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.

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 …

This study deals with solar hydrogen production from the two-step iron oxide thermochemical cycle (Fe3O4/FeO). This … exothermic steam hydrolysis of the reduced metal oxide (wustite) for hydrogen generation. Thermodynamic and experimental … investigations have been performed to quantify the performances of this cycle for hydrogen production. High-temperature decomposition …
