Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch
The title of this post, is the same as that as this news item from Centrica Business Systems.
This is the sub-heading.
Centrica Business Solutions has started work on a 20MW hydrogen-ready gas-fired peaking plant in Worcestershire, as it continues to expand its portfolio of energy assets.
These three paragraphs outline the project.
Centrica has purchased a previously decommissioned power plant in Redditch, and is set to install eight UK assembled containerised engines to burn natural gas.
Expected to be fully operational later this year, the peaking power plant will run only when there is high or peak demand for electricity, or when generation from renewables is low. The Redditch project will have the capacity to power the equivalent of 2,000 homes for a full day when required, helping to maintain stability and reliability on the grid.
The engines will also be capable of burning a blend of natural gas and hydrogen, futureproofing the site and helping the UK transition towards a decarbonised energy system.
- The original power station had Rolls-Royce generators.
- Cummins and Rolls-Royce mtu and possibly other companies can probably supply the dual fuel generators.
- Cummins have received UK Government funding to develop hydrogen-powered internal combustion engines.
- This press release from Cummins, which is entitled Dawn Of A New Chapter From Darlington, gives more details on Cummins’ plans for the Darlington factory and hydrogen.
Given that Cummins manufactured sixty-six thousand engines in Darlington in 2021 and it is stated that these containerised engines will be assembled in the UK, I feel, that these engines may be from Cummins.
Centrica’s Plans
This paragraph in the Centrica Business Systems news item, outlines their plans.
The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.
As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.
Brigg Power Station
The Wikipedia entry for Brigg Power station gives these details of the station.
- The station was built in 1993.
- It is a combined cycle gas turbine power station.
- The primary fuel is natural gas, but it can also run on diesel.
- It has a nameplate capacity of 240 MW.
Brigg power station is also to be used as a test site for hydrogen firing.
This news item from Centrica is entitled Centrica And HiiROC To Inject Hydrogen At Brigg Gas-Fired Power Station In UK First Project.
These paragraphs from the news item explains the process.
The 49MW gas fired plant at Brigg is designed to meet demand during peak times or when generation from renewables is low, typically operating for less than three hours a day. Mixing hydrogen in with natural gas reduces the overall carbon intensity.
It’s anticipated that during the trial, getting underway in Q3 2023, no more than three per cent of the gas mix could be hydrogen, increasing to 20% incrementally after the project. Longer term, the vision is to move towards 100% hydrogen and to deploy similar technology across all gas-fired peaking plant.
HiiROC’s proprietary technology converts biomethane, flare gas or natural gas into clean hydrogen and carbon black, through an innovative Thermal Plasma Electrolysis process. This results in a low carbon, or potentially negative carbon, ‘emerald hydrogen’.
Because the byproduct comes in the form of a valuable, solid, pure carbon it can be easily captured and used in applications ranging from tyres, rubbers and toners, and in new use cases like building materials and even as a soil enhancer.
It looks to me, that HiiROC are using an updated version of a process called pyrolysis, which is fully and well-described in this Wikipedia entry. This is the first paragraph.
The pyrolysis (or devolatilization) process is the thermal decomposition of materials at elevated temperatures, often in an inert atmosphere. It involves a change of chemical composition. The word is coined from the Greek-derived elements pyro “fire”, “heat”, “fever” and lysis “separating”.
Pyrolysis is more common than you think and is even used in cooking to do things like caramelise onions. This is a video of a chef giving a demonstration of caramelising onions.
On an industrial scale, pyrolysis is used to make coke and charcoal.
I came across pyrolysis in my first job after graduating, when I worked at ICI Runcorn.
ICI were trying to make acetylene in a process plant they had bought from BASF. Ethylene was burned in an atmosphere, that didn’t have much oxygen and then quenched in naphtha. This should have produced acetylene , but all it produced was tonnes of black soot, that it spread all over Runcorn.
I shared an office with a guy, who was using a purpose-built instrument to measure acetylene in the off-gas from the burners.
When he discovered that the gas could be in explosive limits, ICI shut the plant down. The Germans didn’t believe this and said, that anyway it was impossible to do the measurement.
ICI gave up on the process and demolished their plant, but sadly the German plant blew up.
It does look like HiiROC have tamed the process to be able to put hydrocarbons in one end and get hydrogen and carbon black out the other.
I wonder how many old and possibly dangerous chemical processes can be reimagined using modern technology.
It certainly appears that Centrica are not holding back on innovation.
Conclusion
I’ve never run a large electricity network. Not even a simulated one.
But I’m fairly sure that having a large number of assets of different sizes, that can be optimised to the load and the fuel available, creates a more reliable and efficient network.
Heavy energy users may even have their own small efficient power station, that is powered by gases piped from the local landfill.
Angus Peter Campbell: I’m In Two Minds About The Renewable Energy Revolution
The title of the post, is the same as that of this article in the Aberdeen Press and Journal.
This is the sub-heading.
The debate (argument) between development and environmentalism is as old as the hills.
In the article, Campbell puts all sides of the arguments over the Coire Glas pumped storage hydro-electric scheme, and the article is very much a must read.
I feel that this 1500 MW/30 GWh scheme should be built, as like Hinckley Point C and Sizewell C, it takes a large bite out of the new energy storage capacity that is needed.
But if we do build this large project, we should think very hard about how we do it.
These are a few thoughts.
Low Carbon, Disturbance And Noise During Construction
High Speed Two are doing this and I wrote about it in HS2 Smashes Carbon Target.
I do subject though, that increasingly large construction projects can go this way.
Electric Trucks, Cranes And Other Equipment
High Speed Two and big mining companies are increasingly using electric mining trucks, cranes and other equipment.
As this sort of equipment, also provides a better environment for workers, I suspect we’ll see more electric equipment.
Hydrogen Trucks And Construction Equipment
Hydrogen could play a big part and rightly so.
It is ideal for heavier equipment and one of its biggest advocates and developers is JCB.
I wouldn’t be surprised to see a decision about an onsite electrolyser being made soon.
Low Carbon Concrete
There are various methods of making low- and zero-carbon concrete, some of which incorporate carbon dioxide into the material.
Use Of Loch Lochy And The Caledonian Canal
I wouldn’t be surprised if just as the Thames in London was used in the construction of Crossrail and the Northern Line extension, Loch Lochy and The Caledonian Canal will be used to take out construction spoil.
There’s certainly a lot of ways to be innovative in the movement of men and materials.
Conclusion
The construction of Coire Glas will make an epic documentary.
SSE Renewables Unveils Plans For Wind Farm Offshore Ireland’s Atlantic Coast
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
SSE Renewables is seeking an investigative foreshore licence to facilitate survey work for a possible new offshore wind farm in the Atlantic Ocean off the coast of Tarbert, Co. Kerry, Ireland.
This Google Map shows the approximate location of Tarbert.
These two paragraphs outline the project.
SSE Renewables has recently submitted an application for an investigative foreshore licence to Ireland’s Department of Housing, Local Government and Heritage and is seeking approval for investigative surveys of the seabed for an offshore wind project which could generate up to 1 GW of energy.
These geophysical, geotechnical, and environmental surveys are required to inform the renewable energy developer’s understanding of the prevailing environmental and met-ocean conditions at the foreshore investigative array area, which is a minimum of 13 kilometres offshore.
This is SSE Renewables’ first licence application for an offshore wind project off the west coast of Ireland.
In SSE Thermal Secures 10-year Contracts For Two New Low-Carbon Power Stations In Ireland, I talked about two biomass power stations at Tarbert in Co. Kerry and Platin in Co. Meath.
It looks like the Tarbert wind farm and power station will work as a team and back each other up.
We Mustn’t Forget Platin!
This Google Map shows Dublin and its position relative to the North Wales coast.
Note.
- Platin is marked by the red arrows to the North of Dublin.
- Platin also appears to be the head office and a manufacturing site of Irish Cement, who probably are a large user of energy.
- The sea between Blackpool, Liverpool, Anglesey and the Isle of Man is full of wind turbines.
These wind farms are located in this area of UK waters.
- Barrow – 30 MW
- Burbo Bank – 90 MW
- Burbo Bank Extension – 258 MW
- Gwynt y Môr – 576 MW
- Ormonde – 150 MW
- Rhyl Flats – 90 MW
- Walney – 367 MW
- Walney Extension – 650 MW
- West Of Duddon Sands – 389 MW
- Mona – 1500 MW – Being Planned
- Morecambe – 480 MW – Being Planned
- Morgan – 1500 MW – Being Planned
- Awel y Môr – 500 MW – Being Planned
Note.
- 2600 MW has been commissioned.
- 3980 MW is being planned.
I would not be surprised to see SSE or one of their friends, build a GW-scale wind farm between Anglesey, Dublin and Dundalk.
Is Ireland apparently lagging behind the UK, because the waters near the Irish coast are deeper and would need still-developing floating wind technology?
Conclusion
It looks like the Irish government and SSE are planning a low-carbon electricity system for Ireland.
Highview Power And Ørsted Collaborate To Unlock Greater Value From The Next Generation Of Wind Farms
The title of this post, is the same as that of this press release from Ørsted.
This is the sub-heading.
Highview Power and Ørsted have signed a Memorandum of Understanding aiming to prove the feasibility and economic value of co-locating long duration energy storage with offshore wind.
This first paragraph indicates how the two companies will work together.
The two companies will carry out detailed technical analysis and an economic assessment during 2023 that will investigate how combining Ørsted’s wind technology with Highview Power’s liquid air energy storage can deliver a stronger investment case for future offshore wind projects by reducing wind curtailment, increasing productivity, and helping the move to a more flexible, resilient zero carbon grid.
This all good stuff and as a Control Engineer, I know, there is a very good chance, it will bring forward worthwhile benefits.
Are These Turbines An Alternative To Solar Panels?
I took this picture yesterday of the Ventum Dynamics turbine on Skegness Pier.
On the Ventum Dynamics web site, there are several pictures of buildings with flat roofs, that have several turbines on each.
I have some thoughts.
Connecting The Turbines
The Skegness turbine has been installed to light up the pier, but it doesn’t seem to have masses of cabling!
So can one of these turbines or a whole fleet of them be connected up by a qualified electrician, who is familiar with connecting up solar panels?
It would certainly, be a positive feature if they could, as these turbines could be another string to the bow of a solar power company.
I would design them to be electrically interchangeable with solar panels, so that roofs could be covered by a mixture of both solar and wind power.
Will We See more Hybrid Systems?
Cleve Hill Solar Park in Kent is being built as a solar park with a battery close to the London Array offshore wind farm.
I can see batteries and Ventum’s turbines being added to solar farms.
Conclusion
Ventum’s turbines are both an alternative and a partner to solar panels.
Windeed’s Floater Solution Gets Bureau Veritas Nod
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Bureau Veritas has granted Approval in Principle (AiP) to Sweden-based Windeed for its low-weight and low-acceleration floater solution for offshore wind turbines.
These three paragraphs fill in more details.
The AiP is a significant milestone in the development of Windeed’s technology, which could offer competitive prices and lower levelised cost of energy (LCOE) compared to other solutions on the market due to its industrialised manufacturing process, the developer said.
Bureau Veritas provided testing and assessment to ensure the solution is safe, reliable, and ready for deployment.
The approval in principle is a testament to the quality and innovation of the company’s technology.
I have been waiting some months for a new more efficient float for offshore wind turbines and then Gazelle Power Systems and Windeed turn up with designs on the same day.
Pictures of Gazelle’s design are available on their web site, but Windeed’s web site is text only, although it does say this.
Our purpose is to provide superior technology and industrialization of floating offshore wind power, lowering costs and environmental impact, to meet the need of more and clean energy.
I wouldn’t be surprised to see other designs!
SSE Thermal Secures 10-year Contracts For Two New Low-Carbon Power Stations In Ireland
The title of this post, is the same as that of this press release from SSE.
These first two paragraphs outline the two projects.
SSE Thermal, as part of SSE plc, has provisionally secured 10-year capacity agreements for its two proposed new-build power stations in Ireland which would run on sustainable biofuel.
The proposed low-carbon units at Tarbert in Co. Kerry and Platin in Co. Meath received the contracts in the T-4 Capacity Auction to commence in the 2026/27 delivery year.
Note.
- Both plants would help to protect security of supply and provide flexible backup to Ireland’s growing renewables sector.
- This Wikipedia entry is entitled Renewable Entry In Ireland and states that by the end of 2021, Ireland had 4.4 GW of onshore wind, with the intention of adding 5 GW of offshore wind, by 2030.
- The proposed units will initially run on Hydrotreated Vegetable Oil (or HVO), which is produced by processing waste oils to create a fossil-free alternative to diesel in accordance with EU sustainability standards.
- It looks like the two new-build HVO-powered station will back up the renewables.
- It is intended that the two new power stations will be in operation in 2026.
The two new power stations will be convertible to hydrogen in the future.
As at Keadby in Lincolnshire, which I wrote about in SSE Thermal Charts Path To Green Hydrogen Future With First-Of-A-Kind Project. it looks like SSE have developed a comprehensive plan to keep the electricity at full power, even when the wind isn’t blowing.
Conclusion
SSE Thermal are showing that in addition to gas, nuclear and pumped storage hydroelectric, renewables can also be backed up by biomass.
Irish Floating Wind Tech Developer Unveils Pilot Project In Portugal
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dublin-based floating wind technology company Gazelle Wind Power (Gazelle) has partnered with the Portuguese renewable energy developer WAM Horizon to accelerate the development of a pilot project in Aguçadoura, Portugal, which will use Gazelle’s floating wind platform.
And this is the first paragraph.
Within the partnership, WAM will provide Gazelle with strategic advisory to implement the pilot project.
There is also a picture, which does not look like any other float for a wind turbine, that I’ve seen.
Gazelle Wind Power’s home page, has a series of pictures and an explanation of how it works.
The web site claims the technology is Light, Agile and Fast and gives a few details in this paragraph.
Introducing Gazelle’s hybrid attenuated mooring platform, an evolutionary step-change in the design of floating platforms. Lighter, smaller and more agile than current designs, the Gazelle delivers unmatched stability and capacity. Moreover, our design benefits from modularisation, time-tested manufacturing processes, and can easily be assembled at port facilities worldwide.
From my experience of modelling floating structures in the 1970s, I believe that there a lot more permutations and combinations of components, that will work as floats for wind turbines.
Gazelle Wind Power’s design, is one of the first of a new generation of designs.
If anybody comes up with an unusual design and needs someone to criticise or model its floating behaviour, I’d be happy to help.
Skegness Pier With Wind Turbines
These pictures were taken today from Skegness pier.
Note.
- The wind turbines on the horizon in the first seven pictures are the 270 MW of the Lincs wind farm and the 194 MW Lynn and Inner Dowsing wind farm.
- All wind turbines are just a few miles offshore.
- All turbine in these wind farms has a capacity of 3.6 MW.
The small cylindrical object actually on the pier in the last five pictures is also a wind turbine.
It is a vertical-axis turbine from Ventum Dynamics of Norway.
In Skegness Wind Turbine Trial To Light Up Pier In UK First, I wondered if it is noisy! It is not!
Green Hydrogen to Flow From Denmark To Germany From 2028
The title of this post, is the same as that of this article on Hydrogen Central.
These are the two introductory paragraphs.
Green hydrogen to flow from Denmark to Germany from 2028.
The climate minister, Lars Aagaard, and the German economy and climate minister, Vice Chancellor Robert Habeck, signed an agreement in Copenhagen to build a land-based hydrogen pipeline from Denmark to Germany, which will commence operations in 2028.
The article also says this about the hydrogen infrastructure to Germany.
An underground hydrogen pipeline from western Jutland will probably be used to transfer the hydrogen to northern Germany. The capacity of the new pipeline was not confirmed.
I can see the UK having the means to export hydrogen to Europe.
