Could Highview Power’s Batteries Be Used Offshore?
When I first saw Highview Power’s Liquid Air batteries or Long Duration Energy Storage (LDES), I liked them.
This was partly because I’d investigated large tanks for chemical reactions and I like their mathematics.
But it was mainly because the concept had been developed by a lone inventor in Bishops Stortford.
In Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?, I bcalculated, that a 5,000 cubic metre tank could hold about a GWh of electricity as liquid air.
So just as steel and concrete tanks were placed on the sea floor to hold oil and gas, could they be placed on the sea floor to hold compressed air?
I don’t see why not!
I suspect, that it’s all fairly standard offshore engineering.
If you want more storage, you would just add more tanks.
Could They Be Combined With Electrical Substations?
I don’t see why not!
There may be advantages with respect to safety and noise.
The Anonymous Widower 
NESO in freezing the connection queue have identified that short term storage ie batteries is way over subscribed and are signalling they will be pushed down the queue (they don’t want to force cancel them but let the promoters see they will have to wait too long and cancel them themselves). Long Term storage remains a significant risk to getting to NZ2030 and that will require the retention of gas fired stns at considerable cost over 3B pa through the capacity mkt. Last 10yrs govts have continued to chuck money at Fusion and Hydrogen but its about time Long Term storage had a support mechanism so these sort of projects can be bought on line at scale far quicker.

The underlying technology of Highview Power, is all well proven and they have run a small demonstration plant at the Pilsworth Landfill in Bolton for two years and now they have the backing of four of the biggest beasts in the City, I feel they will start to get the Carrington and the other four plants up and running.
I suspect their biggest problem will be to convince Ed Miliband, that an idea thought up in a shed in Bishops Stortford is worthy of consideration.
