Gravity—Yes, Gravity—Is the Next Frontier for Batteries
The title of this post, is the same as that of this article on Popular Mechanics.
This is the first paragraph.
When the sun isn’t shining and the wind isn’t howling, suspended weights can step in to generate power.
The article goes on to explain Energy Vault and Gravitricity.
It is certainly an endorsement of the technique from one of America’s popular magazines.
Cost Of Turning Off UK Wind Farms Reached Record High In 2021
The title of this post, is the same as that of this press release from Drax.
This is the first paragraph.
The cost of turning off wind farms in the UK has reached record levels, according to a new report.
The press release makes these points.
- Investing in more long duration electricity storage, such as expanding Drax’s Cruachan pumped storage hydro plant in Scotland, would mean more excess renewable power could be stored and made available when required, cutting costs and carbon emissions.
- The cost of turning off UK wind farms to manage the electricity system rose from almost £300m during 2020 to over £500m in 2021, contributing to higher energy bills and carbon emissions, according to a new report.
- Costs increased substantially because the system relied on expensive gas power to manage periods when wind power was curtailed, as not enough electricity storage was available to prevent the excess renewable power from wind farms going to waste.
Drax give these reasons for the problems.
This happened as a result of constraints in the transmission system and a lack of long-duration storage capacity, which is needed to manage periods when renewable power generation outstrips demand.
The problem is going to get worse as we increase the amount of wind power in the UK.
Penny Small, Drax’s Group Generation Director sums everything up.
This report underlines the need for a new regulatory framework to encourage private investment in long-duration storage technologies.
The UK is a world-leader in offshore wind, but for the country’s green energy ambitions to be realised we need the right energy storage infrastructure to support this vital technology, make the system secure and reduce costs.
Drax’s plan to expand Cruachan will strengthen UK energy security, by enabling more homegrown renewable electricity to power British homes and businesses, reducing system costs and cutting carbon emissions.
A good framework has been created for wind farms and many more are being proposed and developed.
Frameworks are needed for both transmission systems and long-duration energy storage capacity.
Drax To Pilot More Pioneering New Carbon Capture Technology
The title of this post, is the same as that of this press release from Drax.
This is the first paragraph.
Renewable energy pioneer Drax has partnered with the University of Nottingham and Promethean Particles to trial a pioneering new bioenergy with carbon capture and storage (BECCS) process at its North Yorkshire power station.
Normally, carbon capture from the flue gas of a power station uses a liquid solvent, which dissolves the carbon dioxide.
However, the process that Drax are trialling, uses porous compounds called metal–organic frameworks (MOFs) to absorb the carbon dioxide.
This page on the Promethean Particles web site described how their carbon-capture works.
Traditional solvent-based carbon capture systems require a significant amount of energy to regenerate the carbon-capturing material. In power generation applications, estimates put this energy penalty at up to 35% of the power station’s output. Metal-organic frameworks (MOFs) capture carbon mainly through physical, not chemical means. This “trapping” process requires lower energy inputs to regenerate the MOFs and can therefore help achieve more energy-efficient carbon capture. By using MOF-based carbon capture, more of the power generated can go where it was intended, lowering the price of energy for consumers and CAPEX for the power generators.
Note.
- It is a physical rather than a chemical process.
- It is more energy efficient than traditional carbon-capture.
This Drax graphic from the press release, shows how this process can be incorporated into a power plant..
Note.
- The trial will last for two months and will be hosted within Drax’s BECCS incubation hub at its North Yorkshire Power Station.
- Metal Organic Frameworks are a unique class of solid sorbents offering lower operational costs and reducing potential environmental impacts.
Work to build BECCS at Drax could get underway as soon as 2024, with the creation of thousands of jobs.
Fifty years ago, I spent several months at ICI looking at the mathematics of different numbers and sizes of vessels of in a proposed chemical plant, to optimise the cost of the plant.
- I suspect a similar analysis could be applied to this process.
- It would surely be very suitable for Drax, whose main power station has four units fuelled by biomass and another fuelled by natural gas.
- Are two columns containing MOF, the optimum number?
- The calculation could involve a lot of permutations and combinations, which I’ve used to advantage for over fifty years.
I will follow this trial with interest.
Conclusion
This is another application of advanced physics and chemistry.
If Promethean Particles ever decide to go the crowdfunding route, I would look seriously at a small investment.
Equinor And Partners Consider 1 GW Offshore Wind Farm Off The Coast Of Western Norway
The title of this post, is the same as that of this press release from Equinor.
This is the first paragraph.
Equinor and its partners Petoro, TotalEnergies, Shell and ConocoPhillips in the Troll and Oseberg fields, have initiated a study and are looking into possible options for building a floating offshore wind farm in the Troll area some 65 kilometres west of Bergen, Norway.
This second paragraph describes the production and use of the electricity.
With an installed capacity of about ~1 GW and an annual production of ~4.3 TWh, with a startup in 2027, Trollvind could provide much of the electricity needed to run the offshore fields Troll and Oseberg through an onshore connection point. The Bergen area already serves several of these installations with power – and needs more input to its electricity grid. The plan is that the partnership will buy as much energy as the wind farm can produce at a price that can make the project possible.
The press release includes a map of the wind farm, the oil and gas fields and Bergen.
This is not the first time, I’ve heard of plans to use wind-generated electricity to power offshore oil and gas fields.
It could be argued that if the gas is sold to the UK or Germany, then that country is responsible for the carbon emissions.
I doubt that Vlad the Mad’s bloodstained gas is produced using a carbon-free process.
Intriguing “Frozen Air” Energy Storage In Vermont Gets Canned
The title of this post, is the same as that of this article on the Concord Monitor.
This is the first paragraph.
Alas, the company Highview Power has given up on a plan I wrote about in 2019 to develop a long-term energy storage project in northern Vermont that freezes and unfreezes air.
The author had asked Highview Power for an update and received this statement.
As a UK-based company our primary focus right now is on our Carrington project in the North of England. This will be our first commercial plant in the wider development of a 45GWh, £10 billion programme in the UK. While the Vermont project no longer remains in our current plans, we are developing a longer-term portfolio of projects in Spain, Australia, and the U.S and we look forward to pushing forward with these after we achieve our primary UK projects.
It sounds to me that the new CEO; Rupert Pearce, is simplifying the company’s operations and aiming to get the important Carrington plant working as a priority.
Nuclear-Enabled Hydrogen – How It Helps To Reach Net Zero
The title of this post, is the same as that of this article on Power Engineering.
These are the first two paragraphs.
Nuclear enabled hydrogen is zero carbon, has low cost energy input, is large scale and offers co-location synergy and energy system connectivity.
With the revival of interest in nuclear energy, interest is growing in the potential for nuclear-enabled hydrogen, otherwise sometimes known as ‘pink’ hydrogen, to meet the anticipated demand for hydrogen at scale.
The article is certainly a must-read.
Topics covered include.
- Co-location of pink hydrogen production with industrial clusters, where heat can also be provided.
- The production of hydrogen on a large scale.
- The use of high temperature electrolysis, using steam from the nuclear plant.
I particularly like the idea of combining a small modular nuclear reactor with high temperature electrolysis to generate hydrogen for local industry like a steelworks or chemical plant.
Vast Australian Renewable Energy Site Powers BP’s Ambitions
The title of this post, is the same as that of this article on The Times.
These are the first two paragraphs.
BP is to lead the development of a $36 billion wind, solar and hydrogen project in Western Australia in its latest foray into green energy.
The oil company has bought a 40.5 per cent stake in the Asian Renewable Energy Hub in the eastern Pilbara region and will become operator of the project, one of the biggest such developments globally.
The Wikipedia entry for the Asian Renewable Energy Hub, starts like this.
The Asian Renewable Energy Hub (AREH) is a proposal to create one of the world’s largest renewable energy plant in the Pilbara region of Western Australia. It was first proposed in 2014, with plans for the project concept changing several times since then. As of November 2020, the project developers Intercontinental Energy, CWP Global, Vestas and Pathway Investments were planning to build a mixture of wind power and solar energy power generators which would generate up to 26 gigawatts of power.
Up to 1,743 wind turbines of 290 metres (950 ft) in height would be accommodated in 668,100 hectares (1,651,000 acres) of land, and 18 arrays of solar panels each generating 600 megawatts would cover 1,418 hectares (3,500 acres). It is to be located in the Shire of East Pilbara, about 30 km (19 mi) inland from 80 Mile Beach, with the nearest settlement on the map being Mandora Station. The total size of the scheme would be about 666,030 ha (1,645,800 acres).
It is a gigantic project and this Google Map of Western Australia shows its location.
It is no more than a pimple on the huge area of Western Australia.
I have my thoughts about BP getting involved with this project.
The Power Of Research
Around 1970, I spent four years in ICI applying mathematical methods to some of their processes, that were in research or development. I also worked for a time on their hydrogen plants. Some of the projects I heard about, were pretty wacky and some of these appear to have never been commercialised.
When I left ICI, I built a few mathematical models for other research organisations.
So I do wonder, if BP have found something, that will enable the process of making hydrogen from water a lot more efficient. There is an American startup called Bloom Energy, who have teamed up with Westinghouse to use steam from the nuclear reactor to do electrolysis more efficiently at a high temperature.
I wrote about this partnership in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen, where Bloom Energy Vice President of Hydrogen Business Rick Beuttel, is quoted as saying this.
We are proud Westinghouse has turned to Bloom and our solid oxide technology to supercharge the clean hydrogen economy. Solid oxide technology is well suited for nuclear applications, efficiently harnessing steam to further improve the economics of hydrogen production. High temperature electrolysis is already garnering attention and accolades as a cost-effective and viable solution to create low-cost, clean hydrogen, which is critical to meeting aggressive decarbonization goals.
It sounds that by integrating the nuclear power station and the electrolyser, there are cost savings to be made.
Why not use solar power to create steam, which is called solar thermal energy and is used in various hot places in the world and then use high temperature electrolysis?
I suspect that BP are up to something, that is very similar to Fortescue Future Industries in the Australian company’s back yard.
So will they be selling the hydrogen to FFI, so they can market it together all over the world?
This BP deal is one to watch.
Has The NorthConnect Interconnector Been Binned?
If you type “NorthConnect interconnector” into Google and select News, the latest stories are from March 2020.
One story from that date is this article on Energy Live News, which is entitled Norway Postpones Decision On Interconnector To Scotland.
These are the first three paragraphs.
The Norwegian Ministry of Petroleum and Energy (MPE) has postponed a decision on whether to allow the construction of a new subsea power cable between Norway and Scotland.
The 1,400MW Project NorthConnect, which is partly owned by Swedish energy group Vattenfall, has been put on hold pending public consultation and performance and cost reviews of similar projects under construction.
Minister of Petroleum and Energy Tina Bru, said: “The Norwegian and Nordic power system is going through significant changes, at a rapid pace. Two new interconnectors, to the UK and Germany respectively, will be commissioned in the near future.
The NorthConnect web site has some community news from last year.
So has this project been binned?
Westinghouse And Bloom Energy To Team Up For Pink Hydrogen
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the introductory paragraph.
Westinghouse Electric Company and Bloom Energy Corporation have announced that they have signed a letter of intent together for the production of pink hydrogen in the commercial nuclear power market.
Note.
- Westinghouse Electric Company is an American builder of nuclear power stations.
- Bloom Energy Corporation make a solid-oxide electrolyser.
- Pink hydrogen is green hydrogen produced using nuclear power.
Figures on the Bloom web site, claim that their electrolysers could be upwards of twelve percent more efficient than PEM electrolysers, as produced by companies like ITM Power.
Bloom Energy Vice President of Hydrogen Business Rick Beuttel, is quoted as saying this.
We are proud Westinghouse has turned to Bloom and our solid oxide technology to supercharge the clean hydrogen economy. Solid oxide technology is well suited for nuclear applications, efficiently harnessing steam to further improve the economics of hydrogen production. High temperature electrolysis is already garnering attention and accolades as a cost-effective and viable solution to create low-cost, clean hydrogen, which is critical to meeting aggressive decarbonization goals.
It sounds that by integrating the nuclear power station and the electrolyser, there are cost savings to be made.
Conclusion
I think this could turn out to be a significant development.
Some countries, like Iceland, Indonesia, New Zealand, Philippines and the United States, who can generate large amounts of electricity and steam from geothermal energy, Bloom’s technology must surely be a way of electrolysing hydrogen.
ElecLink: A Wholly Successful First Week Of Operations
The title of this post, is the same as that of this press release from the Getlink Group.
These are the first three paragraphs.
Getlink is delighted with the good first week of commercial operations of its electrical interconnector, ElecLink, marked by the success of the initial auctions and the first transfers of energy through the cable.
The first auctions for short term capacity (day ahead) held since 24 May were met with great success. The entire capacity available was sold, confirming the interest of the sector for this new interconnection. The first monthly auctions will take place from 01 June, for the month of July and will be accessible via the JAO platform.
From an operational perspective, the go-live of the cable was also achieved successfully. For this world’s first, ElecLink delivered an excellent quality of service to its customers.
Note.
- Getlink is the manager and operator of the Channel Tunnel.
- ElecLink has a capacity of 1,000 MW.
- The interconnector was privately-funded.
I wouldn’t be surprised to see more privately-funded interconnectors like this, as they increase our energy security and can be a nice little earner for their owners.
