A new study by academics at the University of College London (UCL) has found that investments in liquefied natural gas (LNG) and methanol as alternative fuels for shipping are diverting investment away from the long-term decarbonization pathway. The study, titled 'When is a stepping stone a dead-end? Insights into 'stepping stone' pathways from the maritime shipping transition,' developed a new analytical framework to assess whether near-term transitional fuels like LNG and methanol can genuinely enable a zero-emissions future system for shipping.
The researchers used a combination of interviews, documentary analysis, patent data analysis, and econometric analysis to examine the impact of investments in LNG and methanol on the shipping industry. They found that while these alternative fuels may generate some knowledge spillovers and procedural regulatory learning useful for green ammonia, the benefits are likely outweighed by capital lock-in and the entrenchment of fossil fuel infrastructure.
The study suggests that investments in LNG and methanol can create 'dead ends' in the transition to a sustainable future system. These dead ends may cut emissions in the short term but lock in fossil-based architectures and create stranded assets that compete with more sustainable solutions. This is because the development of new technologies and infrastructure for these alternative fuels can become locked into existing pathways, rather than being adaptable and transferable to other solutions.
The researchers also found that methanol is assessed as offering even weaker stepping stone characteristics than LNG, and may divert capital and political attention away from ammonia without providing durable system benefits. This highlights the need for policymakers to prioritize investments in green ammonia as a more sustainable solution for shipping decarbonization.
Dr. Pinar Langer, Research Fellow at the UCL Energy Institute Shipping and Oceans Research Group, noted that 'there is a real danger in confusing short-term movement with long-term progress.' He emphasized that investments in LNG and methanol can easily become dead ends if they lock capital, infrastructure, and expectations into pathways that do not lead to zero-emission shipping.
The study calls on policymakers to take two urgent steps. First, to build long-term credibility around emissions reduction goals so that ship investors price in the value of genuine ammonia-readiness. Second, to accelerate ammonia deployment through dedicated R&D funding, demonstration trials, and the development of robust safety standards – with the goal of establishing ammonia within commercial niches this decade.
The research also offers a broader contribution to the field of sustainability transitions, providing a conceptual framework applicable to other sectors weighing up transitional technologies. This highlights the need for policymakers to prioritize long-term thinking and strategic planning in their approach to decarbonization.
Investments in LNG and methanol may seem like a step towards decarbonization, but they can actually create path dependencies that divert attention away from more sustainable solutions. Policymakers must prioritize investments in green ammonia and other technologies that can drive meaningful progress towards a zero-emissions future.
The study's findings have significant implications for the shipping industry and policymakers alike. As the world transitions to a low-carbon economy, it is essential to prioritize long-term thinking and strategic planning in our approach to decarbonization. By doing so, we can ensure that investments in alternative fuels like LNG and methanol are aligned with our goals of reducing greenhouse gas emissions.
Ultimately, the transition to a zero-emissions future system for shipping will require a coordinated effort from policymakers, industry leaders, and researchers. The study's findings highlight the need for a more nuanced approach to decarbonization, one that prioritizes long-term thinking and strategic planning over short-term gains.
