Brown Seaweed Could Remove 550 Million Tons Of Carbon

The title of this post, is the same as that of this article on the Carbon Herald.

This may seem like a story that has arrived a few months early.

But the report does come from the respect Max Planck Institute for Marine Microbiology.

The research is detailed on this page on their web site, which is entitled Slime For The Cli­mate, De­livered By Brown Al­gae.

It is introduced by this sub-heading.

In form of fuc­oidan, brown al­gae could re­move up to 550 mil­lion tons of car­bon di­ox­ide from the at­mo­sphere every year.

Which is followed by this paragraph.

Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers at the Max Planck Institute for Marine Microbiology in Bremen now show. They reveal that the algal mucus called fucoidan is particularly responsible for this carbon removal and estimate that brown algae could thus remove up to 550 million tons of carbon dioxide from the air every year – almost the amount of Germany’s entire annual greenhouse gas emissions.

Note that fucoidan has a Wikipedia entry.

The page says this about brown algae.

Brown al­gae are true won­der plants when it comes to ab­sorb­ing car­bon di­ox­ide from the air.

It does seem to me that the Germans are on to something.

Neptune Energy, Ørsted And Goal7 Explore Powering Integrated Energy Hubs With Offshore Wind

The title of this post, is the same as that of this press release from Neptune Energy.

These four paragraphs outline the agreement.

Neptune Energy today announced it has signed a Memorandum of Understanding with Ørsted and Goal7 to explore powering new integrated energy hubs in the UK North Sea with offshore wind-generated electricity.

Integrated energy hubs have the potential to combine multiple energy systems, including existing oil and gas production assets, carbon storage and hydrogen production facilities. They could extend the life of producing fields and support the economic case for electrification with renewable energy, to keep carbon emissions low.

The agreement will see the companies examine the potential to supply renewable electricity from Ørsted’s Hornsea offshore windfarm projects to power future Neptune-operated hubs in the UK North Sea.

Goal7 will provide project management support and technical input.

Note.

  1. Neptune Energy has three oil and gas fields in the UK North Sea; Cygnus (operational), Isabella (exploration) and Seagull (development)
  2. Gas from Cygnus comes ashore at the Bacton Gas Terminal.
  3. Ørsted owns the Hornsea wind farm, which when fully developed will have a capacity of around 6.5 GW.
  4. Cygnus and Hornsea could be not much further than 50 km apart.
  5. Seagull and Isabella are further to the North and East of Aberdeen.
  6. Ørsted has an interest in the Broadshore wind farm, which was numbered 8 in the ScotWind Leasing round.

These are my thoughts.

The Cygnus Gas Field And The Hornsea Wind Farm

This could be like one of those stories where boy meets the girl next door and they hit it off from the first day.

This page on the Neptune web site says this about the Cygnus gas field.

The biggest natural gas discovery in the southern North Sea in over 30 years is now the largest single producing gas field in the UK, typically exporting over 250 million standard cubic feet of gas daily. Cygnus contributes six per cent of UK gas demand, supplying energy to the equivalent of 1.5 million UK homes. It has a field life of over 20 years.

Two drilling centres target ten wells. Cygnus Alpha consists of three bridge-linked platforms: a wellhead drilling centre, a processing/utilities unit and living quarters/central control room. Cygnus Bravo, an unmanned satellite platform, is approximately seven kilometres northwest of Cygnus Alpha.

In 2022, we plan to drill two new production wells at Cygnus, with the first of these expected to come onstream in 4Q. The second well is due to be drilled in the fourth quarter and is expected onstream in the first quarter of 2023, with both wells helping to maintain production from the field and offset natural decline.

Gas is exported via a 55 km pipeline. Cygnus connects via the Esmond Transmission System (ETS) pipeline to the gas-treatment terminal at Bacton, Norfolk. Neptune Energy has a 25% minority interest in ETS.

Note.

  1. Cygnus with a twenty year life could be one of the ways that we bridge the gap until we have the two Cs (Hinckley Point and Sizewell) and a few tens of offshore wind gigawatts online.
  2. The two extra wells at Cygnus will help bridge the gap.
  3. The gas field has a pipeline to Bacton.

So what can the gas field and the wind farm, do for each other?

Hornsea Can Supply The Power Needs Of Cygnus

Typically, ten percent of the gas extracted from the wells connected to a gas platform, will be converted into electricity using one or more gas-turbine engines; which will then be used to power the platform.

So, if electricity from the Hornsea wind farm, is used to power the platform, there are two benefits.

  • More gas will be sent through the pipeline to Bacton.
  • Less carbon dioxide will be emitted in recovering the gas.

Effectively, electricity has been turned into gas.

Electricity Can Be Stored On The Sea-Bed

The Hornsea One wind farm has an area in the order of 150 square miles and it is only one wind farm of four, that make up the Hornsea wind farm.

I would argue that there is plenty of space between the turbines and the wells of the Cygnus gas field to install some form of zero-carbon underwater battery to store electricity.

But does this technology exist?

Not yet! But in UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind, I described a technique called Marine Pumped Hydro, which is being developed by the STORE Consortium.

  • Energy is stored as pressurised water in 3D-printed hollow concrete spheres fitted with a hydraulic turbine and pump.
  • The spheres sit on the sea-bed.
  • This page on the STORE Consortium web site, describes the technology in detail.
  • The technology is has all been used before, but not together.

I think it is excellent technology and the UK government has backed it with £150,000 of taxpayers’ money.

I also believe that Marine Pumped Hydro or something like it, could be the solution to the intermittency of wind farms.

Excess Electricity Can Be Converted Into Hydrogen

Any spare electricity from the wind farm can drive an electrolyser to convert it into hydrogen.

The electrolyser could be mounted on one of the Cygnus platforms, or it could even float.

The hydrogen produced would be blended with the gas and sent to Bacton.

Carbon Dioxide Can Be Stored In The Depleted Cygnus Gas Field

As the gas field empties of natural gas, the gas pipes to the Cygnus gas field can be reversed and used to bring carbon dioxide to the gas field to be stored.

The Cygnus gas field has gone full circle from providing gas to storing the same amount of carbon that the gas has produced in its use.

These are two paragraphs from the press release.

Neptune Energy’s Director of New Energy, Pierre Girard, said: “The development of integrated energy hubs is an important part of Neptune’s strategy to store more carbon than is emitted from our operations and the use of our sold products by 2030.

“Neptune has submitted three applications under the recent Carbon Dioxide Appraisal and Storage Licensing Round, and securing the licences would enable us to develop future proposals for integrated energy hubs in the UK North Sea.

I can envisage a large gas-fired power-station with carbon capture being built in Norfolk, which will do the following.

  • Take a supply of natural gas from the Cygnus gas field via the Bacton gas terminal.
  • Convert the hydrogen in the gas into electricity.
  • Convert the carbon in the gas into carbon dioxide.
  • Store the carbon dioxide in the Cygnus gas field via Bacton.
  • I also suspect, that if a Norfolk farmer, manufacturer or entrepreneur has a use for thousands of tonnes of carbon dioxide, they would be welcomed with open arms.

Would the ultra-greens of this world, accept this power station as zero-carbon?

The Isabella And Seagull Gas Fields And The Broadshore Wind Farm

Could a similar set of projects be applied to the Isabella and Seagull gas fields, using the Broadshore wind farm?

I don’t see why not and they could work with the Peterhead power stations.

Landmark CCS Project In Humber Becomes UK’s First To Gain Planning Consent

The title of this post, is the same as that of this news item on the SSE web site.

This is the first paragraph.

SSE Thermal and Equinor’s Keadby 3 Carbon Capture Power Station in the Humber has become the first power CCS project in the UK to receive planning permission.

Note.

  1. This will be one of four power stations at Keadby with Keadby 1, Keadby 2 and Keadby Hydrogen Power Station.
  2. Keadby 3 will have a capacity of 910 MW.
  3. It will capture up to 1,500,000 tonnes of carbon per year.
  4. It could be operational as early as 2027.

The news item, also says this about SSE’s other power stations and hydrogen storage.

SSE Thermal and Equinor are also collaborating on Peterhead Carbon Capture Power Station in the north-east of Scotland. In addition, they are developing Keadby Hydrogen Power Station, which could be the world’s first large-scale 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could provide vital storage to balance intermittent supply and demand.

This all fits nicely with the proposed strategy I wrote about in Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero.

I think we can expect more new gas-fired power stations with carbon capture to be built by SSE.

Green Groups Furious As New Coalmine In Cumbria Is Approved

The title of this post, is the same as that of this article on The Times.

These two paragraphs outline the story.

Michael Gove has approved the first deep coalmine in 30 years, despite calls from environmental activists and Labour to turn down the project.

The levelling-up secretary’s planning approval for the mine in Cumbria comes after two years of opposition. Critics said that it would increase emissions and 85 per cent of the coking coal would be exported to produce steel.cumbria

In March 2019, I wrote Whitehaven Deep Coal Mine Plan Moves Step Closer, when local councillors unanimously backed the plan.

In that post, I speculated about the possibility of using the coal from Cumbria with the HIsarna ironmaking process and wrote this.

In Wikipedia, there is an entry for the HIsarna ironmaking process.

This process is being developed by the Ultra-Low Carbon Dioxide Steelmaking (ULCOS) consortium, which includes Tata Steel and the Rio Tinto Group. Reduction in carbon-dioxide produced by the process compared to traditional steel-making are claimed to be as high as fifty percent.

This figure does not include carbon-capture to reduce the carbon-dioxide still further.

However, looking at descriptions of the process, I feel that applying carbon-capture to the HIsarna steelmaking process might be a lot easier, than with traditional steelmaking.

If you are producing high quality steel by a process like HIsarna, you want to make sure that you don’t add any impurities from the coal, so you have a premium product.

So is Cumbrian metallurgical coal important to the HIsarna process?

I originally heard that the coal from Whitehaven was very pure carbon and I felt as the HIsarna process uses powdered coal, there might be a connection between the two projects. Reading today in The Times article, it seems that the Cumbrian coal has some sulphur. So either the HIsarna project is dead or the Dutch have found a way to deal with the sulphur.

The HIsarna process is a continuous rather than a batch process and because of that, it should be easier to capture the carbon dioxide for use elsewhere or storage in a depleted gas field.

There’s more to come out on the reason for the approval of the project.

I shall be digging hard to see what I can find. But I do believe a steel-making process, that uses a much smaller amount of coal, not coke, could lead to a more economic way of making zero-carbon steel than using hydrogen created by electrolysis.

Carbon capture would need to be used to deal with carbon dioxide produced, but progress is being made with this technology.

Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero

The title of this post, is the same as that of this news item on the SSE web site.

This is the first paragraph.

Building more power carbon capture and storage plants (Power CCS) could significantly accelerate the UK’s plans to decarbonise the GB electricity system on route to net zero, according to new analysis commissioned by SSE.

I am not surprised, as in my time, I have built several production, storage and distribution mathematical models for products and sometimes bringing things forward has beneficial effects.

These three paragraphs summarise the findings.

The UK Government’s proposed emissions reductions from electricity for 2035 could be accelerated to 2030 by combining its 50GW offshore wind ambition with a significant step up in deployment of Power CCS. This would require 7-9GW (equivalent to 10-12 plants) of Power CCS compared to the current commitment of at least one Power CCS plant mid-decade, according to experts at LCP Delta.

Replacing unabated gas with abated Power CCS generation will deliver significant reductions in greenhouse gas emissions. The analysis suggests that adding 7-9GW Power CCS to the UK’s 2030 offshore wind ambition will save an additional 18 million tonnes of CO2 by 2040, by preventing carbon emissions during periods when the sun isn’t shining, and the wind isn’t blowing.

Gas consumption for electricity generation would not significantly increase, given the 7-9GW Power CCS would displace older and less efficient unabated gas power stations already operating and reduce importing unabated gas generation from abroad via the interconnectors. Importantly, Power CCS can provide a safety net to capture emissions from any gas required to keep the lights on in the event of delays to the roll out of renewables or nuclear.

The report is by LCP Delta, who are consultants based in Edinburgh.

The report says this about the transition to hydrogen.

Power CCS also presents significant opportunities to kickstart, then transition to, a hydrogen economy, benefitting from the synergies between CCS and hydrogen, including proximity to large-scale renewable generation and gas storage facilities which can support the production of both electrolytic and CCS-enabled hydrogen.

And this about the reduction in carbon emissions.

The existing renewables ambition and the accelerated Power CCS ambition are expected to save a total of 72 million tonnes of CO2 by 2040 compared to commitments in the UK’s Net Zero Strategy from October 2021.

I don’t think there’s much wrong with this analysis.

But of course the greens will trash it, as it was paid for by SSE.

I have a few thoughts.

Carbon Capture And Use

I believe we will see a great increase in carbon capture and use.

  • Carbon dioxide is already an ingredient to make Quorn.
  • Carbon dioxide is needed for fizzy drinks.
  • Carbon dioxide can be fed to tomatoes, salad plants, herbs and flowers in giant greenhouses.
  • Carbon dioxide can be used to make animal and pet food.
  • Carbon dioxide can be used to make building products like plasterboard and blocks.
  • Carbon dioxide can be added to concrete.
  • Carbon dioxide can be used as a refrigerant and in air-conditioning. There are one or two old Victorian systems still working.

Other uses will be developed.

Carbon Capture Will Get More Efficient

Carbon capture from power stations and boilers, that use natural gas is a relatively new process and its capture will surely get better and more efficient in the next few years.

Gas From INTOG

I explain INTOG in What Is INTOG?.

One of INTOG’s aims, is to supply electricity to the oil and gas rigs and platforms in the sea around the UK.

Currently, these rigs and platforms, use some of the gas they produce, in gas turbines to create the electricity they need.

  • I have seen reports that ten percent of the gas that comes out of the ground is used in this way.
  • Using the gas as fuel creates more carbon dioxide.

Decarbonisation of our oil and gas rigs and platforms, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.

Gas may not be carbon-neutral, but some gas is more carbon-neutral than others.

SSE’s Plans For New Thermal Power Stations

I have taken this from SSE’s news item.

SSE has deliberately chosen to remain invested in the transition of flexible thermal electricity generation due to the key role it plays in a renewables-led, net zero, electricity system and is committed to decarbonising the generation.

Together with Equinor, SSE Thermal is developing two power stations equipped with carbon capture technology. Keadby 3 Carbon Capture Power Station is based in the Humber, the UK’s most carbon-intensive industrial region, while Peterhead Carbon Capture Power Station is located in the North East of Scotland. Combined, the two stations could capture around three million tonnes of CO2 a year.

Studies have shown that Keadby and Peterhead Carbon Capture Power Stations could make a lifetime contribution of £1.2bn each to the UK economy, creating significant economic opportunity in their respective regions. Both will be vital in supporting the huge amount of renewables which will be coming on the system.

SSE Thermal and Equinor are also collaborating on Keadby Hydrogen Power Station, which could be one of the world’s first 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could be one of the world’s largest hydrogen storage facilities.

Note.

  1. SSE appear to think that gas-fired power stations with carbon capture are an ideal backup to renewables.
  2. If gas is available and it can be used to generate electricity without emitting any carbon dioxide, then why not?
  3. Hydrogen is coming.

Things will get better.

Is A Virtuous Circle Developing?

Consider.

  • Spare wind electricity is turned into hydrogen using an electrolyser or perhaps some world-changing electro-chemical process.
  • The hydrogen is stored in Aldbrough Hydrogen Storage.
  • When the wind isn’t blowing, hydrogen is used to backup the wind in Keadby Hydrogen power station.
  • The other Keadby power stations can also kick in using natural gas. The carbon dioxide that they produce, would be captured for storage or use.
  • Other users, who need to decarbonise, can be supplied with hydrogen from Aldbrough.

Note.

  1. Gas turbines are throttleable, so if National Grid wants 600 MW to balance the grid, they can supply it.
  2. As time progresses, some of the gas-fired power stations at Keadby could be converted to hydrogen.
  3. Rough gas storage is not far away and could either store natural gas or hydrogen.
  4. Hydrogen might be imported by tanker from places like Africa and Australia, depending on price.

Humberside will be levelling up and leading the decarbonisation of the UK.

If you have an energy-hungry business, you should seriously look at moving to Humberside.

Hydrogen Fuel Pioneer Wins £247k Funding For Carbon Capture Tech

The title of this post, is the same as that of this article on gasworld.

This is the introductory paragraph.

UK-based waste-to-hydrogen specialist Compact Syngas Solutions (CSS) has won £246,568 from the Hydrogen BECCS (bioenergy with carbon capture and storage) Innovation Programme.

I first wrote about Compact Syngas Solutions, in Welsh Firm Wins £300K BEIS Grant To Advance Hydrogen Fuel Tech.

Compact Syngas Solutions appear to be developing a process to turn waste, that would otherwise go to landfill, into green hydrogen.

  • The first stage turns the waste into syngas using gasification.
  • This process produces carbon dioxide, which must be captured.
  • Compact Syngas Solutions seem to have found a chemical mechanism, that uses water to capture this carbon dioxide instead of ammonia-derived amines.

The last two paragraphs of the article state Compact Syngas Solutions’s plans.

Intended to be portable, CSS plans to develop ten Micro H2 hubs complete with four gasifiers.

Capable of producing 60kg of hydrogen and capturing 3.1kg of CO2 per day, the technology could contribute to full-scale Waste-to-Syngas-Liquid-Fuel facilities, leading to a 50,100 tonne CO2 capture capacity in the UK.

I feel, that if this technology can be made to work at scale, then Compact Syngas Solutions will have a viable way to make green hydrogen.

Significant Step Forward For Keadby 3 Carbon Capture Power Station

The title of this post, is the same as that of this press release from SSE.

These three paragraphs outline the project.

A landmark project in the Humber which could become the UK’s first power station equipped with carbon capture technology has taken a major leap forward following an announcement by the UK Government today.

Keadby 3 Carbon Capture Power Station, which is being jointly developed by SSE Thermal and Equinor, has been selected to be taken forward to the due diligence stage by the Department for Business, Energy and Industry Strategy (BEIS) as part of its Cluster Sequencing Process.

This process will give the project the opportunity to receive government support, allowing it to deploy cutting edge carbon capture technology, and to connect to the shared CO2 pipelines being developed through the East Coast Cluster, with its emissions safely stored under the Southern North Sea. The common infrastructure will also supply low-carbon hydrogen to potential users across the region.

The press release also says this about the power station.

  • Keadby 3 power station could have a generating capacity of up to 910MW.
  • It could be operational by 2027.
  • It would capture up to one and a half million tonnes of CO2 a year.

It would provide low-carbon, flexible power to back-up renewable generation.

The H2H Saltend Project

The press release also says this about the H2H Saltend project.

Equinor’s H2H Saltend project, the ‘kick-starter’ for the wider Zero Carbon Humber ambition, has also been taken to the next stage of the process by BEIS. The planned hydrogen production facility could provide a hydrogen supply to Triton Power’s Saltend Power Station as well as other local industrial users. In June, SSE Thermal and Equinor entered into an agreement to acquire the Triton Power portfolio.

I wrote about H2H Saltend and the acquisition of Triton Power in SSE Thermal And Equinor To Acquire Triton Power In Acceleration Of Low-Carbon Ambitions.

In the related post, I added up all the power stations and wind farms, that are owned by SSE Thermal and it came to a massive 9.1 GW, which should all be available by 2027.

Collaboration Between SSE Thermal And Equinor

The press release also says this about collaboration between SSE Thermal and Equinor.

The two companies are also collaborating on major hydrogen projects in the Humber. Keadby Hydrogen Power Station could be one of the world’s first 100% hydrogen-fuelled power stations, while Aldbrough Hydrogen Storage could be one of the world’s largest hydrogen storage facilities. In addition, they are developing Peterhead Carbon Capture Power Station in Aberdeenshire, which would be a major contributor to decarbonising the Scottish Cluster.

This collaboration doesn’t lack ambition.

I also think, that there will expansion of their ambitions.

Horticulture

Lincolnshire is about horticulture and it is a generally flat county, which makes it ideal for greenhouses.

I wouldn’t be surprised to see a large acreage of greenhouses built close to the Humber carbon dioxide system, so that flowers, salad vegetables, soft fruit, tomatoes and other plants can be grown to absorb the carbon dioxide.

It should also be noted that one of the ingredients of Quorn is carbon dioxide from a fertiliser plant, that also feeds a large tomato greenhouse.

We would have our carbon dioxide and eat it.

Other Uses Of Carbon Dioxide

Storing carbon dioxide in depleted gas fields in the North Sea will probably work, but it’s a bit like putting your rubbish in the shed.

Eventually, you run out of space.

The idea I like comes from an Australian company called Mineral Carbonation International.

We would have our carbon dioxide and live in it.

I also think other major uses will be developed.

A Large Battery

There is the hydrogen storage at Aldbrough, but that is indirect energy storage.

There needs to be a large battery to smooth everything out.

In Highview Power’s Second Commercial System In Yorkshire, I talk about Highview Power’s proposal for a 200MW/2.5GWh CRYOBattery.

This technology would be ideal, as would several other technologies.

Conclusion

Humberside will get a giant zero-carbon power station.

New Proton Ceramic Reactor Stack For Highly Efficient Hydrogen Production And Carbon Capture In A Single Step

The title of this post, is the same as that of this article on Green Car Congress.

This is the opening paragraph.

A team of researchers from CoorsTek Membrane Sciences and SINTEF in Norway, and Universitat Politècnica de València in Spain, has demonstrated a 36-cell well-balanced proton ceramic reactor stack enabled by a new interconnect that achieves complete conversion of methane with more than 99% recovery to pressurized hydrogen, leaving a concentrated stream of carbon dioxide. The team has also demonstrated that the process can be scaled up for commercial application.

A paper has been published in the journal; Science.

I find this concept interesting for a number of reasons.

  • I’ve believed for some time, that applications, that need a good supply of pure carbon dioxide will be developed. One obvious use is feeding it to plants in large greenhouses, so we can have our CO2 and eat it!
  • 99 % is a very high efficiency.
  • Ammonia, natural gas or biogas can be used as a feedstock.

Coors were an Artemis user for project management and I had an enjoyable few days Golden, Colorado and at the Coors brewery, sometime in the 1980s.

  • It was then that I first heard of CoorsTek, who used to make ceramics for the US defence industry.
  • In those days, the beer was made to German brewing rules and was unpasteurised.
  • The beer had to be delivered to customers within a certain time, so long distance deliveries used trains.
  • Coors Brewing Company has since merged with Molson, but CoorsTek appears to be still owned by the Coors family.
  • I had taken a few small bottles of Adnams Broadside with me and one of their managers analysed one before drinking the rest of the bottle. He informed me that it was a felony to be in possession of such a strong beer in Colorado.

Coors were and probably still are in some ways not your average brewing company.

Coors News Item On Proton Ceramic Membranes For Hydrogen Production

This page on the CoorsTek web site, which is entitled Proton Ceramic Membranes For Hydrogen Production Published In ‘Science’, gives more details.

Conclusion

This technology could be massive.

Air Products Partners Up On Hydrogen Production In The UK

The title of this post, is the same as that of this article on Upstream.

These three paragraphs explain the project.

Air Products has joined with power generator VPI to push forward a hydrogen hub on the south bank of the Humber Estuary in the UK, primarily meant to decarbonise VPI’s power production in Immingham.

The companies said they will develop an 800-megawatt production facility called the Humber Hydrogen Hub (H3) that would include carbon capture and storage and aim to capture up to 2 million tonnes per annum of carbon dioxide.

Hydrogen produced at the facility will first substitute fuel for VPI’s existing third gas turbine power train.

Note.

  1. VPI is a UK-based power company, providing energy to the National Grid.
  2. Immingham Power station is currently a 730 MW gas-fired power station, which is being expanded to 1240 MW.
  3. It looks like that expansion will use hydrogen.

It is all part of HumberZero.

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.

  1. It is a physical rather than a chemical process.
  2. 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.

  1. The trial will last for two months and will be hosted within Drax’s BECCS incubation hub at its North Yorkshire Power Station.
  2. 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.
