1. 1. Towards Sustainable Shipping: Climate change and other environmental perspectives on carbon-based marine electrofuels and onboard carbon capture

   Författare :Elin Malmgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; liquefied natural gas; power-to-X; methanol; power-to-gas; carbon capture and utilization; thematic analysis; Marine renewable energy; onboard carbon capture; marine fuels; LCA; shipping; electrofuels;

   Sammanfattning : The global, local, and regional environment is under pressure from human activity. Shipping is a human activity causing emissions to air, water, and soil, which has direct and indirect effects on the environment. LÄS MER

3. 2. The role of methane and hydrogen in a fossil-free Swedish transport sector

   Författare :Mårten Larsson; Per Alvfors; Stefan Grönkvist; Max Åhman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable transport fuels; biogas; methane; hydrogen; electrofuels; pyrolysis; well to wheel; transport policy; energy policy; Chemical Engineering; Kemiteknik;

   Sammanfattning : Drastic reductions of greenhouse gas emissions are required to limit the severe risks associated with a changing climate. One measure is to disrupt the fossil-fuel dependency in the transport sector, but it appears difficult and costly in comparison to other measures. LÄS MER

4. 3. Towards sustainable shipping: Evaluating the environmental impact of electrofuels

   Författare :Elin Malmgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental assessment; LCA; emerging technology; marine fuels; human health; future fuel; sustainable shipping; carbon utilization; power-to-x; carbon capture;

   Sammanfattning : The global, local, and regional environment is under pressure from human activity. Changes in the environment can be beneficial and strived for, but environmental and health problems need to be considered when we design human activities. LÄS MER

5. 4. Numerical studies of flame stabilization relevant to gas turbine engines using methane and e-fuels

   Författare :Yazhou Shen; Christophe Duwig; Benoit Fiorina; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : The current society undergoes a global energy transformation from fossil fuels to renewable energy. The alternative energy sources to fossil fuels are key factors to accelerate the transition towards a sustainable energy system. Among those, electrofuels (e-fuels) is a promising group that remarkably benefits overall carbon neutrality. LÄS MER

7. 5. The impact of an Electrification of Road Transportation on the Electricity system in Scandinavia

   Författare :Maria Taljegård; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric road systems; energy consumption; peak power; electric car; variation management; energy system modelling;

   Sammanfattning : The transport sector needs to reduce CO2 emissions by replacing fossil fuels with low-carbon options. An electrification of the road transport sector through electric vehicles (EVs) with static charging; electric road systems (ERS); and using electricity to produce a fuel, are all suggested as possible options.
