Weyburn-Midale, US/Canada

The Weyburn-Midale project is a uniquely international demonstration of CCS. CO₂ is captured from a coal-gasification plant in North Dakota in the United States. The captured CO₂ is then transported 320 km via pipeline, across the border into Saskatchewan, Canada, where it is used for Enhanced Oil Recovery. 2.8 million tonnes of CO₂ are captured and injected per year.

In Salah, Algeria

The In Salah Gas Project began capturing and storing 1 million tonnes of CO₂ per year in 2004. CO₂ is captured at a natural gas processing facility and stored in a geological formation 1.8 km below the Sahara desert. The project is expected to store over 17 million tonnes of CO₂ over its lifetime.

Sleipner, Norway

The world’s first commercial CCS project, the Sleipner project is operated by Norwegian oil and gas company, Statoil. It has been capturing and storing 1 million tonnes of CO₂ per year since 1996. The Sleipner project captures CO₂ from natural gas extracted from the offshore Sleipner gas field in the North Sea and re-injects it into the Utsira saline formation a kilometer below the sea floor.

Snøhvit, Norway

The Snøhvit project captures CO₂ at a liquefied natural gas (LNG) facility near Hammerfest, Norway. CO₂ capture is necessary for LNG production and the captured CO₂ is piped offshore and injected into a sandstone formation 2.6 km below the sea floor. The project began in 2008 and is capturing 700,000 tonnes of CO₂ a year.

GreenGen Project, China

The $1 billion Greengen project in China is being developed to stem the increase in CO₂ emissions forecast to come from its continued coal-driven economic growth. Unlike the four fully functional integrated plants above, Greengen is Asia's premiere demonstration project with construction having begun in 2009.

China has the world’s largest coal reserves and the world’s largest energy growth rate, 70% of which is fueled by coal. Furthermore, Chinese coal-fired power plants are less efficient than elsewhere in the world. As the world’s biggest produce of CO₂ emissions already, the need for carbon sequestration is evident.

Located in the port city of Tianjin, Greengen will employ Integrated Gasification Combined Cycle (IGCC) technology in a 250 MW powerplant. As the project develops, CO₂ capture will be introduced to a 650 MW plant, targeted for 2015.
