  2. 11. CFD Modeling of an Alcohol-Diesel Direct-Injection Dual-Liquid-Fuel Engine using OpenFOAM

    Author : Andreas Nygren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Fuels; Dual-Fuel Combustion; CFD; Spray Modeling;

    Abstract : Legislation for heavy duty combustion engines are becoming more stringent. To keep up with the legislation, new engine technology is required. Furthermore, renewable fuels can also be used together with new engine technology to further reduce emissions. READ MORE

  4. 12. Micro-grids supplied by renewable energy : Improving technical and social feasibility

    Author : Caroline Bastholm; Ewa Wäckelgård; Annette Henning; Frank Fiedler; Kirsten Ulsrud; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; Electricity access; Decentralized; Off-grid; Photovoltacs; PV-hybrid; Micro-grid; Multi-disciplinary; Sociotechnical; Engineering Science; Teknisk fysik; Energy and Built Environments;

    Abstract : Universal access to electricity stands high on the global agenda and is regarded as essential for positive development in sectors such as health care, education, poverty reduction, food production and climate change. Decentralized, off-grid electrification is deemed an important complement to centralized grid extension. READ MORE

  5. 13. Reducing greenhouse gas emissions – Examples from the freight transport sector: Essays on economic growth, public policy instruments, and renewable energy

    Author : Johanna Takman; Johan Woxenius; Statens väg- och transportforskningsinstitut; []
