L'équipe a créé un cocktail d'enzymes qui peut extraire de l'Hydrogène à partir d'un des sucres présent dans les plantes (de la Xylose qui est contenue en quantité dans les parois des cellules végétales).
Le plus connu, la cellulose est (C6H10O5)n ... la diférrence est minime avec la xylose: C5H10O5
Je cite: "The key to this exciting development is that Zhang is using the second most prevalent sugar in plants to produce this hydrogen," he said. "This amounts to a significant additional benefit to hydrogen production and it reduces the overall cost of producing hydrogen from biomass." Mielenz said Zhang's process could find its way to the marketplace as quickly as three years if the technology is available. Zhang said when it does become commercially available, it has the possibility of making an enormous impact.
Et: The team liberates the high-purity hydrogen under mild reaction conditions at 122 degree Fahrenheit and normal atmospheric pressure. The biocatalysts used to release the hydrogen are a group of enzymes artificially isolated from different microorganisms that thrive at extreme temperatures, some of which could grow at around the boiling point of water.

Avec la bonne vieille formule ( 2 x H ... si "on" arrive à mettre ce côté le côté un peu explosif de l'2 + O2 ) = 2 x HO2H, cela ferait un carburant assez écologique.2
