Developer 8minute Says More Than 24GWh Of Batteries Included In Its US Solar-Plus-Storage Pipeline
The title of this post, is the same as that of this article on Energy Storage News.
What caught my eye was the 24 GWh!
When you consider that the biggest battery in the UK is Electric Mountain, which has a capacity of 9 GWh, 24 GWh of batteries is a large number!
It will need a lot of solar panels to keep that amount of batteries brim-full.
This is a sentence from the article.
The company’s projects include the Eland Solar & Storage Center, which will comprise 400MWac of PV and 300MW / 1,200MWh of battery energy storage, currently under construction in California’s Mojave Desert.
Those are big numbers against the UK’s largest solar park at Shotwick in Wales, which is just 72.2 MW.
Portugal’s Delayed 700MW Solar Tender With Storage Option Launches
The title of this post, is the same as that of this article on Energy Storage News.
According to the Wikipedia entry for Solar Power in Portugal, Portugal had 828 MW of installed solar power in 2018.
So 700 MW will almost double the capacity.
Note that if they had the same amount of installed solar power per square mile as the UK, Portugal would have 3 GW or 3,000 MW of installed solar power.
Newcomer Broad Reach Power To Deploy Increasingly Large Battery Systems In Texas
The title of this post is the same as that of this article on Energy Storage News.
This is the introductory paragraph.
US-based independent power producer (IPP) Broad Reach Power has said it will build 15 projects in Texas in 2020, each of them just under 10MW / 10MWh, with construction on six of them set to begin this summer.
The article then goes on to describe the electricity industry in Texas and where the battery storage fits in.
It’s all a far cry from the Texas portrayed in soaps like Dallas.
Wind Power In Texas
Wind Power in Texas has its own Wikipedia entry and this is the first paragraph.
Wind power in Texas consists of over 40 wind farms, which together have a total nameplate capacity of over 28,000 MW (as of 2019). If Texas were a country, it would rank fifth in the world: The installed wind capacity in Texas exceeds installed wind capacity in all countries but China, the United States, Germany and India. Texas produces the most wind power of any U.S. state.
But then everything in Texas, is famed as being the biggest in the world.
Their installed capacity of 28 GW compares with 17.64 GW of installed wind power in the UK.
Solar Power In Texas
Solar Power in Texas also has its own Wikipedia entry and this is the first paragraph.
Solar power in Texas, along with wind power, has the potential to allow Texas to remain an energy-exporting state over the long term. The western portion of the state especially has abundant open land areas, with some of the greatest solar and wind potential in the country. Development activities there are also encouraged by relatively simple permitting and significant available transmission capacity.
The Wikipedia entry also says that in 2019, Texas had 4.32 GW of installed solar power.
By comparison, the UK has 8.1 GW of installed solar power. Who’d have thought that?
As Texas is 2.87 times geographically larger than the UK, if Texas had the same solar panel density as the UK, Texas would have an installed capacity of 23.2 GW.
The Need For Energy Storage In Texas
With all this installed wind and solar energy in Texas and its potential for expansion, there would appear to a massive demand for energy storage in the state.
Conclusion
What would JR think?
Britain Goes Coal-Free For Two Months – Longest Period Since Industrial Revolution
The title of this post, is the same as that of this article in The Independent.
This is the introductory paragraph.
Britain is on course to pass an energy milestone as it reaches two months of coal-free power generation on Wednesday – the longest period the country has gone without using the fossil fuel since the industrial revolution.
It is partly due, to a lack of electricity demand due to COVID-19, but overall it is a good thing.
As I write this at 14:30 on the 9th June 2020, UK Electricity Production gives the various sources of production as follows.
- Biomass – 3,045 MW
- CCGT – 17,442 MW
- Hydroelectric – 217 MW
- Interconnects – 1,977 MW
- Nuclear – 4,229 MW
- Other – 75 MW
- Pumped Storage – 0 MW
- Solar – 4,800 MW
- Wind – 697 MW
This all adds up to a total of 32.42 GW.
Note.
- CCGT stands for combined cycle gas turbine.
- Solar power is generating more than nuclear.
- I don’t think today is a very windy day!
I have just used the site to look at a few solar farms in Kent. Most seem to be generating 14.8 % of their capacity.
Understanding Floatovoltaics
Floatovoltaics is mounting panels on floats, on an appropriate stretch of water.
This video, which I think from some of the words in the commentary, is shown to visitors who visit the floating solar farm at Yamakura Dam.
It describes all the advantages of floating solar and shows how this 13.7 MW solar farm was constructed.
We’ve even got a couple of these floating solar farms in the UK.
This Google Map shows the farm in the Queen Elizabeth II Reservoir, near Walton-on-Thames.
There is also this article in the Guardian, which is entitled World’s Biggest Floating Solar Farm Powers Up Outside London. It gives a good description of the project.
The article also states that unlike large solar arrays on land, no planning permission is required.
United Utilities have also installed a system at Godley Reservoir in Hyde, near Manchester, as this Google Map shows.
They must like the first installation, as this Press Release from United Utilities indicates that they are now building a second floating solar farm at Langthwaite Reservoir near Lancaster.
Some points from the Press Release.
- The floats are made locally.
- Godley is three times the size of Langthwaite.
- Godley can generate up to 3 GWh per year.
- It is thought that the panels help to stop the growth of algae in the water.
- United Utilities already has 45 MW of installed solar and intends to add 22 more sites in the next two years.
In some ways, this embracing of solar is a bit surprising, as the North West, is England’s wettest region.
Conclusion
If my excellent physics teacher in the 1960s had said that it will be commonplace by 2020 to generate electricity using solar panels floating on water, I would not have believed him!
UK’s Largest Solar Park Cleve Hill Granted Development Consent
The title of this post, is the same as that of this article on Solar Power Portal.
These are the two introductory paragraphs.
Cleve Hill Solar Park, set to be the largest in the UK, has been granted development consent by the energy secretary.
The colossal 350MW project will include 880,000 panels along with battery storage, and sit just one mile northeast of Faversham, in Kent, situated close to the village of Graveney.
Other points from the article.
- Cleeve Hill Solar Park is a £450million project.
- It is the first solar project to be considered a Nationally Significant Infrastructure Project.
- It is being developed as a joint venture between Hive Energy and Wirsol.
- It is due to be operational by 2022.
- To complete the project 700 MWh of energy storage will be added later.
The article also contains this quote from Solar Trade Associations chief executive Chris Hewett.
Solar has a significant role to play in boosting the economy in the wake of the coronavirus crisis. With the right policies we can expect to see an 8GW pipeline of solar projects unlocked and rapidly deployed, swiftly creating a wealth of skilled jobs and setting us on the path towards a green recovery.
8 GW of intermittent energy will need a lot of storage.
As Cleeve Hill’s developers are planning to provide 700 MWh of storage for 700 MW of solar panels, it would appear that 8 GW of solar panels could need up to 16 GWh of energy storage.
As our largest energy storage system is the pumped storage Electric Mountain in Snowdonia with a capacity of 9.1 GWh and most of the large solar developments are towards the South of England, the UK needs to develop a lot more energy storage, where the solar is generated and much of the energy is used.
I can see the following environmentally-friendly developments prospering.
- Highview Power‘s CRYOBattery, which uses liquid air to store energy. Systems have a small footprint and up to a GWh could be possible.
- Electrothermal energy storage like this system from Siemens.
- Using electrolysers from companies like ITM Power to convert excess energy into hydrogen for transport, steelmaking and injecting into the gas main.
- Zinc8‘s zinc-air battery could be the outsider, that comes from nowhere.
Developers could opt for conservative decision of lithium-ion batteries, but I don’t like the environmental profile and these batteries should be reserved for portable and mobile applications.
Floatovoltaics
One concept, I came across whilst writing was floatovoltaics.
The best article about the subject was this one on Renewable Energy World, which is entitled Running Out of Precious Land? Floating Solar PV Systems May Be a Solution.
A French company call Ciel et Terre International seem to be leading the development.
Their web site has this video.
Perhaps, some floatovoltaics, should be installed on the large reservoirs in the South of England.
- The Renewable Energy World article says that panels over water can be more efficient due to the cooling effect of the water.
- Would they cut evaporative losses by acting as sunshades?
- As the French are great pecheurs, I suspect that they have the answers if anglers should object.
This Google Map shows the reservoirs to the West of Heathrow.
Note.
- Wraysbury Reservoir has an area of two square kilometres.
- King George VI Reservoir has an area of one-and-a-half square kilometres.
- Using the size and capacity of Owl’s Hatch Solar Farm, it appears that around 65 MW of solar panels can be assembled in a square kilometre.
- All these reservoirs are Sites of Special Scientific Interest because of all the bird life.
- Heathrow is not an airport, that is immune to bird-strikes.
Could floatovoltaics be used to guide birds away from the flightpaths?
Incidentally, I remember a report from Tomorrow’s World, probably from the 1960s, about a porous concrete that had been invented.
- One of the uses would have been to fill reservoirs.
- The capacity of the reservoir would only have been marginally reduced, as the water would be in the voids in the concrete like water in a sponge.
- Soil would be placed at the surface and the land used for growing crops.
I wonder what happened to that idea from fifty years ago!
Hydrogen Power Plant Bid In Herne Bay Set For Green Light From Canterbury City Council
The title of this post, is the same as that of this article on Kent Online.
These are the introductory paragraphs.
Controversial plans to build a hydrogen fuel plant on a rundown plot of land look set to be given the green light – despite more than 160 objections from concerned residents.
Canterbury City Council was inundated with letters from locals – with one even worried about a Fukushima-style disaster – after a bid to construct the plant in Westbrook Lane, Herne Bay, was revealed in January.
The article said, that the project would create twenty jobs.
This Google Map shows the proposed site for the electrolyser.
Note.
- The Railway running East-West at the top of the map.
- The A2990 Thanet Way running East-West at the bottom of the map.
From a visualisation on the Kent Online article, it appears that the electrolyser will be built to the West of the Recycling Centre.
I suspect that given the closeness of the railway, it might even be possible to despatch hydrogen to users by specially-designed trains.
The electrolyser will need large quantities of electricity and I can’t see any wires around the site.
This Google Map shows the wider area around the site.
Note.
- The Recycling Centre indicated my a blue arrow, just to the right of top-centre of the map.
- The A2990 running East-West across the top of the map.
- The 18 MW Molehill Solar Farm between the old and new Thanet Ways, in the middle of the map.
- The 51.9 MW Owls Hatch Solar Farm, in the South East corner of the map.
- For full production, the electrolyser needs 23 MW!
These two solar farms, mean, that there must be a high-quality electricity connection in the area.
With all the offshore wind in Kent and these solar farms on the doorstep, the Herne Bay electrolyser, will not have much difficulty obtaining genuine renewable electricity.
Conclusion
As someone, who once worked, in a hydrogen factory, I would be happy to live near to the site.
Are Ryze Hydrogen planning to put a filling station for hydrogen vehicles on the A2990?
Hawaii’s Renewable Tender To Deliver Major Solar And Storage Push
The title of this post, is the same as that of this article on PVTech.
This is the introductory paragraph.
The largest renewable tender in Hawaii’s history has chosen its winners, contracting a solar and storage pipeline that exceeds anything the US state has ever seen.
The article gives a lot of information about the order and Hawaii’s energy.
- A fleet of 400 MW of solar panels and 3 GWh of energy storage will be installed, with some running in 2022.
- Another fleet of 260 MW of solar panels and 1 GWh of energy storage is in the pipeline, for delivery in 2021.
- The strike price appears to be 9.38 US dollar cents per KWh or $93.80 per MWh. We’re paying £92.50 per MWh for electricity at Hinckley Point C nuclear power station.
- Hawaii aims to be full-powered by renewable energy by 2045.
- Two fossil-fuel plants will shut by 2024.
From this document on the Hawaii State Energy Office, I have found that in 2018, these renewable energy sources contributed to the state’s electricity.
- Geothermal sources – 2.9%
- Wind – 4.9%
- Hydro – 0.9%
- Biomass – 2.8%
- Small-scale solar – 9.3%
- Utility-scale solar – 3.9%
These add up to 24.7%.
I’ll be interested to see, what the percentage will be in 2024!
Israel Should Be Funding Alternative Energy, Not Another Gas Pipeline
The title of the post, is the same as that of this article from The Jerusalem Post.
This is the introductory sub-title.
A pipeline only serves interests of the gas tycoons and not the taxpayers or the environmentally minded residents of the region.
The pipeline is proposed to run to Eilat in the South of Israel, which is an area, that gets enough sun for most of its electricity needs.
Some points from the article.
- Jordan will be 100 % daytime solar by 2030.
- Israel could be 100 % daytime solar by 2030.
- The Arava region of Israil will achieve this aim, by the end of this year.
The article gives an interesting insight into how you get electricity, when you have plenty of sun.
Highview Power And Railway Electrification
In Encore Joins Highview To Co-Develop Liquid Air Energy Storage System In Vermont, I gave brief notes about a proposed Highview Power CRYOBattery in Vermont.
- The system will supply 50 MW for eight hours.
- The total capacity will be 400 MWh.
Other articles have suggested, that the system could be built on the site of a demolished coal-fired power station, which still has a good connection to the electricity grid.
In other words, I believe that a CRYOBattery can be considered to be a small 50 MW power station.
- It could be charged by local excess renewable energy during the day.
- It could be charged by excess renewal energy from the electricity grid during the night, when there can be large amounts of wind energy, that needs a home.
- Intelligent control systems, would balance the output of the CRYOBattery to the needs of the electricity grid.
It would be used in very much the same way as gas-turbine power-stations are used in electricity grids all over the world.
The Braybrooke Feeder Station
The National Grid is providing a feeder station at Braybrooke to support the Midland Main Line electrification.
This page on the Harbough Rail Users site is entitled Electrification Substation Plan for Braybrooke.
It gives this description of the sub-station.
Electrification of part of the Midland Main Line has moved a tentative step closer with the plans being prepared by National Grid for a feeder substation at Braybrooke, just outside Market Harborough. The location is where a high-voltage National Grid power-line crosses over the railway and the plan is for a substation and associated equipment plus an access road from the A6. The substation is due to be completed by October 2020 and is intended to feed the power supply for the Corby line pending electrification of the main line through Market Harborough.
This Google Map shows the rough area, where it will be located.
Note.
- The A6 crossing the Midland Main Line.
- The solar farm in the South-facing field, which has a 3MW capacity, according to the Eckland Lodge Business Park web site.
- Various planning documents say the transformers on the substation will be 400/25 kV units.
- This means that the power-line in the area must be a 400 kV.
Unfortunately, I can’t pick out the line of 400 kV pylons marching across the countryside. But they are rather large.
The pictures show a group of 400 kV pylons near Barking.
- The Midland Main Line at Braybrooke certainly seems to be getting a solid supply of electricity.
- It was originally planned, that the electrification would go all the way, but it was cut back to Kettering and Corby a couple of years ago.
- But to power, the electrification to Corby, it is being extended all the way to Braybrooke, so that the electrification can act as a giant extension lead for the Corby Branch Line.
The page on the Harborough Rail Users Site says this.
The Braybrooke substation is still planned, however, and the DfT has advised that the bi-mode trains will be able to switch power mode at speed. They would therefore be able to continue running electrically north from Kettering as far as Braybrooke before ‘pan down’
It would appear, that the end of the electrification will be at Braybrooke, but the sub-station seems to have enough power to extend the electrification further North if that is ever planned.
I also think, that is rather an efficient and affordable solution, with very little modification required to the existing electricity network.
But not all electricity feeds to railway electrification have a convenient 400 kV line at a handy site for installing all the needed transformers and other electrical gubbins.
How Much Power Will Needed To Be Supplied At Braybrooke?
This can probably be dismissed as the roughest or rough calculations, but the answer shows the order of magnitude of the power involved.
Consider.
- Braybrooke must be sized for full electrification of the Midland Main Line.
- Braybrooke will have to power trains North of Bedford.
- If there is full electrification of the Midland Main Line, it will probably have to power trains as far North as East Midlands Parkway station, where there is a massive power station.
- Trains between Bedford and Market Harborough take thirty minutes.
- Trains between Bedford and Corby take around thirty minutes.
- Four trains per hour (tph) run between Bedford and Market Harborough in both directions.
- The system must be sized to handle two tph between Bedford and Corby in both directions.
- The power output of each Class 360 train, that will be used on the Corby route is 1,550 kW, so a twelve-car set will need 4.65 MW.
- I can’t find the power output of a Class 810 train, but an InterCity 125 with similar performance has 3.4 MW.
- A Class 88 bi-mode locomotive has a power output of 4 MW when using the electrification.
I estimate that Braybrooke could have to support at least a dozen trains at busy times, each of which could need 4 MW.
Until someone gives me the correct figure, I reckon that Braybrooke has a capacity to supply 50 MW for trains on the Midland Main Line.
A Highview Power system as proposed for Vermont, would have enough power, but would need a lot more storage or perhaps local wind or solar farms, to give it a regular charging.
Riding Sunbeams
Riding Sunbeams are a company, who use solar power to provide the electricity for railway electrification.
I’ll let their video explain what they do.
It’s a company with an idea, that ticks a lot of boxes, but would it be able to provide enough power for a busy electrified main line? And what happens on a series of rainy or just plain dull days?
Highview Power
Could a Highview Power energy storage system be used?
- To store electricity from local or grid electrical sources.
- To power the local electrification.
If required, it could be topped up by affordable overnight electricity, that is generated by wind power.
The Highview Power system could also be sized to support the local electricity grid and local solar and wind farms.
Conclusion
I think that Riding Sunbeams and Highview Power should be talking to each other.
