CONCLUSION
For many shipowners, finding capital to fund proven fuel saving technologies can be a challenge – even for technologies that pay for themselves in a matter of years.
LNG fuel technologies can improve environment friendly transportation but still there can be some challenges like: bunkering challenges - onshore bunkering logistics are still under development, LNG fuel pricing challenges, additional rules still under development, and public notice not fully known.
Biofuel can be a good alternative way for fuel technologies. It is environmental friendly, can be mix with accredited fossil fuels to power internal combustion engines. Biofuel fuel can be produced almost anywhere. One of the challenges can be to provide the necessary product volume. Increasing processing will either increase costs of biofuel. Also water resources can be one of the biofuel challenges, sharing the drinking water and water for irrigation systems. And last but not less important challenge can be weather, there might be some problems to start engine at the cold weather, so it is important to know in which area vessel will fly to avoid this kind of conditions.
Electrification and renewables main challenge is how to better save the energy on batteries. Mostly the batteries have heavy weight, limited driving range and need some recharging time. Normal recharging takes several hours and that is what must be taken into the account.
