  1. Research on utilization for Biomass Source Hachinohe National College of Technology（HNCT) Department of Civil and Environment engineering Hasegawa Yuri

  2. Content • Background and Purpose • Research content ・woody resources ・BTL ・potential quantity of woody biomass ・proposal of utilization in Hachinohe • Conclusion

  3. UtilizeUnused Forest Resources

  4. now Woody biomass… occurred on the seashore etc. incineration and industrial waste treatment ・Prepare the Biomass plantation obtain resource quantitatively ・Liquefied fuel generation technology be changed into electric power and heat We should use effectively plan

  5. Keywords ・Carbon-neutral ・Woody biomass ・The electricity generation by biomass

  6. Investigation andexaminationcontent • Estimation of potential amount of woody biomass resources in Aomori Prefecture • The feature of woody biomass power generation, and presumption of potential quantity • The feature of Biomass-to-Liquid technics (BTL), and presumption of potential quantity • Proposal what use in Hachinohe-city

  7. Woody biomass power generation Energy potential quantity of trees or grass = (Weight of a driftwood, pruning branch and Grass cutting generate) × Net calorific value × (1－Moisture content) Net calorific value: Driftwood and pruning branch 10,390MJ/t Grass cutting 13,950MJ/t Moisture content: Driftwood and pruning branch 36.2％ Grass cutting 15.8％ 1MJ=0.278kWh

  8. CO2 Emissions CO2Emissions (kg-CO2) =Amount of power used (kWh) ×Emission factor (kg-CO2/kWh) The Emission factor: 0.473 kg-CO2/kWh

  9. Aomori Prefecture Aomori office Takase river Aseishi dam

  10. Woody biomass recovery quantityand CO2 emissions The investigation of recovery quantity: 2000-2004 year (track record for five years)

  11. The manufacturing process of BTL

  12. Aged deterioration of woody resources(2004-2010)

  13. Aged deterioration of resources (1,000m3)

  14. Presumption of the potential quantity of a crude oil equivalent (BTL) (10,000kL)

  15. The utilization proposal of woody biomass (Hachinohe-Port)

  16. Conclusion • It is important for Japan to use woody biomass as energy resources. • Aomori is blessed with nature and holds many forests. Exploitation of woody biomass resources is maintainable energy resources. • We should coexist with nature, which is important to utilization of them.

  17. Thank you.
