The energy supply in the world needs to change from fossil fuels to renewable alternatives. Biogas is such a renewable alternative, and there is potential to increase the biogas production in the world. In recent decades, many countries have increasingly been upgrading biogas to vehicle fuel. In the last few years, the interest has also increased in liquefying biogas for heavier transports. Biogas can also be a raw material for other fuels by gasifying the biogas, for example Fischer-Tropsch fuels, methanol, dimethyl ether and hydrogen. This study provides an overview of vehicle fuels that can be produced from biogas, their technological maturity and their respective potentials as substitutes for fossil fuels in the transport system. A common factor for all of them is that they are most often produced from fossil fuels. Compressed and liquefied methane are the only fuels being commercially produced using biogas. The other fuels all have strengths that both compressed and liquefied methane lack, for example the possibility of emission-free fuel cell vehicles. However, they are all less mature technologies than compressed and liquefied methane. The greatest short-term potential is thus for expanded use of biogas as compressed and liquefied biomethane.

The selection of the suitable propulsion system for LNG carrier highly affects the ship capital and life cycle costs. The current paper compares between the available propulsion systems for LNG carriers from environmental and economic points of view operated with heavy fuel oil (HFO) and marine gas oil (MGO). In addition, the cost-effectiveness for emission reduction due to using dual fuel propulsion options using natural gas fuel (NG) is calculated. As a case study, large conventional LNG carrier class has been investigated. The results show that steam turbine (ST), Ultra-ST, dual fuel diesel engine (DFDE), and combined gas and steam (COGAS) propulsion options can comply with NOx and SOx emissions regulations set by IMO using dual fuel mode with NG percentages of 87.5%, 82%, 98.5% and 94%, respectively. DFDE operated with pilot HFO and NG is the most economic propulsion option.

“…LNG cold utilization is the combination of LNG regasification process with the additional thermal/power cycles . It is the well‐known and commercially preferred method for the large‐scale energy conversion systems, which need the LNG regasification, and the LNG cold‐utilized power generation is the most preferred method of the LNG cold utilization concept among the others . Nevertheless, the small‐scale LNG cold utilization systems have been recently gaining importance by means of the developed technologies that make the small‐scale applications more feasible and sustainable.…”

Summary Small‐scale‐liquefied natural gas (LNG) cold‐utilized power generation systems are the sustainable solutions in the rural and inland areas where the large‐scale power generation is infeasible. This study investigates three different small‐scale LNG cold‐utilized power generation systems, which are called as the single, combined, and carbon dioxide (CO2)–reduced combined systems according to their design details. The assessments are done according to the life‐cycle‐based enviroeconomic and life‐cycle‐integrated thermoeconomic assessment (LCiTA) models that are recently developed and new approaches, in order to better monitor their feasibilities in real operations. The life‐cycle‐based enviroeconomic assessment shows that the combined system has the lowest environmental payback period with 7.35 years that is nearly 6 months and 1 year lower than the single and CO2‐reduced combined systems, respectively. The LCiTA study deduces that the combined system has the minimum levelized product cost while the single system has the highest values. The integration of CO2 capture components increases the levelized product cost nearly by 16.0% in the combined design, but the levelized product cost value is still found lower than the single system. Moreover, the sustainability performance of the systems is evaluated according to the improved sustainability index calculated by the life‐cycle‐integrated fuel and destruction costs. The index value of the combined system is twice that of the single system. The multiobjective optimization study is performed in cases of closed operation rooms. The best trade‐off points are found in the close ambient air temperature range between 300.50 and 302.00 K. To observe the dynamic outdoor performance, the finite sum approach is applied for the LCiTA model. The highest fluctuations are seen for the CO2‐reduced combined system while the smallest fluctuations belong to the combined system.
