2. 1. Cost and financing of the sustainability transition of the Swedish road freight transport sector

   Author : Elmira Parviziomran; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

   Abstract : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.

4. 2. The open absorption system : energy savings in different applications

   Author : Lars Johansson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands.

5. 3. Numerical optimization of hull/propeller/rudder configurations

   Author : Kaijia Han; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel cost savings; optimization; pressure fluctuation; self-propulsion; RANS; verification and validation; cavitation; open water; lifting surface; hull-propeller-rudder; effective wake; efficiency; aspect ratio; lifting line; interaction;

   Abstract : The new framework of the global economy has stimulated and expanded the shipbuilding and shipping industry, especially in Asia in the twenty-first century. This induces urgent and high requirements on designing and building both conventional and new types of ships with high performance, such as high speed, manoeuvrability, seaworthiness and so on.

6. 4. District heat production under different environmental and social cost scenarios

   Author : Nguyen Le Truong; Leif Gustavsson; André Faaij; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heat production; primary energy use; minimum-cost system; co-production;

   Abstract : District heat production systems (DHSs) are normally designed to meet the heat demand of customers at a minimum cost whilst fulfilling local and national regulations. Various factors influence the choice of district heat production units in a minimum-cost system. READ MORE

7. 5. Wood Fuel Pellets: Sawdust Drying in the Energy System

   Author : Magnus Ståhl; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; VOC; system integration; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : In 2004, the amount of wood fuel pellets used in Sweden was 1 256 000 tons, it was mostly used in large scale burning for district heating. Over the last 10 years, a significant increase in pellet production has occurred and today the preferred raw materials for pellet production, i.e., dry sawdust and wood shavings, are insufficient.
