Definitions

  • the present invention relates to a hydrogen refueling station using a deformation zone to reduce pressure inside the hydrogen refueling station in case of an explosion.
  • HRS Hydrogen Refuelling Station
  • These demands can e.g. be complied with by minimising the amount e.g. iron used for the HRS enclosure.
  • This will also reduce the strength of the HRS enclosure, a strength which is needed for the HRS to comply with safety requirements and consequences of hydrogen leakage in the HRS such as an explosion inside the HRS enclosure.
  • Prior art deals with gas leakages e.g. by supplying a gas into the HRS enclosure to homogenize the gas herein and at the same time venting the gas out of the HRS enclosure.
  • prior art documents FR3001789 reduces the risk of an explosion followed by a gas leakage.
  • Prior art document FR2951217 describes a HRS enclosure provided with several holes which are used for venting in case of a gas leakage inside the HRS enclosure.

  • the horizontal panels define bottom and ceiling of the HRS enclosure.
  • substantially horizontal and vertical should be understood in a way which creates 90 degrees angles between the side panels (vertical panels) and between the side panels and bottom / ceiling panels (horizontal panels). Thereby the horizontal and vertical panels create a substantially rectangular HRS.
  • the at least one deformation zones is part of the enclosure of the dispenser module. No matter if the dispenser module is located a distance from the HRS center module or is an integrated part of the HRS center module it may also be provided with deformation zones as described throughout this description having the same functionalities and advantages as described in relation to the HRS center module.

  • the enclosure defines hazardous and non-hazardous zones.
  • the hazardous zone is preferably defined by the risk of occurrence of an explosion. Therefore the hazardous zone is often defined by a sub enclosure where hydrogen is treated.
  • Examples of treatment of hydrogen could be cooling, pressure control, filtering, flow control and the like. It should be mentioned that no electric components should be present in the hazardous zone to limit risk of ignition of leaked hydrogen.
  • the vertical panel comprising the deformation zone is the panel turning away from the location of the dispenser so that in case of an explosion, the dispenser and user hereof are protected in case of an explosion occurring in the HRS.
  • the deformation zones could be part of any of the vertical side panels and / or any of the horizontal bottom / ceiling panels.
  • the pressure resistance of the at least one deformation zone is P2 and the pressure resistance of the vertical and horizontal panels is P3 and wherein the pressure P3 is higher than the pressure P2.

  • the at least one deformation zone is implemented as a hatch connected to one of the panels by one or more hinges and / or one or more safeguards.
  • a hatch implementation of the deformation zone is advantageous in that predetermined area(s) of the panel can be opened by the pressure increasing pressure P2. This is due to the fact that the safeguard releasing the hatch at (or around) pressure P2. It is advantageous if the hinge is designed to comply with a higher pressure than P2 in that the hatch then stays connected to the HRS and is not blown away risking harming persons or material. Alternatively a hatch could simply be blown away however it is preferred that it remains connected to the HRS to avoid it damaging material or persons when it is landing again.
  • the deformation zones then facilitates a volume expansion of the hazardous zone in a predetermined direction i.e. the direction of the from the explosion center towards the panel comprising the hatch.
  • this direction is upward which is advantageous in that in the unlikely event on an explosion the blast ware is opening a deformation zone at the roof of the HRS thereby reducing the risk of anyone getting hurt.

  • the second part of the hatch is preferably the opposite side to the first side of the hatch.
  • the pressure P3 is between 0,1 bar and 0,5 bar.

  • the pressure P2 is less than the pressure P3, preferably between 0,9 bar and 0,3 bars.
  • the safeguards are designed to break at the pressure P2. This is preferred in that then the design of the safeguards is defining the pressure P2 at which the hatches should open.

  • the deformation zones 19 may be designed in several of different ways. According to an embodiment of the invention the deformation zones 19 could be designed as hatches 19 i.e. parts of a panel 17, 18 which is intended to deform e.g. blow away upon exposure of a blast wave. In an embodiment of the invention blow away could include open around a pair of hinges 27. Accordingly one part of such hinge 27 is attached to a panel 17, 18 by safeguards 24 which initiate the opening of the hatch 19 when exposed to a certain pressure P2 which is lower that the pressure P3 required to deforming or "opening" a panel 17, 18 (where such panel 17, 18 is not designed to be opened).
  • pressure P3 is preferably also the pressure at which service doors 26 are opened however service doors 26 could be designed to open closer to pressure P2 that e.g. joints of panels 17, 18. Accordingly it is preferred that the service doors 26 are built to withstand a higher pressure than the deformation zones 19.
  • the hatch 23 could pilotable mounted to a panel 17, 18. In this way the hatch 23 will open by turning around a center line of the hatch 23.

  • Figure 3 illustrates service doors 26 at each of the side panels 17a, 17b, 17c however this may not be necessary. Instead or in addition one or more of the illustrated service doors 26 may serve as deformation zones 19 or a combination of service door 26 and deformation zone 19 in the form of a hatch 23.
  • not all service doors 26 may be used as deformation zone 19. Especially it is not preferred to use a service door 26 in the front panel 17a as a deformation zone 191. This is because a risk then occurs that persons in front of the HRS 1 is struck by parts escaping the HRS in case of an explosion where a deformation zone 19 such as a service door 26 faces towards the person. Hence the service doors not used as deformation zones 19 should be built and locked to withstand pressure which is higher than deformation zones 19 e.g. implemented as service doors.

  • a safety wall 33 is located close to the service door 26 which when opening will be stopped by the safety wall 33 and thereby direct the pressure / parts from the HRS enclosure in a certain direction.
