Lead consultant geo exploring underground for safe and durable storage for CO2 ☁️, H2 🔋, and radwaste ☢️! 🇮🇪 🇵🇹 🇪🇺
Pinned
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...

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.

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?
