Carbon Capture & Storage

Understanding CO2 flow at Sleipner using stratigraphic continuity

Basil Onyekayahweh Nwafor and John Castagna, University of Houston, Robert Van Eykenhof and Marianne Rauch, Lumina Geophysical
The Sleipner pro­ject, located off­shore Norway, marks one of the first large-scale carbon cap­ture and storage (CCS) in­itiatives. Since 1996, more than 18.5 million tons of CO₂ have been injected…

Keeping geoscientists busy

Henk Kombrink
Geoscientists can go too far in the relent­less pursuit to de-risk all elements that could cause a CO2 store to leak. At least, that is my take based on listening…

Creating a source rock and storing it for good

Henk Kombrink
“We started as a project when Swiss supermarket concern Migros wanted to find a solution to process its food waste in a carbon-neutral way,” says geologist Tim Baars from Recoal.…

Basalt as a CO2 storage reservoir

Lois Greenfield, Aberdeen University
Harnessing a natural process, mineralization of CO2 is the pro­cess by which primary and secondary minerals such as Mg, Fe, and Ca pres­ent in basalts interact with CO2-enriched fluids to…

The injected CO2 that went missing

Henk Kombrink
It is always good to speak to people at con­ferences and hear what is going on. That is how I learned about a CO2 storage project that took place in…

3 million versus 100 k

Henk Kombrink
Once large-scale CO2 injection projects will hopefully ramp up, monitoring injection will be an essential part of the work­flow. And because the carbon storage business will never be a commercial…

A leak – but what next?

Henk Kombrink
The E&E News website, part of Politico, recently published the news that the US Envi­ronmental Protection Agen­cy (EPA) issued a violation notice to the operator of the Decatur CCS pro­ject…
