Publication number: 20230392749Abstract: A compressed gas energy storage system may include an accumulator for containing a layer of compressed gas atop a layer of liquid. A gas conduit may have an upper end in communication with a gas compressor/expander subsystem and a lower end in communication with accumulator interior for conveying compressed gas into the compressed gas layer of the accumulator when in use. A shaft may have an interior for containing a quantity of a liquid and may be fluidly connectable to a liquid source/sink via a liquid supply conduit. A partition may cover may separate the accumulator interior from the shaft interior. An internal accumulator force may act on the inner surface of the partition and the liquid within the shaft may exert an external counter force on the outer surface of the partition, whereby a net force acting on the partition is less than the accumulator force.Type: ApplicationFiled: August 23, 2023Publication date: December 7, 2023Inventors: Cameron Lewis, Andrew McGillis, Davin Young, Curtis Vanwalleghem

Patent number: 9939112Abstract: Apparatus for use with fluid-processing plant configured to generate and store pressurized fluid. Fluid-processing plant is spaced apart from body of water. Apparatus includes variable-buoyancy assembly positioned in body of water in such way that buoyancy force urges variable-buoyancy assembly to move toward surface of body of water. Apparatus also includes non-collapsible fluid-line assembly positionally anchored, at least in part, underground in such way that non-collapsible fluid-line assembly extends, at least in part, into body of water. Non-collapsible fluid-line assembly fluidly connects fluid-processing plant and variable-buoyancy assembly together in such way that non-collapsible fluid-line assembly conveys pressurized fluid between fluid-processing plant and variable-buoyancy assembly.Type: GrantFiled: October 29, 2014Date of Patent: April 10, 2018Assignee: Hydrostar Inc.Inventors: Cameron Lewis, Curtis VanWalleghem, Kyle Ryan
