Ship owners increasingly face complex investment decisions as they try to navigate the most efficient course to the low-carbon future. Ever since the IMO set the industry’s ambitious emission-reduction targets for 2030 and 2050, owners have been inundated with information about future fuels and technologies that may, or may not, ultimately lower the carbon footprints of their fleet.Some of the new technologies hold promise, but the day-to-day viability of too many of them remains unproven; the same can be said for many of the potential fuels.

Ammonia, the same pungent solution used in fertilizers and cleaning agents, may one day be the key to transporting renewable energy around the world. There are currently a number of government and corporate projects assessing the feasibility of converting excess renewable energy from sources like wind, solar, tidal and nuclear into ammonia and then back into usable energy.In its purist form, ammonia or NH3 is composed of one nitrogen and three hydrogen atoms making it an ideal candidate to chemically bind excess renewable energy.

Systems integrator and equipment maker Rolls-Royce has quietly been adding hybridizing energy-storage packages to a diverse list of vessels. Yet, so, too, has one of its clients — Louisiana-based SEACOR Marine, as it reacts early to tightened emissions and energy-management standards, or EMS, for vessels plying Europe and North America. Fuel savings and energy-company clients seeking green credentials are, it turns out, just part of the upside driving battery retrofits.The fuel savings to be had for keeping thrusters on battery power are a powerful selling point, to be sure.
