MAN Energy Partners With Highview Power On Liquid-Air Energy-Storage Project

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

This is the introductory paragraph.

Highview Power, a leader in long duration energy storage solutions, has selected MAN Energy Solutions to provide its LAES turbomachinery solution to Highview Power for its CRYOBattery™ facility, a 50 MW liquid-air, energy-storage facility – with a minimum of 250MWh – located in Carrington Village, Greater Manchester , U.K.

The article is almost a word-for-word copy of this press release from MAN Energy Solutions, which has a similar title to this post and the Renewable Energy Magazine article.

As an Electrical Engineer who has done a lot of work in Project Management, I find these two paragraphs significant.

Construction will proceed in two phases. Phase 1 will involve the installation of a ‘stability island’, to provide near-instantaneous energy grid stabilisation. This will be achieved using a generator and flywheel, among other components. Enabling short-term stabilisation will provide the basis for Phase 2 and the completion of the more complex liquid air energy storage system that includes various compressors, air expanders and cryogenic equipment.

Phase 2 will represent the integration of stability services with a full-scale long-duration energy storage system, and in doing so promote the full integration of renewable energy. The Carrington project will offer a blueprint for future projects and cement the partnership between MAN Energy Solutions and Highview Power.

I first became acquainted with the use of flywheels to stabilise energy, when I was working in Enfield Rolling Mills as a vacation job at sixteen.

The centerpiece of their factory was a rolling mill, which took heated copper wirebars about two metres long  amd ten centimetres square and rolled them into thick copper wire just a few millimetres in diameter. The mill was driven by a powerful electric motor, to which it was connected with a 97 tonne flywheel perhaps four metres in diameter in between. The flywheel spun at probably 3000 revolutions per minute.

The wirebar used to meander through the rolling mill several times and at each turn, the head would be caught by a man with a pair of tongs and turned back through the mill.

Each time the wire-bar went through a new pair of rolls the energy needed increased, as there was more rolling to do. So this extra energy was taken from the flywheel!

The rolling mill incidentally had been built by Krupp before the First World War. It still had the Krupp trademark of three interlocked railway tyres all over it. It had ended up in Enfield as reparations after the First World War. Enfield Rolling Mills added a fourth ring to create their own trademark.

It would appear that the kinetic energy of that flywheel could be as high as 1.6 MWh. Flywheels also react very fast.

Flywheel energy storage would appear to be a feasible intermediate energy store for this type of application.

I always remember Shimatovitch, who was the Chief Engineer of the company had jokingly once said that if the flywheel came off its bearings, it would have ended up a couple of miles away and would have demolished all the houses in its path. But he was a man with a dark sense of humour, who had spent most of the Second World War in a Nazi concentration camp.

Could it be that Phase 1 is the installation of a similar system to that I saw working in the 1960s, but upgraded with modern electronics, which exchanges power with the grid to create the stability island referred to in the press release.

In Phase 2 electricity can be passed to and from the CRYOBattery.

Looking at the MAN Energy Solutions web site, I suspect that they don’t care what sort of energy store they connect to the grid.

They would appear to be an excellent choice of engineering partner for Highview Power.

I also wonder how many other applications and customers, they will bring into the partnership.

Conclusion

This looks like a very sensible and low-risk strategy to connect the CRYOBattery to the grid.

Highview Power Begins 2021 With 4 GWh Of CRYOBattery Storage In Global Pipeline

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

Read the article to find out how Highview Power are progressing with partners, offices and projects all over the world.

Not bad for an idea, that was invented in a garage in Bishops Stortford.

The article points to this video produced by the BBC.

If there’s one new venture, I wish I’d have a share of, it is this one.

  • One of the projects, I worked on at ICI was optimising the size of a new plant to make plastic granules. I learned a great deal about how process plants can be scaled and their mathematics and economics.
  • I believe that Highview Power’s CRYOBaterries fit with everything I know and are just world-class process engineering arranged in a unique way, which means they can be built in any country, where modern process plant technology is available and can be run and serviced by skilled engineers and technologists.
  • Their partnership with the likes of Sumitomo Heavy Industries means, Highview Power, probably has access to the best technology, for some of the components needed.

After reading the article in Solar Builder, I now feel that Highview Power are on their way!

One of the first places, I shall visit after lockdown ends is Carrington near Manchester, to take pictures of the site of Highview Power’s 50 MW/250 MWh system, that is being built at Carrington.

Highview Power Breaks Ground on 250MWh CRYOBattery Long Duration Energy Storage Facility

The title of this post, is the same as that of this News page on the Highview web site.

The page shows this picture of diggers doing, what they do.

Note the two towers in the background of the image on the right. They look like the towers of Carrington power station, which are shown on this page on the FK Group web site, who built the 884 MW CCGT power station.

This Google Map shows the site of the power station.

On a larger scale map, you can pick out the towers from their shadows and it looks to me, that Highview’s 250MWh CRYOBattery is being built on the vacant site to the South of the power station.

Consider.

  • The vacant site looks large.
  • I’ve read somewhere that Highview’s CRYOBatteries are expandable by adding more tanks.
  • They certainly have space to add lots of extra tanks and a 884 MW power station on the doorstep to fill them.
  • All the heavy equipment and components to build Carrington power station were brought in by barge using the River Mersey and the Manchester Ship Canal. Will this method be used again?

This seems to be a site that would be ideal for a very large battery.
