Mobile energy carrier and energy store

Abstract

A mobile energy carrier with which energy in the form of materials from zones distributed widely throughout the world, for example with a large amount of solar energy, wind energy or other CO 2 -neutral energy, for example the equator, can be transported to zones where there is a high energy requirement, for example Europe.

1 - 8 . (canceled) 
     
     
         9 . A method for energy transport and/or energy storage, comprising:
 obtaining electrical energy from at least one of sun, wind, biogas, and excessively produced electrical energy;   producing, from the electrical energy, an energy carrier formed as an elementary metal;   changing the energy carrier to a transportable or storable species;   transporting or storing the energy carrier in the transportable or storable species; and   releasing the electrical energy stored in the energy carrier by reaction with at least one of water and oxygen.   
     
     
         10 . A mobile energy carrier and/or energy, comprising:
 an elemental electropositive metal.   
     
     
         11 . The mobile energy carrier as claimed in  claim 10 , wherein the elemental electropositive metal is a transportable and/or storable form of at least one among the group of lithium alloy, lithium hydride and a lithium derivative. 
     
     
         12 . The mobile energy carrier as claimed in  claim 10 , wherein the elemental electropositive metal comprises an alkali and/or alkaline earth metal. 
     
     
         13 . The mobile energy carrier as claimed in  claim 10 , wherein the elemental electropositive metal comprises at least one of the group of zinc, magnesium, aluminum, and a lanthanide group metal. 
     
     
         14 . The mobile energy carrier as claimed in  claim 10 , wherein the elemental electropositive metal is produced from an oxygen compound as a raw material. 
     
     
         15 . A method of producing fertilizers containing nitrogen, comprising:
 forming lithium nitride from lithium; and   forming fertilizer from the lithium nitride.   
     
     
         16 . Primary electrochemical cells, comprising:
 lithium.
