Maritime transport is considered the most difficult sector to decarbonize in the transport sector. Similar to aviation, electrification is not (yet) a solution due to the lack of battery technologies with sufficient capacity. Alternative lower-emission propulsion options such as hydrogen, synthetic fuels, or ammonia are being tested but are not yet marketable. However, the maritime sector is still lagging well behind aviation in other areas as well.
