Introduction：

Industrial and developing nations are facing an unprecedented combination of economic, environmental, and political challenges. From the standpoint of international security, energy issues include the potential for conflict over access to remaining supplies of inexpensive fossil fuels often concentrated in politically unstable regions. Consequently, the growing energy needs necessitate much greater reliance on a combination of fossil fuel-free energy sources and on new technologies for capturing and converting CO₂.

Hydrogen offers an alternative as an energy carrier for stationary and mobile power generation. It has a large gravimetric energy density and its oxidation with oxygen in fuel cells produces only water vapor. Unfortunately, 96% of hydrogen is currently produced from fossil fuels. Photobiological hydrogen production by cultivation of photosynthetic microorganisms offers a clean and sustainable alternative to thermochemical or electrolytic production technologies with the added advantage of CO₂ mitigation.

This seminar presents photobiological hydrogen production by Anaebena variabilis and wild and genetically modified Chlamydomonas reinhardtii with reduced pigment concentrations. Design, instrumentation, operation, and performances of an instrumental photobioreactor are described. The effects of genetic engineering on the radiation characteristics of C. reinhardtii are quantified experimentally. Finally, simulations of light transfer through photobioreactors and scale-up challenges are discussed.
