    Sammanfattning : Hållbara transporter är en viktig faktor för att minska koldioxidutsläppen och bidra till en mer hållbar framtid. Den svenska järnvägen är en viktig del av infrastrukturen och transporterar dagligen hundratusentals människor och stora mängder varor. Transportsektorn förbrukar nu cirka en tredjedel av den totala energin i världen. LÄS MER

  3. 2. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Ebba Söderström; Emanuel Bengtsson; [2022]
    Nyckelord :Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

    Sammanfattning : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

  4. 3. A Comparative Study to Examine the Feasibility and Climate Benefits of Transporting Mycronic´s Products Using More Sustainable Transport Solutions

    Master-uppsats, KTH/Industriell produktion

    Författare :Amey Shah; [2022]
    Nyckelord :Paris agreement; GHG; CO2 emissions; sustainable; freight transportation; future trends; Parisavtalet; växthusgaser; koldioxidutsläpp; hållbara; godstransporter; framtida trender;

    Sammanfattning : As per the Paris agreement in 2015, 190 nations have joined the cause to cut the Greenhouse gas (GHG) emissions. To limit global warming, the aim is to reduce the global emissions to half by 2030 compared to 2012 and reach net zero by 2050. The transportation industry can play a big role to achieve this target.

  5. 4. Koldioxidavskiljning på ett biobränsleeldat kraftvärmeverk : Simulering av två avskiljningstekniker vid Karlstad Energis kraftvärmeverk, Heden 3

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Sandra Bergström; [2020]
    Nyckelord :Carbon dioxide capture; BECCS; CHP; bio-CCS; HPC; hot potassium carbonate; MEA; mono ethanol amine; carbon capture technologies; carbon dioxide; chemical absorption; carbon dioxide capture and storage; Koldioxidavskiljning; BECCS; kraftvärme; bio-CCS; HPC; kaliumkarbonat; MEA; mono etanol amin; avskiljningstekniker; koldioxid; kemisk absorption; koldioxidinfångning och lagring;

    Sammanfattning : BECCS (Bioenergy Carbon Capture and Storage) is an important part of measures to achieve zero net emissions globally by 2050, as the technology can create carbon sinks. However, the technology is very energy-intensive and expensive, and affects the existing systems at implementation. LÄS MER

  7. 5. The Application of Futures Studies in Innovation Processes : Scenario methods as a tool to facilitate flexibility and enable future resilient products

    Master-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Linda Eriksson; Lina Simme; [2020]
    Nyckelord :futures studies; foresight; scenarios; innovation; innovation process; NPD; new product development;

    Sammanfattning : Companies are pressured by dynamic markets and the increase of innovation speed, technology change and shortening of product life cycles. They need to attend to customer demands and ever-changing environmental conditions, policies and regulations set by governments and institutions in order to stay relevant on the market and be allowed to operate.
