Sustainable fuels 
pyrolysis oil poster

In 2019, we invested in the start-up MASH Energy. They produce biofuel from agricultural waste after harvesting.   

For biofuel to be sustainable it is crucial that the harvesting of biomasses does not compete with food chains or the environment in any other way. Biofuel is therefore not an ideal way for shipping to decarbonise due to the availability of biowaste for its production. But it is a very cost-efficient supplement to fossil fuel until we have a sustainable fuel type in place, as it requires minimal/no changes to our ships. We are currently working towards testing MASH biofuel fuel on a DFDS vessel.

  • Even though biofuel will have tail pipe emissions, resulting in the release of noxious chemicals into the air, some reporting and accounting standards still deem biofuel to be carbon neutral - because it does not emit new carbon into the atmosphere
  • It can be used as a drop-in fuel, supplementing fossil fuel, E.g., 90 fossil fuel and 10% biofuel
  • It can be used as the necessary pilot fuel for burning hydrogen, methanol, and ammonia in combustion engines: both green ammonia and green methanol all need a pilot fuel to ignite the combustion in combustion engines


  • The availability of sustainable feedstock remain a challenge, due to the large and regular volumes of fuel we need to run our ships
  • As with any new and sustainable fuel, developing it for commercial operations is costly and time-consuming

Green Ammonia

Green ammonia can be sustainably produced from water, air, and renewable energy. It can be stored efficiently as a liquid.
