A concentrated solar power storage system and method convert water into water vapor by the solar thermal energy, and the water vapor further operates a hydroelectric power generation system with a water storage (or an energy storage capsule) through a repeated conversion process.

An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000 C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

An energy storage system (TES) converts variable renewable electricity (VRE) to continuous heat at over 1000 C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. The delivered heat which may be used for processes including power generation and cogeneration. In one application, the TES provides higher-temperature heat through non-combustible fluid to an alumina calcination system used to remove impurities or volatile substances and/or to incur thermal decomposition to a desired product.

Disclosed is an air-compression energy-storage and power-supply system having air purification capability through using solar energy. The system includes: a solar energy power supply device, it utilizes solar energy to produce power for the system itself, and for users to use in daytime; an air purification device, with its exhaust fan connected to a transformer power distribution device to obtain the power for rotation, so that outside air flows into the air cylinder after filtering by the air filter, then the purified air is exited from the air cylinder to provide purified air; an air-compression energy-storage and power-supply device, used to compress the purified air into high pressure for storage, and the high pressure purified air is released at night, for the generator to produce power for user to use at night; and a wind power transmission device, disposed above the air purification device.

A mechanical power system provides torque without using a heat engine where fossil-fuel engines have conventionally been used, by replacing the fossil-fuel burning engine with a rotary pneumatic motor and feeding pressure-regulated compressed gas to the rotary pneumatic motor. The rotary pneumatic motor can be used anywhere, and requires preferably compressed nitrogen in a non-liquid state. Automotive, marine and electrical generating applications are adaptable, and auxiliary power is available for emergencies where a supply of compressed gas has been exhausted. A screw-type compressor can be electrically powered to supply compressed gas to the pneumatic motor where tanks of compressed gas have been exhausted. An electrical generating power plant includes an array of solar panels for generating direct current (DC) and a DC/AC converter for converting the DC to alternating current (AC) and outputting a portion of the AC via a power plant output port to supply an AC load.

A system for providing access to a wireless communication network can include a plurality of renewable energy structures. Each renewable energy structure can include an electricity generation assembly, a telescoping support pole positioned to support the electricity generation assembly, and a wireless communication device configured to relay wireless communication signals between a host signal source and a client device. The electricity generation assembly can include a wind turbine assembly and/or a solar power structure. The wireless communication device can include a cellular telephone signal repeater and/or wireless internet equipment. Each structure can include a display, such as an advertisement, one or more benches, and/or a container. Each structure can optionally include a water purification system, one or more cameras, one or more lights, and/or one or more motion or voice sensors for activating or deactivating various components of the system. Each structure may be permanently installed or mobile.

A power plant (1) has an energy converter (3) for converting heat energy to another form of energy with use of a working fluid, and a heat exchanger (4) for rejecting heat from working fluid. A secondary circuit (6) provides coolant to the heat exchanger (4). The secondary circuit (6) includes a heat store (7) arranged to store coolant, a secondary heat exchanger (8), a coolant diverter (12), and a controller configured to route coolant from the working fluid heat exchanger (4) to the heat store (7) in order to reject heat to the store, or to the secondary heat exchanger (8). It chooses between these according to which provides more effective heat rejection from the coolant, and possible other factors. Typically, the controller uses the heat store during daytime and the secondary heat exchanger during night time. This means that heat working fluid is rejecting heat during day time at a temperature of the night time, thereby achieving improved plant efficiency.
