Abstract:
A storage tank 10A has a heat insulating material layer 14 formed on the outer side of a partition wall 12 that has a container shape. The inside of the storage tank 10A is divided into two storage spaces V1, V2. The first storage space V1 stores liquefied hydrogen LH2 and the second storage space V2 storing slush hydrogen SH2. A plurality of fins 18 are disposed on the partition plate 16 so as to promote heat transfer between the liquefied hydrogen LH2 and the slush hydrogen SH2 and to reduce the amount of evaporation gas from the liquefied hydrogen LH2. An escape pipe 20 is connected to the storage space V1, and the fuel supply pipes 24a, 24b are connected to the storage spaces V1, V2, respectively. The fuel supply pipes 24a, 24b are connected to a combustor 26 via the main fuel pipe 24.
Abstract:
A liquid storage tank comprising an outer container wherein the outer container is rigid and has at least one inner container disposed within the outer container. The at least one inner container contains at least one stored liquid which may be refilled from a surface vessel or host facility. The at least one inner container is flexible and pressure balanced while the volume of the outer container remains fixed, and the volume of the at least one inner containers is variable. Disposed on the outer container is a balance assembly containing an isolation valve, a check valve, and a flexible bladder. The balance assembly allows for the hydrostatic pressure to be maintained during chemical dosing and tank raising operations.
Abstract:
Device for storing and releasing fluids at nearly constant pressure, the fluids including a gas and a liquid, includes an assembly of substantially identical reservoirs (1), where the reservoirs include: a portion containing the gas (G) and a portion containing the liquid (L), an element (23) of separation between the gas and the liquid in the reservoir (1), an inlet orifice (36) and an outlet orifice (36) for the gas, an inlet orifice (35) and an outlet orifice (35) for the liquid. The reservoirs (1) have a cylindrical outer envelope (100) made up of at least one metal tube (101) of the type of those used for gas pipelines and oil pipelines, for which: the external diameter is more than 32 inches (813 mm); and the ratio of the length thereof to the outer diameter thereof is greater than 8.
Abstract:
Provided are a subsea storage tank for fluids and a method for building and installing the same. An exemplary embodiment of the present invention provides a subsea storage tank, including: a body having a storage space therein and formed of light weight concrete inner and outer sides of which are watertight coated or plated; a ballast placed on the body of the subsea tank; and a separation unit disposed inside the body and partitioning the storage space upper and lower, the separation unit being movable vertically in the storage space in accordance with the degree of storage fluid filling.
Abstract:
The invention provides methods and systems for tagging carbon dioxide to be stored in a geologic formation. In some embodiments, a method includes: providing a carbon dioxide tracer that is quantifiable and distinguishable versus non-anthropogenic produced carbon dioxide; providing carbon dioxide to be stored in the geologic formation; determining what portion of the carbon dioxide is anthropogenic produced carbon dioxide; and mixing a predetermined quantity of the carbon dioxide tracer with the carbon dioxide stored to develop a tagged quantity of carbon dioxide for storage in the geologic formation. In some embodiments, a system for tagging a stream of carbon dioxide includes a tagging module and a mixing module. Tagging module includes a carbon dioxide tracer that is quantifiable and distinguishable versus non-anthropogenic produced carbon dioxide. Mixing module includes mechanisms for containing and injecting the carbon dioxide tracer into a stream of carbon dioxide.

Abstract:
An apparatus for compressing a gas and its uses are disclosed. The apparatus comprises a fixed-volume container having a hollow and a moveable element subdividing said hollow into a first variable-volume portion and a second variable-volume portion, the second variable-volume portion having an opening for introducing therein a hydraulic and/or pneumatic fluid under pressure, for causing an increase in the volume of said second variable-portion by moving said moveable element, thereby, consequently, decreasing the volume of the first variable-volume portion and compressing a gas contained therein.
Abstract:
A container (1) having a first compartment (3) and a second compartment (5) separated by a movable gas impermeable partition (7) is used for storing and dispensing a gas for use in a process and receiving and storing a gas recovered from the process. Fresh gas is dispensed (9) from the first compartment (3) for use in a process and recovered gas is fed (11) to the second compartment (5), whereby a volume of the second gas displaces a volume of the first gas by movement of the partition (7) to enlarge the second compartment (5) relative to the first compartment (3).
