Embarking on a Carbon Capture, Utilization, and Storage (CCUS) project is a significant step towards environmental stewardship and regulatory compliance. The journey begins with an understanding of the various aspects of carbon management, including the capture, conversion, and repurposing of CO2, as well as exploring alternatives to reduce greenhouse gas emissions.

Navigating the complexities of regulations, funding, partners, and technical requirements can be significant. To start, one must consider several critical questions: How will the captured CO2 be used or stored? Is there a suitable sequestration site and nearby infrastructure? What are the options for utilization? How will the project be funded, and can you leverage tax benefits like the IRA's $85 per tonnes incentive? Additionally, assessing the impact on the existing facility's steam source, availability, and power consumption is essential.
The most effective approach to assess feasibility is initiating a Pre-FEED (Front-End Engineering Design) or Conceptual Engineering effort. This preliminary stage includes feasibility studies, technology selection, process design packages, heat and material balances, PFDs/P&IDs, and equipment design. The goals of Pre-FEED is to define the project scope, develop cost estimates, identify risks, and develop project schedules.

Following Pre-FEED, a Front-End Engineering Design (FEED) study provides a detailed evaluation of the project scope, cost estimate, risk, and schedule, ultimately leading to a decision on whether to proceed. The full engineering design phase that follows FEED involves finalizing documentation for construction, detailing piping isometrics, utility systems, mechanical datasheets for equipment, civil/structural design, and equipment procurement.

After the engineering and planning phases, the project moves into construction, installation, commissioning, and start-up. This structured approach ensures that every aspect of the project is considered, paving the way for successful and sustainable operations.
Toshiba has supported various CCUS plants and initiatives. The most notable, the Mikawa Post Combustion plant,* is a testament to the company's commitment to Carbon Capture, Utilization, and Storage. With the capability to capture over 600 tons of CO2 daily, which accounts for more than half of the plant's emissions, Mikawa serves as a model for efficiency and innovation. The plant's extensive experience, amassing nearly 13,000 hours, has been crucial in refining CCUS processes. Toshiba's broader efforts include R&D, plant design, and deployment of advanced CO2 capture technologies, such as Amine solvent solutions and P2C technology, reinforcing its dedication to a low-carbon future.
