Abstract
The maritime industry is undergoing an unprecedented and rapid transformation. As the backbone of global trade, the sector now faces the urgent challenge of transitioning to zero-emission vessels in response to mounting environmental pressures and regulatory mandates. A historical analogy, the shift from sail to steam unfolded gradually over the course of a century, shaped by a complex interplay of technological innovation, economic incentives, infrastructure development, military imperatives, and evolving trade demands. In stark contrast, the current transition must occur within a much shorter timeframe, underscored by the International Maritime Organization’s (IMO) target of achieving net-zero emissions from international shipping by 2050.
This paper argues that understanding the drivers, constraints, and adaptive strategies of past maritime energy transitions can offer critical insights for managing today’s decarbonisation challenges. While technological innovation remains essential, historical evidence suggests that adoption is equally dependent on regulatory frameworks, economic viability, and the availability of supporting infrastructure. The nineteenth-century proliferation of global coaling stations strategically located at ports such as Gibraltar, Aden, and Suez, was underpinned by military and imperial priorities, enabling steamships to displace sail on long-distance routes and reshaping global trade and naval power projection. Simultaneously, the so-called “sailing-ship effect” saw dramatic improvements in sail technology as designers responded to competitive pressure from steam, temporarily extending the commercial viability of wind-powered vessels.
Today, however, the absence of a comparable military or geopolitical imperative leaves the development of alternative fuel infrastructure largely at the mercy of regulatory enforcement and commercial risk appetites. This shift introduces a new layer of vulnerability, without coordinated public investment or strategic urgency, the pace of infrastructure deployment may lag technological readiness, undermining the feasibility of a timely transition. By analysing these historical precedents, this paper identifies key parallels and divergences that can inform contemporary policy and investment strategies. The lessons of the past, particularly the importance of coordinated infrastructure development, targeted policy interventions, and workforce adaptation, are vital for accelerating the adoption of zero-emission fuels and ensuring a just and economically viable transition for the maritime sector.
