BIOMASS ENERGYInternational 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
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 from the sun solar energy biomass: plants, woods, algaes… chemical energy + air and steam sunlight reflection on mirrors focused on the furnace heat energy transformation 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
Advantages no need to cut down trees the trees are dried biomass Dissadvantages water is needed the trees could be far away biomass in dead trees
