Abstract:
The present invention is a bi-propellant system comprising a gelled liquid propane (GLP) fuel and a gelled MON-30 (70% N 2 O 4 + 30% NO) oxidizer. The bi-propellant system is particularly well-suited for outer planet missions greater than 3 AU from the sun and also functions in earth and near earth environments. Additives such as powders of boron, carbon, lithium, and/or aluminum can be added to the fuel component to improve performance or enhance hypergolicity. The gelling agent can be silicon dioxide, clay, carbon, or organic or inorganic polymers. The bi-propellant system may be, but need not be, hypergolic.

In one implementation, the present invention provides a method of creating scalable, easily deployable storage of natural gas and thermal energy by assembling an array of interconnecting, modular gas clathrate hydrate storage units.
Abstract:
A method for storing natural gas by adsorption which comprises separating an available natural gas in an infrastructure side (10) into a low carbon number component mainly containing methane and ethane and a high carbon number component mainly containing propane, butane and the like, and storing the low carbon number component by adsorption in a first adsorption tank (16) and storing the high carbon number component by adsorption in a second adsorption tank (18). The method can solve the problem that the high carbon number component condenses within a pore of an adsorbing agent and hence the adsorption of the carbon number component, the main component of natural gas, is inhibited, and thus improves the storage density. Accordingly, the method can be used for ensuring a high storage density also for an available natural gas. An adsorbing agent for use in the method is also disclosed.
Abstract:
Improved methods, systems, and devices for filling fuel tanks, particularly compressed natural gas (CNG) fuel tanks, are provided. Such methods, systems, and devices enhance heat rejection when the fuel tank is being filled to a temperature lower than that if such methods, systems, and devices were not used. Pressure sensor logic on a fuel station will be less prone to error in gauging the mass of the fuel in the tank, enabling the tank to be filled more accurately and fully. To enhance heat rejection, the fuel tank may be provided with a heat sink to passively facilitate heat transfer from the fuel tank interior to the exterior. Alternatively or in combination, the fuel tank can be provided with a fuel flow channel through which fuel from the fuel tank interior is circulated. The fuel flow channel can be actively cooled with a fan or water cooling system.
Abstract:
The present invention relates to a device for storing gas under pressure comprising an inner cylindrical pressure vessel (1), the pressure vessel (1) comprising pipe connection (7). According to the present invention, the device is characterized in that the inner cylindrical pressure vessel (1) is arranged inside an outer vessel (3), whereby a substantially annular space (2) is formed between the inner pressure vessel (1) and the outer vessel (3), wherein the annular space (2) between the inner pressure vessel (1) and the outer vessel (3) is filled with a fluid, the outer vessel (3) further comprising venting means (5) at or in the vicinity of the highest point (4, 6) of the outer vessel (3).
Abstract:
A cryogenic vessel system for containing cryogenic fluid (3) wherein heat leak into the vessel interior (2) is counteracted by refrigeration generated from energy provided by a pulse generator (11) which provides a pulse to a working gas which is expanded at the cold end of a pulse tube (10) to provide refrigeration to a cold heat exchanger (13) which is at least in part within the vessel interior (2) .
Abstract:
A method for obtaining gas-sealing around rock chambers or rock storage chambers. Hydrates of petroleum gas are made in pores and cracks in the rock (11) around the rock chamber (1) with the aid of cooled water and a suitable gas mixture of petroleum gases which are injected at suitable pressure into respective boreholes (3, 4, 5, 6, 7) in the rock around the rock chamber (1).
Abstract:
