I'm doing a site visit to some of the HS2 build on Tuesday, if there is any interesting engineering works going on I'll drop a picture in here Reets. For all its faults, its impressive stuff is the old HS2

Just got a leaflet through the post about a proposed project to install a pipeline from some cement production plants in Buxton area across Cheshire and through the length of Wirral out into the Irish Sea to store CO2 gas from the concrete plants.
They thing it might need a 300 meter wide channel to install the pipe line.
Consultation process to start soon.

It'll cause disruption while being done but once it's done, you won't notice. There's at least one one from Stanlow to Ringway airport . (That's manchester airfor the younguns)

I did a site visit to one of our HS2 sites, sadly we spent the day looking at the utility diversions, so a day spent looking at pipes in dirty ditches. We did pass a line of 50+ ADT dumpers layed up. A few quids worth of assests.

We passed an over bridge under construction, apologies for the crap pics, we had a line of 8wheel tippers behind us so could only slow a bit

I wonder what they're doing with it in the Irish sea. If its a matter of pumping it to depth and dissolving the CO2, then that causes acidification which starts to dissolve shells, (which also releases CO2) so I hope they've thought of something better! I had to teach about the pros and cons if that in A level chemistry 20 years ago.

Alright arch.

Alright c

Alright c

Hope you are well today sorry it is late.

Isn't there a chasm/abyss (yes there is, Beaufort's Dyke) where millions of tons of live ammunition was dumped after wwii. Seems the Irish sea has been treated as a privy for some time. (live ammo washes up on beaches to this day. someone run a st george up quick, makes you proud...)

That's the plan, capture the CO2 and pump it into storage.

Exactly what do they mean as storage?

If its an exhausted oil well (which i doubt) then fine.

If its deep sea* (cheap) its an unseen, quiet environmental disaster that will only become apparent to the public in decades (by which time the people running the scheme will have collected their millions and retired).

Britain .... Britain never changes.

*the only bit that's properly deep sea enough there is the channel @Rita_Poon mentioned... I suspect we will see the interaction between dumped munitions and acidified water a little sooner than the execs think!!

Will be a reused oil well or gas reservoir, think it's getting pumped around the Morecambe Bay area.

I know more about the North Sea plan.
