Definitions

  • the present invention relates to hydrogen storage, supply and compression systems which use metal hydride (MH) materials.
  • MH metal hydride
  • the invention relates to composition, layout and method of the forming of the content of a metal hydride container, or a metal hydride bed, as well as method of making the metal hydride container.
  • Metal hydrides provide efficient hydrogen storage for various applications, when system weight is not a critical issue. Due to very high volumetric density of atomic hydrogen accommodated in the crystal structure of the MH metal matrix, hydrogen storage in MH is very compact. At ambient temperatures the equilibrium of the reversible interaction of MH material with hydrogen gas can often take place at modest, ⁇ 1 -10 bar hydrogen pressures. Thus, hydrogen storage using MH is intrinsically safe and benefits from avoiding use of potentially unsafe compressed hydrogen gas and energy inefficient liquid H2. Endothermic dehydrogenation decreases temperature of the MH leading to decreased rates of hydrogen evolution. This, in turn, is an intrinsic safety feature of use of the MH, allowing to avoid accidents even in case of rupture of the hydrogen storage containment. The use of MH also allows to implement simple, efficient and safe technology of thermally-driven hydrogen compression characterised by absence of moving parts and possibility to use waste heat instead of electricity for the hydrogen compression.
  • the hydride container according to these solutions comprises a high-pressure containment filled with the hydride material (as a rule, in a powder form) and comprising heat distributing means.
  • the heat distributing means preferably, a plurality of transversal heat-conductive fins
  • the role of the metal hydride bed which has to have high enough effective thermal conductivity, is in providing fast transfer of the heat generated / absorbed in the MH during hydrogen absorption / desorption to / from cooling / heating accessories.
  • a simple and efficient method of the forming the MH bed is in the compacting of the MH powder and a heat-conductive material, including expanded natural graphite, ENG 7 .
  • Recompressed ENG combines two important properties, (i) high plasticity under compression loads and (ii) high thermal conductivity and gas permeability in the direction perpendicular to the direction of the compacting.
  • Further improvement of heat transfer in MH / ENG compacts was suggested by De Rango et. al 8 as their alternative arrangement with heat conductive fins in an MH hydrogen storage tank. As a rule, this layout is applied for quite stable MH's (e.g., MgH2) which are taken for the compacting with ENG in the hydrogenated state.
  • Patent application US 2010/0326992 Al must be used in "hybrid" hydrogen storage systems and hydrogen compressors utilising MH), making the MH / ENG compacts is possible either from the non- hydrogenated hydride forming materials, or from their hydrides stabilised, for example, by an exposure in carbon monoxide or sulphur dioxide 9 .
  • disintegration of the formed compacts during hydrogenation is highly possible due to a significant volume increase of the MH filler.
  • the latter approach requires the usage of highly toxic gases for the MH stabilisation.
  • a metal hydride bed disposed in a metal hydride container includes:
  • the gas-tight containment may be made as a cylinder with two end caps, one of which is equipped with a hydrogen input / output pipeline.
  • the heat conductive fins may be perforated; they may be disposed inside the containment transversally, and uniformly distributed along the cylinder axis in the mixture of the hydride forming material with the binder.
  • the hydride forming material may include ABs-type intermetallide.
  • the hydride forming material may include AB2-type intermetallide and / or BCC solid solution alloy.
  • the hydride forming material may additionally comprise the ABs-type intermetallide in the amount of 10% as respect to the total weight of the hydride forming material.
  • the binder may be expanded natural graphite.
  • the ratio of weight of the hydride forming material to its total volume in the metal hydride bed may vary from 0.50 to 0.60 of the real density of the hydride forming material in the hydrogenated state.
  • the mixture may be taken as a loose powder where the expanded natural graphite is taken in the amount from 1 to 2% as respect to the weight of the hydride forming material.
  • the hydrogen input - output pipeline may be connected with a tubular filter longitudinally disposed in the metal hydride bed.
  • the mixture may be taken as a compact where the expanded natural graphite is taken in the amount from 15 to 20% as respect to the weight of the hydride forming material.
  • the compact may have an axial hole throughout the length of the metal hydride bed, the hydrogen input - output pipeline may be equipped with an in-line gas filter, and the axial hole may additionally comprise a porous member.
  • the forming of the metal hydride bed when the mixture is taken as the loose powder may include the following steps:
  • the forming of the metal hydride bed may include the following steps:
  • the compacting pressure for making one pellet may be from 150 to 250 MPa.
  • the mass of the mixture taken for the compacting of one pellet at the specified compacting pressure may be selected to provide the thickness of the pellet between 10 and 15 mm.
  • the loose powder from the second portion of the mixture may be divided by small portions whose number is equal to the number of the compacted pellets plus one.
  • the last portion of the loose powder may be added.
  • the pressure of the final compacting of the metal hydride bed in this case may be from 50 to 60 MPa.
  • the making of the metal hydride container may include the following steps: (a) . of installing the end cap with the hydrogen input / output pipeline;
  • FIG. 1 Metal hydride bed according to the first embodiment of the invention
  • FIG. 3 Drawing of a metal hydride container with the metal hydride bed according to the first embodiment of the invention (Example 1 );
  • FIG 4 Drawing of a metal hydride container with the metal hydride bed according to the second embodiment of the invention (Example 2);
  • metal hydride container comprising the metal hydride bed in accordance to the invention is shown.
  • the container and the bed include the following components, as indicated by the corresponding reference numerals in Figures 1 to 5:
  • a metal hydride container comprises a metal hydride bed disposed in a gas-tight containment (21 -23) which is preferably made as a cylinder (21 ) with end caps (22, 23), one of which (22) is equipped with a hydrogen input / output pipeline (24).
  • the metal hydride bed is formed by a mixture (10, 1 1 ) of a powdered hydride forming material and a binder.
  • the scope of this invention is related to metal hydride materials which form "unstable" hydrides, i.e. equilibrium of their interaction with gaseous hydrogen takes place at a pressure higher than the atmospheric pressure at the ambient temperature.
  • the hydride forming material may include ABs-type intermetallide, for example, (La,Ce)Nis.
  • the hydride forming material may include AB2-type intermetallide (e.g., (Ti,Zr)(Cr,Mn,Fe,Ni)2) and / or BCC solid solution alloy (e.g., on the basis of V).
  • the materials belonging to the second group are characterised by higher sensitivity towards "poisoning" with gas impurities in hydrogen (e.g., oxygen and water vapours) and less easy activation than the ABs-type intermetallides possessing a strong catalytic effect in hydrogen transfer reaction, it is beneficial to take the materials based on the AB2-type and / or BCC alloys in form of mixture with an additive of the ABs-type alloy.
  • the amount of the additive sufficient for the improvement of the activation performances and the "poisoning" tolerance is about 10 wt% as respect to the total weight of the hydride forming material.
  • the mixture (10, 1 1 ) also includes a binder which combines high thermal conductivity, plasticity and high porosity under hydrostatic pressure.
  • the best material possessing the required combination of these properties is expanded natural graphite (ENG).
  • the second component of the metal hydride bed is a plurality of heat conductive fins (12) which are disposed in the inner space of the containment (21 -23) filled with the mixture (10, 1 1 ) and have a firm thermal contact with the inner surface of the containment, e.g., its cylindrical part (21 ).
  • Such a layout foresees that the cooling of the MH bed for removal the heat released during exothermic H2 absorption, and the heating of the MH bed for supply of the heat to provide endothermic H2 desorption is carried out from the external surface of the containment.
  • the forming of the metal hydride bed according to the invention is carried out by filling the inner space of the containment (cylindrical part 21 with installed (e.g. welded) end cap 22) with the mixture (10, 1 1 ), as well as the installation of the fins 12. This procedure is carried out from the side of the opposite end cap (23) which is installed (e.g. welded) after the forming of the metal hydride bed.
  • the amount of metal hydride material loaded in the container according to the invention corresponds to the filling fraction from 0.50 to 0.60 of the real density of the hydride forming material in the hydrogenated state.
  • Exceeding the upper limit is detrimental for the containment which could be deformed or broken due to expansion of the MH material during hydrogenation.
  • Lowering the filling fraction below the lower limit will result in the decrease of hydrogen storage capacity of the metal hydride container, as well as in the lowering the effective heat conductivity of the MH bed.
  • conventional solutions use the lower filling fractions to avoid local compaction of the MH material above the upper safety limit in the bottom part of the containment. Usage of the additive of ENG within this invention allows to mitigate this problem.
  • Figure 1 shows the metal hydride bed according to the first embodiment of the invention when the mixture of the metal hydride material and the binder is taken as a loose powder.

  • heat conductive fins (12) are uniformly installed (pressed) inside the containment to provide firm thermal contact with its inner surface.
  • Such arrangement provides uniform temperature distribution within metal hydride bed during exothermic hydrogen charge and endothermic hydrogen discharge processes. In so doing, the rate of the corresponding heat removal and heat supply to / from MH will be limited by the rate of external cooling / heating the containment rather than by the internal thermal resistance of its content.
  • the end cap 22 is equipped with a hydrogen input / output pipeline (24) connected from its opposite side to a tubular gas filter (25) providing uniform distribution of hydrogen in the metal hydride bed and protecting gas manifolds connected to the pipeline 24 from their contamination with fine powder of the mixture (10).
  • the fins 12 may be perforated as shown in side view A.
  • the central hole in the fin provides the axial filter 25 to penetrate throughout the length of the metal hydride bed while the periphery holes facilitate the loading of the powdered mixture 10 in the containment.
  • the loading is carried out from the side opposite to the end cap 22 carrying the assembly of the hydrogen input - output pipeline 24 and filter 25. After the loading, the end cap 23 is installed (e.g. welded).
  • the amount of the ENG additive within this embodiment is quite low, 1 to 2 wt.%, due to very low density (below 0.1 g/cm 3 ) its volume fraction in the loose powder mixture will be quite high, approximately, 30 to 60%.
  • the voids between the MH particles in the mixture will be filled with ENG.
  • the MH particles increase their volume, and stresses compacting the mixture appear.
  • the stresses will be absorbed by it thus lowering stresses in the wall of the containment.

In doing so, the mass of the portion of the loose powder 10 loaded in between the pellets 1 1 should be approximately equal to the mass of the pellet.
  • the first and the last portions of the mixture loaded in the containment should be taken in the form of the loose powder 10.
  • the compacted metal hydride bed has a good uniformity and remains stable during cyclic hydrogen absorption / desorption. Further decrease of the portion of loose powder 10, or mass of one pellet 1 1 corresponding to the thickness of the pellet below 10 mm at the compacting conditions is related to too high labour efforts for the making the metal hydride bed and does not makes sense from the economic point of view.
  • the increase of amount of the ENG above 20 wt.%, compacting pressure for making one pellet above 250 MPa, as well as the post-compacting pressure above 60 MPa will result in the decrease of porosity of the mixture (10, 1 1 ) and, in turn, slowing hydrogen charge / discharge processes down due to mass transfer limitations.
  • the increase of the post-compacting pressure above 60 MPa can result in the damage of the gas-tight containment (21 , 22).
  • the swelling of the metal hydride material results in further compacting of the portions of the mixture 10 taken as a loose powder thus avoiding too high stresses in the wall of the containment 21 .
  • the compacting force generated during hydrogenation assists in the formation of the uniformly compacted metal hydride bed as a whole that provides very good effective thermal conductivity and, in turn, fast dynamics of hydrogen charge and discharge.

  • 0.5 mm thick copper fins (12) are pressed in the containment.
  • the fins 12 are perforated (see Figure 3B), so as the central hole, 8 mm in diameter, provides insertion of the filter 25, and the periphery holes facilitate the filling of the container with the powder (10) of MH material mixed with ENG binder.
  • the assembling of the metal hydride container which includes the forming of metal hydride bed is carried in the following sequence:
  • the filling density of the MH material (total weight 3.2 kg) in the container (0.98 L in the void inner volume) is equal to 3.27 kg/L, or 55.5% of the density of the MH material in the hydrogenated state (the value calculated from XRD data for the AB2- and ABs-hydrides is about 5.89 kg/L).
  • the MH material absorbs 550 NL H2 that corresponds to the hydrogen storage capacity of 172 NL/kg.
  • About 500 NL H2, or 90% of the stored hydrogen, can be released at the discharge pressure of 2 bar (absolute) and H2 output flow rate above 7.5 NL/min (or 2.34 NL/min per 1 kg of the hydrogen storage material) when the MH container is heated by an ambient air (To 20 °C), flow velocity about 3 m/s.
