摘要： Systems and methods for energy storage and energy recovery are provided. An electrical-to-electrical energy storage system includes a thermochemical energy storage device, a blower, a compressor, a turbine, and an electrical generator. The TCES device includes a vessel, a porous bed, and a heater. The porous bed is disposed within an interior volume of the vessel. The porous bed comprises a reactive material. The reactive material is configured to release oxygen upon being heated to a reduction temperature, and generate heat when exposed to oxygen. The heater is in thermal contact with the reactive material. The blower is configured to remove oxygen from the interior volume. The compressor is configured to flow oxygen into the interior volume. The turbine is configured to receive a heated, oxygen-depleted gas from the interior volume. The generator is configured to be powered by the turbine to generate electricity.

摘要： A pumped heat storage apparatus has a prime mover, a power take off, first and second fluid working machines functioning as a compressor (8) and as an expander (10), a working fluid circulation pathway with high and low pressure sides, and high and low temperature heat exchangers (18A-B). The heat exchangers operate using direct contact between gaseous working fluid and solid thermal storage media, such as glass beads, which move in opposite directions, typically using an augur (44). The system is reversible between energy storage and energy recovery modes and when it reverses, the direction of movement of the working fluid and the thermal storage media reverses. The apparatus may very rapidly swap between energy storage and energy recovery while having a high capacity and energy throughout.

摘要： The present disclosure is directed to materials that can be used in a heat storage and transfer, and an improved method for storing thermal energy which includes a high heat capacity thermal energy storage system using pumped or flowing metallic phase change materials (MPCs). Heat is added by pumping a cold fluid of MPCs mixed with a fluid media such as a molten glass and/or salt from a tank through a heat exchanger, solar receiver, or electrical heater cell and returning the heated fluid to a tank, or solid MPCs can be transported physically, or via gas transport such as entrained flow or a circulating fluid bed. In the heat exchanger, heat can optionally be transferred directly to a counterflowing gas or other fluid, or indirectly through heat exchanger walls to a working fluid, which can be steam, CO2 or sCO2, He, H2, process gas, and/or heat transfer fluid. The MPCs (encapsulated MPCs, non-coated MPCs) are solid-liquid and/or solid-solid phase change particles, salts, metals, or other compounds with a melting point between the hot and cold fluid temperatures, and can optionally include high heat capacity, and/or energy absorbing (IR and divisible) nanoparticles.

摘要： A thermal energy storage device comprises a tank and container. The container has an obverse wall, a reverse wall and an internal space. The internal space of the container contains a phase change material, and wherein the obverse wall and/or reverse wall of the container has a substantially planar surface, wherein the substantially planar surface extends from a cross-sectional centre of the container to internal wall of the internal space of the tank. The container is arranged in the internal space of the tank to define a flow path for a fluid in the internal space of the tank, the flow path allows a fluid to flow from opening of the tank partially over a surface of the obverse wall of the container and then partially over a surface of the reverse wall of the container.

摘要： In one aspect, the disclosure relates to an oxide-molten salt (OMS) composite material offering excellent energy storage capacity at low cost. The OMS composite material can be provided in at least three forms, including a porous, perovskite-oxide particle as a matrix having pores filled with unary salt or salt mixtures; an external shell of perovskite-oxide particles and an internal core of salt or a salt mixture; and/or a porous, perovskite-oxide particle as a matrix filled with unary salt or salt mixtures, wherein the whole particle is enclosed with an oxide outer shell. Further in this aspect, the outer shell can be dense but either mixed ionic-electronically conductive or porous. In another aspect, the disclosed methods and systems can be used for grid-scale energy storage by retrofitting existing steam turbine-based power plants and concentrated solar plants. In a further aspect, the disclosed methods, systems, and materials are environmentally benign.

摘要： The heater block of the present disclosure can transfer heat from a heat transfer fluid to a received fuel fluid, air passing in proximity to the heater block or combinations thereof. These heat transfers reduce, substantially prevent or prevent the freezing of water within the received fuel fluid and/or the air as it enters an intake member of a gas burning unit.
