The Alberta Carbon Grid™ (ACG) is a world-scale carbon transportation and sequestration system being designed to serve multiple customers, industries, and sectors. Once fully constructed, the ACG aims to transport and sequester up to 20 million tonnes of CO2 annually – almost 10 per cent of Alberta’s industrial emissions and has an important role to play to support Alberta’s lower-carbon economy.

About the
Project

A collaboration between Pembina Pipeline Corporation and TC Energy, the Alberta Carbon Grid is an open-access system intended to serve as the backbone for Alberta’s emerging carbon capture utilization and storage (CCUS) industry, connecting key sequestration locations and delivery points across the province to serve multiple industries. When fully constructed, the system is designed with the potential capability of transporting and sequestering up to 20 million tonnes of CO2 annually, which would be equivalent to removing 7.5 million cars off the road each year.

In February 2022, we submitted an application to the Government of Alberta to build and operate a carbon storage hub and gathering lines in the industrial heartland near Edmonton. In March 2022, the Alberta Government confirmed that the ACG has been invited to move forward into the next stages of the province’s CCUS process to further evaluate the suitability of the proposed location for safely storing carbon from industrial emissions.

We are excited about the opportunity to work alongside the Government of Alberta, collaborate with our industry peers, and connect with Indigenous communities and key stakeholders to advance this important work. The project is part of a multi-year effort to help meet federal emissions targets and benefit the Alberta economy. CCUS is an essential step in decarbonization and reducing GHG emissions to help meet Canada’s climate goals.

The Alberta Carbon Grid is part of Pembina’s and TC Energy’s ongoing commitment to energy diversification, industry collaboration, and a lower-carbon future that benefits the environment and the Alberta economy.

Carbon
capture, utilization, and storage 101

For many, carbon (CO2) capture, utilization, and storage (CCUS) is a new concept, but CCUS has been around since the 1970s using similar technology and operations to oil and gas pipelines. Learn about some of the most asked CCUS questions below:

What is CCUS?

CCUS is the process of capturing CO2 from industrial emissions so that it isn’t released into the atmosphere. CO2 can be moved to an underground storage (sequestration) area or can be ‘utilized’ to help make fuels, chemicals, or materials such as concrete and fertilizer, or in processes like enhanced oil recovery.

Why is CCUS important?

CO2 is a greenhouse gas linked to global climate change and removing it from the atmosphere can help slow climate change. CCUS will play a vital role in helping Canada achieve its enhanced climate targets, including a 40 – 45 per cent reduction in greenhouse gas emissions, based on 2005 levels, by 2030.

Can CO2 that is stored be utilized later?

No, once stored underground, CO2 will remain there permanently. Sequestration is located in large geological formations deep underground. In Alberta’s case, the formation is over two kilometres beneath the surface.

How is CO2 captured?

There are several ways that CO2 can be captured, including solvent based technologies, physical membranes/filters, and absorbents. Alberta Carbon Grid (ACG) industrial customers will capture CO2 from their facilities before being transported by ACG pipelines to a sequestration reservoir. The CO2 will be converted from a gas into a liquid before being transported because more CO2 can be transported in liquid form than in a gas form.

Where can CO2 be stored?

CO2 can be stored in any location with the right geological conditions. Currently, the Government of Alberta will only grant permission for CO2 storage within crown land.

Can stored CO2 be released accidentally?

CO2 storage reservoirs are deep underground and geologically stable – meaning the reservoir formation has strong containment characteristics to prevent CO2 from escaping. Additionally, safety and environmental considerations drive both Pembina’s and TC Energy’s technical due diligence to support our current and proposed operations. All sequestration project regulatory approvals require that sequestration operators have an active and effective monitoring, measurement, and verification plan that ensures the CO2 is stored as intended.

Can stored CO2 impact groundwater sources?

No, underground storage for CO2 is much deeper than groundwater sources.

What role does ACG have in CCUS?

The ACG is designed to collect CO2 from multiple emitters and transport it to a sequestration hub(s) or utilization points. ACG is considering new assets, existing infrastructure, and a newly developed carbon sequestration hub to connect the province’s largest regions of industrial emissions – the Alberta Industrial Heartland, Edmonton-area, and the Drayton Valley region – to key sequestration locations. The ACG’s proposed sequestration reservoir can accept up to 20 million tonnes of CO2 in liquid form per year for decades.

The
Partnership

Pembina Pipeline Corporation (Pembina) and TC Energy Corporation (TC Energy) are working together to develop an open-access carbon transportation and sequestration system. Both companies have decades of experience in safe and reliable development, construction, and operations of infrastructure solutions with, and on behalf of, customers, investors, communities and employees. The ACG is part of Pembina’s and TC Energy’s ongoing commitment to energy diversification, industry collaboration, and a lower-carbon future that benefits the environment and the Alberta economy. We are excited about the potential to create an effective and strategic solution with and for these key stakeholders.
