Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

An opposed piston engine with hydrogen combustion could well provide the best-known thermal efficiency from a reciprocating engine, with the potential to match the in-vehicle efficiency of a hydrogen fuel cell. with an air/fuel equivalence ratio (lambda) ? ? Fuel Injection. The only criteria emission of concern is NO x.

Study finds behavior-influencing policies remain critical for mass market success of low-carbon vehicles

Green Car Congress

Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuel alternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study.

Scania approves use of HVO in Euro 6 range

Green Car Congress

Scania has given the green light to hydrotreated vegetable oil (HVO) being used to power its Euro 6 range, provided the fuel used meets technical specification TS15940. Vehicles using HVO—which chemically mimics fossil-fuel-based diesel—can under optimal condition achieve up to a 90% reduction in CO 2 emissions.

Volvo Trucks in Bio-DME Field Test

Green Car Congress

In a joint project with the EU, the Swedish Energy Agency, fuel companies and the transport industry, Volvo Trucks is investigating the potential for large-scale investment in dimethyl ether (DME) fuel produced from biomass (Bio-DME). All this makes Bio-DME an ideal fuel for diesel engines, according to Volvo. Earlier post.).

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

In both electric- and hydrogen-favoring cases, availability of low-carbon electricity and hydrogen prolonged the use of petroleum-fueled ICE vehicles. For example, the study found that the availability of carbon capture and storage (CCS) technology has a major impact on the lowest cost passenger vehicle fuel and technology choice.
