Sustainable Marine Delivers Floating Tidal Power To Nova Scotia Grid

The title of this post, is the same as that of this article on Renewable Energy Magazine.

This is the first paragraph.

Ocean energy pioneer Sustainable Marine has successfully harnessed the enormous tidal currents in Canada’s Bay of Fundy, delivering the first floating in-stream tidal power to Nova Scotia’s grid.

This Google Map shows the Bay Of Fundy.

Note.

  1. The hydrology of the Bay of Fundy has the highest tidal range in the world of sixteen metres, against a worldwide average of about a metre.
  2. According to the Renewable Energy Magazine article, Nova Scotia has allocated circa 30MW of capacity via demonstration permits.
  3. The article also indicates that up to 2.5 GW of clean and predictable energy for Canada could be generated.
  4. By comparison Hinckley Point C nuclear power station will generate 3.26 GW.

The Bay of Fundy would be the largest tidal power station in the world.

But this list in Wikipedia gives these proposed tidal power stations.

There are another two Russian proposals and a South Korean one.

Note.

  1. There are some large numbers.
  2. There are also some huge ambitions and massive budgets.

But will we ever see large scale tidal power stations?

Could The Morocco-UK Power Project Be Developed Into A Western Europe And Africa Interconnector?

This page on the Xlinks web site, describes the Morocco-UK Power Project, which is proposed to generate solar and wind power in Morocco and deliver it to the UK.

  • The plan envisages 10.5 GW of electricity being generated.
  • There will be a 5GW/20GWh battery in Morocco.
  • They will export 3.6 GW of electricity to the UK for at least twenty hours per day.
  • The electricity will be exported to the UK by an Interconnector that skirts to the West of Spain, Portugal and France.
  • The interconnector will be 3,800 kilometres long.

I described the project in detail in Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project.

This Google Map shows Western Europe And North Africa.

Note.

  1. The light blue of the Continental Shelf
  2. The darker blue of deeper water.
  3. The Southern end of the Morocco and the UK interconnector will at Guelmim Oued Noun in the South of Morocco, which is indicated by the red arrow.
  4. The UK end of the cable will be at Alverdiscott between Barnstaple and Bideford in North Devon.
  5. Southern Morocco and Algeria look to be mainly in the Sahara Desert.

If we look at the route of the cable, it connects a lot of possible renewable energy sources.

  • Morocco – Solar and wind
  • Spain – Solar and wind
  • Portugal – Solar and wind
  • France – Nuclear, tidal and wind
  • UK – Nuclear and wind.

Could the UK and Morocco interconnector be developed into a bigger power project?

  • Solar and wind power from Algeria could be added.
  • Tidal power from a Severn Barrage could be added.
  • Connections could be added to Gibraltar, the Irish Republic and Wales.

I believe that there could be a large amount of electricity developed on the Western costs of Europe and Africa.

An interconnector would move it to where it is needed.

Newport To London Electric Railway Is Completed

The title of this post, is the same as that of this article on the South Wales Argus.

This is the introductory couple of paragraphs.

Railway works to improve the line between Newport and London will allow for more frequent and quicker journeys, said to the boss of Network Rail.

Electrification works have now been completed on the Severn Tunnel, meaning the line from Cardiff and Newport to London Paddington is now fully electric.

The article also states that the Sudbrook pumping station, which pumps fourteen million gallons of water out of the Severn Tunnel every day is to be replaced.

The Severn Tunnel has been a project, which has involved lots of heroic engineering.

When I read articles like the one in the South Wales Argus, I am drawn back to the briefing I had from engineers at Sir Frederick Snow and Partners about their plan for a Severn Barrage, in the early 1970s.

It was a One-Design-Solves-Everything project and their plan, included a high speed railway and a motorway crossing between England and Wales.

Sizewell C: Nuclear Power Station Plans For Suffolk Submitted

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

A few points from the article.

  • It will provide enough electricity for six million homes.
  • It will create 25,000 jobs during construction.
  • Sizewell C will be a near replica to Hinckley Point C.
  • It will generate 3.2 GW of electricity.
  • It will be low-carbon electricity.

As a well-read and experienced engineer, I am not against the technologies of nuclear power.

But I do think, by the time it is completed , other technologies like wind and energy storage will be much better value. They will also be more flexible and easier to expand, should we get our energy forecasts wrong.

  • We will see higher power and more efficient wind farms, further out in the North Sea.
  • Massive energy storage systems, based on improved pumped storage technology and using new technology from companies like Highview Power, Zinc8 and others will be built.
  • Wind and solar power an energy storage are much easier to fund and financial institutions like L & G, Aberdeen Standard and Aviva have invested in the past for our future pensions.
  • If you want to go nuclear, small modular reactors, look to be much better value in the longer term.
  • I also don’t like the involvement of the Chinese in the project. History tells me, that all pandemics seem to start in the country!

It is my view that the biggest mistake we made in this country over energy was not to built the Severn Barrage.

My preferred design would be based on the ideas of Sir Frederick Snow.

There would have been a high and a low lake, either side of a central spine, behind an outer barrage.

  • Reversible turbines and pumps between the lakes would both generate and store electricity.
  • When proposed in the 1970s, it would have generated ten percent of the UK’s electricity.
  • A new road and rail crossing of the Severn, could have been built into the outer barrage.
  • A lock would have provided access for shipping.
  • It would have controlled the periodic, regular and often devastating flooding of the River Severn.

Some versions of the original design, even incorporated an international airport.

  • The runways would be in the right direction for the prevailing wind, with regard to take-off and landing.
  • Take-off would be over open sea.
  • High speed trains could speed travellers to and from London on an updated Great Western Railway.

I believe a modern design could be even better.

  • The central spine and the outer barrage would be the foundations for a large wind farm.
  • There would also be a large number of powerful floating wind turbines to the West of the outer barrage in the Severn Estuary.
  • A giant electrolyser on the central spine would produce hydrogen, that could be used to decarbonise the UK’s gas network.
  • A power interconnector could be built into the outer barrage to connect Wales to the nuclear power stations at Hinckley :Point.
  • A cluster of small nuclear reactors could be built on the central spine.
  • In the intervening fifty years, we have probably learned how to build a barrage like this, so that it can benefit birds and other wildlife.

I believe, it will never be too late to build a Severn Barrage.

M4 Relief Road: Five Things The Planning Inspector Said

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

This is two of the introductory paragraphs.

Until First Minister Mark Drakeford cancelled it, despite the conclusions of a planning inspector.

After months of studying the evidence in a public inquiry, Bill Wadrup said there was a “compelling case” to build the relief road.

I have read a lot about this relief road and something definitely needs to be done to ease the problems of going between England and South Wales.

On the one hand my environmental and non-driving thoughts, lead me to conclude that the road shouldn’t be built and more transport should be transferred to rail.

But on the other hand, my economic thoughts say that it should be built.

What Happens Now?

In this second article on the BBC, this is said about the stance of the various politicians.

The plans have proved politically divisive too – there has been significant opposition in Labour and some ministers are thought to oppose the scheme.

Plaid Cymru is firmly against, while the newly-formed Brexit Party is backing the road.

Some Labour Newport politicians – particularly those from the Newport West constituency – have lobbied for the road to be built.

Labour AM Jayne Bryant said: “Air pollution is a serious public heath issue because of the congestion on the M4.

“The vast amount of traffic on the M4 around Newport is not local to Newport – that’s why public transport alone will not solve it.”

Plans for the scheme were revived in 2013 after the UK government offered borrowing powers that would allow for the upgrade.

Former Prime Minister David Cameron called the Brynglas tunnels “a foot on the windpipe of the Welsh economy” – and the UK government remains a supporter of the scheme.

Economics could mean that a new Welsh Government, will change their mind. Especially, if the M4 relief road becomes an election issue.

As I write this, news is expected of the closure of Ford’s Bridgend factory.

I doubt this is down to the state of the M4, but getting trucks to and from South Wales will become an increasing logistics nightmare. It may mean, that businesses thinking of setting up a Welsh factory will look elsewhere.

The Railway Must Be Key

The only alternative to the M4 is to make more use of the railway.

The Welsh Government is planning the following.

  • An extensive South Wales Metro, with new routes, trains and some new stations.
  • More Park-and-Ride stations on the South Wales Main Line.
  • Extension of Cardiff station.

But is it enough?

Probably not!

  • Does the double-track Severn Tunnel have enough capacity for all the trains to and from a hopefully-expanding Welsh economy?
  • Can freight trains get easily to and from the Channel Tunnel, Felixstowe, Liverpool, London and Southampton?
  • Is the rail route for travellers between South Wales and Heathrow an incentive to drive?
  • Are services between South Wales and Birmingham and Manchester a joke?

A lot of money needs to be spent!

And much of it in England not Wales!

Frederick Snow Was Right

In The Severn Barrage, I wrote about Frederick Snow’s plan for a tidal power station and airport in the Severn Estuary, based on a barrage.

I believe that if the Severn Barrage had been build correctly in the 1970s, that a new Southern M4 and rail route could have been built on top of the barrage.

Conclusion

It’s a mess!

In my view the most likely solution will be that traffic on the M4 gets so bad, that travellers and freight will move or get moved to rail.

The Beginning Of A New Era

These words come from a the Head of Control Room Operations at National Grid in this article on the BBC, which is entitled UK achieves solar power record as temperatures soar.

This is the first two paragraphs of the article.

A record amount of solar power was generated on Friday as Britain basked in sunshine and temperatures of up to 28C, the National Grid has said.

It said 8.7 gigawatts (GW) had been generated at lunchtime, representing 24.3% of total generation across the UK.

When I was growing up in the 1960s, solar power was seen in pictures of space satellites and probes, but I can’t ever remember anyone saying that fifty years later, the UK would be generating around a quarter of its power from the sun.

I think it could be a case of you ain’t seen nothing yet!

Consider.

  • The big development will be batteries, which will mean that micro-generators will be able to store their power for later use.
  • I also suspect that the proportion of UK solar power generation will rise due to the fall in the price of solar panels and the rise in their generating efficiency.
  • There will be new forms of solar panels, like these solar slates for use on traditional buildings or in conservation areas.
  • In a few years time, all large industrial buildings like farm barns, factory units and retail sheds will be built or retro-fitted with solar roofs.

Never underestimate the ingenuity of engineers and scientists, especially if there is money to be made in an ethical way.

We will still need to generate some electricity in conventional ways to fill in the gaps, when the wind isn’t blowing, the sun isn’t shining and it’s between the tides.

There will be some nuclear and probably some gas-powered stations. The former are generally good for constant load and the latter have the advantage, that they can be brought on stream quickly. Try doing that with a large coal or bio-mass powered power station.

We also have a need for more energy storage like Dinorwig in Wales. This massive system was built in the 1970s and has a lot of advantages including.

  • It will be operational for centuries.
  • It has a very high efficiency.
  • Once built it is zero carbon.
  • It has become a tourist attraction.
  • It is an ideal partner to wind and solar power.

We need more electric mountains.

Sir Frederick Snow’s plan for barraging the River Severn with a high and low lake separated by a central spine, was designed to incorporate energy storage.

It is a tragedy, that we do not make use of the massive amounts of free power in the Severn Estuary.

The Severn Barrage Is Still Off The Agenda

I have just seen this story and video on the BBC’s web site.

It shows the terrible state of the River Severn and the surrounding land.

One of my earliest memories is the aftermath of the East Coast Floods of 1953. Since then, every year or so the River Severn floods badly and despite barriers in other places like the rivers Thames, Tees and Hull, nothing of a similar scale has been done to alleviate the problems on the Severn.

I worked at Frederick Snow and Partners in the 1970s and was told of their design for a proposed Severn Barrage, that would help to cut flooding and also generate ten percent of our electricity.

Surely now is the time to build such a structure!

Will We Get A Tidal Power Station At Swansea?

I ask the question after reading about the proposed Swansea Bay Tidal Lagoon in the Sunday Times.

I like it, as it doesn’t have the problems of one of my favourite energy developments; the Severn Barrage.

It would appear to be fairly simple, have a sound economic case, the backing of the locals and doesn’t seem to annoy those that love birds more than energy.

It also has some other advantages.

If it works, it can serve as a prototype for other schemes around the UK and the world.

They don’t say whether the sea wall could be used to support wind turbines and whether the generators could be reversed to create some pumped storage facility, but on a quick perusal of the project, it could be an ideal platform on which to mount other zero carbon technologies.

Carbon Capture And Storage

I went to the Geological Society yesterday to see a presentation by Paul Garnham of Shell about Carbon Capture and Storage and Shell’s project to implement it on Peterhead Power Station. The lecture is here on the Geological Society web site and a video will be uploaded in a few days.

I knew little about carbon capture and storage or CCS, a few weeks ago, but now after the excellent lecture and some reading, I know a little more. But only a very little!

So have I come to any conclusions?

I haven’t altered my major idea, that the first thing we must do is use a lot less energy and especially that produced by burning fossil fuels in one way or another.

But CCS seems to be one of those crazy ideas, thought up by politicians and oil companies, so they can say, they’re doing something to stop the rise in energy prices. My thoughts turn to King Canute on the beach trying to get the sea to obey him.

I may be proved wrong on CCS, but I object to funding crazy ideas like this, the importation of wood chip and the building of useless wind turbines, when we could do sensible things like insulate houses and other buildings, properly barrage the Severn Estuary, build several nuclear power plants and even use fracking in the short term, until nuclear comes on stream.,

We don’t have an energy policy in this country, but a scientifically incorrect policy to put the lights out.

At least then, with no electricity, we won’t be able to do anything that uses energy!

Another Letter in The Times

I had another letter published in The Times yesterday about the Severn Barrage.

Sir, Paul Knight (letter, May 19) may well be right, if the Severn Barrier is built across the estuary, as is currently proposed. In the 1960s Sir Frederick Snow suggested that the river should be divided into a high and a low lake by a spine between containing the turbines and pumps, which would also have stored energy, by pumping water from the low to high lakes. I believe that this arrangement would be much more favourable to salmon and trout, as fish ladders and gates could be built at the upstream end.

My original letter is here.

I’m now coming to the conclusion, that the Severn Barrage, may well be the way to create a large amount of renewable energy. I doubt though, that it will ever be built, those who feel it shouldn’t be built have too many votes and will win through fear of the ballot box.

I think now, if the government were to propose a Channel Tunnel to connect England to France, it would not get built. Voters would have scrapped the Olympics too, if they’d have a chance.
