چکیده انگلیسی
Fixing carbon dioxide (CO2) with solar hydrogen (H2) is a novel alternative to conventional photosynthesis of plants and microalgae. The energy efficiency of CO2 fixation by a hydrogen-oxidizing bacterium was investigated in a closed reactor system. The molar ratio of consumed H2 and CO2 was measured under mass transfer limitation in atmospheres of sufficient H2, low CO2, and a broad range of O2. The energy efficiency, ranging from 10% to 60%, was primarily affected by the oxygen concentration (6-30Â mol%). The research revealed a clear trend that a low oxygen concentration gave high energy efficiency, but slow gas consumption. A high energy efficiency of 50% was measured under a moderate oxygen concentration (10Â mol%). Based on 10% solar hydrogen efficiency, a 5% overall efficiency from solar energy to biomass can therefore be achieved.
