Hydrogen transfer heating/cooling systems and methods of use thereof

A method to effect temperature change in an environment, comprising:

• providing a system to effect temperature change, comprising:
• a plurality of container apparatus pairs, each container apparatus pair including
• a first container apparatus comprising a first container to store a metal hydride therein at a storage pressure greater than ambient pressure, and a first heat exchanger in thermal communication with the first container;
• a second container apparatus comprising a second container to store a metal alloy therein, the metal alloy being capable of absorbing hydrogen atoms at a pressure less than the storage pressure of the metal hydride, and a second heat exchanger in thermal communication with the second container;
• a conduit coupled between the first container and the second container, the conduit in communication with the metal hydride and in communication with the metal alloy;
• a valve disposed in the conduit to control communication between the metal hydride and the metal alloy;
• a first fluid circulation means comprising a first fluid flow passage to contain a first fluid, the first fluid circulation means arranged to operate with the environment and the first heat exchangers of the container apparatus pairs;
• the first fluid flow passage being arranged for the first fluid to pass through the environment and selectively modifiable for the first fluid to pass through one or more of the first heat exchangers;
• a second fluid circulation means comprising a second fluid flow passage to contain a second fluid, the second fluid circulation means arranged to operate with the environment and the second heat exchangers of the container apparatus pairs;
• the second fluid flow passage being arranged for the second fluid to pass through the environment and selectively modifiable for the second fluid to pass through one or more of the second heat exchangers;
• selectively modifying the first fluid flow passage by operation of one or more valves to open and/or close one or more segments of the first fluid flow passage and change a flow path of the first fluid within the first fluid flow passage to include or exclude flow passing through one or more of the first heat exchangers;
• and
• selectively modifying the second fluid flow passage by operation of one or more valves to open and/or close one or more segments of the second fluid flow passage and change a flow path of the second fluid within the second fluid flow passage to include or exclude flow passing through one or more of the second heat exchangers.
