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. below the amount produced by the diesel powered engine. CO 2 reduction and 13.3% IMEP/efficiency increase are achieved.

Volkswagen LCA highlights carbon benefits of EV vs diesel on Golf: 119 vs 140 g CO2/km; ID. family to reduce footprint

Green Car Congress

In summary, the current Golf TDI (Diesel) emits 140g CO 2 /km on average over its entire life cycle, while the e-Golf reaches 119g CO 2 /km. Here the Diesel reaches 111 g CO 2 /km. According to LCA, a diesel here generates 29 g CO 2 /km, while 57 g CO 2 /km were determined for a comparable e-vehicle. In 2015, the figure was 43.6

GlobalData: COVID-19 puts EV sales and CO2 fleet emission targets at risk

Green Car Congress

This could prove very problematic for the industry in a year that was supposed to mark the big shift to EVs to reduce fleet CO2 emissions in line with new tighter EU CO 2 targets. Much lower pump prices for gasoline and diesel have been ushered in by the COVID-19 crisis and a big hit to global oil demand.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

The researchers carried out their calculations based on a Mercedes-Benz C 220 d diesel and the new Tesla Model 3. They report that even with today’s technology, total emissions from a combustion engine powered by natural gas are already almost one-third lower than those of a diesel engine. Electricity production in Germany, 2018.

JATO: European new car CO2 emissions highest average since 2014; shift from diesel to gasoline and SUVs rise

Green Car Congress

The analysis covered 23 markets in Europe and found a direct correlation between diesel car registrations and average CO2 emissions. With increased negative public perception towards diesels, combined with new government regulations such as WLTP and scrutiny of the fuel type, demand for diesel fell by 18% in 2018.
