An energy utilization system can initially store a plurality of different fuels in a fuel storage pod before choosing a fuel ratio with a blend module connected to the fuel storage pod. The fuel ratio chosen in response to an electrical generation parameter tracked by the blend module. The supply of at least two of the plurality of different fuels to a power generator with the chosen fuel ratio allows for the combustion of the supplied fuels with the electrical power generator to create electricity.

An intelligent fuel storage system can consist of a storage pod connected to a storage module with the storage pod having a plurality of separate storage vessels each residing below a ground level. The storage pod may concurrently store a first volume of a first fuel and a second volume of a second fuel prior to altering the first and second volumes in accordance with a performance strategy generated by the storage module to provide a predetermined blend of the first fuel and second fuel with at least a threshold volume and at least a threshold pressure.

Individual square shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant square tilling shape for maximized structural strength and material use efficiency. Internal square shaped modules are assembled and encased by external square shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal square shaped modules drain into square shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.

Method and apparatus for blending first and second fuels for use by a combustion mechanism, such as a motor vehicle. The first and second fuels are stored in storage vessels of a fuel storage pod in a fuel storage ratio of total respective volumes established by a storage controller circuit of a storage module responsive to a predicted demand level. A blended fuel ratio is selected by a blend controller circuit of a blend module in response to an imminent demand parameter of a selected combustion mechanism, with the blended fuel ratio being different from the fuel storage ratio. A blend of the first and second fuels is thereafter dispensed to the selected combustion mechanism at the blended fuel ratio. The first fuel may be hydrogen (H2), and the second fuel may be a selected hydrocarbon, such as propane, butane, methane, hexane, gasoline or diesel.

Method and apparatus for adaptively adjusting the storage of fuels for use in a fuel blending process. First and second fuels are stored in storage vessels at an initial volumetric fuel storage ratio. A storage controller executes a performance strategy to adaptively adjust at least one storage parameter in response to a predicted or detected change in operating conditions of the system. The performance strategy can include increasing a storage pressure of at least one of the fuels and/or changing a total number of storage vessels used to store the respective fuels. A dispensing mechanism transfers a blended fuel formed from the first and second fuels in accordance with the execution of the performance strategy. The fuels can take a variety of forms including hydrogen (H2), oxygen (O2), hydrocarbons, etc. The blended fuel may be dispensed by a fueling station to a motor vehicle.

A subsea vessel includes an outer layer of non-corrosive material and an inner layer of high-strength material that both corroborate in a subsea environment to withstand external pressure and prevent corrosion. The subsea vessel further includes a cavity surrounded by the inner layer and outer layer for providing storage in and protection from the subsea environment. The cavity is accessible via an opening that extends through the inner layer and the outer layer. The opening can be opened and closed with a cooperating cap that impermeably seals the cavity. The cap may include a number or connection mechanisms for being selectively secured to the opening. In addition, the cap may include a portion formed of a high-strength material and a portion formed of a non-corrosive material.
