The role of combustion engines in decarbonization – seeking fuel solutions

With the current focus on alternative marine power sources, it’s easy to overlook the overwhelmingly dominant position of the internal combustion engine, or ICE, in marine propulsion. The marine two-stroke ICE is so well proven and so well established that it will continue to have a central place in ship propulsion for decades to come.

If demands for decarbonization in shipping are to be met, the question then becomes one of fuel: which fuels can be green enough, and available soon enough, to satisfy stricter emissions regulations, and how will engine makers adapt to the new norm of fossil-free fuel?
