The Other Upside To Fracking
If you believe that we can successfully solve the problems of extracting gas from the ground using fracking, it should give us enough gas for our needs for many years to come according to reports like this one.
In all of the discussions about fracking, no-one seems to mention how you transform this gas into useful electricity. You put it through an enormous gas turbine engine and this powers some form of electricity generator. Normally these days they work on a principle called combined cycle and you see the term CCGT (combined cycle gas turbine) used. But which British company is involved in this technology? Rolls-Royce is the answer. Unfortunately, their turbines don’t seem to be used in our numerous gas-fired power stations. But I know they could be.
I’ve found this link to a company, I’d never heard of before called Centrax, who integrate Rolls Royce Trent 60 WLE engines into power generation sets. Their web page is here. And this is their page on using the Trent 60 WLE .
So if we have all this gas, will it lead to extra jobs in the manufacturing sector?
It could do if we get it right!
Should We Have Unit Pricing For Energy?
Go back thirty years or more and you paid for what you used with energy. I’m not sure if you paid a standing charge, akin to a telephone line rental, but you knew exactly where you stood. If you used more electricity you paid more money.
Now it is not as simple and to be cynical, I think the energy companies like it that way, as customers find it hard to compare prices.
So when EDF suggests going back to simple pricing, as is stated in this report, do I think it is a good thing?
Of course I do!
But there is something we need even more urgently and that is a smart meter, so we can see how much electricity and gas we are using.
I haven’t seen any reports yet, but a smart meter connected to a smart phone and then linked back to smart heating controls, must save a lot of money. Just think of this simple case. Do you switch your central heating on and off, at the most optimum times. Without information you’re just fishing in the dark.
But I doubt I’ll ever see unit pricing and smart metering, as the energy companies will do all they can to delay its implementation.
A Message For nPower Customers
After my article on nPower’s cheaper tariff, that they hadn’t told me about, I’ve just had a phone call from a friend, who saw it and like me he saved a few hundred pounds by not switching suppliers, but by switching tariffs.
So if like my friend and myself, you get your energy from nPower, it might be worth checking with one of the comparison sites to see if you are getting the best deal. You may find a painless call to the company, will save you money, without changing energy suppliers and hopefully little hassle.
Sorting Out My Energy
Every so often, I check up to see if I’ve got the best energy deal. As some companies are now offering smart meters, I wondered if I could get one of these thrown in.
So I checked one of the comparison sites and found, that I could save four hundred or so a year, by swapping to nPower.
As my current supplier is nPower, I found that strange, as I thought, I was supposed to be on the lowest tariff, according to new government legislation.
So I phoned them up and got changed onto the new tariff. The only downside is that there is now a £60 cancellation fee!
I can’t help thinking, that all of this has a touch of professional theft about it.
I think the moral of this story, is that you should check your energy bills against the rest of the industry probably twice a year.
You might be surprised, as I was, that one short phone call, saves you a few hundred pounds.
I still haven’t got my smart meter though! But then the big companies are reluctant to bring those in, as it will both cost them money for the meter and because savvy customers will cut their energy use.
My Dual Fuel Bill
I seem to pay £154 a month for this.
I wouldn’t know if that is high or low, except that it’s certainly a lot less than I used to pay in the two previous houses.
Smoking Bans Lead To Fall In Asthma
This report on the BBC, says there is a link between the smoking ban and a drop in the number of children admitted to hospital with asthma. Here’s a relevant paragraph.
We increasingly think it’s because people are adopting smoke-free homes when these smoke-free laws are introduced and this is because they see the benefits of smoke-free laws in public places such as restaurants and they increasingly want to adopt them in their home.
I also think, that children are also badgering their parents not to smoke.
When we were developing the metered dose inhaler for drugs, like those for asthma, I came across some research that showed any naked flame in the house increased the oxides of nitrogen in the air, that might be causing asthma. This page from the US EPA outlines the problem and gives advice.
So I would never have a gas cooker or fire in my house. There was one when I bought this house, but I sold it.
Fracking In The Times
The Times yesterday also had an article in favour of fracking from Alice Thomson.
As an engineer and a scientist, I tend to dismiss emotional arguments about anything, when the science and technology says otherwise. In this article, I outlined a few thoughts on the subject. I stated this in the article.
The technologies employed are still very much under development and have been used mainly in the very underpopulated parts of the United States and Canada. The extraction is now moving towards more populous states, like Pennsylvania, and only when it is totally accepted by the inhabitants there, will it be time to use it in Europe.
My views haven’t changed and as I said we should keep a watching brief.
We should also do more research, as I said here.
One point that we forget about onshore energy extraction, is that in Wytch Farm, we have one of the largest onshore oil fields in Europe. It’s also slap bang in beautiful countryside. Do we here a massive movement to close it? To me, it proves that in the UK, the oil and gas industry can be good neighbours.
If we can use fracking safely, I believe that the economics say that our energy bills will drop.
Another Clue In The Mystery Of The Rogue Central Heating
Yesterday, I had a guy from G4S call looking for a Mr. Smith, who supposedly lived in the flat above my house. It was about non-payment of an energy bill to British Gas.
Now, there is no flat above my house, I’ve never dealt with British Gas and the guy said he was looking for a prepayment meter, which doesn’t exist.
So after an amicable discussion, he made a few notes and left.
The whole episode got me thinking. When I moved into this house, some of the wiring was unusual to say the least. So did someone crudely split the house into two separate flats to maximise his income.
This would certainly explain the very dodgy and crude wiring in the heating manifold.
So perhaps, I’m wrong to blame Jerry in this instance, when it appears it was some amateur, who had a possible grudge against me.
Fracking May be Good for You
There is a great deal of opposition to the use of fracking to extract gas from shale in this country.
I went to a lecture at the Royal Geograhical Society yesterday called Unconventional Gas. It was very enlightening and I can draw various conclusions from the lecture. You can find out more about the lecture here.
The first is that there is a very large amount of gas available to be extracted using fracking and a lot of it is in countries, with pretty stable regimes, like Australia, Canada and the United States.
The second is that gas prices in North America are falling fast, because of the large amounts of gas now available. I believe, that Canada has far too much gas for its own use and will soon start to export.
So it is not inconceivable, that Europe will start to import gas from North America rather than from regimes like Russia and Qatar.
Am I wrong to therefore suggest that because of fracking, we may well find that our gas prices start to drop?
I have deliberately not discussed the use of fracking in the UK and Europe.
The technologies employed are still very much under development and have been used mainly in the very underpopulated parts of the United States and Canada. The extraction is now moving towards more populous states, like Pennsylvania, and only when it is totally accepted by the inhabitants there, will it be time to use it in Europe.
In the meantime we should keep a strong watching brief, investing in resarch in the best universities, as I outlined here.
But as with many things, there are many against the technology, when it starts to be used, but now it is totally accepted. Just look at the opposition Brunel, Stephenson and others had when they started building railways!
Could Fracking Be The Saviour of the North?
I can remember a documentary on the BBC in probably the 1960s about how a Scottish company extracted oil from shale rock. I don’t know whether they still do. I have just found this museum to the industry and it says it closed in 1962.
According to today’s Sunday Times, there is enough shale gas in the shale deposits mostly in the north of England to last 70 years.
Now I know extracting shale gas is controversial, especially, where the process of fracking is used. There was controversy in the Blackpool are, as fracking was blamed for a couple of small earthquakes. Read about it here.
But then there was controversy, when horseless carriages first arrived on British roads and they had to be preceded by a man with a red flag.
I’m not saying there is no risk from fracking, but I do think, that with proper research fracking will be safe to use in many places in the world.
And eventually, it will be used in many places in the UK, when the problems are sorted out. After all, we mined coal for years, despite the subsidence risk nearby.
And remember that for the same amount of energy coal produces forty-percent more CO2! This is because coal is pure carbon, whereas natural gas is a mixture of Hydrogen H2 and Methane, CH4, so it produces a large proportion of water when it burns.
Hopefully, I’ll know more later in the week, when I have gone to the Geological Society of London to hear a lecture.
The other thing about shale gas in the UK, is that it is located where we need jobs; in the north of England. So it becomes a vote winner for whoever wants to play the shale gas card.
Any extraction of shale gas, should be linked to two measures.
1. A local extraction tax, that goes directly to the local authorities over the extraction. This was proposed in the seventies, by someone I knew, as a means of pursuing oil extraction in places like Surrey, which in his knowledgeable view was one of the most likely places to find oil in the UK. Imagine the fuss it would create if large quantities of oil were found under say Epsom. But if Surrey got enough money to build everything they needed, the reaction of some might be different.
2. Full insurance for any buildings damaged by extraction process.
Politicians and the press will see it as a simple black and white issue. Most will be against! I see it as a multi-coloured jigsaw, that must be based on sound technology.
I would start by setting up an well–funded Institute of Fracking, at a university that has the reputation to recruit some of the best researchers in the world. It may prove that fracking is a dead end but if it showed that it was economically viable in the UK, we would reap the benefit in spades.
I have just found this article from the American Consumer Institute. It makes a lot of interesting points. Note that the United States has a local extraction tax in some or all states and this seems to push opinion in various directions.
I think the worst thing we could do is ban fracking, with the second worst being to ignore it.
Whatever we do, because we have so much of this gas, we should set up some form of research institute.
There is also a page of expert opinion to the Qradilla report on the links between fracking and earthquakes at Blackpool.
