  • Patent number: 11879594
    Abstract: A method for manufacturing tanks for storing or containing a fluid under pressure and a method for manufacturing pipes for containing or channeling a fluid under pressure, such as for storing, containing or channeling hydrogen, natural gas or a hydraulic fluid. The method is less complex than known procedures, can be employed in a continuous or semi-continuous manner and allows for a lower thickness of the shell made from the fibres. The method comprising providing a liner having a cylindrical portion with two ends and two dome portions at the respective ends of the cylindrical portions or a liner having a cylindrical portion and one or two open ends; fabricating a tube of fibre filaments by means of the pullwinding method; and wrapping the tube of fibre filaments onto the liner such that at least the cylindrical portion of the liner is enclosed by the tube of fibre filaments.

  • Patent number: 11845659
    Abstract: The present invention relates to a composite material for hydrogen storage based on metal hydrides and to a method of operating a hydrogen storage system based on metal hydrides capable of releasing and absorbing hydrogen. Such hydrogen storage systems based on metal hydrides may be applicable as a fuel source for a fuel cell. The composite material for hydrogen storage comprises a powder or pellets of a hydride and a phase changing material (PCM), wherein the PCM is an encapsulated phase changing material (EPCM) which is homogeneously dispersed within the powder or pellets of the hydride.
