Project Overview and ObjectivesProject Overview: Funding: 7,101,737– DOE: 5,674,533– Recipients: 1,427,204 Work Period: 10/1/2019 - 9/30/2021Project Objectives: Complete a Front-End Engineering and Design (FEED) study for installing theLinde-BASF advanced aqueous amine solvent-based post-combustion CO2capture technology (PCC) at an existing domestic natural gas-fired combinedcycle (NGCC) power plant within Southern Company’s portfolio of assets. Provide a reference case for a more detailed understanding of CO2 capturecosts in a commercial application that will support the development of costeffective, environmentally sound, and high performing technologies for thereduction of CO2 emissions from NGCC plants.3

Linde-BASF Post-Combustion Carbon Capture (PCC) TechnologyReduced capital costs / energycosts Optimized BASF OASE bluesolvent Efficient CO2 capture from lowpressure sources Longer solvent life (can handlehigher O2 conc) Lower solvent circulation rateNotable Linde-BASF processimprovements(C, E) Dry bed water wash design tominimize solvent losses(G) Stripper regeneration at 3.4 barsreducing CO2 compressor cost andpower consumption(I) Advanced Stripper InterstageHeater to reduce regenerator steamconsumption.4

Linde-BASF Post-Combustion Carbon Capture (PCC) Technology Technology tested from 2009-2017 in two pilot plants– Different flue gas sources– Wide range of flue gas compositions and impurities– Achieved Technology Readiness Level of 6– Multiple process design improvements achieved OASE blue solvent– Advanced aqueous amine solvent– Favorable kinetics and reduced steam energy requirements– Demonstrated solvent stability– Lower solvent circulation ratePrior NGCC CO2 capture studies conducted in2011 and 2018 will be leveraged5

Host Sites for Evaluation Alabama Power’s Plant Barry Units 6 and 7– Located in Bucks, AL– Each unit: (2) GE 7FA gas turbines - (1) Vogt triple pressureHRSG - (1) GE TC2F D11 steam turbine, 525 MW net– Began commercial operation in May 2001– Estimated storage costs at 3-4/ton from extensive prefeasibility geological studies Mississippi Power’s Plant Daniel Units 3 and 4– Located in Moss Point, MS– Each unit: (2) GE 7FA gas turbines - (1) Vogt triple pressureHRSG - (1) GE TC2F D11 steam turbine, 525 MW net– Began commercial operation in May 2001– Estimated storage costs at 3-5/ton from pre-feasibilitygeological studies8

Task 2: Requirements Definition and Host Site Evaluation Linde and SCS evaluated performance,utility availability, regulatory impacts, andplot space to select Plant Daniel host site A basis of design detailing major boundaryconditions and operating scenarios wascompleted Developed PCC plant concept:– 2 PCC Compression trains withcommon utility supply and facilitiessupport infrastructure– Each train includes 2 DCC columns, 2absorbers, and 1 desorber column.– Each compression train includescompressor w/ dryer and processcondensate handling3D design for 550 MW PCC plant based on earlier work9

Task 3: Conceptual DesignLinde Scope (ISBL):– BASF completed basic design basedon OASE blue solvent technology,including preliminary heat andmaterial balances and key equipmentsizing– Linde has progressed basicengineering including development ofthe first version of PFD, detailed heat& material balances, P&ID, and plotplan.SCS Scope (OSBL):– Evaluating optimum integration ofthe steam cycle with the carboncapture system– Evaluating integration of requiredutilities, including necessaryadditions/upgrades– Evaluating permitting requirementsfor air and effluents– Reconciliation between Linde andSCS design standards10

Basic Engineering in DevelopmentKey progress:- Design basis documentdetailed to summarizequality & quantity of utilityrequirements and conditionsat scope transitions- Continued Linde-SCSinteraction to define utilitysource points & availability- Integration aspects relatedto steam cycle, flue gas ductlayout considered11

Synergy: DE-FE00031888, Project ECO2S Phase III 21.9M project, led by Southern States Energy Board (SSEB) Project partners include 16 universities, labs, and private companies Project remains under negotiation Prepare for a regional CO2 host site in Kemper County, MS– Previous phase identified potential for complex capable of storing 900 millionmetric tons of CO 2– Current efforts will fully characterize the site through additional test well drills– CO2 to be sourced from Plant Ratcliffe (NGCC), Plant Daniel (NGCC), and PlantMiller (Coal) Project deliverables– Final site geologic characterization– CO2 capture feasibility assessments for proposed host sites– UIC Class VI Permit to Construct application12

Challenges due to COVID-19: Travel restrictions eliminated the possibility of having inperson kickoff and host site visits– Team was able to build rapport and select the host site through virtualmeetings HAZOP scheduled at the end of Task 3 / beginning of Task 4– Travel restrictions are expected to still be in place– There is a 7-hour time difference between the Linde Engineering teamand the SCS engineering team– Team is exploring options for rescheduling or executing virtually13

Summary Southern Company and Linde assembled a diverse team to develop a FEED studywith detailed cost and schedule estimates. Despite major changes in work practices and plans due to the COVID-19pandemic, the project team has adapted and continued the work.– No site visits and no in-person team kickoff.– Remote working conditions will continue for foreseeable future for many team members. The project team is working to complete basic engineering by 3 rd quarter.– Primary basis of design complete.– Initial Process Flow Diagrams complete.– Equipment specifications and preliminary P&IDs in development. HAZOP will be conducted as basic engineering shifts to detailed design.– Virtual options are being considered due to travel restrictions; time zone differences pose achallenge.14
