Construction Under Way To Double Power Station Capacity At Centrica’s Brigg Energy Park
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Four ultra-efficient engines have arrived at Centrica’s former combined cycle gas power station at Brigg, with construction work underway on an expansion of the peaking plant at the Lincolnshire site.
These three paragraphs give more details about the project.
The business is installing the four engines inside the former turbine hall at the power station, which was decommissioned in 2020, helping to create nearly 100MW of fast response assets capable of meeting demand when renewable generation is low.
The expanded power plant will be hydrogen-ready, and form part of a trial due to start in late 2024 to blend hydrogen into the gas, ramping up from a three per cent blend to 20 per cent, with a long term vision to move towards 100 per cent hydrogen and to deploy similar technology across all peaking plants.
Work at Brigg is expected to last around nine months and the plant will be fully operational in early 2025.
These are my thoughts.
Hydrogen Blend Operation
The second paragraph indicates that Centrica will be using Brigg power station to research the use of hydrogen blends.
Hydrogen blends could offer a way an easy way to cut hydrogen emissions, so it is good, that Centrica are researching their use in gas-fired power stations.
Brigg As A Peaking Plant
This paragraph from the press release, explains what Centrica means by a peaking plant.
Peaking plants only generate electricity when there’s high or peak demand for electricity, or when generation from renewables is too low to meet demand. Once connected to the grid, the engines will have the capacity to power 20,000 homes for a full day when required, which will maintain stability and deliver reliable power across the grid.
The second paragraph also says this.
A long term vision to move towards 100 per cent hydrogen and to deploy similar technology across all peaking plants.
Does this mean that all peaking plants will move to hydrogen-fired generation?
Brigg Redevelopment
This paragraph from the press release, outlines Centrica’s plans for Brigg power station.
Centrica is redeveloping the Brigg energy park which, once complete, will be home to a 50MW battery, commercial-scale hydrogen production using HiiROC technology (in which Centrica has a five per cent stake), and 100MW of gas peaking plant.
Note.
- I would assume that the battery, will be able to provide 50 MW for at least two hours, so the battery electric storage system (BESS) will be at least a 50 MW/100 MWh unit.
- The HiiROC technology is being developed on the other side of the Humber in Hull.
- HiiROC technology captures the carbon in the gas as carbon black, which has uses in its own right, in agriculture and tyre and other manufacturing.
- Both a battery and a gas peaking plant, will be used at Brigg to match generation with demand.
I wouldn’t be surprised that to use both a battery and a gas peaking plant, is the most efficient way to balance the renewable energy.
Hydrogen Production
The HiiROC technology that will be used at Brigg can extract hydrogen from a variety of sources including biomethane, chemical plant off gas or natural gas.
The HiiROC technology can be scaled to fit the application.
I feel that the versatility of the HiiROC technology, may result in using some unusual feeds to produce hydrogen.
As an example of the deployment of a small HiiROC system , one at a sewage works could provide hydrogen for the utility company’s vehicles.
The main use of the hydrogen would be to provide a clean fuel for the gas-fired peaking plant.
I also wouldn’t be surprised to see the hydrogen, sold and distributed to the local area, from an energy park, like Brigg.
Conclusion
Increasingly, backup for renewables will use a wide range of zero-carbon technologies.
TetraSpar Demonstrator Floating Wind Turbine Hits 63 Pct Capacity Factor In Norway
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Stiesdal has revealed that its TetraSpar Demonstrator, located in Norway, has reached a capacity factor of 63 per cent.
These three paragraphs give a few more details.
Since its commissioning in late 2021, the TetraSpar Demonstrator has been operational at METCentre in Norway, delivering green energy, gathering data, validating numerical models, supporting research and development projects, and serving as a living laboratory for the development of floating wind technology, said Stiesdal in a recent social media post.
To date, the demonstrator has generated more than 37 GWh of renewable energy, according to the company. The 3.6 MW Siemens Gamesa direct-drive wind turbine and very high wind speeds at the METCentre site combined to yield a capacity factor of 54 per cent, said Stiesdal.
In the first two years of operation, the availability was recorded at 97 per cent and 98.3 per cent, respectively. For 2024, the availability has increased to 99.5 per cent with a capacity factor of almost 63 per cent, according to the company.
I have some further thoughts.
Tetra Offshore Foundations For Any Water Depth
The title of this section, is the same as that of this page on the Siesdal web site.
The page gives a lot of information and says that the TetraSpar can handle water depth of over a thousand metres.
Wind Farm Capacity Factor
The Wikipedia entry for capacity factor says this about the range of wind farm capacity factors.
Wind farms are variable, due to the natural variability of the wind. For a wind farm, the capacity factor is determined by the availability of wind, the swept area of the turbine and the size of the generator. Transmission line capacity and electricity demand also affect the capacity factor. Typical capacity factors of current wind farms are between 25 and 45%. In the United Kingdom during the five year period from 2011 to 2019 the annual capacity factor for wind was over 30%.
From that paragraph, 63 % seems to be extraordinarily good.
Conclusion
The TetraSpar appears to be a powerful concept.
An Incident In My Childhood
I must have been about five or six.
All I can remember, is that she found me very red all over, grabbed me and took me upstairs where she put me in a bath.
I don’t think, she called the doctor.
I now wonder, if the incident was when a low-pressure went over and it drained the water out of my body.
Last night, there was rain in the night, and I’ve woken up with a pain in my hip. I shall have a bath soon.
Strangely, none of my three boys seemed to suffer similar incidents. So perhaps, they don’t have my strange leaky skin?
