The process is then operated with the recycled, combustible mixture. The reaction product from the fuel is almost exclusively CO₂ – which is recycled back into fuel.
Because a large proportion of the CO₂ comes from the geogenic source inherent in the process, the efficiency of the plant does not have to be extremely high in order to replace the fossil fuel.
As the CO₂ produced is continuously recycled, no certificates need to be purchased for the CO₂ that is not emitted.
