Definitions

• the invention relates to a method of storing solar energy in conjunction with reducing the CO 2 content of air.
• the invention is based on the object of providing a method of producing and storing energy from solar energy while simultaneously effecting a reduction in the CO 2 content of the air.
• the method according to the invention comprises the following method steps:
• the remaining fraction may be converted in known manner into energy or an energy source like heat, electricity or hydrogen.
• the land, on which the plant biomass had been generated prior to the conversion into charcoal may be replanted in suitable manner and thus be used again for producing photosynthetic biomass and charcoal therefrom.
• Charcoal which has been produced from photosynthetic biomass in known manner, is stored in a bunker plant.
• the charcoal is infed into the bunker plant and outfed therefrom upon request by using technically conventional conveying means.
• subterraneous cavities such as present in a coal, ore or salt mine or the like as well as known above-ground constructions are considered for such bunker plants.
• the charcoal storage is intended for time periods of up to 20 years or more.
• the charcoal is stored under non-ignitable protective gas having a density greater than air such as CO 2 or, if desired, a rare gas.
• Each bunker plant is equipped with known means in a manner such that the stored charcoal is protected from water ingress and/or excess temperatures.
• a number of mutually separate charcoal reservoirs may be provided in a given bunker plant.
• the CO 2 content of the air can be reduced if either (a) wood production is increased whereby more CO 2 is removed, and/or (b) production of CO 2 by wood combustion is reduced, whereby the additionally produced wood and/or the non-burned wood is converted into charcoal and stored in accordance with Example 1.
• the conversion into charcoal has the added advantage that during this process valuable side products such as acetic acid and homologues thereof, methanol and acetone are produced and thus are obtained in desired manner from renewable resources and not from fossile sources.
• a typical Texaco plant for coal gasification (Kirk-Othmer, ENCYCLOPEDIA OF CHEMICAL TECHNOLOGY 3rd Ed. Vol. 12, Wiley, New York, pp. 959/960) having a capacity of 2.83 ⁇ 10 6 m 3 /d of raw hydrogenis charged with 1,852 t/d of finely divided charcoal (of which 83.4% are process charcoal).
• charcoal has the advantage of being free of any sulfur and heavy metal catalyst poisons whereby the useful life of the catalysts is prolonged and their efficiency is improved while special gas purification operations become superfluous.
• a typical Texaco plant processing 1,852 t/d or 0.676 mio t p.a. of charcoal is confronted with 25% or 6.1 mio t p.a. of charcoal originating from storage in 2005 whereby 9 such plants can be operated.
• Sizable storage of the charcoal thus may be the foundation of the reliability of the logistics for the solar hydrogen economy.
• the stored charcoal can be accessed for hydrogen production at any desired time because the main amount thereof must remain stored for sustained energy provision by reversing combustion.
• the thus generated amount of CO 2 corresponds to the amount which has been removed from the atmosphere before and which has been bound in the photosynthetic biomass of wood.
• the thus generated amount of CO 2 is thus balanced by the corresponding amount of photosynthetic biomass which has been formed.
• the thus produced hydrogen substitutes other fuels, particularly fuels originating from fossile sources, which form CO 2 on combustion, and preferably serves for generating energy by means of fuel cells.
• reaction (1) may also be conducted such that the synthesis gas, which is obtained by reaction (1), is reacted by known, particularly catalytic processes to form industrial products for use in many technical fields.
• these products are also obtained from renewable resources without requiring recourse to fossile raw materials like crude oil, natural gas or coal.
