The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand. The researchers also considered intermediate (20% electric-powered miles) electrification—halfway between the high and low.

On average, a 25% reduction in carbon dioxide equivalent (CO2-eq) emissions can be expected on a well-to-wheel (WTW) basis when replacing gasoline by light-duty vehicles (LDVs) running on compressed natural gas (CNG). In this context, it appears that NGVs may compare favorably in many—but perhaps not all—national contexts.

Especially a super luxury car that switches to gasoline with the flick of a finger. The gasoline-only production version of this car, the 7 Series, is available today for between $75,800 and $122,600. Despite an advertising budget that rivals available models, the Hydrogen 7 is not for sale.

A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. A TWP >1 means that the cumulative radiative forcing from choosing natural gas today is higher than a current fuel option after t yr. Click to enlarge.

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.

Stoichiometric gasoline direct-injection technology: injects fuel at high pressure directly into the combustion chamber to improve cooling of the air/fuel charge within the cylinder, which allows for higher compression ratios and increased thermodynamic efficiency. This reduces pumping losses at lighter loads in comparison to a larger engine.
