Mountain Marvel: How One Of Biggest Batteries In Europe Uses Thousands Of Gallons Of Water To Stop Blackouts
The title of this post, is the same as that of this article on The Guardian.
This is the sub-heading.
Much-loved’ Dinorwig hydroelectric energy storage site in Wales has a vital role to play in keeping the lights on
These are the first three paragraphs of the article.
Seconds after a catastrophic series of power outages struck across the UK in the summer of 2019, a phone rang in the control room of the Dinorwig hydropower plant in north Wales. It was Britain’s energy system operator requesting an immediate deluge of electricity to help prevent a wide-scale blackout crippling Britain’s power grids.
The response was swift, and in the end just under one million people were left without power for less than 45 minutes. While trains were stuck on lines for hours and hospitals had to revert to backup generators, that phone call prevented Britain’s worst blackout in a decade from being far more severe.
Almost six years later, the owners of Dinorwig, and its sister plant at Ffestiniog on the boundary of Eryri national park, formerly Snowdonia, are preparing to pump up to £1bn into a 10-year refurbishment of the hydropower plants that have quietly helped to keep the lights on for decades.
This is one of the best articles, I have read about pumped storage hydroelectricity.
It is very much a must read.
ENGIE And CDPQ To Invest Up To £1bn In UK Pumped Storage Hydro Assets
The title of this post, is the same as a news item from ENGIE.
These four bullet points act as sub-headings.
- Refurbishment programme to extend life of plants at Dinorwig and Ffestiniog will ensure the UK’s security of supply and support the transition to a low carbon energy future
- ENGIE owns 75% of the plants via First Hydro Company, a 75:25 joint venture with Canadian investment group CDPQ
- The two pumped storage hydro plants are the UK’s leading provider of power storage and flexibility, with 2.1GW of installed capacity
- They represent 5% of the UK’s total installed power generation capacity and 74% of the UK’s pumped storage hydro capacity
These three paragraphs give more details.
The preparation of a 10-year project of refurbishment at *ENGIE’s Dinorwig pumped storage station has begun, following an 8-year refurbishment at Ffestiniog, enabling the delivery of clean energy whenever needed.
These flexible generation assets, based in North Wales, are essential to the UK Government’s accelerated target of achieving a net zero carbon power grid by 2030. Together they help keep the national electricity system balanced, offering instant system flexibility at short notice. The plants are reaching end of life and replanting will ensure clean energy can continue to flow into the next few decades.
Re-planting could see the complete refurbishment of up to all six generating units at Dinorwig – a final investment decision is still to be made on the number of units to replace – while the re-planting at Ffestiniog will be completed at the end of 2025. The program also involves the replacement of main inlet valves – with full drain down of the stations – and detailed inspections of the water shafts.
It also looks like the complete refurbishment at Dinorwig will take ten years, as it seems they want to keep as much of the capacity available as possible.
When the replanting is complete, the two power plants will be good for twenty-five years.
Hopefully, by the time Dinorwig has been replanted, some of the next generation of pumped storage hydroelectric power stations are nearing completion.
The news item says this about Dinorwig.
Dinorwig, the largest and fastest-acting pumped storage station in Europe, followed in 1984 and was regarded as one of the world’s most imaginative engineering and environmental projects.
Dinorwig must be good, if a French company uses those words about British engineering of the 1980s.
Aurizon Secures Funding To Develop Next-Generation Freight Trains Using Renewable Energy
The title of this post, is the same as that of this press release from Aurizon.
These five paragraphs outline the project.
Australia’s largest rail freight company Aurizon, today received a major boost to its program to develop the next generation of Australian freight trains, aiming to replace diesel fuel with renewable energy sources on its locomotive fleet.
Aurizon has secured a $9.4 million grant from the Australian Renewable Energy Agency (ARENA) to develop, test and trial a battery electric tender (BET) to be used in conjunction with a modified locomotive. (refer graphic below).
The tender – essentially a big battery-pack on wheels – will couple with the modified locomotive to operate as a hybrid unit using both diesel and battery-electric power sources. The tender’s battery will also harness re-generative energy captured as the train travels down grades and brakes as part of normal operation.
The ARENA grant represents half of the required funding for the ‘Battery Powered Tender for Heavy Haul Fleet Decarbonisation’ project, with the balance of the investment to be funded by Aurizon. The battery-electric tender and modified locomotive project will be built by Aurizon and technology project partner, Alta Battery Technology (Alta) at a facility in Australia, with design and technology inputs from Alta.
Aurizon appreciates the Federal Government making funding available to support the development of a range of new zero emissions technologies in the transport sector, including technologies that can be developed for application in rail-based freight supply chains that are integral to Australia’s export and domestic industries that rely on transport services.
At a first glance it appears to be suited to Aurizon and its long routes with heavy freight trains across Australia.
These are some more specific thoughts.
Alstom Have Built A Train With a Hydrogen Tender
In From 2025, Nestlé Waters France Will Use The First Hydrogen-Powered Freight Train Through An Innovative Solution Developed by Alstom and ENGIE, I describe a train powered by an electric locomotive with an attached hydrogen power unit.
The Future Of The Class 68 Locomotives
Could these be given a reduced-carbon second life, by developing a specialised tender?
I wrote about this in The Future Of The Class 68 Locomotives.
I suspect Stadler, who seem to be excellent innovators will be watching.
There Seems To Be A Lot Going On In Australia
I have written several posts about decarbonisation of freight trains in Australia.
- BHP To Trial Battery Locos On Pilbara Iron Ore Network
- Battery-Electric Power Rides The Rails
- Wabtec And Roy Hill Unveil The First FLXdrive Battery Locomotive
- Fortescue Unveils World-First Electric Train Using Gravity To Recharge
- BHP Joins The Party On Electric Rail
- Rio Tinto Orders Wabtec FLXdrive Battery Locomotives To Reduce Emissions
The big mining companies certainly seem keen to decarbonise.
World’s First Semi-Submersible Floating Offshore Wind Farm Smashes Predictions
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
WindFloat Atlantic, the world’s first semi-submersible floating offshore wind farm, has completed its third year in operation, closing in 2023 with an electricity production of 80 GWh.
These four paragraphs outline the performance of the wind farm.
Connected to the grid by the end of 2019 and fully commissioned in 2020, the floating offshore wind farm was developed by the Windplus consortium formed by Ocean Winds, a 50:50 joint venture between EDPR and ENGIE, Repsol, and Principle Power.
The pioneer wind farm consists of three platforms, each supporting one 8.4-MW Vestas turbine, which are anchored with chains to the seabed and connected to the onshore substation in the Portuguese municipality of Viana do Castelo through a 20-kilometre cable.
According to the project’s owners and operators, the 25 MW WindFloat Atlantic also closed in 2023 breaking more records with Storm Ciaran posing challenges with waves reaching a maximum height of 20 metres and wind gusts up to 139 kilometres per hour.
These conditions far surpassed the project’s previous records, demonstrating the readiness and robustness of the floating technology, even in extreme offshore conditions.
It would appear that this and the previous post; France’s First And Only Operational Floating Wind Turbine Gets Lifetime Extension, are not only indicating that floating wind power works, but that it works well in all types of conditions.
Amazon Books Over Half Of Moray West Offshore Wind Capacity To Power UK Operations
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Amazon has signed a corporate power purchase agreement (CPPA) for a total of 473 MW of Moray West offshore wind farm’s generation capacity to help power its operations when the project becomes operational later this year.
These are the first two paragraphs.
The technology giant signed the CPPA with ENGIE, which owns the Moray West project through Ocean Winds, the 50-50 joint venture between ENGIE and EDP Renewables.
The 473 MW Amazon secured through the agreement is enough to power the equivalent of more than 650,000 UK homes annually and is more than half of the total installed capacity of the 882 MW Moray West offshore wind farm.
Note.
- In Google Buys Scottish Offshore Wind Power, I talked about how Google had signed a Corporate Power Purchase Agreement to buy 100 MW from the Moray West offshore wind farm.
- This would mean that there’s still 305 MW of capacity to allocate.
- I would assume you wouldn’t sell hundred percent of capacity to give yourself leeway.
But what do you do, if your wind farm isn’t producing the 573 MW you need to satisfy the CPPAs you’ve sold? I suspect you have to buy it on the market.
If And When Do Amazon Think About Batteries?
My twenty-five-year-old self could have developed methods to calculate the answer to that question, as it would have been a simple calculation for the analogue computer, that I was using at the time; a PACE-231-R.
They really were magnificent machines.
Moray West First UK Round 4 Offshore Wind Project To Reach Financial Close
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Moray West Offshore Wind Farm, owned by Ocean Winds and minority shareholder Ignitis Group, has secured GBP 2 billion of non-recourse project finance and reached financial close, the developers announced on 21 April and said this was the first project from the UK’s Contract for Difference (CfD) Allocation Round 4 to reach this milestone.
This is the first paragraph.
The construction work for the wind farm has already started, with this phase of the project set to create 1,000 direct jobs in the UK. With financial close in place, the project will now move to secure the remaining elements of supply chain activity in preparation for offshore installation works later this year which will be fully completed by 2025, when the 882 MW Moray West is scheduled to be fully operational.
That sounds good for Scotland and electricity users in the UK.
But this paragraph is probably the most important.
According to its developers, the 882 MW offshore wind farm is the first in the UK to rely in majority on corporate power purchase agreements (CPPAs) for the commercialisation of its output. CPPAs were signed with long-term strategic partners, for more than 50 per cent of the project’s output, enabling the rapid progress of the project. The vital CPPAs were originated in partnership with ENGIE and represent the largest contracts of their kind implemented in the UK market to date, Ocean Winds said in a press release.
There’s not much point in making something that nobody wants to buy at the price you need for a profitable sale.
But with all those CPPAs, one of which is with Google, Moray West wind farm appears to be on his way.
Google Buys Scottish Offshore Wind Power
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading and the first paragraph.
ENGIE and Google have entered into a 12-year, 100 MW corporate power purchase agreement (CPPA) supporting the Moray West offshore wind development in Scotland.
ENGIE will provide Google with more than 5 TWh of green power from the Moray West project, a nearly 900 MW offshore wind farm set to begin generating power from 2025.
Increasingly, it seems that large energy users are committing themselves to long-term energy deals.
One of Google’s senior people is quoted as saying.
People across the UK and Europe are increasingly worried about climate change and energy security. We share that concern and believe technology is an important part of the solution – both by reducing our own emissions, and by helping others to reduce their own.
I have a few thoughts.
How Much Of Moray West’s Output Is 5 TWh?
Consider.
- Moray West has an maximum output of 882 MW.
- This converts to 7.73 TWh.
If Google are buying all the electricity produced by the wind farm, that would mean that the capacity factor is around 64.7 %, which is quite reasonable, if a bit high for a fixed foundation wind farm.
If we are, it does surely reflect a desire for stability and security in a fast-changing world.
Are We Seeing More Corporate Power Purchase Agreements (CPPAs)?
From 2025, Nestlé Waters France Will Use The First Hydrogen-Powered Freight Train Through An Innovative Solution Developed by Alstom and ENGIE
The title of this post, is the same as that of this press release from Alstom.
These are the main points of the press release.
-
Nestlé Waters will be the first company in Europe to benefit from the hydrogen fuel cell solution developed by Alstom and ENGIE, for rail freight.
-
The purpose is to operate the first hydrogen-powered freight train from the Vosges plant, thanks to a hydrogen generator wagon system developed by Alstom and supplied with renewable hydrogen by ENGIE, from 2025.
-
Ultimately, this project should enable Nestlé Waters to reduce emissions by 10,000 tons of CO2 equivalent per year.
-
This new collaboration is in line with the actions Nestlé Waters has been carried out for several years to decarbonize its supply chain.
In this Alstom visualisation that accompanies the press release, an Alstom Prima locomotive can be seen pulling a tender full of hydrogen, that generates electricity.
It would appear to be a very simple concept.
- The electric locomotive uses electrification where it is available.
- On lines without electrification, hydrogen is used to generate electricity.
- The locomotive and the tender are connected by a cable.
- I suspect for longer distances, larger generators with a larger hydrogen capacity can be developed.
- It would appear that typical SNCF Prima locomotives have at least 4 MW of power, so the generator must be at least this size.
I could see this concept being used with a 4 MW Class 90 electric locomotive.
