Definitions

  • the present invention relates to a method for transporting hydrogen through a natural gas line.
  • the hydrogen can be prepared in known manner, e.g. from water by electrolysis, the DC power required for the electrolysis being environmentally friendly, e.g. can be provided by solar power plants or wind turbines or tidal power plants.
  • the recovered hydrogen can react in a controlled manner with the oxygen of the ambient air to form water vapor, wherein the hydrogen emits electrons in this reaction, so that a current can be provided for the supply of any electrical load by this reaction.
  • the resulting waste heat can be used very efficiently in terms of combined heat and power.
  • Hydrogen as a fuel or energy source can be used in particular for the supply of buildings, such as households or offices, for this purpose, fuel cells are provided in the building or in the vicinity of the building, the supplied hydrogen for power generation for energizing electrical consumers, such as for example, use an electrically powered device, the respective building.
  • fuel cells are provided in the building or in the vicinity of the building, the supplied hydrogen for power generation for energizing electrical consumers, such as for example, use an electrically powered device, the respective building.
  • familiar solutions are usually resorting to existing natural gas networks or natural gas networks, in which case the hydrogen is admixed with the natural gas to be transported via the natural gas pipeline, so that the hydrogen together with the natural gas is transported via the gas pipeline to the building to be supplied.
  • the proportion of hydrogen in the total transported gas mixture is up to about 10 vol .-%. A higher concentration of hydrogen is usually difficult or impossible to achieve.
  • the present invention has for its object to provide a method for transporting hydrogen through a natural gas line, which is improved over known such methods.
  • the process according to the invention can provide a substantial improvement, in particular by avoiding
  • the hydrogen can be passed in nearly pure form through the hydrogen conduit.
  • the natural gas line can be made suitable for transport with hydrogen in almost pure form. It can therefore be dispensed with in the known method admixing of the hydrogen to the natural gas, which makes an acceptable transport only possible in known methods, since by the transport of hydrogen in this mixture too strong a permeation of very small hydrogen molecules through the wall of the Natural gas pipeline can be avoided.
  • the inventive method for the supply of a building allows the direct use of fuel cells, preferably low-temperature fuel cells, which may have an operating temperature of preferably 80 ° C to 120 ° C and a maximum of 180 ° C. It is not necessary to separate or extract the hydrogen from the hydrogen / natural gas mixture transported via the natural gas line in the case of known solutions and to do so in a very costly and expensive manner. Even a so-called reforming is not required.
  • the hydrogen has a purity within a range of 80 to 99.999 vol.%, Or within a range of 97 to 99.99 vol.%, Or within a range of 97.5 to 99, 9 vol .-% is.

  • Portions of the hydrogen line to be connected to each other can advantageously be easily connected by means of fittings and sliding sleeves.
  • Fittinge and sliding sleeves can be made of brass or brass alloys or polymer material.
  • a hydrogen line is used, which consists at least partially of PE-X (cross-linked polyethylene).
  • a PE-X existing hydrogen pipe is particularly temperature resistant and mechanically resistant, so that the introduction of the hydrogen line in the natural gas line can be carried out particularly easily, in addition, such Hydrogen line withstands higher temperatures, which can occur, for example, in industrial plants.
  • a hydrogen line is particularly preferred, which consists of PE-X or PE-X, which is radically crosslinked, in particular a hydrogen line, which consists of PE-Xa (peroxide crosslinked PE) or contains PE-Xa, can be advantageously used ,
  • a hydrogen line is used, the inside of which is provided with a hydrogen barrier layer.
  • a hydrogen barrier layer on the inside of the hydrogen line, ie on the side facing the lumen of the hydrogen line, advantageously increases the diffusion-tightness of the hydrogen line, so that the permeation and thus the loss of hydrogen from the hydrogen line is reduced.
  • the hydrogen barrier layer on the outside of the hydrogen line, ie on the side facing away from the lumen of the hydrogen line. It is also possible that both the inner sides, as well as the outside of the hydrogen line has a hydrogen barrier layer.

  • Another hydrogen barrier is polyvinyl alcohol (EVAL, EVOH).
  • the present invention also most preferably comprises a hydrogen conduit formed in the form of a multilayer conduit consisting of at least two interconnected layers.
  • At least one layer consists at least partially of polyolefin.
  • a layer structure of the pipeline in which at least one layer consists at least partly of polyolefin has the advantage that this layer can be produced favorably in a plastic molding process, for example an extrusion process.
  • a hydrogen line comprises a metal layer, which is designed in particular very thin.
  • a metal layer for example of aluminum or another metal, a thickness of 1 to 50 pm, more preferably a thickness of 5 to 30 ⁇ have.
  • MKV tube metal-plastic tube
  • Such an MKV pipe can be integrated into an existing natural gas tion be inserted or introduced in the everting process in the natural gas line, because the thin metal layer tolerates the bending stress occurring during the Stülp compiler without damage.
  • such a hydrogen pipe network can be built from an existing natural gas network, without significant civil engineering work, trenching or earth movements are necessary. Only at a few selected locations, for example at junctions, are construction pits to be made.
