Ammonia as a marine fuel

Prospects for the shipping industry

Key takeaways

Two low-emissions pathways exist for producing ammonia today

  • Low emission ammonia is produced from hydrogen that is generated by either of two processes:
  1. Blue hydrogen: Conventional methane reforming, combined with CO2 capture and storage
  2. Electro-ammonia: Electrolysis of water, powered by renewable sources
  • Grey ammonia has been excluded from the following analysis, because its price and emissions are higher than those of LSFO.
