Definitions

  • the innovation herein proposed describes an electricity generation system based on Nitrogen and its use.
  • the electrical energy generation from hydrogen is one of the alternatives that is under research.
  • the distributed energy becomes even more important due to the following factors:
  • each residence could have its local (private) generation, that is, small generators of electric energy.
  • This patent presents an alternative form of clean, renewable and distributed electric energy generation, based on Nitrogen.
  • the Nitrogen is the main element in air (about 78%), therefore a renewable source of electric energy generation. Moreover, the equipment herein described represents a clean and distributed form of electricity generation.
  • the Nitrogen can be stored in liquid form facilitating the transport and positioning, where the energy is necessary and, therefore its use as fuel for distributed, clean and renewable generation of electric energy.
  • the considered system is an electricity generator that uses the ambient temperature to heat up and vaporize liquid Nitrogen, which is stored at low temperature, and is pumped at high pressure through a heat exchanger.
  • the high pressure vaporized Nitrogen gas is expanded in an expander, which generates mechanical power that drives an electricity generator.
  • the present invention is composed by an electric energy generation system using liquid Nitrogen, as shown in FIG. 1 , where V represents the storage vessel of liquid Nitrogen, B is a pump, TC is the heat exchanger, D a control device, EXP expander and CEE electric energy converter. There is, also, a set of valves (not shown in figure) that controls the Nitrogen flow in the system. The valves are also used for the protection and the re-start of the system.
  • FIG. 1 illustrates the basic principle of operation.
  • the Liquid Nitrogen initially stored in a pressure vessel, V, is pumped to the operating pressure of the system in the pump B, after which it is directed into the heat exchanger, TC.
  • the heat exchanger works in a similar form to a car radiator, however, instead of using air to cool, it uses air to heat the Nitrogen.
  • the liquid Nitrogen passes through pipes that compose the heat exchanger, where it is heated and vaporized by a stream of air at ambient temperature. After that it is expanded in an expander, EXP, generating mechanical power, which is converted into electricity by an electrical generator (CEE).
  • EXP expanded in an expander
  • CEE electrical generator
  • the Nitrogen flow to the expander inlet is controlled by a device, D.
  • the considered system is modular and several of them can be connected to increase the capacity of electric energy generation (power and energy), through the combination of Nitrogen storage vessels in parallel to the heat exchanger or by the combination of some Nitrogen storage vessels and heat exchanger in parallel to the expander as shown in FIG. 2 , and others.
  • the system has a low cost to generate a clean, renewable and distributed energy:
