  4. 23. Insights from modeling renewable electricity systems and developing hydropower models

    Författare :Hanna Ek Fälth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewables; electricity systems; hydropower; nuclear; modeling; Europe; MENA; transmission; available land;

    Sammanfattning : One strategy for reaching a carbon-neutral electricity system is a large-scale deployment of wind and solar power. However, electricity systems with high shares of wind and solar power rely on other technologies, e.g. LÄS MER

  5. 24. Gold, Coal and Iron : Essays on Industrialization and Economic Development

    Författare :Adrian Poignant; Niklas Bengtsson; Mounir Karadja; Ola Olsson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity; female employment; labor supply; artisanal mining; agriculture; displacement; industrialization; industrial revolution; Economics; Nationalekonomi;

    Sammanfattning : Essay I: How does electricity provision affect female employment? In theory, electrical household appliances can save labor in domestic production and divert it to the market. However, the empirical evidence has been inconclusive. LÄS MER

  7. 25. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society

    Författare :Håkan Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; Black liquor gasification; Biomass; Combined Cycle; Eco cyclic pulp mill; CHP; Electricity production; Recovery boiler; Gas turbine;

    Sammanfattning : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. LÄS MER
