Since it was established in 2013, SGMF has been a pioneer in shaping the industry’s approach to methane/LNG. At present, its mandate encompasses a variety of new low and zero carbon marine fuels, providing guidance for the use of methanol, ammonia, and hydrogen. This expansion aligns with the evolving landscape of the marine fuel mix.

SGMF has produced a range of free resources on the safe use of methanol, ammonia, and hydrogen to help the industry in its transition towards a more sustainable future.

Here you will find a number of free resources to help to facilitate the transition towards a more sustainable future.
