2. 21. Diffusive Combustion of Ethanol in a Dual-Fuel Direct Injection Compression Ignition Engine

   Author : Nicola Giramondi; Anders Christiansen Erlandsson; Mihai Mihaescu; Anders Jäger; Jan Erik Eismark; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Abstract : The impact of climate change due to global warming necessitates rapid and extensive measures to enhance the sustainability of the energy and transport sectors. In this context, there are large environmental and societal benefits to be gained by replacing diesel with renewable fuels for road freight transport. READ MORE

4. 22. Concentrate or dilute contaminants? : Strategies for Swedish wood waste

   Abstract : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. READ MORE

6. 24. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production

   Author : Devy Kartika Ratnasari; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-MCM-41; lignocellulose biomass; H-ZSM-5; kinetic study; catalyst regeneration;

   Abstract : The rapid increase in energy demand, the extensive use of fossil fuels, and the urgent need to reduce carbon dioxide emissions have raised concerns in the transportation sector, since transportation has been primarily dependent on fossil fuels. Biofuel from biomass can make significant contributions to overcome the expected depletion of fossil fuels and reduce carbon emissions. READ MORE

7. 25. Towards More Coherent and Sustainable Biomass Policy: Examining European biomass-to-energy planning

   Author : Niina Kautto; Internationella miljöinstitutet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy; Biomass policy; Renewable energy; Policy coherence; National action plan; Strategic planning; European Union; Region;

   Abstract : Coordination of policies embracing biomass use has been called for in order to speed up progress towards the European Union renewable energy and climate change goals. Policy coordination and coherence is also required if the many complex and diverse issues constraining sustainable bioenergy development are to be addressed. READ MORE
