Pressure Vessels

EMS uses its expertise on filament wet winding to manufacture high-strength lightweight pressure vessels.

We believe that vehicles in the near future will no longer rely on fossil fuels. Instead, hydrogen (H2) will be an important part of the energy mix, not only for cars but for buses, trains and HGVs. Our team has developed H2 vessels for this purpose from high-strength, lightweight carbon fibre reinforced plastics (CFRP).

Industry sectors

We create pressure vessels for use in both stationary and mobile applications, covering:

  • Hydrogen infrastructure solutions (storage and filling stations)
  • Hydrogen transportation for re-fuelling
  • Hydrogen powered rail vehicles
  • Hydrogen powered buses, trucks and other vehicles
  • Hydrogen powered cars

Type 4 Pressure Vessels

Our composite (CFRP) pressure vessels are Type 4 and offer significant advantages over other pressure vessels.

  • The carbon fibre-reinforced structure creates a superior strength/stiffness to weight ratio, resulting in a potential 450kg weight reduction of gas containment systems in buses and trucks
  • This leads to vastly improved fuel economy, underlining the economic argument for hydrogen fuelling
  • It also expands the range of vehicles and situations in which these vessels can be used

Other advantages of using CFRP pressure vessels are that they are durable and offer chemical resistance, X-ray translucency and no thermal expansion.

How EMS manufactures high strength pressure vessels

We create high strength lightweight pressure vessels using filament wet winding, with braiding and resin transfer moulding used for more complex geometries. Our CFRP Type 4 pressure vessels can be used for up to 30 years without needing to be replaced, which is twice the expected life span of Type 1 and Type 2 vessels.

  • Our Type 4 pressure vessels have a nominal working pressure of 350 bar, 500 bar and 700 bar
  • The 500 bar pressure vessels offer a usable H2 capacity of 6.2kg
  • The 350 bar and 700 bar devices can be supplied in various dimensions

Mobile Hydrogen Tanks

Included in our range of high-strength, lightweight composite (CFRP) pressure vessels are our mobile H2 tanks, which have been developed for cars and other individual transportation.

These have a nominal working pressure of 700 bar and meet both EC 79-2009 and Global Technical Regulations.
