The invention relates to a liquid air energy storage system.
The storage system includes a cryocooler, a dewar, and a
Sterling engine. The cryocooler cools a tip of a cold head to
cryogenic temperatures, the cryocooler further includes a
heat sink to reject heat from the cryocooler and a cold head
that protrudes into a dewar through a cryocooler cavity, the
cold head to condense ambient air to create liquified air in
the dewar. The dewar holds the liquified air at low temperatures,
the dewar having the cryocooler cavity and a Stirling
cavity. The Stirling engine drives an electric generator, the
Stirling engine further including a cold finger protruding
into the dewar through the Stirling cavity, the cold finger to
move the liquified air from the dewar to a Stirling heat sink;
the Stirling heat sink to expand the liquified air; and the
electric generator to generate output electricity.
