Bio-methane production from dedicated energy crops has become a part of the overall global bio-energy production industry. Bio-methane (biogas) has the potential to yield more energy than any other current type of biofuel (biodiesel, bioethanol) as a larger proportion of the biomass can be converted to product.

Bio-methane can be produced from a wide range of conventional biomass crops. Closed algal bioreactors offer a promising alternative route for biomass feedstock production for bio-methane. Using these systems, micro-algae can be grown in large amounts (150-300 tons per ha per year) using closed bioreactor systems. This quantity of biomass can theoretically yield much more than those from maize and grass. This chapter deals with the different methods of extraction and production of methane gas from algae biomass.
