Abstract

Biological methods of hydrogen production represent promising renewable sources of energy. The gas mixture formed during fermentation contains the product, hydrogen, quite diluted: 1 to 10 vol.%. Membrane technologies can be utilized for its separation. They are reliable, energy saving, without formation of a by-product. In case that the requirements on purity of hydrogen for energetics are lower, polymeric membranes can be advantageously utilized. A double-stage membrane process was proposed and implemented on a laboratory scale, see the scheme. The first stage is a ultrafiltration membrane module, placed directly in the bioreactor gas space. Its permeability is very high, whereas separation efficiency is moderate. The second stage of the membrane process consists of a membrane module with high separation efficency. To keep the costs and energy consumption of the whole process moderate a polymeric container for hydrogen storage was proposed. Low production rate of biohydrogen allows us to utilize polystyrene foam with distribution system as a container for the gas at moderate pressure. The above-described way of hydrogen production and storage, i.e.fermentation of microorganisms followed by a membrane separation and storage, is promising and economical. It is considered to have large sources with high industrial potential.
