NL offshore has all the geologic requirements needed for safe CO2 storage as demonstrated by a long history of storing hydrocarbon gas within the reservoirs.
A future technical storage assessment by OilCo will add much‐needed quantification to the perceived CO2 storage opportunity in Newfoundland and Labrador’s offshore.
Project
Roadmap
CCUS has the potential to significantly reduce emissions in the NL offshore in the near to medium term should technical advances continue at their current pace. This will require concerted research and development effort as CCUS has never been applied in an offshore context before.
Timeline
Offshore Atlantic Canada has extensive expertise in offshore project execution, from engineering to fabrication to installation.
The CCS roadmap projects significantly more time is likely to be spent on regulatory and legislative development than project execution.
15 Years
Legislation
Determination of who owns and regulates pore spaces in offshore NL
Establishing who owns and regulates the pore spaces for CO2 storage is foundational for CCS development. Pore spaces refer to subsurface geological formations that can securely store CO2. Offshore Newfoundland and Labrador (NL) falls under federal and provincial joint jurisdiction as governed by the Canada-Newfoundland and Labrador Atlantic Accord Implementation Act.
- Current Status: Ownership of these subsurface resources is not explicitly defined, leading to potential regulatory and legal uncertainties.
- Next Steps: Clarify ownership and control mechanisms to define responsibilities for site access, storage rights, and liability management. This involves legal interpretations of the Atlantic Accord and may require legislative amendments or new regulations to ensure compliance with federal and provincial laws and international CCS standards.
Atlantic Accord Amendments
Federal & Provincial
The Atlantic Accord, originally focused on oil and gas activities, was amended in 2018 to regulate air emissions in offshore areas. These amendments provide a legal basis for CCS projects but do not yet fully address the specific requirements for CO2 injection and long-term storage.
- Importance for CCS: Without explicit provisions for CCS, project proponents face regulatory uncertainty. Detailed amendments must specify CO2 storage as an allowable activity, clarify the regulatory framework for such operations, and harmonize federal and provincial responsibilities.
- Action Plan: Propose further amendments to the Accord to integrate CCS-specific provisions. These should outline criteria for site licensing, environmental impact assessments, and operator liability. Cooperation between federal and provincial governments will be crucial to finalize these amendments, ensuring they align with international best practices and policies under agreements like the Paris Accord.
Storage and Injection Regulations
Developed by CNLOPB
The Canada-Newfoundland and Labrador Offshore Petroleum Board (CNLOPB) is the regulatory body for offshore oil and gas activities, and it needs an expanded mandate to regulate CCS storage and injection. This expansion would cover CO2 injection into geological formations and long-term storage to ensure environmental safety and compliance.
- Components of Regulation:
• Site Characterization: Regulations should include comprehensive geological surveys to identify suitable storage formations.
• Injection and Monitoring Standards: Develop operational standards for CO2 injection, plume tracking, and pressure management to mitigate risks.• Risk Management and Emergency Protocols: Include requirements for risk assessments, contingency planning, and emergency response mechanisms in case of CO2 leakage or other incidents.
• Environmental Compliance: Establish stringent monitoring, measurement, and verification (MMV) requirements to ensure that CO2 remains securely stored.
- Implementation: CNLOPB can collaborate with industry experts and global CCS leaders to draft these regulations. Piloting regulatory processes on smaller-scale projects will help refine the framework before widespread adoption.
Licensing
Board led call for information, Call for bids, Land issuance
A structured licensing process is needed to facilitate private sector participation and investment in CCS. This would mirror existing oil and gas licensing systems, involving a call for information, bid submissions, and land issuance for potential CO2 storage sites.
- Steps in Licensing:
• Call for Expressions of Interest: CNLOPB invites stakeholders to provide data on potential CCS opportunities and areas of interest.
• Site Evaluations: Conduct geological and environmental assessments to identify suitable storage areas with high CO2 containment potential and low environmental risk.• Bid Solicitation: Open competitive bidding for licenses to explore, develop, and operate CCS sites.
• Land Issuance: Award licenses for CCS operations, with conditions tied to performance, environmental compliance, and ongoing monitoring.
- Long-Term Benefits: This approach ensures a transparent, competitive process that attracts industry expertise and capital. Additionally, it aligns with CNLOPB’s mandate to manage resources responsibly and optimize economic and environmental outcomes.
Impact Assessment / Site Assessment
Project application submission
Before CCS projects can proceed, they must undergo a formal regulatory review to assess environmental, technical, and geological suitability.
- Process:
• Environmental & Geological Assessments: Evaluate site integrity, CO₂ containment security, and potential risks to marine ecosystems and groundwater.
• Public & Indigenous Consultation: Gather stakeholder input to address concerns and incorporate local knowledge.• Regulatory Submission: Project proponents submit applications detailing site assessments, risk management, and compliance measures.
Projects meeting initial criteria advance to the decision stage for formal approval or rejection.

NL Offshore Installation Implications
Even though post‐combustion carbon capture may be considered the most feasible capture technology option for offshore NL, it has many challenges for offshore implementation. While it may be one of the relatively lower cost technologies to capture emissions from turbine exhaust, it still remains a high‐cost endeavor on
an absolute basis.
Environmental
Carbon Capture technology is that it introduces potentially new chemicals into the offshore environment that are used for CO2 absorption. These new chemicals may complicate the offshore processes.
Safety
CO2 is an inert gas and will not present a fire risk to a platform. However, CO2 is toxic at high concentration and will also cause asphyxiation if oxygen concentrations are too low.
Regulatory
The project would almost certainly result in a development plan amendment involving the regulator and statutory certification. Downtime and deferred production would need to be considered in the economics of the project.
Space and Weight Constraints
A critical balance would need to be found between the target carbon capture efficiency, available space, weight considerations, and electrical power demands.
