BIOMASS ENERGY International Renewable Energy Youth Competition Una Pale Omri Danziger Avishai Ketko

biomass renewable energy resource biological material from living, or recently living organisms based mostly on carbon, hydrogen and oxygen

getting the energy from biomass energy in form of: –heat, current, methane, transportation fuel: ethanol, biodisel combustion –burning organic material pyrolysis –thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen gasification

biomass clean and combustible gas (syngas) reacted with controled amount of steam and air at high temperature product gases: CO, H2, CO2, CH4…

equation incomplete combustion of hydrocarbons products: H2, CO, CO2, CH4, H2O and un-burnt carbon

our idea mirrors instead of woods –higher temperature –more gas (fuel) –less pullution –less wood wasted as a feedstock for heating the furnace pictures of our idea

energy transformation energy from the sun solar energy biomass: plants, woods, algaes… chemical energy + air and steam sunlight reflection on mirrors focused on the furnace heat gasification combustible gases: H2, CO … fuel: biodisel, ethanol…

conditions needes –in the furnace: the same –outdoor conditions: sun economic consideration: –cheaper –getting more gas (fuel) future –solar focus technology will improve –enhance the eficiency of the process no environment impact –no releasing CO2 into the atmosphere –heating with the sun – no impact

biomass in dead trees Advantages no need to cut down trees the trees are dried biomass Dissadvantages water is needed the trees could be far away

Thank you for your attention =)
