Abstract
CO2 is separated from waste gases by known technical methods and stored in underground cavities. By additions to the CO2, according to the invention, of H2 or NH3, methanogenic bacteria, bacteria substrate, catalysators and/or inhibitors the CO2 is reduced during the underground storage to CH4. The storage is possible in aquifer, natural gas reservoirs or oil and/or gas generating rock formations. Due to the equal volumes of CO2 and CH4 the process is a closed cycle and of constant pressure. Natural gas becomes a renewable energy.
Claims6
Method for separating CO2 from waste gases of combustion plants, storing said CO2 and bacterially converting said CO2 to CH4, comprising the steps of:
- injecting said separated CO2 in an underground natural reservoir in geological porous or finely cleaved sediment of an underground gas or oil field or aquifer which forms said natural reservoir, said reservoir being surrounded and covered by non-porous material;
- and
- converting said CO2 to CH4 through bacterial conversion and storing said CO2 and CH4 gases, within said reservoir.
