Brits Are Future Proofing Their Homes, Increasingly Valuing Sustainable Elements
The title of this post, is the same as that of this news item from Centrica.
These are the first two paragraphs.
It may still be true that for many, their home is their ‘castle’ but if so, it better be a well-insulated castle, as new research shows that Brits increasingly value energy efficient and environmentally friendly houses.
A survey from Hive revealed that the top selling points on a dream home for modern Brits are related to sustainability, with solar panels (68 percent) and good roof insulation (67 percent) valued more than design features such as natural lighting (53 percent), wooden flooring (22 per cent) and reclaimed woodwork (21 percent). Smart home technology such as a smart heating system (62 percent), a smart energy meter (48 percent) and an EV charger on the driveway (39 percent) were also top considerations.
As I fitted solar panels and good roof insulation to my house, their research could fit me.
I haven’t fitted an EB charger as I don’t drive.
Centrica Bolsters UK’s Energy Security By Doubling Rough Storage Capacity
The title of this post, is the same as that of this news item from Centrica.
These are the first three paragraphs.
Following further engineering work and investment, Centrica has announced increased gas storage capacity at Rough, the UK’s largest gas storage facility.
The facility, which is 18 miles off the coast of East Yorkshire, stopped storing gas in 2017 but was re-opened for gas storage in October 2022. Rough now provides half of the UK’s total gas storage.
At the time of reopening Rough for gas storage it was able to store approximately 30 billion cubic feet (bcf) of gas for UK homes and businesses. Further investment in the facility means Rough will now be able to store up to 54 bcf of gas, boosting the UK’s energy resilience for the coming winter – this would provide the equivalent volume of gas to heat 2.4 million homes over winter.
This work and investment has increased the storage capacity by a massive eighty percent.
The news item finishes with this quote from Centrica Group Chief Executive, Chris O’Shea.
We stand ready to invest £2 billion to repurpose the Rough field into the world’s biggest methane and hydrogen storage facility, bolstering the UK’s energy security, delivering a net zero electricity system by 2035, creating 5,000 skilled jobs and decarbonising the UK’s industrial clusters by 2040. But to do this we need the right regulatory support framework. This world class North Sea asset has the potential to help the UK economy return to a position of being a net exporter of energy once again.
As East Yorkshire also boasts the Aldbrough Gas Storage in the salt formations under Hull, the area will have plenty of gas to keep them warm in the winter.
How Britain’s Biggest Natural Battery Can Help Deliver Net Zero
The title of this post, is the same as that of this article in the New Statesman.
This is the sub-heading.
SSE wants to double the nation’s flexible electricity storage capacity.
These two paragraphs introduce the article.
After previous delays and false starts, governments and businesses across the world are pushing towards the common goal of net zero. The energy sector is arguably the area with the biggest responsibility to work towards this target, and there is no time for complacency.
Ensuring clean, renewable energy sources such as hydrogen, wind and solar power become a larger part of the grid will be critical for the sector in its push towards net zero. A key facet of the clean energy drive will be having sufficient storage for each renewable power source kept in reserve, to be used as and when required as a crucial back-up mechanism. In last spring’s energy security review the government outlined its commitment to support long duration storage projects.
It is certainly very comprehensive and a must read.
This sentence illustrates the financial problem with pumped storage.
SSE is calling on the UK government to help it commit to building the Coire Glas storage facility by providing one simple policy decision that will send a clear signal as to how government intends to support the deployment of long duration electricity storage. The project doesn’t need subsidising, SSE states, but it would benefit from revenue stabilisation, and clarity on such support sooner rather than later.
Hopefully, this article will help get the required support.
Coire Glas
Coire Glas will have an output of 1500 MW and a storage capability of 30 GWh.
There is more information at the Coire Glas web site.
The project could be up and running by the early 2030s.
Loch Sloy Pumped Storage
The article also mentions the Loch Sloy Pumped Storage scheme, that has been recently announced by SSE.
I wrote about this 25 GWh scheme in SSE Unveils Redevelopment Plans For Sloy Hydro-Electric Power Station.
SSE haven’t announced much more about this scheme and it is not mentioned on the Sloy/Awe web site.
Irish Offshore Wind Developer Teams Up With Norwegian Seaweed Farming Company
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ireland-headquartered Simply Blue Group and Norwegian seaweed farming company, Arctic Seaweed, have signed a memorandum of understanding (MoU) under which they will jointly explore solutions for co-locating seaweed farms and offshore wind farms.
Simply Blue Group has an informative web site.
This news item on the Simply Blue Group web site gives full details of the project.
Arctic Seaweed has a web site, with this philosophy on the home page.
At Arctic Seaweed, our philosophy revolves around leveraging disruptive technology to revolutionize the seaweed cultivation industry.
We believe that by embracing scale and cutting-edge innovations, we can drive a transformative shift in the market.
Through our commitment to pushing boundaries and fostering collaborations, we are paving the way for a future where disruptive technology creates unprecedented opportunities in seaweed cultivation.
Both companies seem to be very professional.
Scotland’s Largest Offshore Wind Farm Stands Complete
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The final turbine has been installed at Scotland’s largest offshore wind farm, Seagreen, off the coast of Angus.
These two paragraphs describe the wind farm.
Once fully operational, the Seagreen project, owned by TotalEnergies and SSE Renewables, will reach almost 1.6 GW.
76 of the 114 Vestas V164-10.0 MW turbines are now energised at the site, which is located 27 kilometres from the Angus coast.
The article also says, that the units are now producing more than two-thirds of Seagreen’s full capacity power to the grid.
It seems like the Seagreen wind farm has got off to a good start.
30 MW Offshore Wind Turbines Being Considered For New Project In Sweden
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Freja Offshore, a joint venture between Hexicon and Mainstream Renewable Power, has submitted an application for an offshore wind farm in Sweden that could have an installed capacity of between 2 GW and 2.5 GW and, according to the project’s consultation document, could feature wind turbines of up to 30 MW per unit.
This paragraph, indicates how turbines have grown over the last two decades.
The wind turbines in the future will probably be taller, the rotor diameter larger and the turbines more powerful, the joint venture says in the consultation document, and compares the largest wind turbines launched in 2011, which have a rotor diameter of 164 metres and an installed capacity of 8 MW, with those launched 10 years later, featuring a rotor diameter of 236 metres and an output of 15 MW.
Moving on a few years to 2030 and it doesn’t seem unreasonable that turbine size will double again to 30 MW.
I could see them becoming the standard turbine, providing they aren’t too heavy for the fixed foundations or floats.
It would be an interesting exercise to model the costs of wind farms, as the turbines get bigger.
With North Sea oil and gas, I was told several times, by Artemis users, that as cranes got larger, which allowed bigger lifts, the costs of offshore infrastructure decreased.
Note.
New Rolls-Royce Small Engine Set To Begin Tests To Advance Hybrid-Electric Flight
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the first two paragraphs.
Rolls-Royce today announces its new small gas turbine that has been specifically developed to power hybrid-electric flight is set to begin testing. The engine is part of a turbogenerator system that is being developed for the Advanced Air Mobility market. This includes electrical vertical take-off and landing (eVTOL) Aircraft for Urban Air Mobility and Commuter Aircraft applications up to 19 seats.
The turbogenerator system will complement the Rolls-Royce Electrical propulsion portfolio by delivering an on-board power source with scalable power offerings between 500kW and 1200kW enabling extended range on sustainable aviation fuels (SAF) and later, as it becomes available, through hydrogen combustion. This will open up new, longer routes than electric battery powered aircraft can support as of today.
The press release also lays out these design targets.
- Power – 600-1200 kW
- Voltage – 850 Volts
- Power to Weight Ratio – 4 kW/Kg
- Noise – 62 dbA
- Specific Fuel Consumption v in-service products – 15% better
- MTBO – 10,000 cycles
- Length – 1,500 mm.
- Diameter – < 500 mm.
Note.
- At first look, it appears to be small and powerful.
- If they can meet the Power to Weight Ratio of 4 kW/Kg, this would mean that a 1200 kW engine will weigh just 300 Kg.
- The engine has been designed to run on sustainable aviation fuel and hydrogen.
I wouldn’t be surprised to see this engine used in non-aviation applications.
Grain LNG Launches Market Consultation For Existing Capacity
The title of this post is the same as that of this press release from National Grid.
This is the sub-heading.
Grain LNG, the largest liquefied natural gas (LNG) terminal in Europe, is pleased to announce the launch of a market consultation for the auction of 375 Gwh/d (approx. 9 mtpa) of existing capacity. The initial consultation phase for the Auction of Existing Capacity will commence on 14 June and run until 26 July.
These paragraphs detail what Grain LNG, which is a subsidiary of National Grid are offering.
GLNG has used the positive feedback received from the recent ‘Expression of Interest’ exercise and subsequent market engagement to offer three lots of capacity:
- Each lot will be entitled to 42 berthing slots, 200,000 m3 of storage and 125GWh/d (approx. 3 mtpa) of regasification capacity from as early as January 2029.
- This product is specifically designed for parties who wish to acquire a substantial stake in a major terminal in Northwest Europe, at a reduced cost and with shorter contract lengths when compared to new-build projects.
- As the terminal’s capacity already exists, parties involved will not be subjected to the FID approvals or potential delays that can arise from construction issues commonly associated with new build terminals.
Simon Culkin, Importation Terminal Manager at Grain LNG, said: “We are really pleased with the high level of interest shown by the market at a time of significant geo-political influence on our energy markets. It has allowed us to engage with potential customers and shape our offering to best meet their needs, whilst optimising access to this strategic asset. “
Reading the Wikipedia entry for the Grain LNG Terminal, it looks like it gets used as a handy store for natural gas.
About Phase 1 (2002–05), Wikipedia says this.
The new facilities enabled the Grain terminal to become a base supply to the NTS, with the ability to deliver gas continuously when required. The cost of the Phase 1 project was £130m. A 20-year contract with BP / Sonatrach enabled Grain LNG to import LNG on a long-term basis from July 2005.
About Phase 2 (2005–08), Wikipedia says this.
The development provided an additional five million tonnes of capacity per annum. All this capacity was contracted out from December 2010. Customers included BP, Iberdrola, Sonatrach, Centrica, E.ON and GDF Suez.
Under Current Facilities, Wikipedia says this.
Grain LNG Ltd does not own the LNG or the gas that it handles but charges for gasifying it. Current (2016) users include BP, Centrica (British Gas Trading), Iberdrola (Spain), Sonatrach (Algeria), Engie (France), and Uniper (Germany).
National Grid must be pleased that some customers seem loyal.
I feel that National Grid’s basic plan is to carry on with more of the same.
But will they develop more storage and other facilities on the site.
There are certainly other projects and interconnectors, that make the Isle of Grain and energy hub connecting the UK, Netherlands and Germany.
- In Did I See The UK’s Hydrogen-Powered Future In Hull Today?, I mentioned, that I thought that the Isle of Grain could be a location for an electrolyser and a hydrogen store.
- In EuroLink, Nautilus And Sea Link, I talk about new interconnectors, if which Nautilus might come to the Isle of Grain.
- In UK-German Energy Link Reaches Financial Close, I talk about NeuConnect, which will be an interconnector between the Isle of Grain ans Wilhelmshaven in Germany.
- The Isle of Grain is the landing point for the BritNed undersea power cable between The Netherlands and the UK.
I could also see National Grid building an East Coast interconnector to bring power from the wind farms off the East Coast of England to the Isle of Grain for distribution.
These are major wind farms South of the Humber.
- Dudgeon – 402 MW
- East Anglia 1 – 714 MW
- East Anglia 1 North – 800 MW
- East Anglia 2 – 900 MW
- Galloper – 504 MW – RWE
- Greater Gabbard – 504 MW
- Gunfleet Sands – 174 MW
- Hornsea 1 – 1218 MW
- Hornsea 2 – 1386 MW
- Hornsea 3 – 2852 MW
- Humber Gateway – 219 MW
- Lincs – 270 MW
- London Array – 630 MW
- Lynn and Inner Dowsing – 194 MW
- Race Bank – 580 MW
- Scroby Sands – 60 MW
- Sheringham Shoal – 317 MW
- Triton Knoll – 857 MW – RWE
- Dogger Bank A – 1235 MW
- Dogger Bank B – 1235 MW
- Dogger Bank C – 1218 MW
- Dogger Bank D – 1320 MW
- Dogger Bank South – 3000 MW RWE
- East Anglia 3 – 1372 MW
- Norfolk Boreas – 1396 MW
- Norfolk Vanguard – 1800 MW
- Outer Dowsing – 1500 MW
- North Falls – 504 MW – RWE
- Sheringham Shoal and Dudgeon Extensions – 719 MW
- Five Estuaries – 353 MW – RWE
Note.
- These figures give a total capacity of 28,333 MW.
- Five wind farms marked RWE are owned by that company.
- These five wind farms have a total capacity of 5618 MW.
- Will RWE export, their electricity to Germany through NeuConnect?
I can certainly see National Grid building one of the world’s largest electrolysers and some energy storage on the Isle of Grain, if an East Coast Interconnector is built.
SSE Renewables Calls For More Use Of Non-Price Criteria In Offshore Wind Auctions
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
SSE Renewables is calling on European governments and regulators and internationally to make greater use of non-price criteria (NPC) in offshore wind energy auctions, whether for seabed or for contracts for difference (CfD).
This is the first paragraph.
The renewable energy company said that the use of non-price criteria in auctions for new offshore wind can help support a sustainable renewable energy sector that delivers long-term value for society.
This document on the SSE Renewables web site is entitled Non-Price Criteria In Renewables Auctions and these are the points from the Executive Summary from the document.
- Use of non-price criteria (NPC) in auctions is important to deliver renewables projects which are deliverable, on time and on budget, and provide long term value to society and the environment.
- NPC must be well-designed, carefully implemented, with transparent assessment and monitoring of commitments to avoid overcomplication and risk of legal challenges.
- Seabed leasing auctions for offshore wind are best suited for use of NPC, as it is early enough in the development stage for commitments to be delivered; and avoids having to rely on purely financial bidding which risks adding to the cost of offshore wind.
- The most appropriate NPC are track record and deliverability of projects. Beyond that, criteria related to sustainability (circularity; workforce and skills); ecological protection and enhancement; and supply chain development.
- NPC in new offshore wind markets should be focused on deliverability and track record, and included as a pre-requisite to participate, rather than a point of competition.
- More diverse non-price criteria are best suited to mature offshore wind markets where there will generally be more competition from developers to build a project.
- It is more complicated to apply non-price criteria into offtake (CfD) auctions, with re-ranking of bidders the best approach to properly incentivise the right behaviour.
- It is important that there is transparency of how successful bidders were scored against NPC; what commitments have been made and how they will be held accountable for delivery at different milestones.
Note.
- It is good to see phrases like “track record and deliverability of projects” being embedded in this list of points.
- As a designer of successful project management software, I know the importance of this.
- I believe, that SSE Renewables are right to desire wider criteria for offshore wind energy auctions.
I suspect too, that there are software ideas in my past, that would make the development of offshore wind easier and more predictable.
Shell And Eneco Joint Venture Looks To Build Greener Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ecowende, the joint venture (JV) of Shell and Eneco, has unveiled plans for building an offshore wind farm that will be in harmony with nature, with minimal impact on birds, bats, and marine mammals.
This is the first paragraph.
Ecowende, which presented its holistic approach at WindDay 2023, said it is going to implement various innovations, large-scale mitigating and stimulating ecological measures, and an extensive above and under-water monitoring and research programme.
This is all good stuff.
These two paragraphs outline some ideas that will be tried.
Specific measures include increasing the height of the lowest tip of the rotor blades, creating a corridor to Natura 2000 area by placing the turbines extra far apart, and an option to bring the turbines to a standstill that adapts to the flight movements of birds in the wind farm.
This way, Ecowende expects to minimise the number of bird and bat collisions.
The Natura 2000 areas are described in this web site.
Other innovative ideas are described in these two paragraphs.
Biodegradable reef structures are being constructed using fruit trees sourced from Dutch fruit farms. These tree reefs offer a place for fish to shelter and reproduce, according to the press release.
Ecowende said it will also install various forms of eco-friendly erosion protection and the oyster larvae network will be expanded to spread the native flat oyster population.
It certainly looks like Ecowende are making sure, that Just Stop Oil’s offshoot; Just Stop Wind doesn’t take root!
