PROVEN

Used for decades in industry – safe to produce, store and transport

GREEN

Hydrogen can be made from renewable energy CO2 free through electrolysis

CLEAN HYDROGEN

Clean hydrogen has been identified as an important fuel for decarbonising the maritime sector

MARINE FUEL CELL

EMERGING TRENDS

  • Increasing pollution regulations: inland waterways and restricted zones
  • Increasing global electric motor boat market
  • Falling costs of renewables to enable green hydrogen: 80% decrease in renewable energy prices since 2010
  • Demand for clean hydrogen predicted to grow by over 8-times before 2050

GLOBAL REGULATION

  • Paris Agreement & Net Zero: +66 countries have 2050 net zero targets
  • International Maritime Organisation: CO2 reductions of 40% by 2030 and 70% by 2050
  • Global Maritime Forum: Industry pressure for ZEVs by 2030
  • Hydrogen Council: +90 members

HYDROGEN SUITABILITY

  • Vital fuel identified to decarbonise maritime transport
  • Practical and economical for long-range demands over li-batteries
  • Hydrogen addresses previous renewable energy limitations with a solution for storage and intermittency

How PEM fuel cells work

Similar to batteries, fuel cells operate with electrochemical reactions between the anode or cathode and the electrolyte membrane, but with continuous fuel and air supplies.

When hydrogen comes in contact with the catalyst, the hydrogen splits into protons and electrons. The protons pass through the proton exchange membrane unimpeded and proceed to the cathode side, while the electrons are blocked and forced to travel through an external circuit. As they travel along the external circuit, they provide the electricity needed for auxiliary power or to drive a motor. Eventually the hydrogen protons and electrons reunite and combine with oxygen to produce water.
