Norwegian energy company Equinor announced plans with its partners to disclose datasets from the Sleipner offshore carbon capture and storage (CCS) plant, in an effort to advance development and innovation in the field of CO2 storage.

The Sleipner field is the world’s first offshore CCS plant and the longest ongoing CO2 storage project in the world, having been in operation since 1996. The field captures about a million tonnes of CO2 from natural gas per year, which according to Equinor provides “unique insight” into the effects of underground carbon storage for longer periods of time.

Equinor senior vice president and chief digital officer Torbjørn F. Folgerø said: “For over 20 years we have had a first-hand experience of safe storage of CO2 in a reservoir.

“We believe this insight can be valuable for both our industry, research communities and others working on making CO2 storage a central part of the ongoing energy transition into the low carbon future.”

The data will be published via a CO2 Data Share Consortium led by Norwegian research organisation SINTEF in September 2019. This partnership is supported by the US Department of Energy and Norwegian CCS research programme CLIMIT.

SINTEF executive vice president Eli Aamot said: “Ever since Equinor shared the first Sleipner datasets, researchers across the world have used it to understand flow processes, enable more accurate predictions and develop methods for safe CO2 storage.

“Access to the Sleipner datasets can accelerate the development of knowledge and technologies essential for operating CO2 storage sites and enable faster deployment of CCS, a measure The Intergovernmental Panel on Climate Change (IPCC) states is critical to limit the global warming.”

A prototype for the data sharing will be available online for selected test users in June 2019, with a digital platform for sharing CO2 data expected to come online in September 2019.
