Innovative water treatment at Audi Ingolstadt saves up to 500,000 cubic meters of fresh water a year; heading to ZLD

Green Car Congress

Audi has put a new service-water supply center into operation at the Ingolstadt site. In this way, Audi will saves up to 500,000 cubic meters of fresh water each year. The heart of the service-water supply center is a membrane bioreactor (MBR). The heart of the service-water supply center is a membrane bioreactor (MBR).

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

Green Car Congress

In the new study, we have analyzed 20 years of aviation emissions, up until and including 2018. Net positive RF (warming) contributions arise from CO 2 , water vapor, NO x , and soot emissions, and from contrail cirrus (consisting of linear contrails and the cirrus cloudiness arising from them). For 2018 the net aviation ERF is +100.9

Evonik and Siemens launch phase 2 of Rheticus: butanol, hexanol from CO2 and water using renewable electricity and bacteria

Green Car Congress

The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals. From the Supplementary Information for a 2018 paper in Nature Catalysis by the Evonik-Siemens team (Haas et al. describing the approach.

Researchers find bio-inspired high-tech surfaces on hulls could greatly reduce drag and CO2 emissions of ships; up to 1% of global CO2

Green Car Congress

The main reason for this is the high degree of drag between hull and water, which constantly slows the ship down. The water velocity at the surface boundary layer is zero. (b) b) An air layer functions as slip agent, the water velocity at the interface is larger than zero, drag is reduced. Busch et al. Resources. Barthlott, M.

Researchers develop efficient single-atom Ni catalyst for conversion of CO2 to CO

Green Car Congress

While Ni metal catalyzes the hydrogen evolution reaction (HER) exclusively under CO 2 RR conditions, Ni single atomic sites present a high CO selectivity of 95% under an overpotential of 550 mV in water, and an excellent stability over 20 hours’ continuous electrolysis. The current density can be scaled up to more than 50 mA cm?2

Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

They applied a comprehensive suite of experimental and theoretical methods to identify the structure of the first intermediate of CO 2 electroreduction: carboxylate CO2 - that is attached to the surface with C and O atoms. Their paper is published in Proceedings of the National Academy of Sciences (PNAS). 1802256115.

New catalyst opens door to CO2 capture in coal-to-liquids process

Green Car Congress

Some of the CO is taken out of the syngas (rejected) by converting it to CO 2 , in a process called the water-gas shift. The CO 2 that was previously released in this stage can now be removed in the preceding water-gas shift stage. Hensen (2018) “Synthesis of stable and low-CO 2 selective ?-iron
