SSE Goes Global To Reap The Wind

The title of this article on This Is Money is Renewable Energy Giant SSE Launches Plan To Become Britain’s First Global Windfarm Business As it Invests Up To £15bn Over Next Decade.

The title is a good summary of their plans to build wind farms in Continental Europe, Denmark, Japan and the US, in addition to the UK and Ireland.

I can also see the company developing more integrated energy clusters using the following technologies.

  • Wind farms that generate hydrogen rather than electricity using integrated electrolysers and wind turbines, developed by companies like ITM Power and Ørsted.
  • Reusing of worked out gasfields and redundant gas pipelines.
  • Zero-carbon CCGT power stations running on Hydrogen.
  • Lots of Energy storage.

I talked about this type of integration in Batteries Could Save £195m Annually By Providing Reserve Finds National Grid ESO Trial.

In the related post, I talked about the Keadby cluster of gas-fired power stations, which are in large part owned by SSE.

Conclusion

I think that SSE could be going the way of Equinor and Ørsted and becoming a global energy company.

It is also interesting the BP and Shell are investing in renewable energy to match the two Scandinavian companies.

Big Oil seems to be transforming itself into Big Wind.

All these companies seem to lack grid-scale energy storage, although hydrogen can be generated and stored in worked-out gas fields.

So I would expect that some of the up-and-coming energy storage companies like Gravitricity, Highview Power and RheEnergise could soon have connections with some of these Big Wind companies.

Crown Estate’s Auction Of Seabed For Wind Farms Attracts Sky-High Bids

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

This is the opening paragraph.

An auction of seabed rights to build offshore wind farms around England and Wales has attracted frenzied bidding that could be worth hundreds of millions of pounds a year to the Treasury and the Queen.

I don’t find this surprising.

Bigger Seems Better Offshore

Wind turbine technology is getting better and much larger. It also seems that the new larger floating turbines are much more efficient and generate power for a greater proportion of the day.

My project management software helped to harvest North Sea Oil and I have been told by many in the industry, that North Sea Oil really took off when platforms and the equipment like cranes used to build them got truly enormous.

I feel, we could be seeing the same size effect happening as we harvest the wind!

Hydrogen And Wind Power

The latest development is not to generate electricity, but to use it in the turbine to generate hydrogen, which is then piped to the shore.

  • The UK Government is funding this technology in part with a grant to ITM Power.
  • I wrote about the technology in ITM Power and Ørsted: Wind Turbine Electrolyser Integration.
  • Existing gas networks can be reconfigured to bring the hydrogen to the shore.
  • Piping hydrogen costs less than cabling electricity.
  • Hydrogen networks are being built at several places in the UK, to fuel homes, power stations and industry like steel-making and petrochemicals.

Could all this explain Big Oil’s involvement?

Do they want to exchange fossil fuels for green hydrogen?

They certainly know how to distribute it.

Energy Storage

For my own investments, I’m looking at energy storage, where the UK has at least three promising new ideas, all of whom have had Government grants.

  • Gravitricity
  • Highview Power
  • ReEnergise

The Government has also indirectly-backed Cornish Lithium

Spot The Battery

RheEnergise have just released this picture, of one of how one of their pumped storage systems might look.

They describe it as a typical small site after landscaping.

This is their description of the image.

This is an image of a small water works in Fife Scotland, you can just see 2 small water tanks at the base of the hill. This is an example of what a small High-Density Hydro project could look like after landscaping.

How many times have you seen a scene like this in the UK, Europe and all over the world.

They didn’t disclose the storage capacity of this system.

Holy Grail Of Energy Storage Receives Two Grants

The title of this post, is the same as that of this article on Off Grid Energy Independence.

This is the introductory paragraph.

RheEnergise is one of only a select handful of businesses to have been awarded grants under both the Sustainable Innovation Fund & the Small Business Research Initiative.

So what have RheEnergise developed?

The home page of their web site, is surprisingly detailed, unlike those of some other companies with new ideas, and not just energy storage companies!

This is the first paragraph on their home page.

RheEnergise is bringing innovation to pumped hydro storage. We call our new solution High-Density Hydro ™.

I think that is a good start, as although pumped hydro storage is well proven and the UK has the 1,728 MW Dinorwig Power Station, which has a storage capacity of 9.1 GWh, building new large pumped storage systems is fraught with difficulties and the technology has seen only modest innovation in the last few decades.

The next paragraph on their home page describes their innovation.

HD Hydro ™ uses our proprietary HD Fluid R-19 ™, which has 2.5x the density of water. R-19 gives RheEnergise projects 2.5x the power and 2.5x the energy when compared to water.

This means that for the same size of pumped hydro storage power station, you get 2.5 times the amount of energy storage.

Alongside a diagram of the system, the advantages of their systems is stated.

Projects can be installed on hills 2.5x lower than a project using water and still achieve the same power – for example, there are so many more hills at 150m than at 375m.

2.5x smaller, by volume, meaning dramatically lower construction costs, faster build times, easier reinstatement and easier landscaping – projects can be entirely hidden.

A very simple innovation has greatly increased the possibilities of pumped hydro storage.

The home page also gives a typical capacity.

RheEnergise projects provide 10MW to 50MW power and 2 to 10 hours of storage capacity.

These systems are in the same range as those of Highview Power, who are building a 50 MW system, with a five hour capacity at Carrington near Manchester, that I wrote about in Highview Power Breaks Ground on 250MWh CRYOBattery Long Duration Energy Storage Facility.

Both have the advantage, that they are easily scalable.

With RheEnergise’s HD Hydro ™, the size of the upper reservoir would need to be increased and with Highview Power’s CRYOBattery, more tanks for the liquid air would need to be added.

The Technology

I certainly agree with the principle behind ReEnergise, both mathematically and practically.

My interest scientifically, is what is the fluid they use?

  • Pure water has a specific gravity of one and everything else is measured with respect to this.
  • So aluminium, which has a specific gravity of 2.7, is 2.7 times as heavy as water.
  • Many of us will be familiar with mercury, which is a metal, that is liquid at room temperature.
  • Mercury has a specific gravity of 13.56.

It puzzles me, how someone has created a liquid, almost as heavy as aluminium, that can be pumped and handled like water, as it would need to be, to make a pumped storage system work.
