Carbon: Hydrogen carrier or disappearing skeleton?

Theoretical analysis of the effect of catalyst mass distribution and operation parameters on the performance of a Pd-based membrane reactor for water–gas shift reaction

“…Traditional energy systems (power plants or vehicles) are characterized by a low efficiency since over 60% of the input energy is lost; for this reason both new energy sources and more efficient devices would be explored. Hydrogen results an attractive energy carrier for its versatility in different refinery processes and applications as clean fuel [1].…”
