We can proudly state that Tailwater Technical Consulting (TTC) has design, commissioning, and operating experience with intricate details of CO2 (GHG or Carbon as sometime referred) capture from processes. This process is followed by a purification step, including dehydration, and followed by compression. The purpose of sequestration could be EOR (Enhanced Oil Recovery) or hundreds of years of delayed GHG impact.

“While numerous EPC companies talk about this subject, there are only a handful of design and implementation projects in the world. We highly recommend operating companies choose your Carbon Capture and Sequestration (CCS) partner with rigor of actual experience”

At Tailwater Technical, we are your complete solutions provider for carbon capture and sequestration. We provide engineering and project management services from concept to completion of the project. We have extensive knowledge and hands-on experience with dehydration and amine systems which are key components of a successful CCS designs and implementation. We have project management capabilities that allow us to support our client with the full cycle of their project. We have engineering and project management strength with 15-25 years of experience, who are well versed in using these tools for making decisions.

FAQs – Carbon Capture & Sequestration

A: Carbon Capture, Utilization and Storage (CCUS) is a set of technologies that capture carbon dioxide (CO2) emissions at source, preventing them from entering the atmosphere, or else directly from the air. The CO2 emissions are then transported away and either stored deep underground or turned into useful products.

  • Capture is the process of capturing CO2 from exhaust or reformed gases or stationary sources, using technologies categorized under pre-combustion, post-combustion or oxy-combustion.
  • Sequestration is the process of depositing the captured CO2 in geological formations.
  • Utilization is the direct use of captured CO2 (for example in cement) or the conversion of captured CO2 and other gases into useful industrial products, such as chemicals or fuels.
  • Mobile Carbon Capture technology can capture CO2 from mobile sources and store it on board, ready to be taken away for sequestration or utilization.
  • Direct Air Capture is the process of capturing CO2 directly from the atmosphere (rather than at source) and remove CO2 to be sequestered or utilized.
  • Oxy-combustion is a technology that uses pure oxygen to combust fuels, increasing combustion efficiency and increasing the concentration of CO2 in flue gases, enabling easier CO2 capture.
  • Bio Energy Carbon Capture and Storage (BECCS) uses CCS technology to extract and store CO2 from biomass, itself a renewable energy source.
  • Nature can act as a natural carbon sink, such as mangrove trees which sequester carbon far more effectively (up to 100 times faster) and more permanently than terrestrial forests.

A: CCS has the potential to significantly reduce greenhouse gas emissions by removing large quantities of CO2 that would normally be released into the atmosphere and instead storing it deep underground.

A: Many of the CCS technologies used are well developed and have been used for decades by the petroleum industry. Experience with geological storage projects across the world has also shown that CO2 can be stored securely with a very low risk of leakage. 

A: CO2 is a naturally occurring gas that is released into our atmosphere every day from respiration by all animals, fungi and microorganisms. We breathe it out, plants use it as a part of photosynthesis. It is not toxic, flammable or explosive. In fact, low levels of CO2 are necessary for all life. CCS involves storing large quantities of industrially produced CO2 deep underground in naturally occurring geologic formations. 

A: Effective January 2021, Section 45Q of the Tax Code provides tax credits for capturing and sequestering carbon oxides that would otherwise escape to the atmosphere and contribute to climate change. Those involved with a broad range of carbon capture projects and technology can now claim tax credits under Section 45Q of up to $50 per ton of carbon captured and placed in secure geological storage, and tax credits of up to $35 per ton of carbon injected into oil or natural gas wells for enhanced recovery (EOR).

A: Class II wells are used exclusively to inject fluids associated with oil and natural gas production as well as injecting CO2 for Enhanced Oil Recovery (EOR). Class VI are wells used for injection of carbon dioxide (CO2) into underground subsurface rock formations for long-term storage, or geologic sequestration.

A: The success of the rapidly growing number of carbon capture projects hinges on the ability to timely obtain a single permit – the Environmental Protection Agency’s (EPA) Underground Injection Control (UIC) Class VI permit.

A: The carbon dioxide levels in the atmosphere – and how to reduce them – is a daunting and pressing problem. Carbon capture and storage (CCS) has long been seen as one technology with the potential to reduce GHG emissions significantly. For companies to work with and achieve climate goals, carbon capture and storage technology must be mainstreamed.

A: As CCS is a new industry, initial costs will be high. However, future costs are likely to decline with advances in technology and once it is used on a large-scale. In terms of power generation, estimated costs for using CCS technology are comparable to other low emission technologies such as wind, and significantly cheaper than solar.

A: CO2 can be stored in geological rock formations deep underground. There are currently three main storage options: 1) depleted oil and gas fields, 2) deep saline aquifers and, 3) coal seams unsuitable for mining. Suitable storage sites must be at a depth of at least 800 meters so that the pressure and temperature is high enough for the injected CO2 to remain in a dense, fluid-like (or supercritical) state.
