Green ammonia adoption in shipping: Opportunities and challenges across the fuel supply chain

Abstract:

Green ammonia is produced from renewable hydrogen with no direct CO2 emissions when combusted, making it an important option to interrogate. This research uses a mixed methods approach, including analysing shipping stakeholders’ perspectives, to consider the full range of factors relating to its deployment and use. The study emphasizes though that the on-ground realities of transitioning away from fossil fuels require significant developments across the entire fuel supply chain, which extends beyond considerations around ammonia’s technological viability and encompass changes needed to onboard and portside infrastructure, incentives to accelerate retrofit and fleet renewal, and recognition of risks posed by first-movers in the sector. This study states that with short timeliness associated with Paris targets, and anticipated rising costs of new fuel infrastructure, there is an imperative to implement mitigation policy that focuses on urgently reducing reliance on liquid fuels, while alternative fuel deployment is established at scale.
