Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

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. This new study is based on a thorough review of a decade of research on aviation emissions. Aviation accounts for 3.5% —Marianne Tronstad Lund, co-author.

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? —Prof In.

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.

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.

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.

The Allam-Fetvedt Cycle is a new type of power cycle that takes a novel approach to emissions reduction. It uses the oxy-combustion of carbon fuels and a high-pressure supercritical CO 2 working fluid in a highly recuperated cycle that captures all emissions by design. Clean Power: transformative zero-emissions power cycles.
