2. 1. The Character of the Particle Emissions from Possible Future Marine Fuels in SOx ECAs

   Author : Maria Anderson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy fuel oil; emission factor; marine fuel; black carbon; marine diesel oil; LNG; ship emission; liquefied natural gas; nanoparticle;

   Abstract : Particles in the ambient air come from both natural and anthropogenic sources. One anthropogenic source is combustion of fossil fuels. The awareness of these particles impact on human health and climate has increased the interest for the particle emissions from e.g. READ MORE

4. 2. Environmental assessment of present and future marine fuels

   Author : Selma Brynolf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Our globalised world is connected by shipping, an industry powered by one of heaviest and dirtiest products of refining: heavy fuel oil. Tougher environmental regulations are now challenging the industry to take action. READ MORE

5. 3. Life Cycle Assessment of Present and Future Marine Fuels

   Author : Selma Bengtsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

   Abstract : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.

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

   Author : Elin Malmgren; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Advancing the understanding of pilot ignition in dual fuel engines : Experimental and conceptual studies

   Author : Menno Merts; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion engines; Dual fuel; RCCI; Pilot injection; renewable fuels; Conceptual model; LTC; Heavy duty; Marine; Start of combustion; Optical engine research;

   Abstract : The energy transition is looking for new technologies to reduce CO2 emissions. One of the promising options is the dual fuel engine. In this concept, based on a diesel engine, a small pilot diesel injection is used to ignite a second fuel. READ MORE
