Biomass Energy 12/4/2014 23 Image: http://www.williamsrenewables.co.uk/wp-content/uploads/2013/09/diagram.gif Terrestrial biomes Industrial waste Marine biomass
Second-largest source of renewable electricity generation 12/4/2014 24 Graph: Department of Energy, Energy Information Administration, Energy Outlook 2009. Biomass is the fastest growing, going from 11% of the total in 2007, to more than 41% in 2030.
12/4/2014 25 Miscanthus Switchgrass Hemp Bamboo Maize Sugarcane Oil palm Rice Terrestrial biomes used for energy production Thermal conversion Chemical conversion Biochemical conversion Ethanol – Bioalcohols - Biodiesel - Biofuel gasoline - Bioethers - Biogas
Advantages of terrestrial biomes 12/4/2014 26 Advantages Clean and eco-friendly energy source. Products that are used in biomass are easily available. The material for biomass will surely never run out.
12/4/2014 27 Disadvantages of terrestrial biomes Costly sometimes (depending on the substrate). The clearance of large areas including forests. Releases methane into the air (lesser than fossil fuels). Sustainable under certain conditions only. Consumption of fresh water. Competition for arable land. Food-fuel debate.

12/4/2014 34 Advantages of macroalgae as a biomass for energy production No fresh water required. Very abundant. Plays an important role in carbon capture and CO2 storage (0.7 million tons/year). Nitrogen and phosphorus are provided by fish. Can be collected from industrial waste.
