How to decarbonize your ship - Large Fishing Trawler

Case study for a trawler to which shore power, hybrid-electric ESS and biofuels are applied

This is a techno-economic case study of a fishing trawler on which three technologies are applied for decarbonization purposes. These are shore power, a battery hybrid electric energy storage pack and biofuels. For this case study a battery pack used for spinning reserve in a hybrid setup is not economically feasible, but ships with other operational profiles or equipment usage might be benefitted significantly. It could also serve as an alternative to shore power, when there is no infrastructure available and your vessels needs to comply to strict port regulations. Use the Decarbonizer below to determine if it would benefit your vessel.

  • Case study is ‘Jacobus Maria’, a fishing trawler operating in North-Western Europe with 1 MW installed engine capacity.

  • 20% CO2 reduction has been assumed of which half is due to the use of biofuels (HVO).

  • CAPEX for all technologies are at least €1M, of which 80% is due to the battery hybrid battery pack. Roughly 10% CO2 reduction could be achieved with only €50k or so, and additional premium on the use of HVO.

  • OPEX cost for operating the vessel are reduced by €500 per day on average, leading to a payback rate of 5 years. This is a very unlikely scenario however, as EU ETS carbon taxes are assumed €300+.

Ship type considerations - Fishing

  • Fishing vessels are for the most part excluded from many rules and regulations on sustainability, including very strict regulations such as FuelEU and EU ETS (carbon tax in EU). It is not unthinkable that fishing ships will be included in the future, but this would be several years in the very least.

  • Shore power is always advised for ships that frequent ports with sustainability ambitions. Even when not currently mandated, it can be expected that shore power becomes obliged for all vessels in North-western Europe.

  • Battery hybrid solutions are generally (economically) feasible with average engine loads below 50%, or for diesel-electric ships with a variety of equipment used for non-propulsion purposes. This could be the case for larger trawlers or fish factories, that have much auxiliary equipment for fish processing on board. A sufficient battery pack would at the same time provide a solution for shore power.

  • Biofuels would most likely be (part) of the decarbonization mix for the foreseeable future, and it is therefore always advised to start with a biofuel blend to gain experience and increase blend ratio when need arises.
