The global shift toward cleaner energy is reshaping the maritime industry. As pressure grows to meet net-zero targets, ammonia and methanol are fast emerging as key alternatives to traditional marine fuels. They promise reduced emissions and a path toward greener shipping, but they also introduce new safety challenges that seafarers must understand.

At Stream Marine Technical, we are helping crews prepare for this change through specialist New Fuel Technology training that focuses on the safe handling, storage, and emergency management of next-generation fuels.

The Rise of Alternative Marine Fuels

The shipping industry accounts for nearly 3% of global greenhouse gas emissions. To reach the International Maritime Organisation’s targets, vessels need to move beyond heavy fuel oil and even LNG toward zero-carbon fuels.

Methanol is already in active use on vessels worldwide due to its cleaner combustion and relatively straightforward storage. Ammonia is now being trialled as a fuel that can achieve true zero-carbon operation, provided it is produced using renewable energy sources.

Both fuels have huge potential but also bring risks that must be properly managed through training and preparedness.

Understanding the Risks

Methanol

Methanol burns with a nearly invisible flame, making fire detection extremely difficult. It is also toxic if ingested or inhaled, and its vapours can create flammable environments in enclosed spaces.

Ammonia

Ammonia poses a different set of hazards. It is highly toxic, corrosive, and can cause severe burns to the skin and respiratory system. A small leak in a confined area can quickly become life-threatening.

These risks mean that even experienced seafarers must update their skills and knowledge before working with these fuels.

The Importance of Safety Training

Handling methanol and ammonia safely requires a detailed understanding of how these fuels behave and how to react in an emergency. Traditional bunker handling procedures are no longer enough.

At Stream Marine Technical, our New Fuel Technology courses give crew members the opportunity to work through realistic fuel handling exercises, understand the safety systems onboard, and take part in emergency drills that replicate real-world incidents.

Delegates learn:

  • How to identify and contain leaks quickly.

  • Safe venting and purging procedures.

  • Correct use of protective clothing and respirators.

  • Emergency response to fire or exposure.

This kind of practical training ensures that safety becomes second nature, not just a box-ticking exercise.

Regulations and the Future of Training

As the use of alternative fuels expands, international regulations are evolving rapidly. The IMO’s IGF Code outlines requirements for ships using gases or low-flashpoint fuels, while classification societies and flag states are updating their safety guidelines to reflect new risks.

This means that training providers like SMT must stay ahead of the curve, ensuring courses meet the latest standards and reflect real operational challenges faced at sea.

Why Seafarers Should Prepare Now

The shift to alternative fuels is not a distant goal; it is already happening. Major shipping companies are launching methanol-powered vessels, and the first ammonia-fuelled ships are in advanced stages of development.

Crew who understand these fuels will be in high demand, as employers look for personnel who can safely manage operations under the new fuel codes. Gaining this training early gives seafarers a competitive edge in an evolving industry.

Recap

Methanol and ammonia will play a major role in the future of sustainable shipping. They bring environmental benefits but also serious safety responsibilities.

By training early, seafarers can ensure they are ready for this transition. Stream Marine Technical’s New Fuel Technology programmes equip crews with the skills, confidence, and understanding needed to handle these fuels safely and effectively.
