“…Methanol combustion in internal combustion engines (ICE), drastically reduces SO X and particulate matter (P M ) emissions [16], [27], [29]. When green or e-methanol is adopted [11] they provide a profound reduction in CO 2 emissions on a Wellto-Wake (WTW) scope.…”

“…Looking into the details of the engine many more variations can be observed. Methanol does not burn by itself, it requires a pilot fuel to achieve this [16]. As a result, variations can be found in the location in the process where methanol is mixed with the pilot fuel, but also the choice of pilot fuel and engine type (e.g.…”

“…This paper focuses specifically on methanol as a fuel, since it eliminates almost all SO X , drastically reduces N O X in comparison to conventional marine diesel [14], and can be produced in clean ways from biomass or water electrolysis. This means that it can potentially turn into an almost carbon neutral fuel [15], [16]. The environmentally clean versions of methanol, biomethanol and e-methanol, prove highly cost competitive in comparison to other alternative fuels [10].…”

The adoption of alternative energy carriers is one of the key ways to meet the increasingly stricter emission regulations faced by shipping vessels from the international maritime organisation (IMO) and European Commission. To support this objective, this study examines the challenges and uncertainties associated with implementing a methanol power propulsion and energy (PPE) system on the design of a vessel. This paper argues that new fuels, such as methanol, should be treatedas disruptive innovations due, in part, to the uncertainties surrounding their implementation. Their integration causes challenges regarding systems selection, layout design, and maintaining strict safety measures. In the case of methanol, current research treats the fuel as a system conversion based on diesel fuel. This paper provides a review of the state-of-the-art on the design of methanol fuelled vessels, and identifies a research gap related to the need for a new suitable design method for the design of ships integrating future alternatively fuelled PPE systems. A design approach inspired by model-based systems engineering integrating uncertainty modelling is proposed to examine the influence of uncertainty on the design of the vessels. The impact of uncertainty on the design is investigated through a case study of a simplified engine room layout utilizing a genetic algorithm to produce layouts for variable PPE systems dimensions within a MonteCarlo simulation.

“…The Well-to-Wake GHG emissions of e-fuels are very low compared to conventional fuels, and they encompass e-diesel, e-LNG, and e-methanol (which can all be used in existing vessels, and do not require large modifications), as well as e-hydrogen and e-ammonia (which do require the conversion of existing marine engines, or the delivery of newbuildings). With all e-fuels, there is also likely to be some additional investment required in new infrastructure [18][19][20][21].…”

The decarbonization of the shipping industry has risen to a new level of significance on the agendas of policy makers and strategic decision makers. This paper focuses on the likely cost implications for the shipping industry of recently implemented, and future planned policies that seek to reduce the carbon footprint of the sector. The scale of the problem is presented through a summary review of the International Maritime Organization’s fourth greenhouse gas study of 2020. The regulatory context, which is emerging as a response to overcoming this challenge, is analyzed at both the global and EU level. The potential cost implications for the future, in terms of this new regulatory context, are then analyzed on the basis of a review of academic and industry sources. Our paper concludes that alternative, zero-carbon fuels are the best way forward, but that operational and technological innovations will not be sufficient to bring about the complete decarbonization of the industry within the foreseeable future. Thus, market-based measures are required. Finally, the options available, and the likely implications of each of these options, is addressed, suggesting that there will be both winners and losers in the race to decarbonize the shipping industry.

“…However, integrating methanol into marine ICEs presents a significant challenge owing to its high latent heat of vaporisation [9]. Compared to diesel, methanol exhibits nearly half the lower heating value, adding another degree of complexity to its integration [11], [13], [14]. Consequently, longer injection duration and increased mass quantities are required to achieve the same power output.…”

Methanol has emerged as a cost-effective and scalable alternative fuel for the maritime sector. However, the use of methanol in marine engines is limited by the unknown characteristics of methanol sprays when introduced through retrofitted port fuel injection (PFI) systems. The present study investigates the characteristics of methanol sprays under relevant conditions for marine engines, such as low injection pressure PFI. The primary objective of this research is to advance knowledge into key spray characteristics, including spray penetration, droplet size, atomization quality, and evaporation. The proposed methodology evaluates the efficacy of state-of-the-art computational fluid dynamics (CFD) models in simulating PFI marine engine spray conditions. Moreover, the study compares the performance of the Kelvin-Helmholtz (KH-RT) and Taylor Analogy Breakup (TAB) droplet breakup models under low injection pressure conditions. The results demonstrated that the KH-RT model does not predict any droplet breakup occurrence suggesting that the TAB model is more suitable for the given conditions. Furthermore, the liquid penetration of the spray was observed to align with the outcomes reported in previous experimental literature on methanol sprays. Nevertheless, the droplet sizes for low pressure injectors appear relatively large, indicating poor spray atomization, which impedes rapid evaporation and increases the risk of wall wetting in the inlet manifold and combustion chamber.
