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.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.

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.

Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2

Green Car Congress

Water and oxygen are the only by-products. Driving with Audi e-gas is climate-neutral, since the CO 2 generated when the vehicle is driven had been bound previously during the production of the e-gas. At this facility, microorganisms use water (brackish, salt or wastewater) sunlight and carbon dioxide to produce high-purity fuels.

US and China jointly announce GHG reduction targets; US to cut net GHG 26-28% by 2025, China to peak CO2 by ~2030

Green Car Congress

The Administration said the United States will submit its 2025 target to the Framework Convention on Climate Change as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015. launching a new track on the interaction of energy and water (the energy/water ‘nexus’).
