Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

Researchers at the University of Oxford have developed a method to convert CO 2 directly into aviation fuel using a novel, inexpensive iron-based catalyst. Jet fuel can then be obtained from the products after industrially recognized treatments such as distillation or hydro-isomerization.

Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Estimated attribution of fuel savings due to fuel economy improvements to light-duty vehicles since 1975.

Project HyTime demonstrates potential for major CO2 savings from hydrogen dual fuel

Green Car Congress

More than 14 tonnes of CO 2 was saved in a two-year trial involving just 11 urban trucks and vans running on green hydrogen dual fuel. That is one result of the Low Emission Freight and Logistics Trial (LEFT) project to investigate the practical deployment of hydrogen powered vehicles in the UK.

EEA reports sharp decrease in CO2 emissions of new cars in Europe in 2020

Green Car Congress

2020 car registrations by fuel type in Europe. New car emissions were increasing as recently as two years ago, but the sharp drop last year shows that carmakers respond to CO2 standards. This was 14.5 g (12%) lower than in 2019 and represented the first decrease observed since 2016. in 2019 to about 11% of new registrations in 2020.

UNSW Syndey team develops hydrogen-diesel dual fuel system; 90% H2, more than 85% reduction in CO2

Green Car Congress

Engineers from UNSW Sydney (Australia) have successfully converted a diesel engine to run as a dual-fuel hydrogen-diesel engine, reducing CO 2 emissions by more than 85% compared to conventional diesel. In a paper published in the International Journal of Hydrogen Energy, Prof. below the amount produced by the diesel powered engine.

Novel membrane-free Mg-CO2 battery sequesters CO2 and generates electricity

Green Car Congress

The MF Mg-CO 2 battery system has a structure similar to that of hydrogen fuel cells for use in cars, since it only requires a Mg-metal negative electrode, an aqueous electrolyte, and a positive-electrode catalyst. However, unlike the existing fuel cells, they are based on aqueous electrolytes. Credit: UNIST.

SOLETAIR project produces first 200 liters of synthetic fuel from solar power and atmospheric CO2

Green Car Congress

The SOLETAIR project ( earlier post ) has produced its first 200 liters of synthetic fuel from solar energy and the air’s carbon dioxide via Fischer-Tropsch synthesis. Afterwards, carbon dioxide and hydrogen are first converted into reactive synthesis gas at high temperature and then into liquid fuels in a microstructured chemical reactor.
