Definitions
- the present invention relates to a hydrogen reforming plant for producing hydrogen. More particularly, the present invention relates to a hydrogen production plant that utilizes a renewable energy source for hydrogen compression and energy storage.
- Hydrogen is an ideal candidate for replacing fossil fuel because it can be readily made available from domestic renewable resources. Hydrogen is also nonpolluting, storable, transportable and clean, making it a valuable fuel. However, the lack of cost- effective hydrogen storage and transport, particularly for an onboard vehicular system, is a major impediment to its widespread use. Improvements in the energy densities of hydrogen storage systems, reductions in cost, and increased compatibility with available and forecasted systems are required before viable hydrogen energy use will be realized.
- the present invention provides a system and method for utilizing a renewable resource, such as wind energy or solar energy, for the compression or refrigeration of hydrogen as means for energy storage.
- a renewable resource such as wind energy or solar energy
- the compressed hydrogen may comprise a form of mechanical energy storage and furthermore gains an added value as a transportable fuel for vehicle use.
- a hydrogen production system includes a reformer for producing hydrogen from a hydrocarbon fuel, a compressor for compressing the hydrogen produced by the reformer into a compressed state, a renewable energy source for converting a renewable resource into electricity for powering the compressor and a storage device for storing the compressed hydrogen from the compressor.
- a hydrogen production system comprising a catalytic reformer, an electric source, a compressor and a storage device.
- the catalytic reformer produces hydrogen from a hydrocarbon fuel using one of an endothermic reforming process and steam generation.
- the electric source provides thermal energy for at least one of the endothermic reforming process and the steam generation.
- the compressor compresses the hydrogen produced by the reformer.
- the storage device stories the compressed or liquefied hydrogen from the compressor.
- a hydrogen production system comprising a catalytic reformer, a compressor and a storage device.
- the catalytic reformer produces hydrogen from a hydrocarbon fuel and the compressor compresses the hydrogen produced by the reformer into one of a compressed and a liquefied state.
- the storage device stores the compressed or liquefied hydrogen from the compressor.
- the compressed hydrogen is pumped to a hydrogen tank of a vehicle and stored as a mechanical energy source and a chemical energy source.
- a hydrogen production system comprising a reformer, an electrolyser, one or more compressors, one or more renewable energy sources and one or more storage devices.
- the reformer produces hydrogen from a hydrocarbon fuel.
- the electrolyser produces additional hydrogen by electrolysis.
- the compressors compress the hydrogen produced by the reformer and the electrolyser and the renewable energy sources convert a renewable resource to electricity for powering the electrolyser and the compressor.
- the storage devices store the compressed hydrogen from the compressor.
- Figure 1 is a schematic view of a hydrogen production system according to an illustrative embodiment of the invention.
- Figure 2 illustrates the on-board components of a hydrogen-powered vehicle suitable for implementing an illustrative embodiment of the invention.
- Figure 3 is a schematic view of a hydrogen production system providing levered production of hydrogen using the combination of a chemical reformer and electrolysis according to one embodiment of the present invention.
- the present invention provides an efficient, low cost hydrogen production system that utilizes renewable energy sources.
- the invention will be described below relative to an illustrative embodiment. Those skilled in the art will appreciate that the present invention may be implemented in a number of different applications and embodiments and is not specifically limited in its application to the particular embodiment depicted herein.
- renewable source or “renewable energy source” refers to any energy source with a natural replenishment rate that augments its own stock (or biomass) at a non-negligible rate.
- Renewable resources are generally capable of being replenished at least as fast as the renewable resource is used, although this need not be the case.
- Renewable sources include, but are not limited to, wind, solar energy, geothermal energy, biomass, waste, wave energy and hydro energy.
- nonrenewable energy sources draw on finite resources that will eventually dwindle.
- renewable energy converter refers to a system or device that converts a renewable resource to another form of energy, such as electricity.
- the term "reforming”, and the like, refers to a chemical process that reacts hydrogen-containing fuels in the presence of steam, oxygen or both into a hydrogen-rich gas stream.
- electrolysis refers to an electrochemical process that dissociates water into hydrogen and oxygen using electricity.
- compress refers to a process of increasing the pressure of hydrogen to make the hydrogen suitable for storage.
- liquefy refers to a process of compressing hydrogen, which may incorporate refrigeration to reach a lower temperature, into a liquefied state and is intended to be included in the term "compress”.
- FIG. 1 illustrates a hydrogen production system 100 according to an illustrative embodiment of the invention.
- the system 100 comprises a fuel reformer 10 for producing hydrogen by converting an input fuel, fed from an input fuel supply 15, into a hydrogen gas in a process known as "reforming".
- the system includes a hydrogen compressor 20 for compressing the hydrogen gas produced by the reformer 10 into a compressed or liquefied state by increasing the pressure and/or reducing the temperature of the hydrogen.
- the system 100 further includes a hydrogen storage device 30 for storing the hydrogen after compression.
- the storage device 30 can include any appropriate storage media suitable for storing or transporting hydrogen.
- a renewable energy converter such as a windmill 40, photovoltaic cell or other source known in the art, is used to convert a renewable source, such as wind, solar energy, a geothermal resource, biomass, waste, wave energy and hydro energy, to electricity to power the hydrogen compressor 20.
- a renewable source such as wind, solar energy, a geothermal resource, biomass, waste, wave energy and hydro energy
- the illustrative hydrogen production system 100 further produces hydrogen with little or no emission produced as a byproduct.
- the hydrogen production system 100 is further capable of at least partial or total sequestration of carbon dioxide (CO 2 ), which provides additional environmental benefits.
- the rate of hydrogen generation from the system 100 may be regulated according to the power available from the renewable energy converter 40, resulting in a more efficient, cost effective and capacity augmented hydrogen generation and storage system 100 based on renewable energy.
- the reformer 10 may comprise catalytic reformer that produces hydrogen from a hydrocarbon fuel using one of an endothermic reforming process and steam generation.
- the reformer may be a steam reformer, autothermal reformer, partial oxidation reformer or other suitable device known in the art for separating hydrogen from hydrocarbons, for example, in a hydrocarbon fuel, to produce hydrogen, such as the autothermal cyclic reforming (ACR) process developed by General Electric Energy and Environmental.
- the input fuel that the reformer 10 uses to produce hydrogen may comprise a hydrocarbon fuel, such as, but not limited to, natural gas (methane), liquid and gaseous hydrocarbon fuels, and carbonous fuels, such as coal.
- the hydrogen can be inexpensively produced by a thermal reforming process using natural gas at less than
- the reformer 10 comprises a steam reformer, which converts methane (and other hydrocarbons in natural gas) into hydrogen and carbon monoxide by reaction with steam over a nickel catalyst.
- Conventional steam reformers currently in wide commercial use comprise a reformer section consisting of a catalyst material, which promotes the reforming reaction and a burner to supply heat for the endothermic reforming reaction.
- a steam source is typically comiected to the reformer section to provide steam by vaporizing water.
