Can IMO Policies Accelerate the Transition to E-Fuels in Shipping?

January 31, 2025

The maritime sector is at a critical juncture as it seeks to reduce greenhouse gas (GHG) emissions and transition to more sustainable energy sources. The International Maritime Organization (IMO) has been at the forefront of this effort, exploring various strategies to promote the adoption of e-fuels. A recent report by the UCL Energy Institute Shipping and Oceans Research Group, in collaboration with UMAS, delves into the effectiveness of these strategies and the challenges they face.

Evaluating IMO’s Current Strategies

The Role of Global Fuel Standards

The IMO has considered implementing a global fuel standard as a means to drive the adoption of e-fuels. However, the report highlights potential inadequacies in this approach. A global fuel standard, even when combined with a flexibility mechanism, may not be sufficient to initiate a significant shift to e-fuels before 2040. This is primarily due to the economic competitiveness of e-fuels, which remains a significant barrier. The report suggests that the looming threat of cost-competitiveness hinders the early adoption of e-fuels, thereby risking continued reliance on conventional fuels.

Moreover, the rigidity of a global fuel standard fails to account for the varying economic capacities and technological readiness of different countries and shipping operators. This one-size-fits-all approach does not allow for the nuanced encouragement needed to stimulate e-fuel adoption across disparate maritime stakeholders. To address this issue, the IMO needs to consider more flexible and inclusive methods, enabling various actors within the shipping industry to adopt sustainable practices without facing prohibitive economic pressures.

The Need for Targeted Incentives

To overcome the economic challenges, the report emphasizes the importance of targeted incentives, such as subsidies. These incentives are crucial for making e-fuels competitive from 2027 to 2035. Without such measures, the shipping industry may continue to rely on less sustainable fuel options, delaying the energy transition. Targeted incentives could be the key to bridging the economic gap, thus making e-fuels a viable alternative for the shipping sector within the suggested timeline.

The report predicts that without additional incentives, e-fuels will struggle to achieve cost competitiveness, which means the environmental and economic benefits of the energy transition could be significantly delayed. By offering subsidies that defray the higher costs associated with e-fuels, policymakers could stimulate early adoption and significantly cut down on GHG emissions from shipping. These economic tools are essential to expedite the industry’s energy transition and ensure that sustainable fuel options are not just available but financially feasible for shipowners worldwide.

The Economic Viability of E-Fuels

Predicting Cost-Effectiveness

The report predicts that by 2036, ammonia dual-fuel ships, initially operating on blue ammonia, will represent the most cost-effective solution. However, focusing on short-term competitiveness could lead to significant risks, such as technology lock-in and asset value volatility. Shipowners are advised to consider longer time horizons to avoid these pitfalls and ensure a smoother transition. By looking beyond immediate cost savings, stakeholders can make more robust investment decisions that align with long-term sustainability objectives.

Additionally, investing in technologies and infrastructure that support ammonia and other e-fuels could prevent a scenario where the industry becomes overly dependent on one solution. This diversification minimizes the risks of technology lock-in and cushions the financial impact of fluctuating fuel prices. Hence, while ammonia might present a cost-effective solution in the mid-2030s, the maritime sector must remain agile and forward-thinking to adapt to evolving technologies and market conditions.

The Impact of Levy Scenarios

Different levy scenarios play a crucial role in determining the competitiveness of e-fuels. A low-levy scenario, generating between $30 to $120 per tCO2e, may not provide adequate promotion and could compete with funds intended for just and equitable transitions. In contrast, a high-levy scenario of $150 to $300 per tCO2e is more likely to ensure sustained progress towards the energy transition. Higher levies help create a more predictable economic environment, enabling shipowners to make informed decisions when investing in new technologies and fuels.

For high-levy scenarios, the report suggests that a reward rate of $28 per GJ in 2027 is necessary to guarantee e-fuel competitiveness. This contrasts with $36 per GJ in low-levy scenarios, highlighting the efficiency of higher levies in reducing the needed reward rates. Even with flexibility mechanisms, high targeted rewards are essential to secure e-fuel competitivity. Policymakers must carefully balance the levy rates to ensure that they drive the desired behavioral changes without imposing undue financial burdens on shipping operators.

Policy Recommendations for Early Adoption

The Importance of High Targeted Rewards

For high-levy scenarios, the report suggests that a reward rate of $28 per GJ in 2027 is necessary to guarantee e-fuel competitiveness. This contrasts with $36 per GJ in low-levy scenarios, highlighting the efficiency of higher levies in reducing the needed reward rates. Even with flexibility mechanisms, high targeted rewards are essential to secure e-fuel competitivity. By providing direct financial incentives, policymakers can encourage shipowners to adopt e-fuels earlier, accelerating the industry’s transition to cleaner energy sources.

These targeted rewards must be strategically designed to address the total cost of ownership (TCO) gap between e-fuels and other low-cost compliance options. Ensuring that subsidies are appropriately sized and timed will be crucial for maximizing their effectiveness. Additionally, monitoring and adjustments to the incentive structures should be regularly conducted to reflect changes in market dynamics and technology advancements, thereby maintaining the momentum towards the broader adoption of e-fuels.

Regular Policy Reviews

Given the volatile nature of assumptions and forecasts, the report advocates for regular reviews of policies and reward mechanisms. These reviews, preferably conducted annually, are crucial for ensuring ongoing alignment with IMO’s targets and the cost-effective promotion of the energy transition. Adjustments to assumptions, such as CCS capture rates and biofuel prices, can significantly influence the competitive landscape of available fuels. Maintaining a dynamic policy framework allows for the swift adaptation to emerging trends and challenges, ensuring the strategies remain relevant and effective.

Furthermore, the sensitivity of scenario modeling to specific input changes necessitates a robust review mechanism. Regular policy evaluations will help identify any deviations from anticipated outcomes, allowing for timely corrections and the implementation of contingency plans. This proactive approach ensures that the maritime sector stays on course towards achieving its GHG reduction goals and fosters a resilient energy transition strategy that can withstand economic and technological fluctuations.

The Future of Ammonia as a Fuel

Mid-2030s and Beyond

Ammonia, particularly blue and subsequently e-ammonia, is highlighted as a formidable fuel/technology option from the mid-2030s. The report underscores the necessity of considering ammonia within the broader fuel mix to achieve long-term sustainability goals. The least cost-effective period extends through the 2040s, necessitating the adoption of e-fuels to minimize operational costs over the long run. Incorporating ammonia into the maritime fuel landscape offers a promising pathway to durable and significant emissions reductions.

The report emphasizes that ammonia’s potential hinges on the development of the necessary infrastructure and supply chains. Investments in ammonia production, storage, and distribution networks will be critical to realizing its widespread use. Moreover, continued research and development into technologies that improve ammonia’s safety and efficiency as a fuel will bolster its viability as a central component of the maritime sector’s energy transition strategy.
