HYlight Cylinder

Optimised steel bottles for storage and transport of hydrogen.

Topic

Process establishment for homogeneous polymer-based internal coating of steel cylinders.

Project objective

(Green) hydrogen is an important energy source for creating a sustainable future and realising the energy transition in the form of renewable energies. However, this also requires regenerative, CO2-optimised hydrogen infrastructure concepts.

The research and development project represents an essential contribution to decentralised, non-transmission-bound hydrogen supply, in that the products to be developed pursue an innovative approach to the transport and storage of hydrogen.

The aim of the project is therefore to develop a material-minimised high-pressure steel container for the storage and transport of hydrogen. Based on current standard pressure levels of 300 bar, a container with the same wall thickness and material usage for 500 bar operating pressure is to be created. Compared to existing products on the market, the product to be developed can increase the pressure (and thus the amount of hydrogen stored) by up to 60 % or reduce the wall thickness and minimise the use of materials by 30 % to 50 %.

By means of the modular approach consisting of a high-strength steel cylinder and an organic/inorganic coating combination, container safety against hydrogen corrosion is not ensured by the increased wall thickness of the container, but a comparatively thin-walled container with a sufficiently hydrogen-impermeable barrier coating is developed.
