The Case For Pumped Hydro Storage
The Coire Glas Project
Note that Coire Glas is a pumped storage hydroelectric scheme being developed by SSE Renewables.
- It is rated at 1.5 GW.
- It can store 30 GWh of electricity.
- It is being built in the Highlands of Scotland above Loch Lochy.
- The estimated construction time will be five to six years.
- It should be operational for more than 50 years.
- There is more about the project on this page on the Coire Glas web site.
Exploratory works have started.
The Case For Pumped Hydro Storage
The title of this post, as the same as that of this page on the Coire Glas web site.
This is the sub-heading.
A study by independent researchers from Imperial College London found that investing in 4.5GW of pumped hydro storage, with 90GWh of storage could save up to £690m per year in energy system costs by 2050, as the UK transitions to a net-zero carbon emission system.
And this is the first paragraph.
The report focused on the benefits of new long-duration pumped hydro storage in Scotland, as the current most established long-duration energy storage technology. The benefit of long duration storage compared to short duration batteries is being able to continuously charge up the storage with excess renewables and also discharge power to the grid for several hours or days when wind and solar output is low.
So Coire Glas will provide 1.5GW/30GW, so where will we get the other 3 GW/60GW?
Loch Earba Pumped Hydro
In Gilkes Reveals 900MW Scottish Pumped Storage Plan, I introduced Loch Earba Pumped Hydro.
- It is rated at 900 MW
- It can store 33 GWh of electricity.
- It is being built in the Highlands of Scotland to the East of Fort William.
- The estimated construction time will be three to four years.
- It should be operational for more than 50 years.
- There is more about the project on the Earba Storage web site.
It would appear we could be edging towards the Imperial College target in lumps of about 1GW/30 GWh.
Other Schemes In Scotland
These are other proposed or planned schemes in Scotland.
Balliemeanoch Pumped Hydro
Balliemeanoch Pumped Hydro now has a web site.
The proposed Balliemeanoch pumped hydro scheme will have these characteristics.
- Output of the power station will be 1.5 GW
- Available storage could be 45 GWh.
This medium-sized station has a lot of storage.
Corrievarkie Pumped Hydro
Corrievarkie Pumped Hydro now has a web site.
The proposed Corrievarkie pumped hydro scheme will have these characteristics.
- Output of the power station will be 600 MW
- Available storage could be 14.5 GWh.
This medium-sized station has a moderate amount of storage.
Loch Kemp Pumped Hydro
I wrote about Loch Kemp Pumped Hydro in Loch Kemp Pumped Hydro, where I said this.
The proposed Loch Kemp pumped hydro scheme will have these characteristics.
- Loch Kemp will be the upper reservoir.
- Loch Ness will be the lower reservoir.
- The power station will be on the banks of Loch Ness.
- The power station will be designed to fit into the environment.
- Eight dams will be built to enlarge Loch Kemp.
- Trees will be planted.
- Output of the power station will be 300 MW
- Available storage could be 9 GWh.
The medium-sized station will have almost as much storage capacity as Electric Mountain, but that power station has an output of 1.8 GW.
Red John Pumped Hydro
I wrote about Red John Pumped Hydro in Red John Pumped Storage Hydro Project, where I said this.
I have also found a web site for the project, which is part of the ILI Group web site.
- The scheme has an output of 450 MW.
- The storage capacity is 2,800 MWh or 2.8 GWh.
- The scheme has planning consent.
- The project is budgeted to cost £550 million.
- The construction program indicates that the scheme will be completed by the end of 2025.
Not a large scheme, but every little helps.
Proposed Pumped Hydro In Scotland
I have listed these schemes.
- Balliemeanoch – 1.5GW/45 GWh
- Coire Glas – 1.5 GW/30 GWh
- Corrievarkie – 600 MW/14.5 GWh
- Loch Earba – 900 MW/33 GWh
- Loch Kemp – 300 MW/9 GWh
- Loch Na Cathrach/Red John – 450 MW/2.8 GWh
Note.
- The scheme’s name is linked to their web site.
- The two figures are output and storage capacity.
There is a total output of 5.25 GW and a total storage capacity of 134.3 GWh.
Conclusion
If all these schemes are built, Imperial’s targets of an output of 4.5 GW and a storage capacity of 90 GWh will be comfortably exceeded.
Gilkes Reveals 900MW Scottish Pumped Storage Plan
The title of this post, is the same as that of this article on renews.biz.
This is the sub-heading.
Earba project would be ‘largest in the UK’ in terms of energy stored
And this is the introductory paragraph.
Gilkes Energy has unveiled scoping plans for its 900MW Earba Pumped Storage Hydro Project in Scotland.
These are a few more details.
- It will have a capacity of 33 GWh.
- Loch a’ Bhealaich Leamhain is proposed to be the upper reservoir.
- Lochan na h-Earba is proposed to be the lower reservoir.
- There will be a three kilometre tunnel between the reservoirs.
- The 900 MW power station will be on the shore of Loch Earba.
- Construction is expected to take between 3 and 4 years.
This Google Map shows the location of the site.
And this Google Map shows the site.
Note.
- Lochan na h-Earba, which will be the lower reservoir is clearly marked, in the North-West corner of the map.
- Loch a’ Bhealaich Leamhain, which will be the upper reservoir is in the South-East corner of the map.
- Much of Loch a’ Bhealaich Leamhain appears to be frozen, with only a small triangular area of water visible.
- There doesn’t seem to be too many roads.
- There is a detailed map on the Earba Storage web site.
This looks like it could be extreme construction, at it’s most extreme.
Conclusion
With a power output of 900 MW and a storage capacity of 33 GWh, this pumped storage hydroelectric power station will have the largest storage capacity of any energy storage in the UK.
Swedish Battery-Electric Aircraft Selected By A Major Airline
The title of this post, is the same as that of this article on autoevolution.
This is the sub-heading.
You know that saying, “New year, new me”? In the case of this major airline, it’s more like “New decade, new me.” Air New Zealand wants to flaunt a brand-new regional fleet starting 2030. And it looks like that will include an all-electric model developed by the Sweden-based Heart Aerospace.
The article then gives a description of their plan called Mission Next Gen Aircraft to go zero-carbon on their short haul routes.
This paragraph describes the aircraft that will be used.
ATR will bring its upgraded aircraft concept, called the ATR EVO, designed to be 100% compatible with SAF (sustainable aviation fuel). Embraer will showcase the innovations of an entire new family of aircraft named Energia, based on various types of clean propulsion. Universal Hydrogen will retrofit the existing regional airliners with its efficient hydrogen solution. Last but not least, Heart Aerospace will focus on the niche segment of battery-electric aircraft.
It will be fascinating to see how all this works out.
We’re still waiting in the UK for an airline to announce the purchase of a zero-carbon aircraft.
Especially, as we have some routes, like those around Scottish islands, where there are many short routes, that have less than a dozen passengers on a flight.
Green Volt On Track To Power UK Oil & Gas Platforms By Mid-2020s
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Flotation Energy and Vårgrønn have submitted a Marine Licence application for the Green Volt floating offshore wind farm.
These two paragraphs outline the project.
This consent application could allow the project to start generating power in the mid-2020s, making it the most advanced oil and gas decarbonisation project in the UK, the developers said.
Flotation Energy and Vårgrønn are applying for a lease for Green Volt under the Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) round.
Green Volt wind farm already has a web site, which gives these details of the wind farm.
- It will be 50 miles off Peterhead.
- 300-500 MW
- Operational in 2027.
The offshoreWIND.biz article also says that the project has the potential to generate enough green power to electrify all major oil and gas platforms in the Outer Moray Firth area.
I can’t wait for the successful INTOG bids to be announced in April.
Engineers are creating exciting times.
Scotland And Brittany Discuss Partnership On Floating Wind Turbines
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A delegation of fifteen Scottish companies met in Rennes, France, with companies from the Brittany offshore wind and marine energy sector to discuss the development of partnerships around floating wind turbines.
I can see more partnerships like this.
Ofgem OKs Transmission Investments Needed For UK’s 2030 Offshore Wind Target
The title of this post, is the same as that, of this article on offshoreWIND.biz.
This is the sub-heading.
Ofgem has approved the strategic electricity transmission reinforcements required to deliver the UK Government’s 50 GW offshore wind by 2030 target, set out as part of the regulator’s Accelerated Strategic Transmission Investment (ASTI) framework.
A map then shows the principle new transmission reinforcements.
These include two 2 GW subsea HVDC links from Peterhead to England, both of which will be taken forward as joint ventures with National Grid Electricity Transmission (NGET), a 2 GW subsea HVDC link from Spittal in Caithness, connecting to Peterhead, as well as a 1.8 GW subsea HVDC link from Arnish on the Western Isles to the Beauly area near Inverness.
The approval also implies 400 kV onshore reinforcements, between Beauly, Blackhillock, New Deer and Peterhead; between Beauly, Loch Buidhe and Spittal; and between Kintore, Tealing and Westfield; and uprating the existing Beauly to Denny line to enable 400 kV operation on both circuits.
All cables seem to lead to Peterhead.
Scotland’s Renewable Energy Jackpot: Hydrogen Exports Alone Could Be worth £25 Billion A Year By 2045
The title of this post, is the same as that of this article on the Edinburgh News.
This is the sub-heading.
Scotland is a phenomenally energy rich country. For decades the largest oil-producing nation in the European Union, it is now set to trail-blaze as a leader in renewable energy.
The title and sub-heading say it all for Scotland.
But these words could equally well apply to Anglesey, Cornwall, Devon, East Anglia, Humberside, Liverpool and Morecambe Bays, the Severn Estuary and Pembrokeshire.
We also mustn’t forget the Dogger Bank!
Offshore Wind Developers Answer Scotland’s Call For Innovation, Oil And Gas Decarbonisation
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Crown Estate Scotland has received a total of 19 applications for its Innovation and Targeted Oil and Gas (INTOG) offshore wind leasing process.
INTOG
Note that there are two sections to INTOG.
This document on the Crown Estate Scotland web site, is entitled INTOG – Public Summary and it defines the two sections.
Innovation:
- To enable projects which support cost reduction in support of commercial deployment of offshore wind including alternative outputs such as Hydrogen.
- To further develop Scotland as a destination for innovation and technical development which will lead to risk reductions and supply chain opportunity.
Applications in this section should be no more than 100 MW in capacity.
Targeted Oil and Gas:
- To maximise the role of offshore wind to reduce emissions from oil and gas production.
- To achieve target installed capacity in a way that delivers best value for Scotland, creating supply chain opportunity in alignment with Just Transition principles.
A rough estimate is that powering rigs by using offshore wind would increase gas production by around ten percent.
The Applications
The article says this about the applications.
Of the 19 applications, ten are for the Innovation part, while nine have been submitted for the TOG element.
It is expected that up to 500 MW will be awarded to innovation projects and around 4 GW for projects looking to decarbonise oil and gas assets.
The article also lists the known bidders.
Conclusion
I believe that there is going to be some outstanding applications for leases under the INTOG scheme.
I have already written about Cerulean Winds ambitious proposal in Cerulean Winds Is A Different Type Of Wind Energy Company, which could result in 6 GW of wind turbines installed amongst the oil and gas fields to provide electricity and decarbonise the platforms and rigs.
DEME Returns To Scotland, Announces Offshore Wind Industry Firsts
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
DEME has won the contract to install foundations at the 882 MW Moray West wind farm offshore Scotland.
The industry firsts are described in these paragraphs.
In an industry breakthrough, the Moray West project will be the first time XXL monopiles will be installed in the winter period, and DEME will deploy its double-staged, motion-compensated pile gripper, the company said.
Moray West will also be the first time a vibro-hammer is being utilised for the XXL monopiles to overcome weaker soil layers.
Note.
- The water depth at Moray West wind farm is 35-54 metres, which necessitates the XXL monopiles.
- Working offshore in winter can be challenging.
- DEME’s gripper sounds just like what the engineers wanted.
This is just like with North sea oil and gas, where everything got bigger and more capable over time. But it did speed construction!
Global Port Services Wins Pre-Assembly Contract For Scottish Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
These are the first two paragraphs.
Global Port Services, owned by Global Energy Group alongside the Port of Nigg, has secured multiple contracts to support Seagreen Wind Energy Limited (SWEL) with site-enabling works for the pre-assembly construction of wind turbine components at its Port of Nigg facility.
The news comes as the final turbine foundations for the Seagreen offshore wind project arrive at Nigg to be prepared for installation 27 kilometres off the coast of Angus.
Note.
- Nigg is a village in the Highlands to the North of Inverness.
- The Port of Nigg has a busy Marine Fabrication Yard.
- There is a very interesting BBC documentary called Rigs of Nigg, which tells some of the stories of the port from the 1970s.
- As the article indicates, the yard is now very much involved in the wind power industry.
- SSE have invested in the yard.
This Google Map shows the port.
Note. all the yellow steel structures, which look like the fixed foundations for the Seagreen Wind Farm.
I am a bit surprised that foundations for Seagreen are being assembled a fair distance from Angus.
Is there not a fabrication yard on the Firth of Forth?
