Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel heterostructured photocatalyst using titanium and copper, two abundant and relatively inexpensive metals, for the conversion of CO 2 into CH 4. Apart from its CO 2 conversion capabilities, the proposed photocatalyst has other benefits.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

Although the researchers demonstrated this method in a small-scale, highly controlled environment with dimensions of just nanometers (billionths of a meter), they have already come up with concepts for scaling up the method and making it practical for real-world applications. C, hot enough to melt aluminum at normal atmospheric pressure.

Researchers show mixotrophic fermentation process improves carbon conversion, boosting yields and reducing CO2

Green Car Congress

One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. This maximization, though, is limited because of the production of CO 2 during the conversion of sugar into acetyl-CoA in traditional fermentation processes. The concept of mixotrophy and its demonstration. (a,b)

EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%. The patented concept is the subject of an open-access paper published in Frontiers in Energy Research. The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof.

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

Green Car Congress

In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. —Rodney Keith, manager for the advanced concepts group working on the Brayton cycle technology. It may not sound super significant, but it was quite a path to get here. Now that we can get across the river, we can get a lot more going.

ICCT study compares leading global driving cycles and provides usable conversion factors for CO2 emissions

Green Car Congress

The result is a set of usable conversion factors for distance-based CO 2 emissions among the different driving cycles. CO 2 savings was evaluated separately for gasoline and diesel concepts. WLTC will be replacing NEDC in a few years.). efficient operation strategies such as stop/start systems.

Audi aims to reduce CO2 emissions by 30% over the vehicle lifecycle by 2025

Green Car Congress

In the long term, Audi is pursuing the vision of CO2-neutral mobility and aims to be climate-neutral throughout the company on balance by 2050. The next step will be the conversion of the car and engine plant in the Hungarian town of Gy?r. Earlier post.).
