Andy Burnham Set For Clash With MPs Over North Sea Oil And Gas

The title of this post, is the same as that of this article in The Times.

This is the sub-heading.

The prime minister must decide whether to approve the Rosebank oilfield and Jackdaw gasfield but will face opposition from backbenchers if he goes ahead

These are the first three paragraphs.

Andy Burnham faces a potential showdown with Labour MPs after suggesting faster extraction of North Sea oil and gas could help pay for the transition to clean energy.

The prime minister is preparing to decide whether to approve the Rosebank oilfield and Jackdaw gasfield after consultations on both projects closed.

Industry sources have told The Times they believe Burnham will approve Jackdaw but may resist calls to go ahead with Rosebank because of opposition from MPs.

These are my thoughts.

My Boiler, Gas And Jackdaw

Consider.

  • This year my boiler died. So I spent several thousand pounds, but I did get a new gas boiler with a 12-year guarantee.
  • I am now 79, so can this government, or any for that matter, give me a guarantee, that I will live to 91 to get value from my boiler?
  • I know enough about heating, as I have installed a couple of systems for myself, to know that my current house is not suitable for a heat pump.
  • But it may be suitable for some type of electric data centre boiler like heata, which was invented by British Gas Research. But, I’m not hopeful yet!
  • Meanwhile, Centrica have done a large hand-full of deals to keep the country in enough gas to power us through the winter.
  • Some of these are MiQ-certified, which is a bit like Organic for methane, except that emissions are kept to a minimum.
  • I covered MiQ-certification in What Is MiQ-Certification?.

So provided we don’t get an extreme-left scientifically-incorrect government, led by someone like the lady with pink hair in Hackney, I should be able to keep myself warm in winter.

But would I vote for any party, that was going to cut off my gas supply?

But Centrica have been clever.

  • They have plenty of gas storage at Rough.
  • Their press releases show they are buying gas according to MiQ.
  • Grain LNG Terminal, which they bought last year has an export facility, so any spare gas they have can be exported to a country to replace coal or Russian gas.
  • MiQ-certified gas probably fetches a higher price.
  • Centrica would be an obvious purchaser for any North Sea gas.

This gives some dates of the players and Jackdaw

  • BG Group and Centrica were demerged from British Gas plc in 1997.
  • BG Group discovered Jackdaw in 2005.
  • BG Group were taken over by Shell in 2015.

If I was the owner of Jackdaw, I would make sure that my gas had the highest MiQ possible.

If I was energy minister, I’d enforce it.

Will Jackdaw Be A Tie-Back To Shearwater?

I’ve read that it might be, so I asked Google AI and received this answer.

Yes, Jackdaw is designed and developed as a 30-kilometer (approx. 18.5 miles) subsea tie-back to the existing Shearwater platform in the central North Sea.

Project Connection Details

Infrastructure: A multi-phase subsea pipeline links the unstaffed Jackdaw wellhead platform directly to the Shearwater hub.

Processing: Hydrocarbons extracted from Jackdaw will be processed and routed through Shearwater before final export onshore to the St Fergus terminal.

Distance: The subsea pipeline spans roughly 30 kilometers (18.5 miles) northwest from the Jackdaw field to the Shearwater installation.

I also found this detailed article on the Chemical Engineer which is entitled Shell To Invest In Shearwater Gas Infrastructure Hub.

Shell certainly seem to be doing comprehensive planning to bring the gas from Jackdaw to the mainland.

  • Currently, gas from the Shearwater hub is sent to Bacton in Norfolk.
  • After, Jackdaw is connected to Shearwater, the gas will be sent to St. Fergus, which is North of Aberdeen.
  • Google AI says that The Shearwater hub is located approximately 140 miles (225 kilometers) east of Aberdeen in the Central North Sea.

It’s probably all in a day’s work for engineers in the North Sea, but it doesn’t sound to be the easiest project to me.

Will The Jackdaw Gas Field Be Used For CO2 Storage?

I felt this could be a possibility, so I asked Google AI, the question and received this answer.

No, the Jackdaw gas field will not be used for CO2 storage.It is an active natural gas extraction project in the North Sea, though CO2 separated from its extracted gas may eventually be routed to external storage.

Field Status and CO2 Handling

Extraction only: The underground reservoirs at Jackdaw contain natural gas and high-pressure/high-temperature hydrocarbons rather than being purposed for carbon storage.

Onshore processing: Gas from the field comes ashore at St Fergus, where carbon dioxide mixed into the raw gas stream is removed during processing.

Broader CCS links: While Jackdaw itself is a producing asset, its operations tie into Shell’s broader involvement with the regional Acorn Carbon Capture and Storage project, which aims to pipe and sequester CO2 elsewhere.

That was a definite no, that Jackdaw will not be used for Carbon Capture and Storage, but the carbon dioxide in the gas may be stored in the Acorn Carbon Capture and Storage project.

Will Centrica Be Applying Just-in-Time-Delivery To Gas Cargoes?

One of the jobs, I was involved in was scheduling container ships for OCL, in the 1970s.

  • I’m fairly certain, that ships were speeded up and slowed down, so that ports weren’t overloaded.
  • It was all done with my PERT7 project management software, which ran on Time Sharing at Great Portland Street.

I can envisage a clever programmer at Centrica writing a large simulation of all their natural gas deals and calling off gas cargoes, when required.

  • Gas tankers would be constantly sailing between the gas fields in the Americas and LNG Terminals like Grain, where the cargo was needed.
  • It would be nice to have a local supply of natural gas to fill in the gaps between cargoes, but delaying and speeding up of deliveries would have the same effect.
  • I also suspect cargoes could be diverted to Germany, Poland or the highest bidder, when there is a glut of gas.

It could be a classic example of advanced control engineering, but very similar to what OCL were doing fifty years ago.

By applying just-in-time-delivery to gas cargoes, Centrica would reduce the need for storage in the UK.

At least gas doesn’t have a sell-by date!

How Much Liquid Natural Gas Storage Is There At The Grain LNG Terminal?

Google AI gave me this answer to the question in the title of this section.

The Grain LNG terminal on the Isle of Grain in Kent has a total liquid natural gas (LNG) storage capacity of 1.2 million cubic metres (1,200,000 m³) following recent site expansions.

Terminal Storage Overview

Total Capacity: 1.2 million m³ of cryogenic tank space (increased from the original 1.0 million m³ capacity).

Tank Configuration: Consists of massive full-containment cryogenic storage tanks (such as the 190,000 m³ tanks added in phases).

System Throughput: The facility can process up to 15 million tonnes per annum (mtpa), meeting a significant share of the UK’s total gas demand.

It should be remembered that storing gas as liquid reduces the space needed.

What Is The Capacity Of A Typical LNG Carrier?

Google AI gave me this answer to the question in the title of this section.

A typical modern liquefied natural gas (LNG) carrier has a cargo capacity of approximately 174,000 cubic meters (m³).

This size has become the conventional standard for new builds, balancing port compatibility with transport scale, though global fleet capacities range widely from small-scale vessels to massive ultra-large ships.

Vessel Size Categories

Small-scale carriers: Hold roughly 1,000 m³ to 40,000 m³, used for regional distribution and bunkering.

Medium-scale carriers: Range from 40,000 m³ to 80,000 m³.

Conventional large carriers: Standard modern designs cluster around 140,000 m³ to 180,000 m³, with 174,000 m³ dominating recent ship orders.

Maxi-size carriers (Q-Flex and Q-Max): Specialized ultra-large vessels reach capacities between 210,000 m³ and 266,000 m³, primarily built to service long-distance routes out of Qatar.

Grain LNG Terminal can hold about four cargoes from the largest LNG Carriers.

My extensive experience of writing scheduling algorithms, which go back to one I wrote at ICI Mond in 1968, feels that by scheduling the arrival of the ships, there may well be enough storage at Grain LNG Terminal to keep the UK in gas.

I wonder, if for some time, Centrica have known, that they don’t need Rough for natural gas storage, which is why they have ambitions to turn it into hydrogen storage.

Biggest Untapped UK Oil Field, Rosebank, Approved By Regulators

The title of this post, is the same as that of this article on the BBC.

This is the BBC’s summary so far.

  • The UK’s largest untapped oil field has been approved by regulators
  • Rosebank, 80 miles west of Shetland, is estimated to contain 500 million barrels of oil
  • The UK government welcomes the decision, saying it will raise billions of pounds and “make us more secure against tyrants like Putin”
  • But Scotland’s First Minister Humza Yousaf says he’s “disappointed”, while the Green Party calls the decision “morally obscene”
  • Regulators said net zero considerations had been taken into account

This is my summary.

I have been reading Equinor’s web site on Rosebank.

Production will use what is known as a Floating Production Storage and Offloading Vessel or FPSO, which means, when they’ve finished, it can just sail away.

The FPSO will also be electrification-ready, so that all operations on the vessel will probably be powered by green electricity from a nearby wind farm, instead of by a gas turbine engine on the vessel, which burns gas.

This means that the offshore operations will be as carbon-free as is reasonably possible. But importantly, we will pipe the maximum amount of gas from the field for either our own use or selling to the gas-thirsty Germans.

We will need the gas for some time to back up wind and solar with gas-fired power stations.

But what about the emissions from the power stations?

Capturing carbon dioxide from a power station is getting easier, but more importantly, researchers are finding more and more innovative ways of using the carbon dioxide.

H & M and Zara are even selling clothes made from captured carbon dioxide.

Ways are also being developed using plasma electrolysis to strip the carbon out of natural gas to leave useful hydrogen.

Natural gas will be our friend for many decades yet, if we can turn it into a zero-carbon fuel, which I believe we can!

Equinor Is Counting On Tax Breaks With Plans For North Sea Oilfield

The title of this post, is the same as that, of this article in The Times.

These paragraphs outline the project.

Norway’s state-owned oil company is pushing ahead with plans to develop Britain’s biggest untapped oilfield after confirming that it stands to benefit from “helpful” tax breaks introduced alongside the windfall levy.

Equinor could lower its windfall tax bill by as much as £800 million in the years to come thanks to investment relief if it develops the Rosebank field, according to Uplift, a campaign group.

Rosebank, to the west of Shetland, could cost £4.1 billion to develop and may account for about 8 per cent of British oil output in the second half of this decade, producing 300 million barrels of oil by 2050.

Equinor said yesterday that it hoped to take a final investment decision on the field by next year and to start production by 2026. It has applied for environmental approval from the government.

Needless to say Greenpeace are not amused.

We Have Both Long Term And Short Term Energy Problems

In the UK, energy is generally used as electricity or gas and to power industry and transport.

Electricity

In the long term, we need to decarbonise our electricity production, so that all our electricity is produced from zero-carbon sources like nuclear, solar, tidal, wave and wind.

  • As I write this, our electricity production is around 26.8 GW of which 62 % is coming from renewable sources.
  • Surprisingly around 45 % of the renewables is coming from solar. Who’d have ever thought that in an predominantly-grey UK?
  • As we have committed to around 50 GW of wind power by 2030 and the 3.26 GW Hinckley Point C will be on stream by the end of the decade, the long term future of electricity production looks to be fairly secure.
  • It would be even more secure, if we added around 600 GWh of storage, as proposed in Highview Power’s Plan To Add Energy Storage To The UK Power Network, which would be used as backup when the sun doesn’t shine and the wind doesn’t blow.

It looks to me, that our long term electricity problem is capable of being solved.

For the next few years, we will need to rely on our existing gas-fired power stations until the renewables come on stream.

Gas

Gas could be more of a problem.

  • I wouldn’t be surprised to see a lot of resistance to the replacement of natural gas for heating, cooking and industrial processes.
  • Natural gas is becoming increasingly difficult to source.
  • As I said in the previous section, we will still need some gas for electricity generation, until the massive wind farms are completed.

On the other hand, there is HyDeploy.

I like the HyDeploy concept, where up to 20 % of hydrogen is blended with natural gas.

  • Using a blend of hydrogen and natural gas doesn’t require any changes to boilers, appliances or industrial processes.
  • The hydrogen blend would make the most of our existing world class gas network.
  • Customers do not require disruptive and expensive changes in their homes.
  • Enormous environmental benefits can be realised through blending low carbon hydrogen with fossil gas.
  • The hydrogen blending could happen, where the natural gas enters the network at terminals which receive gas from the UK continental shelf or where liquified natural gas is imported.
  • Alternatively, it may be possible to surround a gas production platform with an offshore wind farm. This could enable hydrogen production and blending to be performed offshore.

The amount of gas we need would drop by twenty percent.

In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I calculated that 148.2 tonnes per hour of hydrogen would be needed, to blend twenty per cent of hydrogen into UK natural gas supplies.

I also said this about the electricity needed.

To create 148.2 tonnes per hour of hydrogen would need 8,180.64 MW of electricity or just under 8.2 GW.

I also calculated the effect of the hydrogen on carbon dioxide emissions.

As twenty percent will be replaced by hydrogen, carbon dioxide emission savings will be 24,120,569.99 tonnes.

I believe that generating the 8.2 GW of electricity and delivering the 148.2 tonnes per hour of hydrogen is feasible.

I also believe that HyDeploy could be a valuable way to reduce our demand for natural gas by twenty per cent.

Transport

Not every vehicle, ship, aircraft and train can be powered by electricity, although batteries will help.

Hydrogen will help, but we must also develop our capability for sustainable fuels made from rubbish diverted from landfill and biologically-derived ingredients like used cooking oil.

Summing Up Our Long Term And Short Term Energy Problems

We obviously have got the problem of creating enough renewable energy for the future, but there is also the problem of how we keep everything going in the interim.

We will need gas, diesel, petrol and other fossil fuel derived products for the next few years.

Is Rosebank Our Short Term Solution?

This page on the Equinor web site is entitled Rosebank Oil And Gas Field.

This introductory paragraph described the field.

Rosebank is an oil and gas field 130 kilometres off the coast of the Shetland Islands. Equinor acquired the operatorship in 2019 and has since then been working to optimise and mature a development solution for the field together with our partners.

Could the field with its resources of oil and gas, be just the sort of field to tide us over in the next few difficult years.

But given the position, it will surely not be an easy field to develop.

These two paragraphs set out Equinor’s strategy in developing the field.

Equinor believes the field can be developed as part of the UK Government North Sea Transition deal, bringing much needed energy security and investment in the UK while supporting the UKs net zero target. According to a socioeconomic study (see link below) based on data and analysis by Wood Mackenzie and Voar Energy, if sanctioned Rosebank is estimated to create GBP 8.1 billion of direct investment, of which GBP 6.3 billion is likely to be invested in UK-based businesses. Over the lifetime of the project, Rosebank will generate a total of GBP 24.1 billion of gross value add (GVA), comprised of direct, indirect and induced economic impacts.
Equinor together with our partners are working with the supply chain to ensure that a substantial part of investment comes to Scotland and the UK. A supplier day was held in Aberdeen in partnership with EIC in order to increase the number of local suppliers to tender.

Note.

  1. The sums that could accrue to the UK economy are worthwhile.
  2. The Government North Sea Transition Deal is worth a read.
  3. A lot of the deal is about converting oil and gas skills to those of a renewable energy economy.

Planned properly, we should get all the oil and gas we need to get through difficult years.

I particularly like these two paragraphs, which are towards the end of the Government North Sea Transition Deal.

Through the Deal, the UK’s oil and gas sector and the government will work together to deliver
the skills, innovation and new infrastructure required to decarbonise North Sea oil and gas
production as well as other carbon intensive industries. Not only will it transform the sector in
preparation for a net zero future, but it will also catalyse growth throughout the UK economy.
Delivering large-scale decarbonisation solutions will strengthen the position of the existing UK
energy sector supply chain in a net zero world, securing new high-value jobs in the UK,
supporting the development of regional economies and competing in clean energy export
markets.
By creating the North Sea Transition Deal, the government and the UK’s oil and gas sector are
ambitiously seeking to tackle the challenges of reaching net zero, while repositioning the UK’s
capabilities to serve the global energy industry. The Deal will take the UKCS through to
maturity and help the sector pivot towards new opportunities to keep the UK at the forefront of
the changing 21st century energy landscape.

I believe that developing Rosebank could enable the following.

  • The oil and gas we need in the next few years would be obtained.
  • The economic situation of the UK would be improved.
  • The skills and techniques we need to decarbonise the UK would be delivered.
  • Net-zero would be reached in the required time.
  • Jobs will be created.
  • The export of surplus oil and gas.

I strongly believe that developing the Rosebank field would be worthwhile to the UK.

I have some other thoughts.

Electrification Of Platforms

This page on the Equinor web site is entitled Electrification Of Platforms.

This paragraph explains what that means.

Electrification means replacing a fossil-based power supply with renewable energy, enabling a reduction in greenhouse gas emissions. Equinor is fully committed to reducing emissions from our offshore oil & gas production.

Note.

  1. Typically, platforms use gas turbine engines running on natural gas to provide the electricity needed on the platform.
  2. Platforms in the future will get their electricity from renewable sources like wind and will have an electricity cable to the shore.
  3. Rosebank will be powered in this way.

This document on the Equinor web site is entitled Rosebank: Investing In Energy Security And Powering A Just Transition, which has a section called How Is Rosebank Different?, where this is said.

The key difference of Rosebank compared to other oil fields is that it
aims to draw on new technology applications to help reduce carbon
emissions from its production, through FPSO electrification.

Building offshore installations that can be powered by electricity reduces
reliance on gas powered generators which are the biggest source
of production emissions. The electrification of UKCS assets is vital to
meeting the North Sea Transition Deal’s target of reducing production
emissions by 50% by 2030, with a view to being net zero by 2050.

Electrification of Rosebank is a long-term investment that will drastically
cut the carbon emissions caused by using the FPSO’s gas turbines for
power. Using electricity as a power source on Rosebank results in a
reduction in emissions equivalent to taking over 650,000 cars off the
road for a year compared with importing 300 million barrels of oil from
international sources.

Note.

  1. An FPSO is a Floating Production Storage And Offloading Unit, which is the method of production, that  Equinor have chosen for the Rosebank field.
  2. If we are going to extract fossil fuels then we must extract them in a manner, that doesn’t add to the problem by emitting extra carbon dioxide.
  3. We will probably extract fossil fuels for some years yet, as they are the easiest route to some important chemicals.
  4. I also believe that we will increasingly find uses for any carbon dioxide captured in combustion and chemical processes.

I already know of a farmer, who heats greenhouses using a gas-powered combined heat and power unit, who pipes the carbon dioxide to the tomatoes in the greenhouses.

Despite what Greenpeace and others say, carbon dioxide is not all bad.

Energy Security

The last page of this document on the Equinor web site is entitled Rosebank: Investing In Energy Security And Powering A Just Transition, is entitled Energy Security.

Look at the numbers.

  • £8.1 billion – Total field investment with 78% of this being spent in the UK
  • 1600 – Estimated peak number of direct FTE jobs
  • £24.1 billion – Estimated gross value add
  • 8 % – Of UK oil production from Rosebank to 2030
  • 39 million cubic feet per day – Average daily gas production over the first 10 years of field life, equivalent to almost twice Aberdeen’s daily gas consumption
  • 250kt CO2 – Carbon avoided by reusing existing FPSO

And if you have time read it fully.

Could The Rosebank FPSO Be Powered By Floating Offshore Wind?

Floating wind turbines are now being installed around the world.

  • They can use the largest turbines.
  • Some designs perform in the roughest of seas.
  • They have a high capacity factor.
  • They are generally brought into a suitable port for servicing and updating.
  • Floating wind farms can be connected to floating substations

There is at least 20 GW of floating wind turbines planned for UK waters.

So could an appropriately-sized floating wind farm be placed near the Rosebank FPSO to provide it with electricity?

I don’t see why not, if there were some energy storage in the system, for when the wind wasn’t blowing.

Floating Offshore Wind Close To The Rosebank FPSO Would Be Challenging

Rosebank is an oil and gas field 130 kilometres off the West coast of the Shetland Islands.

That would be a challenging location for floating wind turbines.

But solving the installation problems would set precedents for floating wind farms all over the world.

Could The Rosebank FPSO Handle Hydrogen From Floating Offshore Wind?

It would surely be possible to put an electrolyser in the system somewhere, so that hydrogen was also stored in the tanks of the FPSO.

I also don’t think it unfeasible, that twenty percent of hydrogen could be blended into the natural gas to create the low-carbon natural gas, that has been proposed by the HyDeploy project.
