Hey! A short intro; I'm Conor, a geologist working across the energy industry, including CO₂ storage (both #CCS and #CDR), H₂ storage and radwaste disposal. I've published papers focused on offshore Ireland (some example figs below) which you can check out here: scholar.google.com/citations?us...

Ireland has great potential for in-situ CO2 mineralisation. However, policy roadblocks must be overcome to unlock these resources, ensuring the country reaches its #EU-mandated emissions targets. Read the paper, share your thoughts, and lets collaborate!

When it comes to public perception and social license, it's not as simple as 'offshore is easier'. A review of published studies shows that considerate stakeholder engagement, throughout project development, is the best approach.

Offshore reservoirs offer much larger storage volumes, but are often in more challenging operating environments, increasing exploration and development costs, roughly by an order of magnitude. Both offer large storage volumes for both #CCS and #CDR.

Really excited to share our latest publication! We investigate two basalt layers in #Ireland to compare the technical, economic, and social aspects of in-situ #CO2 mineralisation offshore and onshore! Read the accepted post-print at the link below: www.lyellcollection.org/doi/epdf/10....

BGS has launched the UK Geothermal Platform, which provides national- to local-scale information on geothermal potential.

Geothermal technologies have the potential to decarbonise heating and cooling, supporting the energy transition to net zero in the UK.

The graphic shows an illustration of a computer screen, with a map of the UK on it, and to the left are the layer controls. Above it says in blue text 'UK geothermal platform'.

Why Northern Ireland is a 'Goldilocks' area for renewable home heating

“Wait,” I said, before clicking the link. “What does Google have to do with earthquake emergency alerts in Turkey?”

spoiler alert the answer is “giving us all a haunting glimpse into the privatization of science and emergency management”
Google failed to warn 10 million of Turkey earthquake severity
The tech giant said only 469 serious warnings were sent out ahead of the 7.8 magnitude quake.

This core from well 53/04a-9 is from the southern margin of the SPB, where the Zechstein evaporite succession has a limited thickness.

The wellsite geologists have attempted to interpret the classic Zechstein formation breakdown, but isn't it a challenge to recognise the Grauer Salzton in here?

Check out my second Geostorage Insights article over on Substack! We explore the trapping mechanisms keeping #CO2 underground, consider how long we need to keep it safe, and explore #MRV and look at case studies of successful #CCS and #CDR projects!

“This paper presents a bold proposal to employ a buried nuclear explosion in a remote basaltic seabed for pulverizing basalt, thereby accelerating carbon sequestration through Enhanced Rock Weathering (ERW).”

Or, we could just stop burning fossil fuels🤷🏻‍♂️
