The Anonymous Widower

EuroLink, Nautilus And Sea Link

EuroLink, Nautilus and Sea Link are three proposed interconnectors being developed by National Grid Ventures.

EuroLink

EuroLink has a web site, where this is said.

To support the UK’s growing energy needs, National Grid Ventures (NGV) is bringing forward proposals for a Multi-Purpose Interconnector (MPI) called EuroLink, which will deliver a new electricity link between Great Britain to the Netherlands. 

EuroLink could supply up to 1.8 gigawatts (GW) of electricity, which will be enough to power approximately 1.8 million homes, as well as contribute to our national energy security and support the UK’s climate and energy goals. We’re holding a non-statutory public consultation to inform you about our EuroLink proposals, gather your feedback to help refine our plans and respond to your questions.​

Note, that EuroLink is a Multi-Purpose Interconnector (MPI) and they are described on this page of the National Grid website.

In EuroLink’s case, this means it is basically an interconnector between the UK and The Netherlands, that also connects wind farms on the route to the shore.

  • Coastal communities get less disruption, as the number of connecting cables coming ashore is reduced.
  • Less space is needed onshore for substations.
  • Electricity from the wind farms can be directed to where it is needed or can be stored.

As an Electrical and Control Engineer, I like the MPI approach.

The technology to implement the MPI approach is very much tried and tested.

There are many references to EuroLink terminating at Friston.

Nautilus

Nautilus has a web site, where this is said.

Nautilus could connect up to 1.4 gigawatts (GW) of offshore wind to each country through subsea electricity whilst connecting to offshore wind farm/s at sea. By combining offshore wind generation with interconnector capacity between the UK and Belgium, Nautilus would significantly reduce the amount of infrastructure and disruption required both onshore and offshore.

With this new technology, we hope to reduce the impact of infrastructure on local communities and the environment, as well as support the government’s net zero and energy security targets. We are already working closely with other developers in the area to coordinate activities and minimise impact on local communities. We believe that through improved coordination, the UK government can achieve and support the co-existence of renewable energy with coastal communities.

Nautilus is another MPI.

This is said on the web site.

Last year, National Grid Ventures ran a non-statutory consultation for Nautilus, which proposed a connection at Friston.

NGV holds a connection agreement on the Isle of Grain in Kent as part of its development portfolio and we are currently investigating if this could be a potential location for Nautilus. Until this is confirmed to be technically feasible, Nautilus will be included as part of our coordination work in East Suffolk.

So it looks like, Nautilus could connect to the UK grid at Friston or the Isle of Grain.

Sea Link

Sea Link has a web site, and is a proposed interconnector across the Thames Estuary between Suffolk and Kent.

This is said on the web site about the need for and design of Sea Link.

The UK electricity industry is evolving at pace to help lead the way in meeting the climate challenge, whilst also creating a secure energy supply based on renewable and low carbon technologies.

The demands on the electricity network are set to grow as other sectors of the economy diversify their energy consumption from using fossil fuels towards cleaner forms, the move towards electric vehicles being just one example.

Where we’re getting our power from is changing and we need to change too. The new sources of renewable and low-carbon energy are located along the coastline. We need to reinforce existing transmission network and build new electricity infrastructure in these areas in order to transport the power to where it’s needed. This is the case along the whole of the East Coast including Suffolk and Kent.

To allow this increase in energy generation, we need to reinforce the electricity transmission system. Sea Link helps to reinforce the electricity network across Suffolk and Kent.

Our proposals include building an offshore high voltage direct current (HVDC) link between Suffolk and Kent with onshore converter stations and connections back to the national electricity transmission system.

On the web site, in answer to a question of What Is Sea Link?, this is said.

Sea Link is an essential upgrade to Britain’s electricity network in East Anglia and Kent using subsea and underground cable. The proposal includes approximately 130km of subsea cables between Sizewell area in East Suffolk and Richborough in Kent. At landfall, the cables would go underground for up to 5 km to a converter station (one at each end). The converter station converts direct current used for the subsea section to alternating current, which our homes and businesses use. A connection is then made to the existing transmission network. In Suffolk, via the proposed Friston substation; in Kent via a direct connection to the overhead line between Richborough and Canterbury.

Note, that from Kent electricity can also be exported to the Continent.

All Cables Lead To Friston In Suffolk

It looks like EuroLink, Nautilus and Sea Link could all be connected to a new substation at Friston.

But these will not be the only cables to pass close to the village.

This Google Map shows the village.

Running South-West to North-East across the map can be seen the dual line of electricity pylons, that connect the nuclear power stations at Sizewell to the UK electricity grid.

Has Friston been chosen for the substation, so that, the various interconnectors can be connected to the power lines, that connect the Sizewell site to the UK electricity grid.

This would enable EuroLink, Nautilus and/or Sea Link to stand in for the Sizewell nuclear stations,  if they are shut down for any reason?

It does appear from reports on the Internet that the Friston substation is not welcome.

Exploring Opportunities For Coordination

The title of this section is a heading in the EuroLink web site, where this is said.

In response to stakeholder feedback, NGV’s Eurolink and Nautilus projects and NGET’s Sea Link project are exploring potential opportunities to coordinate. Coordination could range from co-location of infrastructure from different projects on the same site, to coordinating construction activities to reduce potential impacts on local communities and the environment.

That sounds very sensible.

UK Govt Awards Almost GBP 33m To Innovative Energy Storage Projects

The title of this post is the same as that of this article on Renewables Now.

This is the first paragraph.

The UK government has awarded GBP 32.9 million (USD 39.7m/EUR 38.3m) in funding to five innovative energy storage projects under the second phase of its Longer Duration Energy Storage competition.

These are the projects.

StorTera

StorTera has secured GBP 5.02 million to create a prototype demonstrator of its single liquid flow battery (SLIQ) technology.

The company’s main product is the SLIQ Flow Battery, for which it gives the headline of Reliable, Economical Energy For 20 Years.

This is a description of the technology.

The revolutionary StorTera SLIQ single liquid flow battery offers a low cost, high performance energy storage system made with durable components and supported by our flexible and adaptable inverter and control system. The StorTera SLIQ battery brings the following benefits/advantages:

  • Low levelised cost of storage and capital cost
  • Long lifetime of up to 20 years (min. 7,500 cycles)
  • Long duration energy with the energy and power capacity easily and independently scalable
  • Safe with no cooling requirements and high flash point materials
  • Fully recyclable at the end of lifetime

This is said about costs – Using low cost materials and manufacturing techniques, we predict capital costs of approximately £120/kW and £75/kWh by 2022.

I feel there could be something about this technology, but we’ll only know, when the demonstrator is fully working.

Sunamp

Sunamp will get GBP 9.25 million to test its thermal storage system in 100 homes across the UK.

On their home page, Sunamp has a banner of World Leading Thermal Technologies, with this description underneath.

Sunamp designs and manufactures space-saving thermal storage that makes UK homes, buildings and vehicles more energy-efficient and sustainable, while reducing carbon emissions and optimising renewables.

They do appear to have sold something, which is always a useful thing to do.

This page on their web site,  describes their Thermino Thermal Storage For Domestic Hot Water, where this is said.

Thousands of Sunamp thermal batteries are already in homes across the UK storing heat from low-carbon energy sources and releasing it for mains-pressure hot water when needed.

Our Thermino batteries replace traditional hot water cylinders – direct (for grid electricity and solar PV) or indirect (for boilers and heat pumps).

They are up to four times smaller than the equivalent hot water tank because they are filled with our energy-dense phase change material, Plentigrade. This means that heat pump systems can be installed where otherwise they wouldn’t fit, for example.

The key seems to be this substance called Plentigrade!

This page on their web site describes Plentigrade.

Under a heading of Storing Energy As Heat And Releasing It When, And Where, It’s Needed, this is said.

Sunamp thermal batteries are energy-saving thermal stores containing Plentigrade: our high-performance phase change materials (PCMs) that deliver heating or cooling reliably, safely and efficiently.

Plentigrade, with its perpetual phase changing ability, is at the core of our products.

Our breakthrough technology was created in collaboration with the University of Edinburgh, ranked among the top 20 universities in the world, and the UK’s national synchrotron particle accelerator, Diamond Light Source. To find out more about the chemistry behind Plentigrade, read our blog.

Note.

  1. This product almost looks to be too good to be true.
  2. But I’ve checked and it doesn’t seem to have appeared on Watchdog.
  3. It’s yet another breakthrough, that has used the Diamond Light Source.
  4. How many other developments would happen with a Diamond 2 in the North, as I wrote about in Blackpool Needs A Diamond?

I have a feeling, that my house needs one of Sunamp’s thermal batteries.

University of Sheffield

The article says this about a grant to the University of Sheffield.

The University of Sheffield has been awarded GBP 2.6 million to develop a prototype modular thermal energy storage system designed to provide optimised, flexible storage of heat within homes.

There are several thermal batteries around for houses.

RheEnergise

The article says this about a grant to RheEnergise.

With a GBP-8.24-million grant, RheEnergise Ltd will build a demonstrator of its High-Density Hydro pumped energy storage system near Plymouth. The technology uses a fluid denser than water to generate electricity from gentle slopes.

I wrote about this in Plan For £8.25m Plymouth Energy Plant To Generate Power From Cream-Like Fluid.

EDF UK R&D

The article says this about a grant to EDF UK R&D.

The government is also backing with GBP 7.73 million an initiative of EDF UK R&D and its partners, the University of Bristol, Urenco and the UK Atomic Energy Authority (UKAEA), to develop a hydrogen storage demonstrator using depleted uranium at UKAEA’s Culham Science Centre in Abingdon, Oxfordshire.

I wrote about this in Innovative Hydrogen Energy Storage Project Secures Over £7 million In Funding.

Conclusion

They are a mixed bunch of ideas from around the UK, that I think will produce at least two good winners.

Toyota To Build Hydrogen Fuel Cell Trucks In UK

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

These are the first two paragraphs.

The UK’s first mainstream commercial vehicle to be powered by hydrogen fuel cells will be built at the Toyota plant in Derbyshire, holding out the prospect that the Japanese group will choose Britain as its European manufacturing centre for the next-generation zero-emission technology.

Toyota will announce today that it has chosen Burnaston to produce six prototype hydrogen versions of its popular Hilux pick-up trucks.

It may be only a few vehicles initially, but if Toyota choose Burnaston, as their European manufacturing centre for the next-generation zero-emission technology, this could be large.
