Vast salt caverns designed to store hydrogen are to be excavated under Britain’s biggest former naval base as part of plans to bolster the country’s energy security.
Each the size of St Paul’s Cathedral, the 19 caverns will be dug under Portland Harbour in Dorset and filled with enough hydrogen to fuel a power station for days.
The hydrogen contained in the caverns will be reserved for emergency use and called upon when wind and solar farms are not generating enough energy to keep Britain’s lights on.
Claire Coutinho, the energy secretary, is said to have not only backed the scheme but also altered the Government’s hydrogen storage business policy to ensure it can secure taxpayer subsidies.
UK Oil and Gas (UKOG), the company behind the scheme, has said it will seek planning permission within months.
Stephen Sanderson, UKOG’s chief executive, has said he would make the application under the Government’s nationally significant infrastructure system, allowing it to bypass potential local opposition.
He said: “Portland Port is ideally situated for the construction of large salt caverns as it overlies a 450-metre thick, high-quality rock salt.”
Mr Sanderson added: “I have enjoyed one-on-one meetings with the three key figures from the Department for Energy Security and Net Zero, including Secretary of State Claire Coutinho, Lord Callanan, Minister for Energy Efficiency and Green Finance and Graham Stuart, Minister for Energy Security and Net Zero.”
Portland Harbour lies in Weymouth Bay on England’s south coast and was first used as a naval base in the 16th century by Henry VIII.
It was massively expanded last century to accommodate new steam-powered warships, eventually becoming one of the Royal Navy’s biggest bases until it was closed in 1995.
It remains one of the UK’s largest harbours and the training centre for the UK’s Olympic sailing teams.
The harbour’s anticipated new role storing hydrogen relies on a rock known as halite or rock salt.
A massive layer of this has been found two miles beneath the surface – where it has been buried for at least 200 million years.
Salt is highly soluble so the fact it has lasted so long shows the rock has no water running through it – making it highly stable and suitable for storing hydrogen.
Matt Cartwright, UKOG’s commercial director, said the caverns would be created by drilling wells into the salt and then injecting fresh water to dissolve the rock.
UK Energy Storage, a wholly-owned subsidiary of UKOG, will oversee the project.
Each cavern is set to be 85 metres in diameter and 90 metres high with a capacity of 320,000 metres cubed, which is roughly twice the volume of St Paul’s Cathedral.
UKOG is facing a series of controversies over its involvement with onshore oil and gas developments around the UK.
It currently has interests in five oil and gas fields within the Weald and Purbeck areas of southern England but its attempts to exploi

The article comes from the Telegraph of 30/06.
Makes me chuckle when you hear this shower harping on like salt cavern storage is some new concept.
It has been something done since the 1950's, not rocket science, and Storenergy spent around half a BILLION to create Stublach caverns in Cheshire, not sure how this shower could even afford the fencing for the site, nevermind the actual works to create the caverns, which takes some considerable time to circulate and dissolve the salts & circulate out to create them.
Just one of the grand master of disaster's pipe dreams to keep his lifestyle he is accustomed too.
Claire Coutinho, the energy secretary, is said to have not only backed the scheme but also altered the Government’s hydrogen storage business policy to ensure it can secure taxpayer subsidies.
Makes me chuckle when people talk about storing hydrogen. Where will it come from ? There will occasionally be some surplus electricty from renewables that could be turned into hydrogen but that will be used up in a few fish and chip shops locally. Given the gas demand these days is 4X in energy terms the electricty demand during cold weather there will be a huge energy deficit even if ALL electricty production was converted to hydrogen. We are living in fantasy land and clearly physics was an option not taken up by many in government!
I hope the journalist had a nice lunch as he swallowed wholesale SS's BS.
How's the hydrogen going to get to Dorset? Where is going to be used after it's been stored? Where is the financial backing for the scheme? None of these questions are addressed by the article.
I would much rather use electricity compared to gas for heating. Far cheaper than gas so I don't know why there are what you say 4 times the user in gas to electric
Rubbish.
Gas is much cheaper than electricity
From my last bill;
Gas - 5.69p/kWh
Electricity - 15.73p/kWh
Not quiet the latest prices, but GAS still wins out above all other heating options.
Efficiency is what they are selling heat source pumps on, but as ZXY notes, because the electric KW cost is 4X gas then it still loses out on cost. Gas wins every time until they can bring the retail price of electric significantly less than today.
Heating method Efficiency (%) Annual energy use (kWh) Cost (p/kWh) Annual bill
Gas boiler 95 11,500 6.04 £694
Heat pump 300 3,833 24.50 £939
Oil boiler 92 11,875 11.14 £1,337
Electric boiler 100 10,925 24.50 £2,676
It seems to me that the same alias Chucle Brother Trolls are out in force when any positive news is announced,what saddos!
Alan, I think I need to explain my 4x . At peak demand on cold days the energy transmitted by the gas network is four times the energy transmitted by the electricty network. The source of that information is ntional grid and it is from about 3 years ago but unlikely to have changed. People and in particular politicians just don't understand we cannot replace the energy from gas with energy from electricty , even with a bit of hydrogen thrown in. It will not happen by 2030 for sure.
Balanced viewer,
perhaps you could identify any supposed good news that has eventually happened?
The best so far is HH-1 which was going to produce 362bopd, with no mention of decline. It never averaged that amount and rapidly declined to averaging less than 100bopd.
Broadford Bridge - transformational, national importance - testing was dire, didn't get round to applying to redrill/retest, now planning for retention refused.
HH-2z - supposed to produce 720 to 1080bopd. It never did, overwhelmed by water production and is currently suspended waiting fo UKOG to be brave and convert it to an injector
Basur-3 - transformational target was missed as structure non existant
Pinarova - all sorts of claims, P&A'd after long delay.
All of these were supposed 'good news' when they were announced - only to disappoint or completely fail.
To criticise anyone that has previously been negative about supposed 'good news' suggests that it's you that's the troll.
LOL Penguins, When any Government gives a positive view on a future Green resource is very good news imo. I would suggest which ever Government backs Green projects will charge a levy to repay the Tax payer. Surely you don't think Ukog are going it alone do you.
Balancedviewer,
'“She was very supportive of our hydrogen storage project at Portland in Dorset,” said CEO Sanderson.'
........a few kind words of encouragement from a minister who's about to lose the job doesn't necessarily translate to any meaningful support for a project, though not sure what this sentence even means:- 'I would suggest which ever Government backs Green projects will charge a levy to repay the Tax payer.'
Charge a levy -the government is more likely to be subsidising storage (the governments refusal to do so sunk the original proposal) or raising prices to fund it - there won't be any money coming back to taxpayers.
Ho you’ve turned up here now.
BV,
What Govts should be doing is charging a defined levy on the Offshore Wind Farm Operators to ensure that the decommissioning costs are fully covered, so the taxpayer doesn't get the bill.
This is similar to the mechanism in place for the UKCS, where since the start of production, an additional tax is paid from production to ensure that the taxpayer pays nothing (despite the claims of some) for the decommissioning program at the end of the field life.
In effect, it's a multi-billion, decades long loan to HM Govt.
The money left in the fund at the end of the Decom program isn't returned to the Operator, it's kept by the Govt..
The wind farm Operators are supposed to be putting funds aside from their operating profits to ensure that they have the funds available, but many of them aren't.
Many are complaining that the gas price has come down to pre-war levels, so why haven't their bills come down too what they were before?
It's due to two factors.
Firstly, the oil industry had a big inflation spike, just the same as everyone else.
Secondly, the mantra "cheap renewable energy" is wrong. The FSLCoE of offshore static wind is around £200 MWhr.
An eyewatering figure which is why it's a fantasy to claim our energy bills will come down.
More than a little ironic that Kier Starmer was complaining about our reliance on imported energy on TV this morning - but his policies will make us even more reliant on imported energy.
And still, Norway continues to explore for the gas that they know that we - the UK - will need.
