Hydrogen technology is among an unprecedented range of engine and fuel gas supply systems that Wärtsilä is developing to help ship owners navigate the route to reduced greenhouse gas emissions.
As shipping seeks to drastically cut emissions, which fuels it will use to do so are far from clear. For 100 years the marine fuel market has been dominated almost entirely by oil. Now a diverse palette of potential clean fuel is emerging.
The viability of many new fuels depends on overcoming many challenges over the next 10 to 20 years. But the urgency of shipping’s decarbonisation ambition – notably, the International Maritime Organization’s aim to cut total greenhouse gas emissions at least in half by 2050 – means there is no time to wait for the ideal solution. The answer lies in flexibility, says Mikael Wideskog, General Manager, Technology Strategy & Innovation, Wärtsilä Marine.
“There are uncertainties around every prospective fuel, including when and where they will be available and at what price. Building fuel flexibility into new vessels – and, where appropriate, retrofitting flexible powerplant in older vessels – offers a hedge against these risks.”
