I have already replied, reminding them of IES.
Alfa, I got an email from the Faversham Society containing a public notice asking for help from anyone with knowledgeable about batteries. I assume from that that they mean VRFBs as their next move is to try to get the currently proposed Lithium ones changed to VRFBs.
Thank you for that, I was wondering if they were using incorrect figures to back the environmental impact claim.
CowboyInvestor - I would guess that they simply got the amount of Vanadium Pentoxide confused with the amount of Vanadium.
8275 tonnes of V2O5 would be 4634 Tonnes of Vanadium - at 4,500 TonnesV per GWh this would equate to close to 1GWh energy storage. It is not clear what energy capacity the Cleve Hill battery is but if it is 350MW then 1GWh seems like it might be reasonable.
Lindon, thank you for your reply. Would you say the figures provided in the document are incorrect? They have quoted 8275 tons for a 350MW battery. This would need to be over 1.5GWh then?
CowboyInvestor, my understanding is the ratio of 5, 000 tons of Vanadium per GWh (don’t forget the ‘h’ ) was superseded by BMN higher graded mixed version to a presumed 4.5 tons per GWh. The V only accounts for around 8% the total mass of electrolyte that’s required per GWh.
Good job YTSS. Thanks for doing all that on our behalf.
pretty sure Cleve Hill is Lithium batteries
I am pretty sure Cleve Hill project as one of the Faversham called me a week or so ago. They knew the project would be signed off. Now they are going to try and stop the use of Lithium batteries. I had an email this morning asking for more details on battery technology etc, which I passed onto our resident expert. I have also passed on details of Invinity and BE - websites etc which showcases the technology etc
'Using the same approach, it can be calculated that approximately 8,275,540kg (8,275tons) of vanadium is dissolved in the 45,500,000 litres (45,500m3) of electrolyte solution considering 1 Mole vanadium (i.e 181.88g vanadium per litre) for the 350MW system.'
I thought it was 5000tons for 1GW?
I believe it’s a positive that the final choice of BESS is not decided as Li was originally favoured. However, the comments on RES5-34 would appear to relate to battery and solar panel decommissioning issues. It’s not clear - although the title relates to VRFB there is no link to suggest that he’s not referring to Li - confusing!
Any comments on 8.7.58 and also REP05-034?
Investigation report. Very lengthy but skip to battery section and you will find that it kicked the choice of battery into touch.

Media Report:
Britain’s largest solar farm, with almost 900,000 panels generating enough power for 91,000 homes, is to be built in Kent after the government dismissed concerns about its effect on the countryside.
The developers promise that the £450 million Cleve Hill solar farm, approved yesterday by Alok Sharma, the business secretary, will operate without subsidy and help Britain meet its climate change targets.
The 350-megawatt farm, which is five times bigger than the largest current solar farm, Shotwick in north Wales, will involve covering 436 acres of fields on the north Kent coast with panels, some of which will be built on steel frames almost the height of a double decker bus because of the flood risk.
The total area of the development near Faversham is 958 acres and may include one of the world’s largest batteries to store solar power and help meet peaks in demand.
The project has divided environmental groups, with Friends of the Earth welcoming the project but the Campaign to Protect Rural England (CPRE), Kent Wildlife Trust and the RSPB opposing it. Helen Whately, the Conservative MP for Faversham and Mid Kent, also opposed the development, saying it would have a “devastating” impact by “industrialising” the countryside.
Just saw this, haven't look to see if it's already been shared on this board.
