New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

NO conversion versus ramp-up and ramp-down temperatures for MnCe-7:1 (?), Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. SmMn 2 O 5 (?), GdSrCeMn 7 O 14.83 (?), and Pt (?). Click to enlarge.

The Case for Nuclear Cargo Ships

Cars That Think

Nearly all of the world’s ship fleet still runs on diesel fuel, with about a quarter of new ships on order being built to run on somewhat lower-carbon alternatives like liquefied natural gas, methanol, or hybrid propulsion. Ammonia, meanwhile, has half the energy density of diesel fuel, so ships would need twice as much of it.

Researchers propose CO2 recycling to improve Fischer-Tropsch GTL efficiency and reduce total CO2 emissions

Green Car Congress

Researchers in South Korea are suggesting two new carbon-dioxide-utilized Gas-to-Liquids processes (CUGP) to increase the overall efficiency of conventional Fischer-Tropsch GTL. T synthesis catalysts are beneficial for CO 2 conversion. Overview of the CUGP processes. Credit: ACS, Zhang et al. Click to enlarge.

S. Korean researchers develop new catalytic pathway for direct conversion of CO2 to liquid hydrocarbon fuels

Green Car Congress

A team led by Professor Jae Sung Lee at Ulsan National Institute of Science and Technology (UNIST), with colleagues at Pohang University of Science and Technology (POSTECH), have developed a new pathway for the direct conversion of CO 2 to liquid transportation fuels by reaction with renewable hydrogen produced by solar water splitting.

In addition, it is subject to similar refining, storage and distribution costs currently associated with petrol and diesel, including upstream CO2 emissions where the electricity required is usually generated from fossil fuels. The Conversation [link] accessed 4/6/2020.

JATO: 2018 record year for EVs; sales up 74% to 1.26M units; overall market stable, as SUVs rule

Green Car Congress

The diesel crisis in Europe also helped to raise awareness among consumers about the benefits of driving electric. Elsewhere, Russia climbed the rankings and overtook South Korea, while Argentina and Turkey—two big producers of vehicles—saw declines, having felt the effects of challenging economic times.
