Plant for the Generation of Hot Water and/or Steam and for the Storage of Water in Liquid and/or Gaseous Form for Use in a Gas Turbine Power Plant

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

The patent describes a system and method for generating hot water and/or steam, and for storing water in liquid and/or gaseous form, for use in a gas turbine power plant. The system incorporates one or more storage tanks for water that is heated using energy from at least one external energy source (such as surplus electricity, renewable energy, or waste heat), which can be located outside the power plant itself. The hot water or steam produced is injected into the gas turbine’s working fluid stream to increase the plant’s efficiency and flexibility, particularly during demand peaks or rapid startup.

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

• Peak load management and rapid response power generation in gas turbine plants.
• Integration with renewable energy sources for storing excess electricity as thermal energy.
• Combined heat and power (CHP) plants to maximize fuel utilization.
• Industrial gas turbine plants requiring fast operational flexibility.
• Energy storage solutions for grids with high penetration of intermittent renewables.

BenefitsContent extracted from patent full text and abstract with AI.

• Enhances the efficiency and output of gas turbine power plants by utilizing excess or renewable energy to generate and store steam/hot water for peak times.
• Allows decoupling of energy input and energy output, enabling flexible, on-demand energy release.
• Improves grid stability by providing a means to store excess renewable energy and release it quickly as electricity or heat.
• Reduces reliance on fossil fuels by optimizing heat usage and integrating renewables.
• Enables rapid startup and load changes for gas turbines, supporting grid balancing and ancillary services.
• Reduces fuel consumption and emissions by increasing the overall efficiency of the thermal process.

Patent Abstract

The invention relates to a system and a method for producing hot water and/or steam and for storing water in liquid and/or gaseous form for use for a gas turbine power plant (1) having a compressor (1.2) and a turbine (1.5), using a system (2) for producing hot water and/or steam that comprises at least one storage system having at least one storage container (2.1, 2.2) for storing the water, in which storage container the water is heated by supplying energy, wherein the energy is provided from at least one external energy source that is arranged outside the gas turbine power plant (1) and/or the system (2), and wherein the hot water and/or the steam is used for injecting into a fluid flow between the compressor and the turbine and/or into the turbine (1.5) of the gas turbine power plant, and wherein according to the method the hot water and/or the steam is injected into a fluid flow between the compressor (1.2) and the turbine (1.5) and/or into the turbine (1.5) of the gas turbine power plant (1) in an open process. The supplied energy for heating the water is advantageously provided from negative reserve power or excess electricity.
