  1. 1. On maintenance optimization for offshore wind farms

    Författare :Francois Besnard; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle cost; optimization; maintenance; maintenance planning; Offshore wind energy; maintenance strategy; maintenance support organization; reliability;

    Sammanfattning : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

    Sammanfattning : Rural electrification in developing countries has become one of the greatest challenges for achieving global access to electricity—one of the United Nation’s sustainable development goals. Governments, international entities and private companies are tasked with improving the quality of life for people and reducing environmentally harmful emissions. LÄS MER

  4. 3. Combined Energy Systems Applied to Productive Sectors: The Case of Dairy Farms in Central Bolivia

    Författare :Johnny Villarroel-Schneider; Anders Malmquist; Andrew R. Martin; Monica Odlare; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bolivia; polygeneration; trigeneration; productive sector; dairy; biogas; electricity; refrigeration; multiservice; performance; techno-economic; Bolivia; poligeneración; trigeneración; sector productivo; lechería; biogás; electricidad; refrigeración; multiservicio; eficiencia; tecno-económico; Energiteknik; Energy Technology;

    Sammanfattning : Most energy solutions in developing countries focus primarily on solving domestic energy demands of their growing populations without due consideration of sustainable development. On the other hand, in most of these countries, a segment of energy users that has not received enough attention from governments and institutions regarding appropriate energy solutions is the productive sector.

    Författare :Babak Khavari; Francesco Fuso Nerini; William Usher; Mark Howells; Erik Ahlgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : In 2015 the United Nations (UN) General Assembly agreed on the Sustainable Development Goals (SDGs), a set of 17 goals defined by 169 targets to be reached by 2030. Amongst them is SDG 7. SDG 7 states “Ensure access to affordable, reliable, sustainable and modern energy for all”. LÄS MER

  7. 5. Integrating Biomass in Existing Natural Gas-Fired Power Plants

    Författare :Erik Pihl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

    Sammanfattning : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.
