On solar energy balance and conservation in the experimental system for continuous hydrogen production

This paper is mainly to introduce a new system for continuous hydrogen production which can help to integrate the concentration and transfer of solar power and the biological hydrogen production. By taking the system as the research object, we have established the energy balance model for the continuous hydrogen production of the solar power. In this experimental system, the total input of energy is equal to 19.12× 10~5 kJ·d~(-1), including the optical energy,thermal energy, electricity and chemical energy, with its energy output being 3.34 ×10~5 kJ · d~(-1), including the energy brought out by hydrogen and other gases. The result of our study shows that the effective utilization rate of energy turns to be less than 17.5%, whose calculation was done based on the black box principle and the total energy conversation with the improvement of conversion efficiency of light energy made. The hydrogen production and energy output have been raised with the effective utilization of the energy system as a result of detailed study of the situation of energy consumption. Through the improvement of the experimental system, it can be" said that we have found a feasible way to improve the effective ufilization of solar energy with technologies such as coupling absorption spectrum of photosynthetic bacteria with solar spectrum, the improvement of the light sources in the internal space of the reactor, plus the specific surface area of reactor, co-cultivating photesynthetie bacteria with algae, as well as the optimization of the concentration of microbes.
