The invention relates to a method and installations for reducing the greenhouse gases of fuels and combustibles and to the use of said fuels and combustibles as greenhouse-reduced energy carriers, especially as zero-greenhouse-gas-free fuels in transport. CO2 from renewable sources is separated from pyrolysis gas and/or from flue gas and/or from biogas, and recuperated. The recuperated renewable CO2 is put in a geological repository (sequestered). According to a second possible use, the recuperated renewable CO2 replaces fossil CO2 as a raw material. According to a third possible use, the renewable CO2 is used as a raw material for the production of substantially greenhouse-gas-free synthetic fuels, replacing fossil fuels and thereby avoiding additional fossil greenhouse gas emissions. According to the first option of use, renewable CO2 is removed from the environment, i.e. the atmospheric CO2 content is actively reduced. According to the second option of use, fossil CO2 is directly replaced by renewable CO2, and according to the third option of use, the additional emission of fossil CO2 and thus an increase in atmospheric CO2 content is avoided. The greenhouse effects or greenhouse gas credits or greenhouse gas certificates produced by the three options of use are offset against the greenhouse gas emissions of fossil or renewable or synthetic fuels. The virtual-statistic offsetting of the greenhouse gas credits reduces the greenhouse gas emissions of these fuels, at best down to 0gCO2 equivalent/MJ or down to 0gCO2 equivalent/kWh or down to 0gCO2 equivalent/km. Vehicles using such zero emission fuels will turn into exceptionally environmentally friendly zero emission vehicles, thereby allowing zero emission mobility without developing novel drive technologies. |
