-Slow steaming and emission control (EEDI, EEXI)
-SCRs/EGRs
-LSFO (Scrubbers are no perspective)+ improved cylinder lubrication.
-Wide application of low carbon fuels LNG, CNG, LPG
-Alternative low carbon fuel-MeOH
-Alternative no carbon fuels-NH3 (Hydrogen is no perspective till now)
-Automation
-Dual fuel engines (LNG is probably the best fuel for future)
-New generation of diesel engines (full electric battery propulsion and fuel cells are no perspective for wide application)
