Abstract
Biomass is a energy from the solar which has a very high potential to replace the fossil fuel. It is also potential contributor to low greenhouse gas emissions. Since the humans contribute to one quarter and in fact is left to decay naturally. Biomass energy conversion uses the raw material from agricultural and forest product residues. The biomass collected can be combusted, gasified, biologically digested or fermented depending on the product and the desired carrier product. Research opportunities include improvements in the photosynthetic efficiency and nutrient requirements of energy crops, biomass-tailored thermochemical conversion systems, and genetic engineering of microorganisms for more efficient biological conversion and the efficient production of hydrogen directly from sunlight.
