DuPont Introduces First Ion Exchange Resin For Green Hydrogen Production
The title of this post, is the same as that of this press release from DuPont.
This is the sub-heading.
Newly designed ion exchange resin with extended service time designed to enhance electrolyzer operation
This is the first paragraph.
DuPont today announced the launch of its first product dedicated to the production of green hydrogen – the DuPont™ AmberLite™ P2X110 Ion Exchange Resin. To support the production of hydrogen from water, this newly available ion exchange resin is designed for the unique chemistry of electrolyzer
Put simply, it appears, that DuPont’s new product will improve the overall efficiency of the electrolysis of water to produce hydrogen.
New Rolls-Royce Engine For Hybrid-Electric Flight Completes Successful First Fuel Burn
The title of this post is the same as that of this press release from Rolls-Royce.
This is the sub-heading.
A new Rolls-Royce small gas turbine that has been specifically developed to power hybrid-electric flight has successfully completed its first fuel burn. The engine has been designed using novel combustion technology to produce ultra-low emissions and this significant achievement confirms the effectiveness of the compact, power-dense turbine that will be integrated into a light-weight turbogenerator system.
This first paragraph gives more details.
The complete turbogenerator system is being developed for the Advanced Air Mobility (AAM) market. This includes electrical vertical take-off and landing (eVTOL) or electric short take-off and landing (eSTOL) aircraft for Urban Air Mobility (UAM) and commuter aircraft applications up to 19 seats. The gas turbine under test also has potential applications within helicopter, auxiliary power unit (APU) and defense markets.
Looking at Wikipedia, it appears that a typical 19 seat airliner needs two engines with a power between 500 and 600 kW.
This would fit with the next paragraph of the press release.
The turbogenerator system will complement Rolls-Royce’s electrical propulsion portfolio by delivering an on-board power source with scalable power offerings between 500 kW and 1,200 kW enabling extended range on sustainable aviation fuels and later, as it becomes available, through hydrogen combustion. This will open up new, longer routes than electric battery powered aircraft can support today.
I can envisage electric 19-seat airliners powered by either two 600 kW engines or one 1200 kW engine.
But then the mind boggles at the applications for this range of engines.
Scotland’s 25 GWh Energy Storage Arriving By Stealth
In SSE Unveils Redevelopment Plans For Sloy Hydro-Electric Power Station, I introduced SSE Renewable’s plan to convert the UK’s largest hydro-electric power station into a pumped storage hydroelectric station, that can store 25 GWh of electricity and generate 152.5 MW of electricity.
After a public consultation in July, which unfortunately, I was unable to get to, SSE have now published a comprehensive document, which details their plans.
These are some points from the document.
- There will be no increase in the generating capacity of 152.5 MW, which is about half the size of a gas-fired power station.
- SSE designed a similar scheme for Sloy in 2009.
- Pumped storage systems need a lot of water. The Loch Sloy scheme has Loch Lomond.
- The development of pumped storage at Sloy would only require construction work to be carried out in the grounds of the existing power station.
- No permanent new works would be required at Sloy Dam or outside of the existing station boundary.
- A new above ground structure would be required which would contain a main hall with vehicular access, laydown areas, an overhead travelling crane, electrical switchgear and control systems.
- A new underground pump hall would be required to house two pumps. This would link to the intake structure and would be approximately 20m below the existing ground level.
- The existing tailrace to Loch Lomond, will be used to bring water to the pumps.
- Construction could start in 2025, with completion in 2027.
This redevelopment is a much less complex construction project, than building the original power station in the 1950s.
It also looks like the construction will not cause much disruption in the local area.
Hence my view, that this storage is arriving by stealth and won’t be noticed by those passing the power station.
After reading this SSE document, I wonder how many similar 1950s hydroelectric power stations have been upgraded to pumped storage stations in the last few years.
Also, if their Sloy scheme is successful, will SSE be looking for other hydroelectric power stations to convert to pumped storage?
This article on renews.biz is entitled Vattenfall Plans To Build 730MW Of Swedish Hydro Power, where this is a paragraph.
Vattenfall is also conducting a pilot study to investigate reinstating the Juktan power station on the Storjuktan lake adjacent to the Umeälven river in Västerbotten, to a pumped storage plant with a capacity of up to 380MW.
Note.
- Juktan power station was built as a pumped storage station and converted to a standard one.
- It has a web page.
- As the paragraph says it could be converted back!
So other companies and countries are thinking the same way!
Strathclyde University’s Prediction
This page on the Strathclyde University web site, gives these figures in GWh for the possible amounts of pumped storage that can be added to existing schemes.
- Errochty – 16
- Glasgarnock – 23
- Luichart – 38
- Clunie – 40
- Fannich – 70
- Rannoch – 41
- Fasnakyle – 78
- Tummel – 38
- Ben Lawers – 12
- Nant – 48
- Invermoriston – 22
- Invergarry – 41
- Quoich – 27
- Sloy – 20
That is a total of 514 GWh.
These figures must give SSE food for thought.
These new schemes are also being planned.
- Balliemeanoch – 1.5GW/45 GWh
- Coire Glas – 1.5 GW/30 GWh
- Corrievarkie – 600 MW/14.5 GWh
- Fearna – 1.8 GW/37 GWh
- Loch Earba – 900 MW/33 GWh
- Loch Kemp – 300 MW/9 GWh
- Loch Na Cathrach/Red John – 450 MW/2.8 GWh
These could bring the potential pumped storage in Scotland to 685.3 GWh.
ILI Group To Develop 1.5GW Pumped Storage Hydro Project
The title of this post, is the same as that of this article on the Solar Power Portal.
This is the sub-heading.
The pumped hydro facility will be located at Loch Awe, which is also home to Kilchurn Castle.
These paragraphs outline the story.
Clean energy developer ILI Group has begun the initial planning phase for a new pumped storage hydro project in Scotland.
The Balliemeanoch project at Loch Awe, Dalmally in Argyll and Bute will be able to supply 1.5GW of power for up to 30 hours. It is the third and largest of ILI’s pumped storage hydro projects, with the other two being Red John at Loch Ness and Corrievarkie at Loch Ericht.
The Balliemeanoch project will create a new ‘head pond’ in the hills above Loch Awe capable of holding 58 million cubic meters of water when full.
Note.
- At 1.5 GW/45 GWh, it is a large scheme and probably the largest in the UK.
- This is the third massive pumped storage hydro scheme for the Highlands of Scotland after SSE’s 1.5 GW/30 GWh Coire Glas and 152 MW/25 GWh Loch Sloy schemes.
- I describe the scheme in more detail in ILI Group To Develop 1.5GW Pumped Storage Hydro Project.
The article also has this paragraph.
It follows a KPMG report finding that a cap and floor mechanism would be the most beneficial solution for supporting long duration energy storage, reducing risks for investors while at the same time encouraging operators of new storage facilities to respond to system needs, helping National Grid ESO to maintain security of supply.
A decision on funding would be helpful to all the energy storage industry.
Rolls-Royce And Zero Petroleum Join Forces To Develop Sustainable Future
The title of this post, is the same as that of this press release from Rolls Royce.
This is the sub-heading.
Rolls-Royce has entered a landmark agreement with breakthrough Energy company Zero Petroleum to promote further development of the company’s power and propulsion solutions with fossil-free synthetic fuels.
These two paragraphs outline the agreement.
The new agreement will see the two parties collaborate to demonstrate Rolls-Royce engines for aviation, marine and defence with Zero® synthetic fuels.
This has the potential to include Zero’s entire range of synthetic fuels – petrol, diesel and jet fuel – with data gathered from engine testing used to prove the credentials required to achieve international fuel certification standards. Synthetic fuels deployed by Rolls-Royce in engine tests will directly reduce associated carbon emissions.
Are Rolls-Royce going to do their engine testing using synthetic fuels to reduce their carbon emissions?
It certainly looks like they might and I suppose it does two tests at the same time.
Rolls-Royce Seem To Be Using Technology To Save The Company
Big companies like Rolls-Royce, who are very much toed up with fossil fuels have two options; give up or fight using the only weapons they have; superb technology and a lot of experience.
There are only a small group, that seem to be fighting to succeed. To Rolls-Royce, I would add Cummins, Fortescue Future Industries, Ricardo and SSE, and possibly BP and Centrica.
Scottish Project To Explore Tugdock Tech Application To Accelerate Floating Wind Development
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The joint venture behind the Salamander floating wind project and the UK developer of marine buoyancy technology, Tugdock, have signed a memorandum of understanding (MOU) to collaborate on research and innovation related to the development of technologies and supply chain for floating wind energy in Scotland.
This is the introductory paragraph.
The 100 MW floating wind farm, developed jointly by Simply Blue Group and Ørsted, and Subsea7 as a minority partner, is one of the 13 projects selected in Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round and one of the five INTOG innovation projects which signed exclusivity agreements with Crown Estate Scotland in May.
There is more about Tugdock on their web site.
I like the concept, but then I did a lot of simulation of floating structures in the 1970s, which I wrote about in The Balaena Lives.
UK Investor Takes Stake In Hornsea Two Transmission Assets
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
London-based international investor and manager, John Laing Group, has acquired a stake in the transmission assets for the 1.3 GW Hornsea Two offshore wind farm in the UK, as part of a portfolio acquisition from HICL Infrastructure.
These two paragraphs outline the deal.
John Laing Group has agreed to acquire HICL Infrastructure’s entire equity interest in four UK public-private partnership projects, including a 37.5 per cent stake in the Hornsea Two offshore transmission assets for a total consideration of GBP 204 million (EUR 236 million).
All five acquisitions are expected to be completed before the end of March 2024.
I wrote World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant in November 2018.
Funds and investors with money don’t seem to be losing their appetite for assets, that can provide a regular income.
Wrightbus To Provide Hydrogen Buses For Sizewell C Nuclear Plant
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Ballymena bus manufacturer Wrightbus is providing four hydrogen buses to the Sizewell C nuclear power site as part of a pilot scheme.
These first three paragraphs outline the scheme.
If successful, up to 150 buses could be ordered, making it one of the largest hydrogen bus fleets in the world.
Construction of the plant is to begin next year and multiple vehicles will be needed to move workers to and from the site.
Sizewell C will test the performance of four double-decker buses.
As I used to live in that area, I know the buses are bad and this will surely help.
Biggest Untapped UK Oil Field, Rosebank, Approved By Regulators
The title of this post, is the same as that of this article on the BBC.
This is the BBC’s summary so far.
- The UK’s largest untapped oil field has been approved by regulators
- Rosebank, 80 miles west of Shetland, is estimated to contain 500 million barrels of oil
- The UK government welcomes the decision, saying it will raise billions of pounds and “make us more secure against tyrants like Putin”
- But Scotland’s First Minister Humza Yousaf says he’s “disappointed”, while the Green Party calls the decision “morally obscene”
- Regulators said net zero considerations had been taken into account
This is my summary.
I have been reading Equinor’s web site on Rosebank.
Production will use what is known as a Floating Production Storage and Offloading Vessel or FPSO, which means, when they’ve finished, it can just sail away.
The FPSO will also be electrification-ready, so that all operations on the vessel will probably be powered by green electricity from a nearby wind farm, instead of by a gas turbine engine on the vessel, which burns gas.
This means that the offshore operations will be as carbon-free as is reasonably possible. But importantly, we will pipe the maximum amount of gas from the field for either our own use or selling to the gas-thirsty Germans.
We will need the gas for some time to back up wind and solar with gas-fired power stations.
But what about the emissions from the power stations?
Capturing carbon dioxide from a power station is getting easier, but more importantly, researchers are finding more and more innovative ways of using the carbon dioxide.
H & M and Zara are even selling clothes made from captured carbon dioxide.
Ways are also being developed using plasma electrolysis to strip the carbon out of natural gas to leave useful hydrogen.
Natural gas will be our friend for many decades yet, if we can turn it into a zero-carbon fuel, which I believe we can!
Fourth Phase Could Bring 2 GW More To World’s Already Largest Offshore Wind Farm Under Construction
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dogger Bank D, the potential fourth phase of the Dogger Bank Wind Farm, whose first three phases totalling 3.6 GW are currently being built, is planned to have a generation capacity of around 2 GW. If built, the fourth phase would bring the total installed capacity of the UK project – already the world’s largest offshore wind farm under construction – to over 5.5 GW.
This is the introductory paragraph.
SSE Renewables and Equinor, which own the Dogger Bank A, B and C offshore wind farms through a consortium that also comprises Vårgrønn, have now launched a public consultation period on the Dogger Bank D proposals that runs until 7 November.
As RWE are developing the 3 GW Dogger Bank South, the Dogger Bank wind farm will be up to 8.5 GW in a few years.
