Subsurface Storage

Spindletop spin-off: Helium storage

Qatar, generally responsible for a third of global helium supply, has had to halt production because the Iran war prohibits export. Storing liquified helium gas at surface is not cost-effective; highly specialised, insulated tanks are needed, and even then, the…

Many CCS projects may falter quietly without the promised benefits

In a recent special issue of EAGE’s journal First Break, dedicated to underground storage, one finds the usual articles that one would expect for such a publication. But there happened to be one little outlier. Or maybe a slightly larger…

Storing heat in basement rocks

“Having a look at our lineament map,” says Jon Engström from the Geological Survey of Finland, “that is the first thing you need to do when you’re planning a subsurface project in our country.” Jon is a structural geologist who…

The CCS parallel universe

Sometimes, I cannot prevent the feeling that the CO2 storage business is not so much about putting CO2 in the ground, but rather to keep an entire academic research community, a conference industry, and a contingent of geoscientists in a…

The subsurface is a key factor in explaining the poor result of the recent Danish CCS tender

Denmark is one of the countries that aims to be a leader when it comes to climate change mitigation measures. That’s why the government launched a tender process in October 2024 for businesses to apply for a juicy pot of…

Carbon capture and mineralisation pilots in the Middle East

44.01 named their company after the mass of the molecule that is central to their business: Carbon Dioxide. They use CO2 captured from industry or the atmosphere and dissolve it in water to create a carbonated injection fluid, a kind…

Diverting the flow: The hidden power of overburden barriers

Since Mark Lakos joined Rock Flow Dynamics (RFD) from Wintershall Dea a bit more than a year ago – a job that brought him to Russia and Egypt – he has been heavily involved with modelling of CO2 injection and migration…

Offshore Algarve Basin geological carbon storage potential

In the Algarve Basin, two late Miocene plays have been identified southeast of the Faro Peninsula using high-quality seismic and borehole data (Figure 1). These comprise of high-porosity turbiditic sands of Tortonian and upper Messinian age, overlain by regionally extensive,…

How can we monitor North Sea carbon stores under wind farms and production platforms?

Repeat time-lapse seismic surveys can track CO2 plume migration, but where the seabed is obstructed by wind turbines or oil and gas platforms, access by vessels towing long multi-streamer arrays is impractical. Research in the Centre for Energy Transition, part…

“In one year, we lost two years”

“Last year was not a very good one,” Habib admits when we meet on Teams. “Everybody expected that 2025 would be a turning point in the market, with many projects coming online. But unfortunately, that did not happen. And if…

Silver out, air in

Just as Aberdeen in Scotland – where this article was written – is sometimes referred to as the “Silver City”, the village of Broken Hill in southeastern Australia is described in the same way. But where in Aberdeen this nickname…
