Integrating CCS with biomass and cogen


In Louisiana and Alberta


Strategic Biofuels has reported receipt of a draft Class VI Well Permit from the Louisiana Department of Conservation and Energy (C&E), with the final Permit to Construct anticipated in July, or thereabouts. Strategic Biofuels says this is a major milestone for its $2 billion Louisiana Green Fuels (LGF) BECCS (Bioenergy with Carbon Capture and Storage) project in northeast Louisiana. The project comprises a 100 MW wood-fired power plant designed to deliver carbon-neutral electricity to the grid while capturing and permanently sequestering the CO2


in the company’s sequestration complex, all located in Caldwell Parish. “The journey to secure this permit began five years ago,” said Dr Paul Schubert, CEO of Strategic Biofuels. “We partnered with Geostock Sandia to plan the drilling, data collection and analysis for our Class V sequestration test well, and since have worked together in filing the permit application initially with the US EPA and then refiling with the State of Louisiana to the state’s even stricter requirements for Class VI permits.” Phase I of the LGF project will see construction of the 100 MW wood-fired power plant with dedicated CCS at the Port of Columbia in Caldwell Parish, Louisiana. Burning 1.3 million tons per year of “sustainably sourced” forestry feedstock – including forestry residuals, material that would otherwise be left to decompose or be burnt – the facility will generate a net 75 MW of dispatchable renewable power for the grid, with the balance powering the carbon capture and sequestration operations. “This new demand for forestry feedstocks will be a lifeline to the struggling logging industry in northern Louisiana, which continues to be hard hit by the shutdown of regional pulp and PCpaper

mills,” says Strategic Biofuels. Phase II of the project on the same site is a planned biorefinery to produce biofuels. Once the plant is operational, over one million tons of carbon dioxide will be captured each year and permanently stored in the project’s dedicated geologic reservoir located approximately one mile directly beneath the site. “With this Class VI Permit and its three injection wells the reservoir will have more than three times the CO2


sequestration capacity


needed for Phase I, thus providing ample room for subsequent project expansion,” says Strategic Biofuels. The company notes that LGF will generate annually “over one million high-quality, durable carbon dioxide removal credits (CDRs)”, which will be sold via a strategic collaboration with Carbon Direct. FEED (front-end engineering and design) for the sequestration complex, carried out in conjunction with oilfield services provider SLB (formerly Schlumberger), has been completed. Pre-FEED services for the power and carbon capture facilities are being provided by Kiewit Engineering Group Inc. Process automation is being provided by Emerson, which combines experience in biomass fuelled power plants with that in carbon

capture and storage. To optimise integrated operations,


Emerson will deploy its DeltaV automation platform, along with a “full suite of automation, measurement and reliability technologies”, including Rosemount smart sensing, control valves, isolation valves, pressure protection devices, Micro Motion and Flexim flow and gas analysis systems, and AspenTech data management software. These will provide “the high-fidelity visibility and dynamic optimisation tools required for a first-of-its-kind carbon neutral power system”, says Emerson.


Decarbonising Dow


Meanwhile, in Canada, a 466 MW cogeneration plant with integrated carbon capture is a key element in Dow’s Path2Zero project in Fort Saskatchewan, Alberta.


Worley has recently been selected by Dow to provide front-end engineering and design services for the plant under a new EPCM contract for the cogeneration component of the project.


Dow’s Path2Zero project aims to create the world’s first net-zero emissions integrated ethylene cracker and derivatives site with respect to Scope 1 and Scope 2 emissions. Worley’s scope includes a brownfield installation of the cogeneration facility with integrated post-combustion carbon capture, which is expected to be operational towards the end of 2030.


Path2Zero is a flagship project for Dow, aiming to decarbonise 20% of Dow’s global ethylene capacity and triple the site’s polyethylene output.


The work will be carried out by Worley’s Canada and India based delivery team, supported by the company’s global network.
