This List of carbon capture and storage projects provides documentation of global, industrial-scale projects for carbon capture and storage. According to the Global CCS Institute, in 2020 some 40 million tons CO2 per year capacity of CCS was in operation with 50 million tons per year in development. The world emits about 38 billion tonnes of CO2 every year, so CCS captured about one thousandth of the 2020 total.
Algeria
In Salah was an operational onshore gas field with CO2 injection. CO2 was separated from produced gas and reinjected into the Krechba geologic formation at a depth of 1,900m. Since 2004, about 3.8 Mt of CO2 has been captured during natural gas extraction and stored. Injection was suspended temporarily in June 2011 due to concerns about the integrity of the seal, potential for fracture and leakage into the caprock, and movement of CO2 outside of the Krechba hydrocarbon lease. Injection has not restarted and no leakage of CO2 was reported during the lifetime of the project
Australia
In the early 2020s the government allocated over A$300 million for CCS both onshore and offshore.
Canada
Canadian governments committed $1.8 billion fund CCS projects over the 2008-2018 period. The main programs are the federal government's Clean Energy Fund, Alberta's Carbon Capture and Storage fund, and the governments of Saskatchewan, British Columbia, and Nova Scotia. Canada works closely with the United States through the U.S.–Canada Clean Energy Dialogue launched by the Obama administration in 2009.
Alberta
Alberta committed $170 million in 2013/2014 – and a total of $1.3 billion over 15 years – to fund two large-scale CCS projects.
The CAN $1.2 billion Alberta Carbon Trunk Line Project (ACTL), pioneered by Enhance Energy, became fully operational in June 2020. It is now the world's largest carbon capture and storage system consisting of a 240 km pipeline that collects CO2 industrial emissions from the Agrium fertilizer plant and North West Sturgeon Refinery in Alberta. The capture is then delivered to the matured Clive oil reservoir for use in EOR (enhanced oil recovery) and permanent storage. At full capacity, it can capture 14.6 million tonnes of CO2 per year. For perspective, that translates into capturing CO2 from 2.6 million cars plus.
The Quest Carbon Capture and Storage Project was developed by Shell Canada for use in the Athabasca Oil Sands Project. It is cited as being the world's first commercial-scale CCS project. Construction began in 2012 and ended in 2015. The capture unit is located at the Scotford Upgrader in Alberta, Canada, where hydrogen is produced to upgrade bitumen from oil sands into synthetic crude oil. The steam methane units that produce the hydrogen emit CO2 as a byproduct. The capture unit captures the CO2 from the steam methane unit using amine absorption technology, and the captured CO2 is then transported to Fort Saskatchewan where it is injected into a porous rock formation called the Basal Cambrian Sands. From 2015 to 2018, the project stored 3 Mt CO2 at a rate of 1 Mtpa.
Entropy, a subsidiary of Advantage Energy runs a sequestration project at Glacier plant near Valhalla, Alberta, storing 0.2 MT of CO2 per year as of 2022.
In 2022, Alberta Energy granted 25 CO2 sequestration evaluation licenses covering a total area of 10 million hectares.
Saskatchewan
Boundary Dam Power Station Unit 3 Project
Boundary Dam Power Station, owned by SaskPower, is a coal fired station originally commissioned in 1959. In 2010, SaskPower committed to retrofitting the lignite-powered Unit 3 with a carbon capture unit. The project was completed in 2014. The retrofit utilized a post-combustion amine absorption technology. The captured CO2 was to be sold to Cenovus to be used for Enhanced Oil Recovery (EOR) in Weyburn field. Any CO2 not used for EOR was planned to be used by the Aquistore project and stored in deep saline aquifers. Many complications kept Unit 3 and this project from operating as much as expected, but between August 2017 – August 2018, Unit 3 was online for 65%/day on average. The project has a nameplate capacity of capture of 1 Mtpa. The other units are to be phased out by 2024. The future of the one retrofitted unit is unclear.
