1. Life Cycle Assessment of Present and Future Marine Fuels
Sammanfattning : 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.

2. Generation of synthesis gas for fuels and chemicals production
Sammanfattning : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. LÄS MER
3. Power to gas : Bridging renewable electricity to the transport sector
Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER
4. Methanation of biosyngas in a fluidized bed reactor
Sammanfattning : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. LÄS MER
5. An Experimental Study of Fischer-Tropsch Fuels in a Diesel Engine
Sammanfattning : Alternative fuels for Diesel engines include ester-based fuels (derived from sources such as rapeseed, soybeans and palm oil), dimethyl ether, and various synthetic fuels. Use of these fuels could contribute to a cleaner environment, reduce global warming and improve the human health by reducing levels of harmful emissions. LÄS MER
