GE Vernova Inc. and Saudi Arabia’s Ash Sharqiyah Operations & Maintenance Company (ASHOMCo) announced the completion of three Front-End Engineering Design (FEED) studies analyzing the possibility to lower the net carbon emissions of three cogeneration plants located in the Kingdom of Saudi Arabia.
GE Vernova completed the assessment of pre-combustion and post-combustion technologies at the three plants powered by GE Vernova’s 7E and 7F gas turbines and delivering up to 920 Megawatt (MW) of combined power and 1400 tons/hr of steam, a capacity equivalent to the average power needed by 920.000 Saudi homes.
GE Vernova accomplished a hydrogen-readiness assessment for the three power plants as well as conducting assessments to improve performance and costs in the installation of possible carbon capture, utilization, and sequestration (“CCUS”) systems at the three power plants.
GE Vernova 7E and 7F gas turbines can already operate today with hydrogen blend at up to 100 percent with modifications to the Standard Combustors. GE Vernova’s FEED studies explored solutions to enable operations using blends of natural gas and hydrogen, with hydrogen accounting for up to 32 percent by volume at those three plants, and defined the necessary modifications to the existing combustor systems with view to achieving this level of hydrogen blending.
The studies also focused on retrofitting the three power plants with technology capable of capturing up to 95 percent of the plant’s carbon dioxide (CO2) emissions. The studies concluded that the integration of GE Vernova’s Exhaust Gas Recirculation (EGR) system could lead to a reduction of more than 7 percent of the total cost of the carbon capture facility, as compared to installing CCS without the EGR system, and 6 percent reduction of carbon capture operational costs per year, at the site conditions considered in the study.
