Arrangement, useful for supplying energy to buildings such as solitary buildings, comprises an energy-generating installation e.g. photovoltaic installation, electrolyzer, first chemical reactor for hydrating substrate, and storage tank

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes an integrated energy supply system for buildings, particularly standalone buildings, combining solar power generation, hydrogen production through electrolysis, chemical hydrogen storage in special substrates, and energy release on demand through fuel cells. Solar panels generate electricity, which powers an electrolyzer to produce hydrogen from water. The hydrogen partially saturates a special substrate, which is stored and later used to generate electricity via a fuel cell, thus providing a stable and on-demand energy supply.

Patent Abstract

The arrangement comprises an energy-generating installation such as a photovoltaic installation for providing an electrical current, an electrolyzer (2) for producing hydrogen from water using the electrical current from the energy-generating installation, a first chemical reactor (3) for partially hydrating a substrate with an extended pi -conjugated system using the hydrogen formed in the electrolyzer, a storage tank (4) for storing the substrate hydrated partially in the first chemical reactor, and a second chemical reactor (5) for partially dehydrating the partially hydrated substrate. The arrangement comprises an energy-generating installation such as a photovoltaic installation for providing an electrical current, an electrolyzer (2) for producing hydrogen from water using the electrical current from the energy-generating installation, a first chemical reactor (3) for partially hydrating a substrate with an extended pi -conjugated system using the hydrogen formed in the electrolyzer, a storage tank (4) for storing the substrate hydrated partially in the first chemical reactor, a second chemical reactor (5) for partially dehydrating the partially hydrated substrate, which is produced in the first chemical reactor and stored in the storage tank, and a fuel cell (6) arranged in the second chemical reactor for the oxidation of the hydrogen under release of energy. The electrolyzer is connected with the fuel cell through the first reactor, the storage tank and the second chemical reactor. The substrate is partially hydrogenated in the first reactor at a temperature of 50-180[deg] C and a pressure of 2-200 bar in the presence of a catalyst. The fuel cell is a low temperature polymer electrolyte membrane fuel cell, and the electrolyzer has a reverse-driven low-temperature polymer electrolyte membrane fuel cell. A water retention medium is arranged in the electrolyzer.
