This paper presents a comprehensive Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) of onboard ammonia storage systems for shipboard fuel applications within the framework of the NH3CRAFT project. The LCA evaluates the environmental impacts of storage for both a demonstrator ship and desktop study ships, considering the entire lifecycle from raw material production to end-of-life disposal. Key environmental performance indicators, such as Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), and Photochemical Ozone Creation Potential (POCP), are quantified using established methodologies. For the LCCA, a robust methodology is proposed to assess the economic feasibility of ammonia storage systems, considering design, construction, operation, maintenance, and end-of-life costs. Results indicate that while composite tanks exhibit a higher initial investment, metallic systems demonstrate higher annual operation and maintenance costs. The analysis also considers non-quantifiable factors, including regulatory compliance and brand image. This study provides valuable insights for the maritime industry in evaluating the environmental and economic sustainability of selecting appropriate ammonia marine fuel storage solutions. Additionally, LCCA analyses for various desktop study ships (bulk carrier, tanker, container ship, RoPax ferry, double-ended ferry) using metallic tanks are presented, offering a broader understanding of life cycle costs across different vessel types.

摘要

This paper presents a comprehensive Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) of onboard ammonia storage systems for shipboard fuel applications within the framework of the NH3CRAFT project. The LCA evaluates the environmental impacts of storage for both a demonstrator ship and desktop study ships, considering the entire lifecycle from raw material production to end-of-life disposal. Key environmental performance indicators, such as Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), and Photochemical Ozone Creation Potential (POCP), are quantified using established methodologies. For the LCCA, a robust methodology is proposed to assess the economic feasibility of ammonia storage systems, considering design, construction, operation, maintenance, and end-of-life costs. Results indicate that while composite tanks exhibit a higher initial investment, metallic systems demonstrate higher annual operation and maintenance costs. The analysis also considers non-quantifiable factors, including regulatory compliance and brand image. This study provides valuable insights for the maritime industry in evaluating the environmental and economic sustainability of selecting appropriate ammonia marine fuel storage solutions. Additionally, LCCA analyses for various desktop study ships (bulk carrier, tanker, container ship, RoPax ferry, double-ended ferry) using metallic tanks are presented, offering a broader understanding of life cycle costs across different vessel types.
