2019-9-1  Solvent storage can increase the operating envelope of gas fired CCS power plants by +/-10% of net electricity output. • Solvent storage can decouple electricity and CO 2 output for up to 3 h with 6200m 3 of additional solvent inventory.. Controlled extraction by throttling the low pressure turbine of the combined cycle is the preferred strategy for delayed solvent regeneration.

Combined Cycle Plant for Power Generation- Introduction

The most common type of combined cycle power plant utilizes gas turbines and is called a combined cycle gas turbine (CCGT) plant. Because gas turbines have low efficiency in simple cycle operation, the output produced by the steam turbine accounts for about half of the CCGT plant output.
