Cycling Reactor System


Technology Overview 

Our solar receiver/reactor employs a bubble column medium together with a cavity solar receiver.  Concentrated solar radiation is first absorbed on the inner side of the cavity.  The absorbed heat is then transferred to the heat transfer fluid bath.  The cavity receiver and bubble column are integrated within the insulated pressure vessel and different metal/metal oxides.  Reactant and non-reactant gases and configurations for the solar receiver can be employed. 


Potential Applications 

A primary focus of concentrated solar thermal energy has been electricity generation.  There is also potential for off-grid and large scale industrial settings such as mineral and petroleum processing facilities and the global agriculture sector.


Key Features & Benefits 

The receiver and bubble column are integrated in the insulated pressure vessel.  Concentrated solar radiation is absorbed on the inner side of the cavity and then transferred to the fluid bath.

•       Mitigates re-radiation heat losses between the solar cavity and gas heating zone.

•       High thermal conductivity of the metal oxides,

•       Eliminates temperature distribution inside the solar cavity.

•       Eliminates complications with reticulated porous ceramic (e.g., low thermal conductivity, gas-tightness and gap between the ceramic and receiver wall).

•       High outlet temperatures (of up to 1350 °C) suitable for high thermal efficiency power plants;

•       Continuous, steady-state operation replacing the need for semi-batch reactors.

•       High fuel conversion efficiency (> 98.0%);

•       Continuous output for either dispatachable power or continuous chemical processing.

•       Compatibility with commercially available technologies.
