Summary of "The Potential of Zero-Carbon Bunker Fuels in Developing Countries"

Core Content

This report explores the potential of zero-carbon bunker fuels in developing countries, focusing on the transition from fossil fuels to sustainable alternatives in the maritime sector. It evaluates the feasibility, scalability, and economic viability of various zero-carbon fuels, including biofuels, hydrogen, ammonia, and synthetic carbon-based fuels, and identifies which developing countries are best suited to become suppliers of these fuels.

Main Points

• Need for Zero-Carbon Bunker Fuels: The maritime industry must undergo a rapid energy transition to meet the International Maritime Organization (IMO) climate targets. These targets aim for a 50% reduction in greenhouse gas (GHG) emissions by 2050 compared to 2008 levels, with a goal to phase out GHG emissions entirely.

• Zero-Carbon Fuel Options: The report outlines four main zero-carbon fuel options: biofuels, hydrogen, ammonia, and synthetic carbon-based fuels. Each has distinct production pathways and environmental impacts.

• Green Ammonia and Hydrogen: Green ammonia and hydrogen are identified as the most promising options due to their low lifecycle GHG emissions, scalability, and compatibility with existing and emerging technologies. Green ammonia is produced from renewable electricity, while blue ammonia is derived from natural gas with carbon capture and storage (CCS).

• Preference for Ammonia Over Hydrogen: Ammonia is preferred over hydrogen due to its easier storage and handling, lower space requirements on ships, and the existing global supply chain for ammonia. However, its toxicity necessitates careful design and operational measures to ensure safety.

• Biofuels and Synthetic Fuels: Biofuels are unlikely to play a major role due to limited feedstock availability and high demand across multiple sectors. Synthetic carbon-based fuels, while chemically similar to fossil fuels, are economically unviable due to their energy-intensive production processes and high costs.

Key Information

1. Assessment Criteria for Zero-Carbon Bunker Fuel Production Potential

The report introduces a "Red-Amber-Green" (RAG) analysis to assess the potential of countries to supply zero-carbon bunker fuels. Five key criteria are used:

• Energy Resources Required: Availability of renewable energy or natural gas with CCS.
• Shipping Volumes: The volume of maritime traffic in the country.
• Geographic Location: Proximity to major shipping routes or ports.
• Regulatory Framework: Current and projected regulatory support for clean energy and CCS.
• Existing Infrastructure: Ability to leverage current energy and port infrastructure.

Each criterion is scored, and the results are combined into a weighted composite score to classify countries into three tiers: "High", "Promising", or "Limited or Insufficient Data".

2. Three Scenarios for Zero-Carbon Fuel Production

• Scenario 1: Countries well-positioned to produce blue ammonia or hydrogen (from natural gas with CCS).
• Scenario 2: Countries well-positioned to produce green ammonia or hydrogen (from renewable energy).
• Scenario 3: Countries well-positioned to produce blue ammonia/hydrogen initially, and then shift to green production.

3. Case Studies

The report includes four case studies, focusing on the production of ammonia (blue, green, or first blue then green) in the following countries:

• Brazil: Well-positioned for blue ammonia production due to its natural gas resources and CCS potential. Estimated demand for ammonia is between 2-9% of global shipping needs, with investment required between $24–$107 billion.

• India: Has significant renewable energy potential, particularly solar, and is well-suited for green ammonia production. It is projected to meet 10–27% of global shipping ammonia demand, requiring investment between $147–$385 billion.

• Mauritius: A small island developing state with interest in becoming a bunkering hub. It is well-suited for green ammonia due to its solar and wind resources. Estimated demand is 0.3–0.5% of global shipping needs, with investment required between $1.6–$2.7 billion.

• Malaysia: Positioned to initially produce blue ammonia and then transition to green ammonia. It has both natural gas resources and renewable energy potential. Estimated demand is 1–10% of global shipping needs, with investment required between $17–$138 billion.

4. Investment Estimations

The report provides estimates of the capital expenditures required to produce zero-carbon bunker fuels in the selected countries. These investments are crucial for the development of a sustainable maritime fuel supply chain and are expected to contribute to the economic growth of these countries.

5. Implications for Policymakers and Industry

• Policymakers should focus on developing supportive regulatory frameworks, promoting renewable energy, and investing in infrastructure that can accommodate zero-carbon fuels.

• Industry should consider the compatibility of these fuels with existing technologies and the potential for long-term cost reductions as renewable energy becomes more accessible.

Conclusion and Outlook

The report concludes that ammonia and hydrogen are the most viable zero-carbon bunker fuels for the maritime industry. Developing countries have the potential to become key suppliers, especially if they can leverage their renewable energy resources and existing infrastructure. The findings suggest that a strategic approach to transitioning from blue to green fuels is necessary for long-term sustainability. Future work should focus on refining these assessments, exploring additional countries, and developing detailed investment plans.
