Jonathan Alexander

Postgrad researcher @LivUniEarthSci focussing on the potential of mineral carbonation in Northern Ireland's basalt for CO2 storage. Graduate of @GeologyLeics.

Just as I read about Li-Cycle in 'The War Below' by @ErnestScheyder, which discusses (amongst other things) the need for critical metals for the green energy transition (I definitely recommend to Geologists), Google coincidentally tells me this sad news...

@Liam_Geochem Exciting stuff, best of luck!

[Jonathan Alexander @geo_jonno]

I thoroughly enjoyed presenting some of the results from my MSc research at the #IGRM24. It was great to meet/catch up with everyone!
I was also delighted to have been one of the Barry Long Prize recipients, second place, for my talk, awarded by @IrishGeologic, I'm very grateful!

A clearer view of part of the Lough Fee ultramafic intrusion, in Ireland. Lighter bands are clinopyroxene, and the darker bands are serpentine. Much credit to @BODriscollEarth for his 2005 paper covering this outcrop and intrusion!

Geological sightseeing in Ireland, hiking up Garraun with the @uniofgalway Mountaineering Club. Highlights include some impressive boulder conglomerate from the turbiditic Lettergesh Formation, and the wonderful layered ultramafic intrusion of the Lough Fee Peridotite.

[Jonathan Alexander @geo_jonno]

Some of the largest clasts I've ever seen in a conglomerate (Lettergesh Fm, Ireland). #Geology

Beautiful serpentinite

Great to see some new research from Canada's @solid_carbon team!

[UniversityOfVictoria @uvic]

New research from @solid_carbon shows it's safe to store CO2 in ocean basalt rock.

The #climatechange mitigation project is led by @Ocean_Networks, a #UVic initiative, & funded by @PICSCanada.

@AndreasenJack See, I'd have suggested 'carbon mineralization', but that wouldn't include the likes of Hyrogas, CTSCo, Core Energy.. which I gather are still far from that

[Jonathan Alexander @geo_jonno]

@AndreasenJack @CarbonRemover @_david_ho_ It's a number interdependent on current emissions. It isn't fixed. His analogy just shows that CDR is more effective in a world with less emissions (as I'm sure you're aware!) 2 hours compared to 13 minutes is a huge difference, and scales up.

[Jonathan Alexander @geo_jonno]

@AndreasenJack @CarbonRemover @_david_ho_ Those theoretical ‘3 seconds’ (in the case of CDR) will amount to far more as we phase out fossil fuels and decarbonise sectors. It isn’t a fixed number.

[Jonathan Alexander @geo_jonno]

@AndreasenJack @CarbonRemover @_david_ho_ Not a great comparison because wind and solar projects are directly replacing fossil fuels, to produce needed electricity, and slowly beginning to compete with non-renewables (economically).
The point is, the lower our total emissions, the greater CDR's impact is.

[Jonathan Alexander @geo_jonno]

@AndreasenJack @CarbonRemover @_david_ho_ Not sure what you mean.
I don't think it's discouraging CDR deployment, but instead highlighting the importance of decarbonisation in amplifying CDR efforts. By exhausting cheaper and more impactful forms of decarbonisation, removals from installed CDR will be more meaningful.

[Jonathan Alexander @geo_jonno]

@AndreasenJack @CarbonRemover @_david_ho_ I imagine MRV difficulties, scalability and land use could refer to afforestation. Or more likely, OAE still needs to overcome marine environ issues, energy use from excavation (if not tailings) and crushing, + major MRV issues.

Not sure what's wrong with the time machine tweet?

[Jonathan Alexander @geo_jonno]

@marcreichow Awesome news! Very well deserved!! 🍾

[Jonathan Alexander @geo_jonno]

@DrSadhbh @EthanRockStory Woah! I had this book in my house and remember that Blue John page very well. Also the page on asbestos fire suits, and the really lovely images of agate.

[Jonathan Alexander @geo_jonno]

@edda_ara @JustinTrudeau Any mention of the Canadian Solid Carbon project led by Ocean Networks Canada? If CO2 mineralisation with seawater is demonstrated by CarbFix at Helguvik, there might be potential collaboration with their offshore Cascadia Basin project.

[Jonathan Alexander @geo_jonno]

@seis_matters Those are glorious 🙌

[Jonathan Alexander @geo_jonno]

Presumably magnesite veins, and lots of them, indicating natural carbonation within the Lizard Complex peridotite!
