Arrangement and Method for Storing Energy in Buildings and Supplying Energy to Buildings

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

This invention provides a complete system and method for storing and supplying energy in buildings by using renewable electricity (such as from solar panels) to produce hydrogen from water via electrolysis. The hydrogen is chemically stored by reacting it with special aromatic compounds (like N-ethylcarbazole), and later released for use in a fuel cell to generate electricity and heat when needed. The system is designed for safe, medium- to long-term energy storage without the risks of high-pressure hydrogen tanks, and can make buildings more energy-independent and flexible in use of renewable power.

Use CasesContent extracted from patent full text and abstract with AI.

• Storing excess solar or wind energy in residential homes for later use.
• Enabling off-grid or nearly autonomous operation of standalone buildings such as private houses, vacation homes, or commercial/industrial properties.
• Replacing conventional oil heating systems by reusing existing fuel tanks for chemical energy storage.
• Providing both power (electricity) and heating/cooling for buildings with fluctuating renewable supply.
• Helping to stabilize power grids by absorbing excess electricity and releasing it during periods of high demand.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows safe, lossless storage of renewable electricity for days to weeks (beyond what batteries offer).
• Reduces or eliminates reliance on fossil fuels by making buildings self-sufficient with renewables.
• Improves hydrogen safety compared to traditional pressure storage methods by using chemical carriers.
• Utilizes existing infrastructure (like oil tanks), lowering installation costs.
• Provides combined heat and power (CHP), improving energy efficiency by using both electricity and waste heat.
• Can participate in energy markets, allowing users to store energy when it’s cheap and use or sell it when prices are high.

Patent Abstract

The present application relates to an arrangement for supplying energy to buildings, comprising at least one external connection for providing an electrical current, at least one electrolyser (2) for producing hydrogen from water using the electrical current from the connection (9), at least one first chemical reactor (3) for at least partially hydrating at least one substrate with an extended pi-conjugated system using the hydrogen formed in the electrolyser (2), at least one storage tank (4) for storing the substrate which is at least partially hydrated in the first chemical reactor (3), at least one second chemical reactor (5) for at least partially dehydrating the at least partially hydrated substrate produced in the first chemical reactor (3) and stored in the storage tank (4) releasing hydrogen, and at least one fuel cell (6) for oxidating the hydrogen released in the second chemical reactor (4) so as to release energy. The present invention likewise relates to a method for supplying energy using this arrangement, wherein the energy is used for heating or cooling the building. In the case where the building does not have a requirement for either heat or cold, a thermal store can be added. The financial gain is achieved as a result of the thermal store and the storage of electrical current.
