Abstract: An arrangement for storing thermal energy, which has a three-dimensionally configured heat accumulator is provided. The latter contains a solid natural material for heat storage. The heat-storage material is enclosed by a fluid-impermeable, flexible layer such that the heat-storage material is insulated at least in a pressure-tight manner with regard to the environment of the heat accumulator. A flexible cover layer is provided, which is coupled to the fluid-impermeable flexible layer such that the flexible cover layer applies a surface force to the fluid-impermeable flexible layer. As a result, the fluid-impermeable flexible layer is pressed areally onto the heat-storage material. The flexible cover layer (i) has the form of a mesh or (ii) is configured in the form of sheet-metal plates overlapping one another in an imbricated manner.

Abstract: A reactor device for the release of a gas from a starting material includes a reactor housing having a longitudinal axis and at least one single reactor arranged in the reactor housing, the single reactor including a base plate oriented transversely to the longitudinal axis, a starting material flow channel defining a starting material flow direction, a catalyst arranged in the starting material flow channel, a heating unit for heating the catalyst and/or the starting material and a gas collection chamber arranged above the starting material flow channel for collecting the gas released from the starting material.
