摘要： 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.

摘要： The power system comprises a working fluid circuit having a high pressure side and a low pressure side and configured to flow a working fluid therethrough. The working fluid circuit further comprises a heater configured to circulate the working fluid in heat exchange relationship with a hot fluid to vaporize the working fluid. The system further comprises serially arranged first expander and second expander fluidly coupled to the working fluid circuit and disposed between the high pressure side and the low pressure side thereof. One of the expanders drives a load and the other expander drives a pump or compressor fluidly coupled to the working fluid circuit between the low pressure side and the high pressure side thereof. A cooler is further arranged and configured to remove heat from the working fluid in the low pressure side of the working fluid circuit.

摘要： A heat engine system comprises a first heat exchanger, an expander, a second heat exchanger and a valve assembly. The first heat exchanger is in fluid communication with a heat source for heating a working fluid therein. The expander is downstream the first heat exchanger and is in fluid communication therewith for receiving the heat working fluid. The second heat exchanger is downstream the expander and in fluid communication therewith for cooling down the working fluid received therefrom. The valve assembly is in fluid communication with the second heat exchanger and the expander for providing for selectively injecting the expander with cooled working fluid from the second heat exchanger.

摘要： A hydrogen separation system and membrane is described for extracting hydrogen from gasifier streams at near atmospheric pressure and ambient temperature conditions. The system can be inserted between a small gasifier and an internal combustion engine which runs a genset to optionally co-produce hydrogen and electricity. The hydrogen is used in a number of important industrial processes.
