Coal Sales Could Lose Tens Of Millions For Consumers

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

These two paragraphs outline the story.

A huge stockpile of coal bought for emergency use in power stations this winter is due to be resold at a loss of tens of millions of pounds to consumers.

National Grid funded the procurement of hundreds of thousands of tonnes of coal as part of a deal to keep open five coal-fired units this winter. The estimated £368 million cost of the “winter contingency contracts”, which includes an undisclosed sum for the coal purchases, is being recouped via energy bills.

Note.

  1. None of the coal has been burned, as the weather was warmer than expected,
  2. It is now sitting in various places around the country.
  3. It will probably sell at a loss and there will be transport costs.

I will look at the mathematics of disposal.

Burning Fossil Fuels

On the Internet, I have found these figures.

  • If you burn a kilogram of natural gas you create 15.5 KWh of electricity and 2.75 kilograms of carbon dioxide.
  • If you burn a kilogram of coal you create 2.46 KWh of electricity and 2.38 kilograms of carbon dioxide.

This means that natural gas and coal create 0.18 and 0.97 kilograms of carbon dioxide respectively for every KWh generated.

I believe these figures say, that if we have to use a fossil fuel, gas will be much better than coal for climate change reasons.

The Size Of The Problem

We are talking about 130,000 tonnes of coal for EDF and 400,000 for Drax. Uniper’s figure is not stated. Let’s say they make the coal pile up to 600,000 tonnes.

Burning this pile will generate 1,476,000 KWh or 1.476 GWh of electricity and create 1428,000 tonnes of carbon dioxide.

Effect On Total UK Carbon Dioxide Emissions

According to government figures on the Internet in 2021 we emitted 107.5 million tonnes of carbon dioxide.

Burning all that coal in a year, would add less than 1.5 % to our carbon dioxide emissions. Perhaps we should burn it strategically over a number of years, when there are energy supply problems, as it is after all a crude form of energy storage.

What Would I Do With The Savings?

The money saved on the transport and making loss-making sales could be spent on other ways to save carbon emissions, like converting surplus wind energy into hydrogen and blending it with the gas.

I discussed the mathematics of hydrogen blending in UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025.

If we put 2 % hydrogen in our natural gas, this would save nearly 2.5 million tonnes of carbon dioxide emissions in a year. This figure is much bigger than the 1428,000 tonnes of carbon dioxide, that would be created by burning all the coal.

At a level of 2 %, most appliances, boilers and industrial processes would work without change. But a good service would help.

UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025

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

These are the first three paragraphs.

Hydrogen to be added to Britain’s gas supply by 2025.

Hydrogen is to be pumped into Britain’s main gas pipeline by 2025 as part of a scramble to ditch fossil fuels and move to net zero.

Between 2% and 5% of the fuel flowing through the country’s transmission network will be hydrogen in two years under plans drawn up by National Gas, which owns the pipelines.

Note.

  1. The article says that.on a winter’s day, you’ve got seven times more energy going through the gas network than the electricity network.
  2. Between 2% and 5% of hydrogen, would be unlikely to mean that appliances, boilers and industrial processes would need to be changed.
  3. I suspect that domestic appliances and boilers would just need a good service.
  4. HyDeploy has shown that 20 % of hydrogen could be possible.
  5. The hydrogen could be added, where the natural gas enters the UK gas network.

The exercise would save a lot of carbon emissions.

How Much Electricity Would Be Needed To Create The Hydrogen?

In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I calculated the amount of hydrogen that would be needed for 20 %, how much electricity it would need and how much carbon dioxide would not be emitted.

How Much Hydrogen Needs To Be Added?

This page on worldodometer says this about UK gas consumption.

The United Kingdom consumes 2,795,569 million cubic feet (MMcf) of natural gas per year as of the year 2017.

I will now calculate the weight of hydrogen needed to be added.

  • 2,795,569 million cubic feet converts to 79161.69851 million cubic metres.
  • I will round that to 79161.7 million cubic metres.
  • Twenty percent is 15832.34 million cubic metres.
  • A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 1,298.25188 million kilograms will need to be added to the UK gas supply.

This is 1,298,251.88 tonnes per year, 3,556.85 tonnes per day or 148.2 tonnes per hour.

How Much Electricity Is Needed To Create This Amount Of Hydrogen?

In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.

Ryze Hydrogen are building the Herne Bay electrolyser.

  • It will consume 23 MW of solar and wind power.
  • It will produce ten tonnes of hydrogen per day.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

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

How Much Carbon Dioxide Would Be Saved?

This page on the Engineering Toolbox is entitled Combustion Of Fuels – Carbon Dioxide Emission and it gives a list of how much carbon dioxide is emitted, when a fuel is burned.

For each Kg of these fuels, the following Kg of carbon dioxide will be released on combustion.

  • Methane – 2.75
  • Gasoline – 3.30
  • Kerosene – 3.00
  • Diesel – 3.15
  • Bituminous coal – 2.38
  • Lignite 1.10
  • Wood – 1.83

Engineering Toolbox seems a very useful web site.

I will now calculate how much carbon dioxide would be saved.

  • In 2017, UK methane consumption was 79161.7 million cubic metres.
  • One cubic metre of methane weighs 0.554 Kg.
  • The total weight of methane used is 43,855,581.8 tonnes.
  • Multiplying by 2.75 shows that 120,602,849.95 tonnes of carbon dioxide will be produced.

As twenty percent will be replaced by hydrogen, carbon dioxide emission savings will be 6,030,142.498 tonnes.

That seems a good saving, from a small country like the UK.

The UK would also reduce natural gas consumption by twenty percent or 15832.34 million cubic metres per year.

 

How Much Electricity Would Be Needed To Create The Hydrogen for a 5 % Blend?

I’ll now repeat the calculation for a 5 % blend,

How Much Hydrogen Needs To Be Added?

I will now calculate the weight of hydrogen needed to be added.

  • UK gas consumption rounds to 79161.7 million cubic metres.
  • Five percent is 3958.085 million cubic metres.
  • A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 324.56297 million kilograms will need to be added to the UK gas supply.

This is 324,563 tonnes per year, 889.21 tonnes per day or 37 tonnes per hour.

How Much Electricity Is Needed To Create This Amount Of Hydrogen?

Earlier I said this.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

To create 37 tonnes per hour of hydrogen would need 2,045.16 MW of electricity or just over 2 GW.

How Much Carbon Dioxide Would Be Saved?

Earlier, I found that a Kg of methane will produce 2.75 Kg of carbon dioxide on combustion.

I will now calculate how much carbon dioxide would be saved.

  • In 2017, UK methane consumption was 79161.7 million cubic metres.
  • One cubic metre of methane weighs 0.554 Kg.
  • The total weight of methane used is 43,855,581.8 tonnes.
  • Multiplying by 2.75 shows that 120,602,849.95 tonnes of carbon dioxide will be produced.

As five percent will be replaced by hydrogen, carbon dioxide emission savings will be 6030,142.4975 tonnes.

The UK would also reduce natural gas consumption by five percent or 3958.085 million cubic metres per year.

How Much Electricity Would Be Needed To Create The Hydrogen for a 2 % Blend?

I’ll now repeat the calculation for a 2 % blend,

How Much Hydrogen Needs To Be Added?

I will now calculate the weight of hydrogen needed to be added.

  • UK gas consumption rounds to 79161.7 million cubic metres.
  • Two percent is 1,583.234 million cubic metres.
  • A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 129.825 million kilograms will need to be added to the UK gas supply.

This is 129,825 tonnes per year, 355.68 tonnes per day or 14.8 tonnes per hour.

How Much Electricity Is Needed To Create This Amount Of Hydrogen?

Earlier I said this.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

To create 14.8 tonnes per hour of hydrogen would need 817 MW of electricity or not even a GW.

How Much Carbon Dioxide Would Be Saved?

Earlier, I found that a Kg of methane will produce 2.75 Kg of carbon dioxide on combustion.

I will now calculate how much carbon dioxide would be saved.

  • In 2017, UK methane consumption was 79161.7 million cubic metres.
  • One cubic metre of methane weighs 0.554 Kg.
  • The total weight of methane used is 43,855,581.8 tonnes.
  • Multiplying by 2.75 shows that 120,602,849.95 tonnes of carbon dioxide will be produced.

As two percent will be replaced by hydrogen, carbon dioxide emission savings will be 2,412,057 tonnes.

The UK would also reduce natural gas consumption by two percent or 1,583.234 million cubic metres per year.

Centrica Announces Hydrogen Ready Combined Heat And Power Partnership With 2G

The title if this post is the same as that of this press release from centrica.

This is the sub-heading.

Centrica Business Solutions is partnering with 2G Energy AG to provide customers with 100% hydrogen ready Combined and Heat Power (CHP) systems.

This paragraph outlines the project.

The move is in response to the growing need for integrated hydrogen solutions which are a key tool in the decarbonisation of decentralised energy. As the hydrogen network develops, the highly efficient units can continue to run on traditional fuel sources, helping future proof investments by ensuring an extended life for the assets.

It does appear that the 2G units can run on biogas or natural gas and switch to hydrogen, when it is available.

2G Energy have a web site, with lots of case studies.

Lithuanian Gas Pipeline Hit By Large Explosion

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

This is the sub heading.

A large blast has hit a gas pipeline in the Pasvalys region of northern Lithuania, near the Latvian border.

This Google Map shows the location of the explosion.

Note.

  1. Country borders are marked as white lines.
  2. The site of the explosion at Pasvalis Vienkiemii, is marked with a red arrow.
  3. Pasvalis Vienkiemii is about a hundred miles from Vilnius.
  4. About a hundred miles to the East of Pasvalis Vienkiemii, is the point, where Belarus, Latvia and Lithuania meet.
  5. Russian territory is about a hundred miles further to the East.

I have experience of the quality of borders in that area.

South-West of Lithuania and lying between that country and Poland, there is the small Russian enclave of Kaliningrad.

These pictures show the border between Poland and the Kaliningrad enclave of Russia.

If the borders between Belarus, Latvia and Lithuania are as secure as this, they are almost an open invitation to saboteurs to enter and do damage.

Neptune Energy, Ørsted And Goal7 Explore Powering Integrated Energy Hubs With Offshore Wind

The title of this post, is the same as that of this press release from Neptune Energy.

These four paragraphs outline the agreement.

Neptune Energy today announced it has signed a Memorandum of Understanding with Ørsted and Goal7 to explore powering new integrated energy hubs in the UK North Sea with offshore wind-generated electricity.

Integrated energy hubs have the potential to combine multiple energy systems, including existing oil and gas production assets, carbon storage and hydrogen production facilities. They could extend the life of producing fields and support the economic case for electrification with renewable energy, to keep carbon emissions low.

The agreement will see the companies examine the potential to supply renewable electricity from Ørsted’s Hornsea offshore windfarm projects to power future Neptune-operated hubs in the UK North Sea.

Goal7 will provide project management support and technical input.

Note.

  1. Neptune Energy has three oil and gas fields in the UK North Sea; Cygnus (operational), Isabella (exploration) and Seagull (development)
  2. Gas from Cygnus comes ashore at the Bacton Gas Terminal.
  3. Ørsted owns the Hornsea wind farm, which when fully developed will have a capacity of around 6.5 GW.
  4. Cygnus and Hornsea could be not much further than 50 km apart.
  5. Seagull and Isabella are further to the North and East of Aberdeen.
  6. Ørsted has an interest in the Broadshore wind farm, which was numbered 8 in the ScotWind Leasing round.

These are my thoughts.

The Cygnus Gas Field And The Hornsea Wind Farm

This could be like one of those stories where boy meets the girl next door and they hit it off from the first day.

This page on the Neptune web site says this about the Cygnus gas field.

The biggest natural gas discovery in the southern North Sea in over 30 years is now the largest single producing gas field in the UK, typically exporting over 250 million standard cubic feet of gas daily. Cygnus contributes six per cent of UK gas demand, supplying energy to the equivalent of 1.5 million UK homes. It has a field life of over 20 years.

Two drilling centres target ten wells. Cygnus Alpha consists of three bridge-linked platforms: a wellhead drilling centre, a processing/utilities unit and living quarters/central control room. Cygnus Bravo, an unmanned satellite platform, is approximately seven kilometres northwest of Cygnus Alpha.

In 2022, we plan to drill two new production wells at Cygnus, with the first of these expected to come onstream in 4Q. The second well is due to be drilled in the fourth quarter and is expected onstream in the first quarter of 2023, with both wells helping to maintain production from the field and offset natural decline.

Gas is exported via a 55 km pipeline. Cygnus connects via the Esmond Transmission System (ETS) pipeline to the gas-treatment terminal at Bacton, Norfolk. Neptune Energy has a 25% minority interest in ETS.

Note.

  1. Cygnus with a twenty year life could be one of the ways that we bridge the gap until we have the two Cs (Hinckley Point and Sizewell) and a few tens of offshore wind gigawatts online.
  2. The two extra wells at Cygnus will help bridge the gap.
  3. The gas field has a pipeline to Bacton.

So what can the gas field and the wind farm, do for each other?

Hornsea Can Supply The Power Needs Of Cygnus

Typically, ten percent of the gas extracted from the wells connected to a gas platform, will be converted into electricity using one or more gas-turbine engines; which will then be used to power the platform.

So, if electricity from the Hornsea wind farm, is used to power the platform, there are two benefits.

  • More gas will be sent through the pipeline to Bacton.
  • Less carbon dioxide will be emitted in recovering the gas.

Effectively, electricity has been turned into gas.

Electricity Can Be Stored On The Sea-Bed

The Hornsea One wind farm has an area in the order of 150 square miles and it is only one wind farm of four, that make up the Hornsea wind farm.

I would argue that there is plenty of space between the turbines and the wells of the Cygnus gas field to install some form of zero-carbon underwater battery to store electricity.

But does this technology exist?

Not yet! But in UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind, I described a technique called Marine Pumped Hydro, which is being developed by the STORE Consortium.

  • Energy is stored as pressurised water in 3D-printed hollow concrete spheres fitted with a hydraulic turbine and pump.
  • The spheres sit on the sea-bed.
  • This page on the STORE Consortium web site, describes the technology in detail.
  • The technology is has all been used before, but not together.

I think it is excellent technology and the UK government has backed it with £150,000 of taxpayers’ money.

I also believe that Marine Pumped Hydro or something like it, could be the solution to the intermittency of wind farms.

Excess Electricity Can Be Converted Into Hydrogen

Any spare electricity from the wind farm can drive an electrolyser to convert it into hydrogen.

The electrolyser could be mounted on one of the Cygnus platforms, or it could even float.

The hydrogen produced would be blended with the gas and sent to Bacton.

Carbon Dioxide Can Be Stored In The Depleted Cygnus Gas Field

As the gas field empties of natural gas, the gas pipes to the Cygnus gas field can be reversed and used to bring carbon dioxide to the gas field to be stored.

The Cygnus gas field has gone full circle from providing gas to storing the same amount of carbon that the gas has produced in its use.

These are two paragraphs from the press release.

Neptune Energy’s Director of New Energy, Pierre Girard, said: “The development of integrated energy hubs is an important part of Neptune’s strategy to store more carbon than is emitted from our operations and the use of our sold products by 2030.

“Neptune has submitted three applications under the recent Carbon Dioxide Appraisal and Storage Licensing Round, and securing the licences would enable us to develop future proposals for integrated energy hubs in the UK North Sea.

I can envisage a large gas-fired power-station with carbon capture being built in Norfolk, which will do the following.

  • Take a supply of natural gas from the Cygnus gas field via the Bacton gas terminal.
  • Convert the hydrogen in the gas into electricity.
  • Convert the carbon in the gas into carbon dioxide.
  • Store the carbon dioxide in the Cygnus gas field via Bacton.
  • I also suspect, that if a Norfolk farmer, manufacturer or entrepreneur has a use for thousands of tonnes of carbon dioxide, they would be welcomed with open arms.

Would the ultra-greens of this world, accept this power station as zero-carbon?

The Isabella And Seagull Gas Fields And The Broadshore Wind Farm

Could a similar set of projects be applied to the Isabella and Seagull gas fields, using the Broadshore wind farm?

I don’t see why not and they could work with the Peterhead power stations.

Centrica Re-Opens Rough Storage Facility

The title of this post, is the same as that of this press release from Centrica.

It has this sub-heading.

Rough Operational For Winter And Increases UK’s Storage Capacity By 50%.

On the face of it, this sounds like good news and these two paragraphs give more details.

Centrica has announced the reopening of the Rough gas storage facility, having completed significant engineering upgrades over the summer and commissioning over early autumn.

The initial investment programme means the company has made its first injection of gas into the site in over 5 years and is in a position to store up to 30 billion cubic feet (bcf) of gas for UK homes and businesses over winter 2022/23, boosting the UK’s energy resilience.

Note.

  1. The Rough gas storage facility has been able to hold up to 100 billion cubic feet of gas in the past.
  2. Rough is a complex field with two platforms and thirty wells transferring gas to and from the facility.
  3. Additionally, there is an onshore gas-processing terminal at the Easington Gas Terminal, where it connects to the UK gas network.

It appears to be a comprehensive gas storage facility, that should get us through the 2022/3 winter.

These two paragraphs from the press release, which are the thoughts of the Centrica Chief Executive are significant.

Centrica Group Chief Executive, Chris O’Shea, said “I’m delighted that we have managed to return Rough to storage operations for this winter following a substantial investment in engineering modifications. Our long-term aim remains to turn the Rough field into the world’s biggest methane and hydrogen storage facility, bolstering the UK’s energy security, delivering a net zero electricity system by 2035, decarbonising the UK’s industrial clusters, such as the Humber region by 2040, and helping the UK economy by returning to being a net exporter of energy.

“In the short term we think Rough can help our energy system by storing natural gas when there is a surplus and producing this gas when the country needs it during cold snaps and peak demand. Rough is not a silver bullet for energy security, but it is a key part of a range of steps which can be taken to help the UK this winter.”

Note.

  1. Effectively, in the short term, Rough is a store for gas to help us through the winter.
  2. In the long-term, Rough will be turned into the world’s largest gas storage facility.
  3. It will be able to store both methane (natural gas) and hydrogen.

Having worked with project managers on complex oil and gas platforms and chemical plants, I wouldn’t be surprised to find, that when the design of this facility is released, it will be something special.

Centrica certainly seem to have upgraded Rough to be able to play a significant short term role this winter and they also seem to have developed a plan to give it a significant long-term role in the storage of hydrogen.

Aldbrough Gas Storage

A few miles up the coast is SSE’s and Equinor’s Aldbrough Gas Storage, which is being developed in salt caverns to hold natural gas and hydrogen.

Blending Of Hydrogen And Natural Gas

I believe that we’ll see a lot of blending of hydrogen and natural gas.

  • Up to 20 % of hydrogen can be blended, without the need to change appliances, boilers and processes.
  • This cuts carbon dioxide emissions.

I wrote about this in a post called HyDeploy.

It might be convenient to store hydrogen in Aldbrough and natural gas in Rough, so that customers could have the blend of gas they needed.

With two large gas stores for hydrogen under development, the HumberZero cluster is on its way.

Are The Tories Bluffing About Fracking?

I’ve just listened to a Treasury Minister (Chris Philp (?)) on the BBC and he didn’t mention fracking.

But he did mention more oil and gas in the North Sea, where there is a project agreed between the British and Scottish governments called INTOG, which aims to innovatively cut carbon emissions in the North Sea and possibly extract smaller amounts of gas and oil from existing wells.

As you know, I think fracking is irrelevant. It will take a few years to deliver substantial amounts of gas and we can extract more from the North Sea and by repurposing existing wells.

We might even find one or two existing wells, that could be converted to much-needed gas storage.

I also believe that the cash flow in taxes and leases from offshore wind will be astronomic and it can be used to finance borrowing. We did the same with Artemis to finance the company against future sales. But we were only borrowing millions. We used to parcel up all our leases from companies like Shell, NASA and BP and effectively sell them to Lloyds Bank at a discount.

I’m sure that a clever banker could find a mechanism, that converts future income from offshore wind into a magic money tree for today. Is that what Kwasi Kwarteng has done, in order to cut taxes?

The one problem with offshore wind with the public, is that putting in the cables arouses the NIMBYs. It should also be born in mind, that a lot of the grid connections, go through Tory seats, where NIMBYs are very much against more cables.

So I do wonder, if Moggy has announced the start of fracking to give the NIMBYs a target, so they allow the efficiency of offshore oil and gas to be improved and offshore wind farms to be built without hindrance.

Perhaps Moggy should concentrate on the most important thing that our offshore wind industry needs. This is an innovative pricing mechanism for energy storage, that does the following.

  • Allows investors to get a similar return on energy storage to that that they get for offshore wind farms, onshore solar farms and interconnectors.
  • Encourages the building of more energy storage.
  • Assists in the development of novel energy storage ideas.

As one estimate says we need 600 GWh of energy storage in the UK, sorting this pricing mechanism, can’t come soon enough.

The previous government was talking about this, as I wrote in Ministerial Roundtable Seeks To Unlock Investment In UK Energy Storage.

So continue the conversation, Moggy!

Thoughts On The Mini-Budget

This article on the BBC is entitled At A Glance: What’s In The Mini-Budget?.

If nothing else KK has whipped up a storm, with the most tax-cutting budget in decades.

But!

According to my calculations in Will We Run Out Of Power This Winter?, the planned offshore wind that will be installed between 2022 and 2027 will be at least 19 GW. About 3 GW of this offshore wind is already producing electricity.

To this must be added 3.26 GW for Hinckley Point C, 2 GW for solar and 0.9 GW for onshore wind in Scotland, which will be developed by 2027.

So we have 25.2 GW for starters.

Following on from this is the 27.1 GW from ScotWind, about 4 GW from the Celtic Sea, 3 GW from Morecambe Bay and 10 GW from Aker’s Northern Horizons. All of these are firm projects and some are already being planned in detail.

These wind and solar farms are the collateral for KK’s borrowing.

The corporate tax changes will hopefully attract world class energy and manufacturing companies to set up UK-domiciled subsidiaries to develop more offshore wind farms and manufacture the turbines and the electrical gubbins close to where they will be installed.

As more wind farms are built, many GW of electricity and tonnes of hydrogen will be exported to Europe.

Note that 1 GW for a day costs around £ 960,000 and for a year costs £350.4 million.

A big benefit of all this electricity, will be that we won’t need to frack.

Technologies like green hydrogen, that will be created by electrolysis will reduce our need for gas.

We might develop a gas field like Jackdaw, to give us gas for a backup with a few gas-fired power stations, for when the wind doesn’t blow, but gas will only have a minor roll.

The force of the maths is with KK!

Have We Missed The Boat On Fracking?

I have just re-read my post from October 2019, which was entitled Fracking Hell…Is It The End?, where these were my conclusions.

  • Fracking for hydrocarbons is a technique that could be past its sell-by date.
  • The use of natural gas will decline.
  • INEOS could see hydrogen as a way of reducing their carbon footprint.
  • The heating on all new buildings should be zero carbon, which could include using hydrogen from a zero-carbon source.
  • There are reasons to think, that electricity from wind-farms creating hydrogen by electrolysis could replace some of our natural gas usage.

So will the Government’s lifting on the ban on fracking make any difference?

The announcement is detailed in this article on the BBC, which is entitled Fracking Ban Lifted, Government Announces.

These are my thoughts.

Fracking Is Not A Quick Fix

My personal view is that to achieve any significant amounts of gas from fracking will take some years, so it is not something that will be available in the short term.

Opposition To Fracking Won’t Help

There are very few inhabitants of the UK, who are enthusiastic about fracking.

Opposition to fracking will make it less likely to be the feasible short term fix we need in the UK.

Suppose There Was An Earthquake Near To A Fracking Site

Fracking also has the problem, that if there were to be a small earthquake near to a site, even if it was very likely to have not been caused by fracking, it would result in massive public uproar, which would shut down all fracking in the UK.

This to me is a big risk!

Would The Jackdaw Oil And Gas Field Be A Medium Term Solution?

I believe that with other gas field developments and imports, Jackdaw could keep us supplied with enough gas until the end of the decade.

Future Renewable Electricity Production

In Will We Run Out Of Power This Winter?, I summarised the likely yearly additions to our offshore wind power capacity in the next few years.

  • 2022 – 3200 MW
  • 2023 – 1500 MW
  • 3024 – 2400 MW
  • 2025 – 6576 MW
  • 2026 – 1705 MW
  • 2027 – 7061 GW

Note.

  1. Ignoring 2022 as it’s going, this totals to 19.2 GW.
  2. Hopefully, by the end of 2027, Hinckley Point C will add another 3.26 GW
  3. According to Wikipedia, there are currently 32 active gas fired combined cycle power plants operating in the United Kingdom, which have a total generating capacity of 28.0 GW.

I think it is not unreasonable to assume that some of the electricity will enable some of our gas-fired power stations to be stood down and/or mothballed.

Gas consumption would be reduced and some power stations would be held in reserve for when the wind was on strike!

Using Hydrogen To Eke Out Our Gas

Consider.

  • In Lime Kiln Fuelled By Hydrogen Shown To Be Viable, I wrote about how hydrogen can be used instead of or with natural gas to fuel a lime kiln.
  • There are other processes, where hydrogen can be used instead of or with natural gas.
  • Using more hydrogen will reduce the amount of carbon dioxide emitted.

Perhaps we should strategically build a few huge hydrogen electrolysers, so that some large industrial users can cut back on their natural gas.

Will Energy Storage Help?

Energy storage’s main use is to mop up all the surplus electricity when demand is low at a low price and sell it back, when demand is high.

If we waste less energy, we will use less gas.

Will District Heating Schemes Help?

Consider.

More schemes like this should be developed, where there is a readily-available source of heat or electricity

Conclusion

As we add more renewables to our energy generation, it appears to me, that our gas usage will decline.

If we were to go fracking, we should have done it a lot earlier, so we can bridge the short term gap.

It Looks Like The Gas Leak Has Killed The Tree Outside My House

A couple of months ago, I had a gas leak outside my house.

These pictures show the tree outside my house.

It looks like the gas in the soil has given the tree a good kicking.

Incidentally, when I was a child, all the trees in the road outside our house in Cockfosters were killed by gas leaks.
