Shipping is one of the most efficient transportation modes for moving freight globally. International regulations concerning decarbonization and emission reduction goals drive rapid innovations to meet 2030 2050 greenhouse gas targets. The internal combustion engines used marine vessels are among energy conversion systems. Internal dominate propulsion system architectures shipping, current will continue serve several decades. However, aggressive low-carbon-intensity there an impetus further...
The phasing out of fossil fuels in the shipping sector is key importance for reducing greenhouse gas emissions. Synthetic based on renewable energy are a promising option sustainable maritime sector, with methanol being one most widely considered carriers. However, availability still limited and costs associated it significantly higher than conventional fuels, also because fuel synthesis must rely carbon dioxide as resource. Through use onboard capture, release during combustion can be...
<div class="section abstract"><div class="htmlview paragraph">Internal combustion engines (ICEs) will continue to be critical propulsion systems for certain applications in the coming decades. It is, therefore, extremely important further develop environmentally friendly and sustainable internal engines. These developments include, but are not limited to, improved tribology reduced mechanical losses, higher mean effective pressures, compatibility with carbon-free or -neutral...
Quantitative planar laser-induced fluorescence measurements of fuel/air mixing in engines are usually based on the use tracers. The strength signals often depends temperature, pressure and mixture composition. This complicates a quantitative analysis. small-bore optical engine for fundamental studies absorption properties tracers is described. composition dependence spectra toluene, acetone, 3-pentanone, biacetyl examined under motored conditions to extend experimental data base development...
Energy storage is one of the big challenges for energy transition and ammonia as a hydrogen carrier considered promising candidate efficient medium‐ to long‐term chemical storage. Gas engines are well suited power generation using carbon‐free fuel, making it unnecessary convert back utilization in plant. This study investigates operating strategies prechamber combustion concept large‐bore gas engine suitable applications. To overcome high ignition low laminar flame speed ammonia, different...
The HyMethShip project (Hydrogen-Methanol Ship propulsion using on-board pre-combustion carbon capture) is a cooperative R&D funded by the European Union’s Horizon 2020 research and innovation program. aims to drastically reduce emissions while improving efficiency of waterborne transport. system will achieve reduction in CO2 up 97% practically eliminate SOx particulate matter emissions. NOx fall over 80 %, safely below IMO Tier III limit. In this study concept introduced various aspects...
For applications of planar laser induced fluorescence (PLIF) to measure the fuel or equivalence ratio distributions in internal combustion (IC) engines it is typically assumed that addition a tracer base does not alter performance. We have investigated impact on performance through various amounts 3-pentanone toluene iso-octane fuel. Correlations between for range fuel/tracer mixtures and engine parameters, like peak pressure, location indicated mean effective pressure (IMEP), burn rate are...
One potential method to decarbonize the maritime transport sector is by using onboard carbon capture technologies. such future propulsion system HyMethShip - Hydrogen-Methanol Ship pre-combustion concept. In this study we use life cycle assessment analyse impact of design choices on overall environmental performance system. Using a vessel shown lower climate compared today’s conventional The runtime and hydrogen leakage are indicated as main influencers besides efficiency. cost higher than...
Abstract Renewable hydrogen (H 2 ) will play a pivotal role in the decarbonization of energy and industrial sectors. However, during transition to clean system, production H with electrolysis runs risk increasing carbon dioxide (CO emissions if electricity system is still partly based on fossil fuels. The European Union has set ambitious targets for defined strict rules delegated acts Energy Directive, when produced public grid can be counted as renewable. This paper analyzes two criteria...
The balancing of the electric grid has become more challenging due to expansion fluctuating renewable energy sources for power generation. importance plants driven by internal combustion engines will increase since they can react flexibly and quickly changes in demand. With regard emission pollutants CO2, gas fueled are favored gensets. However, it is meet dynamic load requirements with a engine than conventional diesel because acceptance limited occurrence knocking combustion. Dual fuel...
HyMethShip is a marine propulsion concept featuring methanol-based closed-loop carbon cycle with on-land methanol synthesis using hydrogen and dioxide onboard decomposition to used for be recycled. This combines the benefits of well-known liquid fuel bunkering storage emission-free combustion in large-bore engines. The has potential reduce CO2 emissions by more than 95 % while virtually eliminating sulfur oxide particulate matter reducing nitrous (NOX) below Tier III levels. In this study an...
