Could Drax Power Station Solve The Carbon Dioxide Shortage?
Drax Power station is the largest power station in the UK, with a 2.6 GW capacity when burning biomass.
It has also been a regular target of environmental activists complaining of the power station’s carbon dioxide and other emissions.
But could it be an unlikely saviour to replace the carbon dioxide that comes from two fertiliser plants run by the CF Industries, that have been shut down by high gas prices?
I wrote about the shortage in Food Shortages Looming After Factory Closures Hit Production.
Two and a half years ago I wrote Drax Becomes First Wood-Burning Power Plant To Capture Carbon, which was based on an article in the Financial Times.
I said this about the report.
This news has been treated in a more sensationalist way by other news media and sites, but the FT gives it very straight.
Drax power station is running an experiment, that removes a tonne of carbon dioxide a day.
But that is only the start of the process and most of it is released to the atmosphere.
They are currently, looking for profitable and environmentally-friendly ways of disposal, including selling it to beer manufacturers.
Didn’t we have a carbon-dioxide shortage a few months ago?
Now is probably a good time to dig a little deeper into what Drax is doing.
The Wikipedia entry for Drax power station has a section called Carbon Capture And Storage.
This is the last paragraph of the section.
In May 2018, Drax announced a new carbon capture and storage pilot scheme that it would undertake in conjunction with the Leeds-based firm, C-Capture. The focus of this pilot will be on capturing carbon post combustion from the biomass burners as opposed to the coal burners. Drax will invest £400,000 into the project. The company, C-Capture, is a side company of the Department of Chemistry established at the University of Leeds. This would yield about 1-tonne (1.1-ton) of CO2 stored per day from the process, which could be sold on for use in the drinks industry. The pilot scheme was launched in February 2019. The capture of carbon from biomas burners is known as Bio Energy with Carbon Capture and Storage (BECCS).
Who are C-Capture?
Their web site is very informative and this page is called Our Story, which explains the project at Drax.
We designed, built, and installed a pilot plant and have been operating it on site, with real flue gas, since early 2019. The data gathered from this trial is feeding directly into the design process for a full-scale plant, with a target of 10,000 tonnes of CO2 per day captured from one of Drax’s four biomass fired boilers. A recent development has been the installation of equipment to bottle the captured CO2 to allow other organisations to test their own developing technologies with genuine Drax derived CO2.
That looks like a result to me for C-Capture.
This page is called Technology and has a very neat interactive guide to how the technology works.
Conclusion
This company has some very special technology, that has a lot of applications.
It is also significant that Drax and BP have taken a shareholding in C-Capture.
Is Carbon Dioxide Not Totally Bad?
To listen to some environmentalists, there views on carbon dioxide are a bit like a variant of George Orwell’s famous phrase Four legs good, two legs bad from Animal Farm, with carbon dioxide the villain of the piece.
I have just read the Wikipedia entry for carbon dioxide.
For a start, we mustn’t forget how carbon dioxide, water and sunlight is converted by photosynthesis in plants and algae to carbohydrates, with oxygen given off as waste. Animals like us then breathe the oxygen in and breathe carbon dioxide out.
Various web sites give the following information.
- The average human breathes out 2.3 pounds of carbon dioxide per day.
- As of 2020, the world population was 7.8 billion.
This means humans breathe out 17.94 billion pounds of CO2 per day
This equates to 6548.1 billion pounds per year or 2.97 billion tonnes per year.
And I haven’t counted all the other animals like buffalo, cattle, elephants and rhinos, to name just a few large ones.
Wikipedia also lists some of the Applications of carbon dioxide.
- Precursor To Chemicals – Carbon dioxide can be one of the base chemicals used to make other important chemicals like urea and methanol.
- Foods – Carbon dioxide has applications in the food industry.
- Beverages – Carbon dioxide is the fizz in fizzy drinks.
- Winemaking – Carbon dioxide has specialist uses in winemaking.
- Stunning Animals – Carbon dioxide can be used to ‘stun’ animals before slaughter.
- Inert Gas – carbon dioxide has several uses, as it is an inert gas.
- Fire Extinguisher – Carbon dioxide is regularly used in fire extinguishers and fire protection systems.
- Bio Transformation Into Fuel – It has been proposed to convert carbon dioxide from power stations into biodiesel using a route based on algae.
- Refrigerant – Carbon dioxide can be used as a refrigerant. It was used before CFCs were developed and I know of a large Victorian refrigeration system on a farm in Suffolk, used on a store for apples, that still is in regular use that uses carbon dioxide.
- Dry Ice – The solid form of carbon dioxide has lots of applications, where cooling is needed.
Other important applications are under development.
- Agriculture – Carbon dioxide is piped to greenhouses to promote growth of crops. It is also used at higher concentrations to eliminate pests.
- Low Carbon Building Products – Companies like Mineral Carbonation International are developing ways of creating building products from carbon dioxide.
- Synthetic Rubber – Research is ongoing to create replacements for synthetic rubber.
I can only assume, that the demand for gaseous carbon dioxide will increase, as scientists and engineers get more innovative about using the gas.
Solving A Shortage Of Carbon Dioxide
At the present time, there is shortage of carbon dioxide, that I wrote about in Food Shortages Looming After Factory Closures Hit Production.
In the related post, I said this.
Perhaps we should fit carbon capture to a handy gas-fired power station, like SSE are planning to do at Keadby and use this carbon dioxide.
Consider.
- The Keadby complex of gas-fired power stations is close to a lot of depleted gas fields, some of which are in Lincolnshire and some are off-shore.
- Some gas fields are already being used to store natural gas imported from Norway.
- SSE plan to fit the later power stations with carbon capture.
I talk about SSE’s plans in Energy In North-East Lincolnshire.
If SSE were to build four large gas-fired power stations at Keadby, I calculated that they would produce 5.4 million tonnes of carbon dioxide per year.
It could be used or stored in depleted gas fields according to demand.
But the complex at Keadby would not release any carbon emissions.
Could Carbon Capture Be A Nice Little Earner?
If demand for carbon dioxide continues to rise, I could see power companies installing carbon capture on gas-fired power stations to generate an extra income stream.
Incidentally, there are 55 operational gas-fired power stations in the UK, that can generate a total of 30 GW, which are owned by perhaps ten different companies.
Development of carbon capture systems could be helped by Government subsidy.
Conclusion
I have long forgotten all the calculations I did with gases, but I do know that when one molecule of methane combusts it produces two molecules of water and one of carbon dioxide.
So I am fairly convinced that if you took X cubic kilometres of natural gas out of a gas field, after combustion there wouldn’t be anything like as much volume of carbon dioxide to put back, specially if a proportion could be used profitably in other processes.
If we are going to use gas to generate zero-carbon power, we probably need to do it with gas fields under our control either onshore or in the seas around our coasts. This is because the depleted gas fields can be used to store the carbon.
Gas-fired power stations with carbon capture supporting industries that need supplies of carbon dioxide will become a large part of our energy economy.
Food Shortages Looming After Factory Closures Hit Production
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
Acute food shortages were feared last night after high gas prices forced most of Britain’s commercial production of carbon dioxide to shut down.
In some ways, this is rather ironic, when on the one hand we are trying to stop the emission of carbon dioxide and on the other we haven’t got enough for important uses in the food industry.
Perhaps we should fit carbon capture to a handy gas-fired power station, like SSE are planning to do at Keadby and use this carbon dioxide.
If the shortage continues, there’ll be no dry ice for the pantomimes this Christmas.
FLXdrive ‘Electrifies’ Pittsburgh
The title of this post, is the same as that of this article on Railway Age.
The article describes Wabtec’s FLXdrive locomotive, as “the world’s first 100% battery, heavy-haul locomotive”
It is well worth a read, as it describes some of the design philosophy.
In addition, this page on the Wabtec web site gives some details of the locomotive.
It is powered by lithium-ion batteries.
- There are around 20,000 battery cells
- The batteries have their own air-conditioning
- There is a sophisticated battery-management system.
- The total battery size is 2.4 MWh
- Power output is 4400 HP or 3.24 MW
- Locomotive will run for 30-40 minutes at full power.
- The locomotive has regenerative braking.
- Operating speed is 75 mph
Note that running at 75 mph for 40 minutes would cover fifty miles.
The Railway age article has this paragraph, which describes a partnership between Carnegie-Mellon University (CMU), Genesee & Wyoming and Wabtec to create the Freight Rail Innovation Institute.
CMU, Genesee & Wyoming and Wabtec also hope to create the Freight Rail Innovation Institute, described as “the first-of-its-kind effort to create zero-emission locomotives, develop technology that increases freight rail utilization and improve safety by 50%, and create 250,000 jobs by 2030.” G&W’s Buffalo & Pittsburgh Railroad will pilot technologies developed by the Freight Rail Innovation Institute, including a zero-emissions battery and hydrogen-powered train that is planned for revenue operation on 200 miles of track between Pittsburgh and Buffalo, N.Y. within the next three years.
Note.
- The paragraph is very much a mission statement.
- Genesee & Wyoming are the parent of Freightliner in the UK, who are developing a dual-fuel locomotive, that I wrote about in Freightliner Secures Government Funding For Dual-Fuel Project.
It strikes me CMU, Genesee & Wyoming and Wabtec are on the right track.
Denmark Hill Station – 4th September 2021
The article on Rail Technology Magazine is entitled Denmark Hill Station First To Use Innovative Solar Technology In Europe.
The first two paragraphs describe the technology.
Denmark Hill station has become the first train station in Europe to have BIPVco’s Flextron thin film technology installed, on top of other upgrades, following a £7.5m extension.
The sophisticated and flexible solar panels are different from traditional ‘glass like’ panels, requiring no additional weight support, and will be used across other stations going forward.
Note.
- In the application of the technology at Denmark Hill station, a surplus of electricity is returned to the grid.
- BIPVco is a company based in South Wales, that evolved from research by Tata Steel and Swansea University, with the backing of the Welsh Government.
- The panels are lightweight, flexible, durable and self-cleaning.
Many years ago, I put up a barn based on timber beams, which had a sheet steel roof. These panels would be ideal for many agricultural buildings, like the one I commissioned.
These are pictures I took at Denmark Hill station, this morning.
Note.
- The original station was designed by Charles Henry Driver.
- The new entrance displays a high degree of craftsmanship, especially in the brickwork.
- The coffee and gluten-free cake I had in FCB Coffee were excellent.
- The station has its own pub; The Phoenix.
According to Network Rail, it has already been nominated for two architectural awards.
Namibia Is Building A Reputation For The Cheapest Green Hydrogen
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This paragraph explains the deal that Germany and Namibia have done.
Germany, the largest economy in Europe, has just closed a partnership with Namibia, for a supply of the cheapest green hydrogen. The Southern African country is aiming to produce its H2, made with renewable energy, for prices as low as $1.8/kg. The European nation intends to import massive volumes of what it believes will be the most affordable renewable H2 in the world. It has signed a deal with Namibia that steps up the worldwide scramble to secure the best options for H2 supply connected with substantial renewable installations.
Note.
- Namibia has the ability to produce large amounts of solar and wind energy.
- I suspect the hydrogen will be converted to liquid ammonia for shipment to Germany.
The Gremans are building a large hydrogen terminal at Wilhelmshaven, which I wrote about in Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.
Although, Namibia has now been an independent country since 1990, from 1884 to 1915 it was the German colony of German South West Africa.
Hopefully, this deal will work out to the benefit of both Germany and Namibia.
Velocys’ Fischer–Tropsch Tech Picked For E-fuels Project In Japan
The title of this post is the same as that of this article on Renewables Now.
Fischer–Tropsch technology has a chequered history, as it has been used by regimes like Nazi Germany and South Africa under apartheid to create the fuel they need.
But now Oxford University spin-out company; Velocys have improved the process, so that it can turn rubbish destined for landfill into sustainable aviation fuel.
This is the last paragraph from the article.
The developer says its FT reactor can enable the production of SAF from household waste and woody biomass. The end product is a high-quality version of existing fuels, requiring no changes to engines or infrastructure, Velocys says on its website.
This is surely a viable alternative to keep airlines flying, until hydrogen-powered planes are developed.
Langthwaite Reservoir
This site is the second application for United Utilities of floatovoltaics, where solar panels are floated on a reservoir.
This page on the Seaflex web site gives details of the project. This paragraph describes the application of the solar panels.
The 1 MW plant features approximately 3,700 pontoon modules and 3,520 solar panels, and the power generated will be used to run the neighbouring Lancaster water treatment works, which supplies water to 152,000 people across Lancaster, Morecambe and Heysham.
There are links to other floatovoltaic projects on this page.
One project at Alto Rabagao in Portugal tested the design in extreme environmental conditions.
Seaflex appear to be a Swedish company started by an inventor of a rubber mooring system.
The Immense Potential Of Solar Panels Floating On Dams
The title of this post, is the same as that of this article on the Anthropocene.
The article reviews the practice of floating solar panels on ponds, lakes and reservoirs.
I like the practice, as the two technologies are compatible.
- The panels reduce evaporation and help to curb algae growth.
- Floating panels are cooled by the environment and more efficient.
- Solar and hydro power can share electricity transmission systems.
But best of all. they use land twice.
The article claims that as much as forty percent of the world’s power can be generated this way.
The article is certainly an interesting read.
Record Levels Of Lithium In Geothermal Water At United Downs Project
The title of this post, is the same as that of this article on Think Geoenergy.
This paragraph explains it all.
Geothermal Engineering Ltd (GEL), the company behind the UK’s first deep geothermal electricity power plant, is today announcing record levels of lithium in its geothermal waters. Recent, third party tests have revealed that there are more than 250 milligrams per litre (‘mg/L’) in the fluid which is the highest concentration ever discovered in geothermal fluids anywhere in the world.
The article also says.
- The magnesium levels are low, which eases processing.
- Up to four thousand tonnes of lithium could be produced per year locally.
The article is certainly worth a read.
