The maritime industry must shift towards renewable marine fuels in order to ultimately phase out emissions entirely before the end of this century. C-Job sees hydrogen-based renewable fuels as the best solution to reduce greenhouse gas emissions in the maritime industry. Research into hydrogen-based renewables first started in 2016 when C-Job identified ammonia as one of the high potential fuels. Since then, we have also explored renewable fuels such as methanol via the Green Maritime Methanol consortium.

C-Job currently believes the future holds a combination of the following fuels:

  • Batteries
  • Hydrogen (H2)
  • Ammonia (NH3)
  • Methanol (CH3OH)
  • And more

For each of these, we are currently researching the possibilities and applications possible in the maritime industry. Additionally, to support the energy transition, C-Job feels that methods to support fuel savings such as wind-assisted propulsion in combination with a performance prediction program for Flettner rotors can be of great interest to the maritime industry.

“As every type of ship has a different operational profile, there is no one-size-fits-all in terms of carbon-free/neutral fuel. C-Job has the essential knowledge, thanks to our R&D investments, to support ship owners in the decision-making process to make their fleet more sustainable. This does not only regard analyzing and selecting the correct means of energy storage, such as batteries, hydrogen, ammonia, and methanol. It is also applying the respective solution in an optimal way and include means of energy-saving.”

“If you have one Flettner Rotor operating in moderate winds from a favorable direction, you can already achieve a sizable 25% fuel reduction. Of course, it is important to look at the bigger picture. Conditions are not always favorable, which leads to lower savings in average wind conditions.”
