  • On board hydrogen storage


For lower power requirements, pressurized storage is likely to be the best solution. We will supply the hydrogen storage container(s), connection and safety distribution blocks, gas control blocks, double block and bleed valve blocks, valves, instrumentation and pipe lines. We can also design and supply double walled pipes for use in gas safe machinery spaces (fuel cell spaces).

It is paramount that our system design corresponds to your specific wishes, the requirements of the IMO Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF) and the regulations of the classification society of your choice. The IGF and class regulations for pressurized hydrogen storage do not yet fully accommodate this new technology. However, we can provide solid advice as we have been involved in several hydrogen research projects and have developed our own LNG fuel systems.

A pressurized H2 fuel system contains the following elements:

  • 10 tot 45ft Hydrogen storage container(s) with 300, 350 of 500 bar pressure
  • Light weight type 4 hydrogen storage cylinders
  • Connection- and safety supply blocks
  • Gas regulating blocks
  • Double block and bleed valve blocks
  • High- and low pressure hydrogen pipe lines
  • Vent and drain pipe lines
  • Vent mast
  • Cooling water pipe lines
  • Double walled pipe lines in gas safe machinery spaces
  • ESD system
  • Alarm monitoring and process control system


For greater power requirements, designing a system with cryogenic storage is an option. In such a system, a type C tank stores the hydrogen and a pressure build up heat exchanger maintains the tank at the desired pressure. Feeding hydrogen to the consumers reduces the pressure in the tank. A gas heater (shell and tube heat exchanger) heats the hydrogen gas to the correct temperature before it passes to the fuel cell. Insofar as possible, all the equipment, valves and instrumentation are assembled in a gastight tank connection space (TCS) which is then welded to the tank.
