Context

The effort and investments in developing green hydrogen (H2) technologies are continually increasing. However, a key component of the green hydrogen economy, which still poses a challenge, is providing safe and cost-effective large-scale storage and transportation (S&T) to ensure the economic competitiveness of green hydrogen. Currently, according to the state of hydrogen, there are different alternatives for its storage and transportation.

In this context, ONTZHi aims to address the following challenges:

  • Enhance the resistance of tank and pipeline materials.
  • Reduce the weight of the storage and transportation system.
  • Increase the safety margin of storage and transportation systems.
  • Decrease the cost and enhance the sustainability of storage and transportation.
  • Research and generate knowledge about the limits of metallic materials in interaction with hydrogen.

OBJECTIVES AND ACTIVITIES:

The ONTZHi project aims to increase knowledge in the field of H2 interaction with materials used in S&T systems and to design material protection systems against hydrogen to prevent degradation phenomena in metals and composites materials. Additionally, the project will develop new materials and more sustainable processes for tanks of light vehicles..

At the end of the project, ONTZHi will have developed 2 laboratory-scale demonstrators:

  • 1_ An H2 barrier coating demonstrator.
  • 2_ A recyclable composite tank demonstrator.
    In addition, at least one computational model will also be developed and used to define and develop simplified characterisation methods.

In order to achieve the aforementioned objectives, four work lines have been established. In each of them, the following elements will be explored, which are briefly summarized below:

1

METAL TANKS AND COMPONENTS

  • Metallic and ceramic coatings
  • Multilayer hybrid coatings
  • Carbon-based coatings.

2

TANKS FOR LIGHT VEHICLES.

  • Acrylic resin liners
  • Unidirectional Tapes
  • Polyamide Liner.
  • Taping Processes.
  • Sol Gel Coatings.
  • Metallic coatings.

3

DISTRIBUTION PIPELINES

  • 2 gas testing.
  • In-situ characterisation.
  • Ex-situ characterisation.
  • Coatings and application methods.

4

CHARACTERISATION AND MODELLING

  • Modelling and computation.
  • R&D H2 Gas characterisation.
  • Quantum modelling and computation.
  • R&D in liquid H2 characterisation.

Impacts

Each project workstream is expected to have the following impacts:

Metal tanks and components

  • Reduction of wall thickness and tank weight.
  • Improvement in mechanical strength and wear resistance of metal components.

TANKS FOR LIGHT VEHICLES.

  • Recyclable and low hydrogen permeation tanks for light vehicles.
  • Reduction of the storage system cost.
  • Increase in the efficiency, safety and sustainability of the tanks.

Distribution pipelines

  • Reduction of the embrittlement risk in existing pipelines.
  • Integrated solution for new pipelines with low embrittlement risk.

Characterisation and modelling

  • Simplified characterisation without the need of extreme pressure.
  • Software to predict material degradation.
