Sustainable Marine Fuel Concentrates (SMFCs) are emerging as pivotal solutions in the maritime industry’s transition towards decarbonization. These fuels, derived from renewable sources such as biomass, synthetic fuels, and hydrogen-based compounds like ammonia and methanol, aim to significantly reduce greenhouse gas (GHG) emissions from shipping activities. The global maritime sector, responsible for approximately 3% of total GHG emissions, is under increasing pressure to adopt cleaner fuel alternatives to meet international environmental standards.

Regulatory measures have been primary catalysts. The IMO’s global sulfur cap (2020) and its Data Collection System (DCS), implemented in 2019, require vessels to report fuel consumption and carbon intensity, enabling enforcement and benchmarking. In July 2023, the IMO set non binding targets to reduce shipping emissions by 40% by 2030 and introduced a planned global carbon pricing mechanism by 2027 under its GHG strategy.

Government initiatives play a crucial role in accelerating the adoption of Sustainable marine fuel. For instance, the U.S. Department of Energy’s Bioenergy Technologies Office (BETO) is actively engaged in research to enhance the viability of marine biofuels. The U.S. maritime industry consumes an estimated 105 billion gallons of fuel annually, a figure projected to double by 2030 due to expanding global trade. BETO’s efforts aim to increase the production of marine biofuels to meet this rising demand, thereby supporting the industry’s decarbonization goals.

The EU has adopted Regulation (EU)2023/1805 (September 2023), mandating the incorporation of renewable and low-carbon fuels in maritime transport. Additionally, FuelEU Maritime, effective January 2025, will require a 2% reduction in GHG intensity, escalating to 80% by 2050. KPI OceanConnect plans to expand marine biofuel availability to 120 ports to meet demand driven by this policy.

Corporate strategies complement regulations. A.P. Moller Maersk aims to procure 15–20% of its fleet fuel from alternatives by 2030, up from 3% in 2023, focusing on biodiesel, green methanol, and biomethane. Private-sector alliances, such as launch of biomethane-fueled ships by Hapag-Lloyd and backing from the Zero Emission Maritime Buyers Alliance, aim to prevent 82,000 tCO over two years.

Technological innovation bolsters adoption marine biofuels can deliver 70%+ well-to-wake emissions reductions, and drop-in biofuels are compatible with unmodified engines. Hydrogen and ammonia are projected to comprise 60% of maritime fuel mix by 2050 under the IEA’s Net-Zero Emissions scenario, with biofuels accounting for 20%.

Emerging Trends

Rise of Green Ammonia and E‑Methanol in Sustainable Marine Fuel

The shipping industry is increasingly shifting toward green ammonia and e-methanol as key sustainable marine fuels. In June 2025, the International Maritime Organization (IMO) agreed to enforce carbon pricing—approximately US $100 per tonne of CO2 equivalent—from 2028. This policy is expected to significantly boost demand for zero-carbon fuels such as green ammonia and methanol.

Governments are actively supporting this transition. For instance, the U.S. Department of Energy has proposed a formal definition for sustainable maritime fuel by 2025 and is promoting pilot initiatives under its Zero-Emission Shipping Mission. These efforts include funding for clean ammonia and methanol technologies.

A prominent example is Fortescue’s Green Pioneer, an ammonia diesel mixed cargo vessel. It docked in London in March 2025 as part of King-Charles’s Sustainable Markets Initiative, aiming to eliminate fossil fuel use by 2030 and reduce CO2 emissions—shipping accounts for roughly 3% of global emissions—by more than 90%.

Furthermore, Maersk has commenced operations with e-methanol from its e-methanol facility in Denmark, producing 42,000 tonnes (53 million litres) annually. Another U.S. project in Texas received USD 100 million to build a Power to X plant capable of 300,000 tonnes/yr e-methanol production—reducing CO2 by over 90% compared to fossil fuels.

Consumer goods industry participation is also notable. Through the Zero Emission Maritime Buyers Alliance (Zemba)—whose members include Amazon, Patagonia, Mondelez, Tchibo, Nike, Levi Strauss, and Ikea—companies have committed to purchasing clean-fuel shipping covering 1 billion container miles, preventing an estimated 82,000 tonnes of CO2 emissions over two years.

Drivers

The Shift Toward Reducing Carbon Emissions in the Marine Industry

One of the primary driving factors for the adoption of sustainable marine fuels is the growing pressure to reduce carbon emissions in the global marine industry. As international maritime trade continues to expand, the carbon footprint of shipping activities has come under intense scrutiny.

• According to the International Maritime Organization (IMO), shipping accounts for around 2-3% of global greenhouse gas (GHG) emissions, with the sector projected to contribute more if current trends continue.

Governments and industries are increasingly aligning on the importance of reducing emissions. In 2020, the European Commission set a target for the European Union’s shipping sector to reduce GHG emissions by 40% by 2030. Additionally, countries such as Norway have been pioneers in introducing policies to boost the use of alternative fuels. Norway, for instance, has set an ambitious target for all new ships operating in its domestic waters to be zero-emission by 2030. This proactive stance from governments has driven investments in research and development of sustainable marine fuels such as biofuels, hydrogen, and ammonia, which offer significant potential to reduce emissions.

The demand for cleaner, greener fuels is also increasing from the private sector. Leading shipping companies, such as Maersk, have pledged to decarbonize their fleet, further intensifying the market demand for sustainable fuel solutions. The shift is driven not only by regulatory pressure but also by the increasing availability and cost-effectiveness of alternative fuels.

• According to the International Energy Agency (IEA), the cost of producing sustainable marine fuels has dropped by 15-20% in recent years, making them more competitive compared to traditional marine fuels.

Restraints

High Production Costs of Sustainable Marine Fuels

One of the major factors restricting the widespread adoption of sustainable marine fuels is the high production cost. Despite the growing interest in cleaner alternatives to traditional marine fuels, the cost of producing sustainable fuels remains a significant challenge. This price disparity makes it difficult for shipping companies to make the transition to sustainable fuels, especially considering the highly competitive nature of the industry and the slim profit margins.

• According to the International Energy Agency (IEA), the production of biofuels, which are one of the primary alternatives to fossil-based marine fuels, costs approximately 50-70% more than conventional fuels.

Government incentives and regulations have been crucial in supporting the development of sustainable marine fuels. For example, the European Union has implemented the Renewable Energy Directive (RED II), which provides financial incentives to encourage the use of renewable fuels. However, the scale-up of sustainable fuel production is still hindered by limited infrastructure and the absence of large-scale production facilities, which further increases the costs. Without widespread infrastructure, it is difficult for shipping companies to source these fuels consistently at competitive prices.

Moreover, the higher costs of sustainable fuels make them less attractive compared to traditional marine fuels. The International Maritime Organization (IMO) has set targets for reducing greenhouse gas emissions from the shipping industry, but the adoption of sustainable fuels remains slow due to their higher price. The shipping sector is extremely price-sensitive, and without significant subsidies or advances in fuel production technologies, the switch to sustainable fuels may be delayed.

Opportunity

Expanding Government Support for Green Fuel Innovation

One of the most promising growth opportunities for sustainable marine fuels lies in the growing government support for green fuel innovation. Governments around the world are recognizing the environmental challenges posed by traditional marine fuels and are increasingly investing in the development and adoption of sustainable alternatives. This support is critical for advancing the production and use of sustainable fuels in the shipping industry.

For instance, the European Union has committed to making its maritime sector carbon-neutral by 2050 under its Green Deal. This includes funding research and providing financial incentives for the development of low-emission technologies and green fuels, such as hydrogen, ammonia, and biofuels.

• The European Commission has also implemented a “Fit for 55” package, which aims to reduce GHG emissions by 55% by 2030, creating a strong push for more sustainable fuels in the marine industry. In line with this, the EU is increasing funding for projects focused on alternative fuel infrastructure, ensuring that sustainable fuels become more accessible to shipping companies.

In addition, countries like Japan and South Korea have introduced aggressive policies to support the use of sustainable marine fuels. Japan has set a goal to increase the use of ammonia as a marine fuel, with plans to launch ammonia-powered vessels by 2025. This initiative is backed by government investments aimed at creating a global ammonia supply chain, which will significantly lower the cost of this sustainable fuel.

This growing government initiative creates a favorable environment for research, investment, and the eventual scale-up of sustainable marine fuel production, providing shipping companies with an opportunity to transition to more sustainable energy sources at a lower cost. The positive effects of such initiatives will not only help meet international climate goals but also offer significant long-term economic benefits by reducing reliance on fossil fuels.
