Full substitution of diesel with hydrogen may not be convenient for … the time being but employing of hydrogen in a diesel engine in dual fuel mode is possible. In this experimental …

Possibly one of the most significant advantages that hydrogen may have as a fuel is its potential for increased second … hydrocarbon-based fuels. A computational investigation of this effect is pursued for the case of mixtures of hydrogen and natural … function of hydrogen content of the fuel and the operating parameters of the engine.

This paper experimentally investigated the co-effect of cylinder cutoff and hydrogen addition … engine equipped with an electronically controlled hydrogen injection system and a hybrid electronic control unit. The engine …, respectively. For each cylinder closing strategy, the hydrogen energy fraction in the total fuel (βH2) was increased from 0% to …

The membrane reactor is a novel technology for the production of hydrogen from natural gas. It promises economic small …-scale hydrogen production, e.g. at refuelling stations and has the potential of inexpensive CO2 separation. Four configurations of … to assess the trade-off between production scale and the construction of a hydrogen and a CO2 distribution infrastructure …
