoline from CO 2 captured from the air, Prometheus Fuels allows the climate impact of today’s internal combustion engines to be massively reduced immediately. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2.

Prometheus CEO outlines tech advances that could make CO2-to-fuels renewable gasoline and jet price-competitive with fossil fuels

Green Car Congress

This is an important development because there is little time available to reduce CO 2 emissions sufficiently to avoid the worst effects of climate change. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2. to C 2 fuel products such as ethanol.
