Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The facility will filter 4,000 metric tons of carbon dioxide from the air and mineralize it underground. With direct air capture technology, carbon dioxide is extracted from the ambient air and air free of CO 2 is returned to the atmosphere. The carbon dioxide is thus permanently removed from the atmosphere.

BMW Group secures CO2-reduced steel for global production network

Green Car Congress

This will reduce the carbon footprint of our supply chain by 900,000 tonnes per year, while at the same time driving the transformation of the steel industry. With its versatile properties, steel is nevertheless one of the key materials for automotive manufacturing and will be no less important for future vehicle concepts and generations.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle. Supercritical carbon dioxide is a non-toxic, stable material that is under so much pressure it acts like both a liquid and a gas. Now that we can get across the river, we can get a lot more going.

DHL, Shell and Grundfos Bio-LNG pilot for road freight delivers 85% CO2 savings over conventional diesel

Green Car Congress

This corresponds to the emissions of more than 89,900 km driven by a diesel truck and represents 85% of CO2 savings compared to a traditional diesel engine. The logistics industry is currently responsible for 11 percent of global carbon emissions. The Bio-LNG used by Shell in the test is produced from agricultural waste.

New Mercedes-Benz S-Class PHEV produces 14.1-36.2% lower CO2 emissions that predecessor

Green Car Congress

The upstream production of materials and components creates more carbon dioxide than for the previous model. Alongside the CO2 improvement, the S 580 e also has advantages over its predecessor with respect to its eutrophication (EP) and summer smog (POCP) potential. This feeds self-generated green electricity to the production shop.
