Abstract
Abstract This invention relates to a storage element for a sorption heat storage system comprising a hermetically sealed tubular vessel having a length which is a multiple of its cross section containing a sorbate. The vessel is divided into two regions by an interspace. A first region contains a solid sorption medium and a second region contains an accumulator to collect condense and hold back sorbate driven out of the sorption medium. The invention also relates to a heat storage system consisting of a tank, a plurality of heat storage elements arranged in a parallel array with their interspaces in a plane, a means to divide the tank into two regions outside the elements, lying in the plane of the interspaces and at least one heat transfer media contained in the tank outside the storage elements.
