The shipping industry is a critical pillar of global trade, accounting for roughly 3% of global greenhouse gas (GHG) emissions annually (IUMI, 2023). In response to mounting environmental concerns and stricter regulatory mandates, there is increasing pressure—from both international bodies like the International Maritime Organization (IMO) and regional authorities such as the European Union—to reduce emissions drastically by 2030 and achieve net-zero by 2050 (DNV, 2023).

One of the main pathways under consideration to meet these targets is the adoption of alternative marine fuels—such as LNG (liquefied natural gas), biofuels, methanol, ammonia, hydrogen, and synthetic fuels (Gupea, 2019). These fuels offer potential for lower emissions of CO₂, SOₓ, and NOₓ compared to traditional heavy fuel oil and marine diesel, but their uptake introduces new sets of technical, operational, financial, and regulatory risks (IntechOpen, 2021).

From a technical perspective, challenges include fuel storage, handling, bunkering infrastructure, engine compatibility, safety (for both crew and cargo), and supply chain consistency. For example, biofuels may suffer from microbial growth, sludge formation, or corrosion issues; ammonia and hydrogen pose hazards related to toxicity, flammability, and handling (AXA, 2022).

 On the regulatory side, codes such as the IGF Code (International Code of Safety for Ships Using Gases or other Low-flashpoint Fuels) have been introduced (effective from 2017) to govern safe usage of some alternative fuels, particularly LNG (Gard, 2022). Nevertheless, interim guidelines are being developed for other fuels like alcohols (methyl/ethyl), LPG, and ammonia, but many of these fuels lack long operational histories and standardized regulatory treatments (IMO, 2022).

From the insurance side, many of the risks are not yet fully quantified. Insurers and underwriters face uncertainty around the likelihood, severity, and nature of possible losses—for example, damage from untested fuel mixtures, failure of retrofitted systems, insufficient crew training, or environmental liabilities stemming from leaks or accidents. Premiums and policy terms may be adversely affected or may include new exclusions, higher deductibles, or surcharges (Marsh, 2022).

Economic and market challenges further complicate the picture: alternative fuels often come at higher cost, both in fuel price and in conversion or infrastructure investment; supply may be patchy in many regions; retrofit or newbuild costs may affect resale values; and uncertainties around regulations or insurance coverage can deter investment (Marsh, 2022).

In sum, while alternative fuels present a promising route toward decarbonising shipping, their adoption is hindered by a complex web of interlinked risks, regulatory gaps, market uncertainty, and insurance challenges. This thesis therefore focuses on examining these insurance implications as a key barrier to scaling up alternative fuel use, with the goal of proposing ways to adapt insurance and regulatory frameworks to better support a sustainable transition.

The shipping industry is under increasing global scrutiny due to its environmental footprint. Currently, maritime transport contributes approximately 3 % of global CO₂ emissions, and is responsible for sizeable amounts of sulfur oxides (SOₓ), nitrogen oxides (NOₓ), and particulate matter (PM), which harm both climate and human health (IUMI, 2023).

In response, international regulatory frameworks are evolving. The International Maritime Organization’s (IMO) Initial Strategy aims for significant reductions in greenhouse gas emissions from shipping, with goals such as limiting the carbon intensity and achieving net-zero emissions by around 2050 (Sciencedirect, 2021). Another major regulatory update was IMO 2020 which limited the sulfur content in marine fuel, via amendments to MARPOL Annex VI, and triggered industry-wide shifts in fuel sourcing and technology to comply (MDPI, 2024).

Parallel to regulatory change, public policy & market forces are pushing shipping companies to adopt alternative fuels—such as LNG, biofuels, methanol, hydrogen, and ammonia—to reduce emissions and meet both environmental targets and market expectations (IUMI, 2024). However, adoption is uneven: technological maturity, cost, supply infrastructure, engine compatibility, safety, and lifecycle emissions all vary significantly across fuel types. For instance, hydrogen and ammonia show strong potential in theory but pose serious challenges in storage, toxicity, flammability, or lack of robust bunkering and engine technologies (ReinAsia, 2024).

From the insurance perspective, the shift to alternative fuels introduces novel risk profiles. Insurers are concerned about issues such as fuel compatibility, new hazards (e.g. from leaks, explosions, toxicity), uncertainties in claim frequencies/severities, and ambiguous liability regimes for newer fuels or their handling. Also, the fleet of vessels capable of using alternative fuels is growing: data from Lloyd’s Register shows that as of 2024, there were around 1,737 newbuild vessels ordered with capability for alternative fuels, and ~3,597 total in service or on order.

Economic and lifecycle analyses indicate that while some fuels offer significant environmental benefit (e.g. methanol, ammonia in certain contexts), their overall cost of implementation—including fuel production, retrofitting/newbuilding, bunkering infrastructure, safety compliance, and possible higher insurance costs—may reduce their attractiveness without supportive regulation or insurance frameworks.

In summary, the background establishing this thesis is composed of:

• Rising emissions and environmental/health concerns from current marine fuels.
• Regulatory pressure (IMO, MARPOL, regional policies) demanding decarbonization.
• Technological developments and experimentation with alternative fuels, each with different strengths and risks.
• Insurance challenges: risk assessment, liability, safety, unknowns in operational histories, and economic implications.
• A gap in knowledge regarding how insurance can adapt to better facilitate adoption of alternative fuels, particularly in terms of contract design, risk-sharing, premium-setting, and regulatory alignment.
•   Aim and objectives

Aim:
This thesis aims to investigate how insurance-related issues act as barriers to the broader adoption of alternative fuels in the shipping industry, and to provide recommendations for adapting insurance frameworks to support the transition.

Research Questions:

• RQ1: What are the risks associated with the use of alternative fuels onboard ships—operationally, environmentally, and in respect of ship assets?
• RQ2: What impacts do these risks have on marine insurance instruments: policies, clauses, premiums, and overall contractual arrangements?
• RQ3: How can marine insurance frameworks be adapted (or reformed) to mitigate these risks and thereby reduce insurance-related barriers to adoption of alternative fuels in shipping?

Objectives:
To achieve the aim and answer these questions, the thesis will pursue the following objectives:

This research focuses on examining the insurance implications of adopting alternative fuels in the shipping industry. The central scope of the study is to analyse the risks associated with alternative fuels, their reflection in marine insurance policies and contractual arrangements, and the potential for adapting insurance frameworks to support decarbonisation.

The scope of this thesis includes the following dimensions:

This thesis is limited to examining risk and insurance-related dimensions of alternative fuels and does not delve into the detailed technical engineering of fuel systems or engine design. The primary aim is to address the knowledge gap regarding the intersection between alternative fuel risks and marine insurance frameworks in the shipping sector.

•   Theory

This section delves into the theoretical underpinnings and scholarly discourse surrounding the adoption of alternative marine fuels. It critically examines four pivotal domains: emissions reduction strategies, marine insurance dynamics, risk assessment methodologies, and the environmental impact on the maritime ecosystem.

1. Emissions Reduction and Decarbonization in Shipping

The maritime sector is a significant contributor to global greenhouse gas (GHG) emissions, accounting for approximately 3% of the global total )Wang Q, Zhang H, Huang J and Zhang P (2023).  In response, the International Maritime Organization (IMO) has set ambitious targets to reduce carbon intensity by at least 40% by 2030, compared to 2008 levels (Churchill et al., 2022; Tanaka, 2019) The 2023 IMO GHG Strategy emphasizes the adoption of zero or near-zero GHG emission technologies, including alternative fuels, aiming for a substantial reduction in the sector's carbon footprint.

Alternative fuels such as biofuels, ammonia, hydrogen, and methanol are being explored as viable options to replace conventional marine fuels. These fuels offer varying degrees of GHG emission reductions. For instance, biofuels derived from used cooking oil can reduce emissions by up to 90% on a life-cycle basis (Handrlica, 2019). However, the adoption of these fuels necessitates comprehensive life-cycle assessments to evaluate their environmental impact fully (Yadav and Jeong, 2022).

2. Marine Insurance and Emerging Risks

The transition to alternative fuels introduces new risks that challenge traditional marine insurance models. Insurers must assess the safety and compatibility of these fuels with existing vessel infrastructure. For example, ammonia, while promising as a zero-emission fuel, poses toxicity and corrosive risks, necessitating specialized safety measures (Handrlica, 2019).

Additionally, the evolving regulatory landscape requires insurers to adapt their policies to accommodate the unique characteristics of alternative fuels. The U.S. Coast Guard mandates that no bunkering of alternative fuels proceed without a prior risk assessment, highlighting the need for insurers to consider regulatory compliance in their risk evaluations (Balcombe et al., 2022).

3. Risk Assessment Methodologies

Quantitative risk assessment (QRA) has become a critical tool in evaluating the safety and feasibility of alternative fuels in maritime operations. QRAs facilitate the identification and mitigation of potential hazards associated with fuel storage, handling, and combustion processes. For instance, ammonia-fueled vessels require detailed risk assessments to ensure crew safety and operational reliability (Chang, 2020).

Furthermore, the integration of alternative fuels necessitates modifications to existing risk assessment frameworks to account for new variables such as fuel volatility, storage requirements, and emission profiles. This adaptation is essential to maintain safety standards and operational efficiency in the maritime industry.

4. Environmental Impact on the Maritime Ecosystem

The adoption of alternative fuels has profound implications for the maritime ecosystem. While these fuels can significantly reduce GHG emissions, their production and use may introduce new environmental challenges. For example, the large-scale cultivation of biofuel crops can lead to land-use changes, potentially impacting biodiversity and food security (Prussi et al., 2021).

Moreover, the introduction of substances like ammonia into marine environments raises concerns about potential toxicity to aquatic life. Therefore, a holistic approach, encompassing both the benefits and potential drawbacks of alternative fuels, is essential to ensure the sustainability of the maritime ecosystem.
