New efficient, low-temperature catalyst for converting water and CO to hydrogen and CO2

Green Car Congress

Scientists in the US and China have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO) via the water-gas shift (WGS) reaction. Its synergy with adjacent Mo sites in α-MoC can effectively activate water at low temperature. —Yao et al.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

The team calculated that an area equal to only 4% of the Sahara Desert would be sufficient to bring atmospheric CO 2 concentrations back to pre-industrial levels in ten years, and that a wind speed of 1 km per hour would be sufficient to deliver that CO2 to those STEP (solar thermal electrochemical process (STEP) CNT plants ( earlier post ).

EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

The system uses the same catalyst for the cathode that reduces CO 2 to CO and for the anode that oxidizes water to oxygen through the oxygen evolution reaction. The system was able to selectively convert CO2 to CO with an efficiency of 13.4% The gases are separated with a bipolar membrane. using solar energy. —Marcel Schreier.

metric tons from 2010 to 2017—equivalent to greenhouse gas emissions from more than 728,000 passenger vehicles driven for one year. In MQL, a machining tool is lubricated with a very small amount of oil sprayed directly on the tip of the tool in a finely atomized mist, instead of with a large quantity of coolant/water mixture.

Elemental boron effective photothermocatalyst for the conversion of CO2 for fuels and chemicals

Green Car Congress

Researchers in Japan and China developed an efficient method for CO 2 reduction over elemental boron catalysts in the presence of only water and light irradiation through a photothermocatalytic process. At this temperature it reacts with water, forming hydrogen and boron oxides in situ. —Jinhua Ye.

Audi Hungaria starts operation of Europe’s biggest solar roof installation

Green Car Congress

The focus lies on the challenges that are key to Audi: decarbonization; water utilization; resource efficiency; and biodiversity. Since 2015 the company has made use of 250 gigawatt-hours of geothermal energy, reducing emissions of CO2 by 50,000 tonnes. Since the start of this year, all Audi plants have used only green power.
