“…According to LR/UMAS (2020) [7], maritime infrastructure is ready for second-and third-generation biodiesel, e-diesel, bio-LNG, and e-LNG. However, the price of such fuel is significantly higher compared with that of fossil fuels [8]; according to 2020 data, the prices of e-diesel, biodiesel, and bio-LNG are 1280%, 260-400%, and 500% higher compared with that of fossil fuels, respectively. The use of methanol on ships is in the initial stage of practical solutions [2,5], and ammonia and hydrogen are in the stage of pilot technological solutions [5,7].…”

The decarbonization of maritime transport has become a crucial strategy for the adoption of renewable low-carbon fuels (LCFs) (MARPOL 73/78 (Annex VI) and COM (2021) 562-final 2021/0210 (COD)). In 2018, 98% of operated marine diesel engines ran on fossil fuels. The application of LCFs, according to expert assessments (DNV GL), is considered the most effective solution to the decarbonization challenge in the maritime sector. This publication presents methodological proposals related to assessing the reliability of operational diesel engines when transitioning to low- carbon fuels. The proposed methodology implements an interconnected assessment of the combustion cycle parameters and the limiting reliability factors of the thermal load on the most critical components of the cylinder–piston group. The optimization of the combustion cycle parameters for the indicators of energy and the environmental efficiency of low-carbon fuel applications was combined with the evaluation and assurance of permissible values of the thermal load factors on the components to determine the overall reliability of the engine. Thus, the possibility of overload and engine failures was already eliminated at the retrofitting design stage. The algorithm for the parametric analysis was grounded in the practical application of established α-formulae for the heat exchange intensity, such as those of the Central Diesel Engine Research Institute and G. Woschni. This approach was combined with modeling the combustion cycle parameters by employing statistical or single-zone mathematical models such as IMPULS and AVL BOOST. The α-formulae for low carbon fuels were verified based on the thermal balance data. The structure of the solutions for the effectiveness of the practical implementation of this methodology was comprehensively oriented towards diesel “families”, as exemplified by the models 15/15 (pmi = 1.2, 1.4, and 1.6 MPa). The long-term goal of the obtained results in the structure of comprehensive decarbonization research was to assess the factors of the reliable operation of characteristic groups of medium-speed (350–1000 rpm) and high-speed (1000–2100 rpm) marine engines for reliable operation in the medium term on ammonia.

Fossil fuel combustion is a major source of Greenhouse Gases (GHGs), which cause global warming. To prevent further increases in anthropogenic GHGs, the global community needs to take action in each segment of the economy, including the shipping sector. Among different measures for reducing shipping emissions, the most promising one is the replacement of conventional marine fuels with alternatives. According to the International Maritime Organisation’s regulations, ships engaged in international shipping need to reduce their annual emissions by at least 50% by 2050. However, this does not apply to fishing vessels, which are highly dependent on fossil fuels and greatly contribute to air pollution. This paper investigates the environmental footprint of a fishing vessel (purse seiner) through the implementation of various alternative fuels. Within the research, Life-Cycle Assessments (LCAs) and Life-Cycle Cost Assessments (LCCAs) are performed, resulting in life-cycle emissions and lifetime costs for each alternative, which are then compared to a diesel-powered ship (baseline scenario). The comparison, based on environmental and economic criteria, highlighted methanol as the most suitable alternative for the purse seiner, as its use onboard resulted in 22.4% lower GHGs and 23.3% lower costs in comparison to a diesel-powered ship.

Explaining differences in policy learning in the EU "Fit for 55” climate policy package

Through learning, policy actors can maintain, reinforce, or revise their beliefs and positions about the design and outcomes of policies. This paper critically analyzes factors influencing policy learning by comparing policy processes of two EU laws of the recent “Fit for 55” climate package: (i) revised provisions on increasing energy efficiency in companies included in the recast Energy Efficiency Directive and (ii) the new FuelEU Maritime regulation provided for decarbonizing maritime shipping. Learning across coalitions with competing beliefs was encountered in the first case but not in the other despite similar institutional settings. The difference is attributed to a more politicized debate on decarbonizing shipping, leading to consensus through bargaining instead of deliberation, and a circumscribed leader of one coalition, with a less flexible negotiation mandate. The paper adds to the theory on policy learning, suggesting that levels of politicization and polarization, as well as the mandates of the coalition leaders, influence cross‐coalition learning.
