Abstract
The present invention relates to a method for storing gaseous hydrogen, comprising the steps of producing methanoate (formate) through contacting gaseous hydrogen with carbon dioxide in the presence of a hydrogen dependent carbondioxide reductase (HDCR), and thereby storing of said gaseous hydrogen. The HDCR and/or its complex is preferably derived from Acetobacterium woodii.
Claims19
A method for storing gaseous hydrogen, comprising the steps of producing methanoate (formate) through contacting gaseous hydrogen with carbon dioxide in the presence of a hydrogen dependent carbon dioxide reductase (HDCR), and thereby storing of said gaseous hydrogen.
A recombinant bacterial organism comprising a genetic modification, wherein said genetic modification comprises transformation of said microorganism with exogenous bacterial nucleic acid molecules encoding the proteins FdhF1 and/or FdhF2, FdhD, HycB1 and/or HycB2, and HydA2, HycB3, and optionally AcsA of Acetobacterium woodii, or homologs thereof, whereby expression of said proteins increases the efficiency of producing formate from CO2, and/or CO and H2.
(canceled)
15 The method according to claim 3, wherein said complex further comprises a CO dehydrogenase and a ferredoxin, or a homolog thereof.
The method according to claim 15, wherein said CO dehydrogenase is AcsA of Acetobacterium woodii, or a homolog thereof.
