The Anonymous Widower

The Edmonton Incinerator

Although it is officially known these days as the Edmonton EcoPark, as a North Londoner, I will always know it as the Edmonton Incinerator.

I took these pictures with my drone.

These are a few facts from Wikipedia about the waste-to-energy plant.

  • It was commissioned by the Greater London Council in 1971.
  • It burns waste from the seven North-East London boroughs.
  • It generates 55 MW of electricity.

It certainly dominates the landscape alongside the North Circular Road.

But.

It is probably not amongst the greenest of incinerators.

It is probably very much a design of the 1960s.

It is approaching fifty years old.

But it appears that things could be improving.

  • There is a large composting and recycling facility being built on the site on the site.
  • Plans exist to bring in the rubbish by barge.

This Google Map shows the site.

Note.

  1. The North Circular Road runs across the bottom of the map.
  2. All of the roads obliterated the famous Cooks Ferry Inn, where I saw the Animals play in the 1960s.
  3. The River Lee Navigation runs past the incinerator.
  4. Pymme’s Brook runs on the other side.

It looks from the map, that another reservoir is being built to the East of the canal.

The Guy Who Built The Edmonton Incinerator

I used to work with the guy, who was one of those in charge of the building of the incinerator, who when I met him, was head of the Greater London Council’s Construction Branch, who were using my project management software.

I can’t remember Mr. Samuels first name, even if I ever knew it.

  • He was an Austrian Jew, who had trained as an engineer, who arrived in the UK sometime in the 1930s.
  • He taught himself English in six weeks and got a job at Lucas.
  • At the start of World War II, he volunteered and joined the Royal Engineers.
  • He spent the whole war in bomb disposal.
  • After the war he became an observer at the Nuremberg Trials.

After all he’d been through, he told me, the worst time of his life, was those years in the early seventies when I knew him, as his wife was dying of cancer.

But he taught me a lot about project management and the real horror of war.

He never told me, how many of his relatives survived the Nazis.

What Will Happen To The Edmonton Incinerator?

This year it will be fifty years since the Edmonton Incinerator was commissioned. It must be coming to the end of its life.

I can’t find any plans, but endless groups, who want it closed rather than rebuilt.

This article in the Hackney Gazette, which is entitled Campaigners Urge North London Incinerator Bidders To Pull Out, is typical.

I am very pro recycling, but then others aren’t as these pictures show.

So if some won’t recycle properly, it will all have to go to landfill.

An Odd Tale About Recycling

I applied to be a member of the Independent Monitoring Board of a prison near, where I used to live.

I had a very interesting tour of the prison, where I met several of the inmates.

One thing surprised me.

The prison had a very comprehensive internal recycling system, whereby everything was fully sorted.

One course of training, that was offered to prisoners was how to sort and process all of the rubbish. According to the guy running the course, it was one of the most popular in the prison.

Possibly, because I was told, it prepared prisoners for a job, where there were lots of vacancies.

I wonder if the new £100million recycling centre at Edmonton will use labour trained in the Prison Service?

Beeching Reversal – Reopening Harston Station

This is one of the Round 3 bids of Beeching Reversal projects that the Government and Network Rail are proposing to reverse some of the Beeching cuts.

Harston is a Cambridgeshire village, which is shown in this Google Map.

Note.

  1. The A10 winding its way North and South through the village.
  2. Cambridge is five miles to the North.
  3. The triangular road junction in the middle of the village with Station Road leading off to the South East.
  4. The Cambridge Line crosses the South-East corner of the map, at a right angle to Station Road.

This Google Map shows the former station site at an enlarged scale..

Note.

  1. There is plenty of space.
  2. There is a level crossing.
  3. The railway is double-track.

There’s even a Harston History page for the station, so if the architect’s decide to go retro, they can visit it for design inspiration.

My initial thoughts are that compared to some of the proposals for Beeching Reversal this one is practical and not over ambitious.

These are some of my thoughts.

Car Parking

Currently, there are the following stations between Cambridge and Hitchin.

Note.

Only Royston station has more than minimal parking provision.

The addition of Harston and Cambridge South stations will probably mean, that a lot of thought will be given to parking at all the stations between Cambridge and Hitchin.

Cambridge South like Cambridge North will probably have extensive parking to also serve Addenbrooke’s Hospital and Cambridge Bio-Medical Campus.

Whittlesford Parkway station on the line between Cambridge and Liverpool Street has very adequate parking provision.

I wouldn’t be surprised to see Harston station having a couple of hundred parking spaces.

East West Railway

In Looking At The East West Railway Between Bedford And Cambridge, I looked at the route of the East West Railway as it approaches Cambridge.

I very much doubt that this new railway will go through Harston station.

But Harston station will beef up the capacity on the Cambridge Line to bring more workers to one of the science and engineering capitals of the world.

Cambridgeshire Autonomous Metro

There are also plans for the Cambridgeshire Autonomous Metro.

This map shows the proposed layout of the Cambridgeshire Autonomous Metro.

Note that the green section will be in tunnel.

I doubt that the Cambridgeshire Autonomous Metro will run to Harston, as it most likely will run on rubber-tyred wheels and probably wouldn’t mix well with heavy rail.

Train Service

Currently, the current trains run through the station in the Off Peak.

  • Thameslink – 2 tph – Cambridge and Brighton
  • Thameslink – 2 tph – Cambridge and King’s Cross
  • Great Northern – 1 tph – King’s Cross and Ely
  • Great Northern – 1 tph – King’s Cross and King’s Lynn

Note.

  1. tph is an abbreviation for trains per hour.
  2. All trains are fast services, except for the Cambridge and King’s Cross service, which stops at all stations.
  3. When Cambridge South station opens, I suspect nearly all services will stop at that station.
  4. The Great Northern services also stop at Cambridge North station.
  5. In Call For ETCS On King’s Lynn Route, I talked of the possibility of running 125 mph trains on Great Northern services between King’s Cross, Cambridge, Cambridge North, Ely and King’s Lynn.

I suspect that it will be likely only the Thameslink stopping train will call at Harston station, just as it is the only service that calls at Foxton, Shepreth and Meldreth stations.

  • But is two tph enough for a Park-and-Ride station?
  • Whittlesford Parkway station already has three tph to and from Cambridge.
  • I suspect there will be a second Stansted and Cambridge service which mean Whittlesford Parkway station gets four tph to Cambridge,

I suspect Hartston station needs four tph to give a Turn-Up-And-Go service.

Barrington Quarry And Landfill

This Google map shows the location of the Barrington Quarry and Landfill, with respect to Harston.

Note.

  1. Barrington Quarry and Landfill is in the North-West corner of the map.
  2. Harston is in the North-East corner of the map.
  3. The A10 road runs South-West from Harston to Foxton station, where there is a level crossing, where the Cambridge Line crosses the road.
  4. Foxton station has a freight-only line linking it to the quarry.

This second Google Map shows Foxton station in detail.

Note the rail line to Barrington curving away to the North West.

This document from CEMEX is entitled Barrington Quarry – Restoration Project.

It appears that the quarry will be restored and some of the land will be used for new homes.

As all the track is already in place, would it be possible to run a 2tph service between Barrington and Cambridge North station?

  • It could call at  Harston, Cambridge North and Cambridge stations.
  • Harston station would get a four tph service.
  • Cambridge gets more much-needed housing connected to the city.

It could also be run using battery-electric trains that would be charged using the electrification between Foxton and Cambridge North stations.

Conclusion

Taking everything together, it appears to me, that Harston station could improve the rail network to the South West of Cambridge.

Green Jet Fuel Plant Developers’ Ioy As World Economic Forum Backs Method As Best Aviation Solution

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

This is the first paragraph.

The World Economic Forum has backed sustainable aviation fuel as the most promising decarbonation policy for aviation, delighting the developers of a £350 million refinery on the Humber.

I bet Velocys are delighted.

I also think, that, the biodiesel, that they can produce, is a short term solution to the decarbonisation of rail freight and the heaviest vehicles powered by diesel.

It’s so much better than throwing the rubbish into landfill.

Microwaves Could Turn Plastic Waste Into Hydrogen Fuel

This headline from this article in The Times could be the headline of the day!

Although thinking about it, it wouldn’t be a good idea to put all your plastic waste in the microwave and switch it on. It might catch fire or even worse create lots of hydrogen in your kitchen, which could be followed by a mini-Hindenburg disaster in the kitchen.

These are the introductory paragraphs.

From the yellowed bottles in landfill to the jellyfish-like bags clogging the oceans, plastics pollution is an apparently intractable problem.

Yet, chemists lament, it shouldn’t be. Within this waste there is something extremely useful, if only we could access it: hydrogen. Now a British team of scientists believes it has found a way to get at it, and do so cheaply, thanks to tiny particles of iron and microwaves.

If their system works at scale they hope it could be a way of cheaply converting useless plastic into hydrogen fuel and carbon.

Don’t we all want to believe that this impossible dream could come true?

Some Background Information

Some of the things I talk  about will be technical, so I will have a bit of a preamble.

Hydrogen; Handling And Uses

Because of pre-World War Two airships, which tended to catch fire and/or crash, hydrogen has a bad reputation.

I used to work as an instrument engineer in a hydrogen plant around 1970. To the best of my knowledge the plant I worked  in is still producing  hydrogen in the same large building at Runcorn.

Hydrogen is one of those substances, that if you handle with care, it can be one of the most useful elements in the world.

It is a fuel that burns creating a lot of energy.

The only by-product of hydrogen combustion is steam.

It is one of the feedstocks for making all types of chemicals like ethylene, fertilisers, ammonia, pharmaceuticals and a wide range of hydrocarbons.

Hydrogen is a constituent of natural gas and in my youth, it was a constituent of town gas.

Hydrogen and hydrocarbons are involved in the manufacture of a lot of plastics.

In the future, hydrogen will have even more uses like making steel and cement, and powering railway trains and locomotives, and shipping of all sizes.

Hydrocarbons

According to Wikipedia, hydrocarbons are compounds consisting entirely of atoms of hydrogen and carbon.

In a kitchen, there are several hydrocarbons.

  • If you cook by gas, you will probably be burning natural gas, which is mainly methane, which is a hydrocarbon
  • Some might use propane on a barbecue, which is another hydrocarbon.
  • I suspect you have some polythene or polyethylene, to use the correct name, in your kitchen. This common plastic is chains of ethylene molecules. Ethylene is another hydrocarbon.
  • There will also be some polypropylene, which as the name suggests is made from another hydrocarbon; propylene.

Hydrocarbons are everywhere

Plastics

I used to work in two ICI divisions; Mond at Runcorn and Plastics at Welwyn Garden City

  • The forerunners of ICI Mond Division invented polyethylene and when I worked at Runcorn, I shared an office, with one of the guys, who had been involved before the Second World War. in the development of polyethylene.
  • Plastics Division used to make several plastics and I was involved in various aspects of research plant design and production.

One day, I’ll post in this blog, some of the more interesting and funnier stories.

Many plastics are made by joining together long chains of their constituent molecules or monomer.

  • Ethylene is the monomer for polyethylene.
  • Propylene is the monomer for polypropylene.
  • Vinyl chloride is the monomer for polyvinylchloride or PVC.

So how are the chains of molecules built?

  • Polyethylene was made by ICI. by applying large amounts of pressure to ethylene gas in the presence of a catalyst.
  • They used to make polypropylene in large reaction vessels filled with oil, using another catalyst.

I suspect both processes use large quantities of energy.

Catalysts

catalyst is a substance which increases the rate of a chemical reaction.

Judging by the number of times, I find new catalysts being involved in chemical reactions, the following could be true.

  • There are processes, where better catalysts can improve yields in the production of useful chemicals.
  • There is a lot of catalyst research going on.

Much of this research in the UK, appears to be going on at Oxford University. And successfully to boot!

Velocys

It should be noted that Velocys was spun out of Oxford University, a few years ago.

This infographic shows their process.

This could be a route to net-zero carbon aviation and heavy haulage.

The beauty is that there would need to be little modification to existing aircraft and trucks.

Oxford University’s Magic Process

These paragraphs from The Times article explain their process.

The clue came in research on particles of iron, and what happens when they get really small. “There’s a fascinating problem,” Professor Edwards said. “You take a bit of metal, and you break it into smaller and smaller bits. At what stage does it stop behaving like a copy of the bigger bit?”

When the particle gets below a critical size, it turns out it’s no longer a metal in the standard sense. The electrical conductivity plummets, and its ability to absorb microwaves does the reverse, increasing by ten orders of magnitude.

Professor Edwards realised that this could be useful. “When you turn on the microwaves, these things become little hotspots of heat,” he said. When he put them in a mix of milled-up plastic, he found that they broke the bonds between the hydrogen and carbon, without the expense and mess of also heating up the plastic itself.

What is left is hydrogen gas, which can be used for fuel, and lumps of carbon nanotubes, which Professor Edwards hopes might be of a high enough grade to have a use as well. The next stage is to work with industry to find ways to scale it up.

It sounds rather amazing.

Going Large!

This article from The Times on Friday, is entitled Plastic To Be Saved From Landfill By Revolutionary Recycling Plants.

These are the two introductory paragraphs.

Thousands of tonnes of plastic waste will be turned into new plastic in Britain rather than dumped in landfill sites, incinerated or sent overseas under plans for four new plants that will use cutting-edge recycling technology.

Up to 130,000 tonnes of plastic a year will be chemically transformed in the facilities, which are to be built in Teesside, the West Midlands and Perth.

It all sounds like technology, that can transform our use of plastics.

Conclusion

In the years since I left Liverpool University in 1968 with a degree in Electrical and control Engineering, it has sometimes seemed to me, that chemistry has been a partly neglected science.

It now seems to be coming to the fore strongly.

Humber Highlighted As Prime Location For Sustainable Aviation Fuel Cluster

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

Points to note from the article.

  • Development of a waste-to-aviation biofuel plant on Humberside could be a £219 million annual boost to the economy and create 1500 jobs.
  • There is a pipeline to Heathrow from the Humber.
  • Velocys is backed by British Airways and Shell, and the UK government.
  • Not bad for an Oxford University spin-off of an updated process that produced diesel for the Nazis and apartheid South Africa.
  • Other potential sustainable aviation fuel clusters have been identified including Teesside, the North West, South Wales, Hampshire, St Fergus and Grangemouth.

Velocys is a share to watch!

Other Thoughts

I feel the following could happen.

  • Velocys will make a large hole in the need for landfill capacity.
  • Other old chemical and refinery processes will be updated using new catalyst technology, from universities like Oxford.

But will British Airways be accused of rubbish flights in the tabloids?

Waste-to-Hydrogen Project Set For California

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

This is the introductory paragraph.

A California company that produces renewable hydrogen has joined with a Louisiana construction group on a project to build a modular waste-to-hydrogen production facility.

These are some further points.

  • The Californian company; Ways2H, also has a project in Japan.
  • They aim to setup a pipeline of projects in 2021.
  • The California Energy Commission has said the state is short of green hydrogen.
  • The process can use paper and plastic waste or municipal solid waste.
  • They can also handle medicinal waste.
  • The systems appear to be transportable.

This paragraph is from the article.

Kindler said his company could produce “white hydrogen,” because the company’s process, which uses very high temperatures to turn waste plastics, wood, rubber and other biomass into gas and a carbon solid, can be used to sequester carbon dioxide and store it underground.

It looks to me, that if they make this system work, they will have found an alternative way to make hydrogen, by a zero-carbon method.

Conclusion

Could we see one of these plants in every local authority in the world to process all their waste into hydrogen?

I suspect in Ways2H’s plan for world domination, this is one of their objectives.

Exeter City Council Builds Its First Solar And Battery Storage Project

The title of this post, is the same as that of this article on Energy Live News.

This paragraph describes the scheme.

The plant, which had its preparatory work finished recently, will be built on an inactive landfill site and will comprise of a 1.2MW array of 3,702 solar photovoltaic (PV) modules, two battery storage containers and an electrical switch room.

I do think, this is a superb use for a old landfill site.

As I believe that some landfill sites still give off methane for many years, if this is the case, this can surely continue.

The scheme will also include a 1 MW/2 MWh battery and will be geared to providing power to a council operation’s facility and in the future to supporting an electric fleet.

This is a superb example of how to turn an unwanted toxic liability into a green asset, with several benefits.

I have not heard of something like this before, but by searching the list of solar and energy-from-waste power sites in the UK, I found a cluster around the M5 to the North of the village of Puriton.

This Google Map shows the area.

Note.

  1. The village of Puriton to the East of the Junction 23 of the M5, which is a forest of blue dots.
  2. The various solar farms showing as a blue-violet field. I can count fourteen separate fields.

In total, there are about half-a-dozen renewable energy producers in the area generating up to 25 MW of electricity.

The area to the North-East of the village with all the white dots, just above the green one, is the former Royal Ordinance Factory Bridgewater, which I’m sure solar farmers would like to get their hands on.

Would this become a modern version of swords into ploughshares?

Grant Shapps Announcement On Friday

I listened to Grant Shapps announcement on Friday, when he gave the daily COVID-19 Press Conference.

This article on the Velocys web site is entitled Government Announces Jet Zero Council And Confirms Support For Velocys Waste-To-Jet-Fuel Project.

The article shows a video of the speech and this summary paragraph.

At this afternoon’s COVID-19 press conference, Secretary of State for Transport, Grant Shapps, announced the establishment of a new Jet Zero Council and confirmed Government support for Velocys.

So who are the company with the strange name of Velocys?

This is a quote from the Velocys CEO; Henrik Wareborn.

Today’s announcement on the formation of a Jet Zero Council shows that a new era of net zero carbon flying is on a credible path, at a time when we need it more than ever. This follows news earlier today that our Altalto waste-to-jet fuel facility – the first of its kind in the UK – has received additional funding from Government and formally received planning permission, meaning it could be producing sustainable aviation fuel in commercial scale by the middle of this decade.

Is a new era of net zero carbon flying a possibility or is this a dream too far?

The AltAlto Project

Yhe project is called AltAlto and it has its own web site.

It is backed by British Airways and Shell, and uses technology from Velocys.

This description of the project is on the home page.

Altalto turns household and commercial waste into clean-burning fuels with reduced greenhouse gas emissions for air and road transport.

A page called Technology describes how it is done.

This is the initial summary.

Our process can accept a wide variety of waste, while delivering a clean product. There are very limited emissions to atmosphere from the plant except water and carbon dioxide. Components of the waste which do not get turned into fuel, such as metals and stones, are recycled; a small amount of it (less than 3%) goes to landfill.

This diagram from the Velocys web site illustrates the process.

The then goes through the stages of the process.

  • Stage 1 – Preparation – First the waste is treceived, sorted and prepared.
  • Stage 2 – Gasification – Next the solid waste is gasified; heated to a high temperature to break it down and convert it into synthesis gas or syngas (carbon monoxide and hydrogen).
  • Stage 3 – Synthesis – After cleaning, the syngas is used to synthesis hydrocarbons using the Fischer-Tropsch technology provided by Velocys.
  • Stage 4 – Finishing – These hydrocarbons are then refined into the final products; renewable jet fuel (in the form of SPK) and naphtha.

They add this final summary.

The process is fundamentally different to incineration: instead of being burnt, the carbon in the waste is converted into a fuel for use in aircraft or vehicles.

There are many clean ways of making electricity, but it is really difficult to make sustainable jet fuel – this is one of the very few economic ways of doing so. It’s therefore a far better use of household waste than incineration, creating a much more valuable and environmentally beneficial product.

Could the process be considered a sophisticated waste incineration process, where the actual incineration is performed in the turbofan engine in the aircraft or the diesel engine in the truck to provide power?

I have a few questions.

What is Fischer-Tropsch Technology?

This is the first sentence for the Wikipedia entry for the Fischer-Tropsch Process.

The Fischer-Tropsch process is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150-300 °C (302-572 °F) and pressures of one to several tens of atmospheres. The process was first developed by Franz Fischer and Hans Tropsch at the Kaiser-Wilhelm-Institut fur Kohlenforschung in Mulheim an der Ruhr, Germany, in 1925.

One of the companies involved in using the Fischer-Tropsch process is the South African company; Sasol. Wikipedia gives this summary about Sasol’s use of the process.

Another large scale implementation of Fischer-Tropsch technology is a series of plants operated by Sasol in South Africa, a country with large coal reserves, but little oil. The first commercial plant opened in 1952. Sasol uses coal and now natural gas as feedstocks and produces a variety of synthetic petroleum products, including most of the country’s diesel fuel.

The involvement with the apartheid regime in South Africa probably wasn’t the best of publicity for the process.

But have Oxford University and Velocys created a way of making net zero carbon aviation and diesel fuels?

What Is SPK?

SPK is Synthetic Paraffinic Kerosene and it is an aviation biofuel.

The Wikipedia entry for aviation biofuel has a sub-section called FT-SPK, where this is said.

The second route involves processing solid biomass using pyrolysis to produce pyrolysis oil or gasification to produce a syngas which is then processed into FT SPK (Fischer-Tropsch Synthetic Paraffinic Kerosene)

This sounds like the Velocys process.

What Are The Environmental Effects?

In the Wikipedia entry for aviation biofuel, there is a section called Environmental Effects. This is the first sentence.

A life cycle assessment by the Yale School of Forestry on jatropha, one source of potential biofuels, estimated using it could reduce greenhouse gas emissions by up to 85% if former agro-pastoral land is used, or increase emissions by up to 60% if natural woodland is converted to use. In addition, biofuels do not contain sulphur compounds and thus do not emit sulphur dioxide.

As Velocys produce their SPK from household waste, their fuel will have a different and more positive effect on greenhouse gas emissions.

This press release on the Velocys web site is entitled Plans Submitted For The First Waste To Jet Fuel Plant In The UK And Europe.

This is a paragraph.

The proposed plant will take hundreds of thousands of tonnes of household and commercial solid waste and turn it into clean burning sustainable aviation fuel, reducing net greenhouse gases by 70% compared to the fossil fuel equivalent – equal to taking up to 40,000 cars per year off the road.

Earlier, I quoted this about the process.

There are very limited emissions to atmosphere from the plant except water and carbon dioxide.

A lot depends on where the carbon dioxide is produced, but if it is produced by a well-designed process plant, it should be possible to capture it for storage.

There are also possibilities to reuse carbon-dioxide in the Fischer-Tropsch process.

Could Diesel Be Produced By The Process?

In the United States, Velocys are developing a project called Bayou Fuels.

This is said on the home page.

We are developing a plant in Mississippi that will create diesel fuel for road transportation in the U.S. It will process waste from the paper and lumber industries – woody biomass forest residue that would otherwise rot on the forest floor or contribute to forest fires.

It should be noted that this is said in the Wikipedia entry for the Port of Immingham.

In 2013 ABP began the development of the “Immingham Renewable Fuels Terminal” on the Humber International Terminal site, as part of a 15-year contract with Drax Power Station to supply biomass (wood pellet) to the powerplant. ABP’s total investment in biomass handling facilities, including installations at Hull and Goole was to be around £100 million.

As Velocys’s new  plant will be at Immingham, close to the biomass port, I suspect the answer is yes.

Where Is The Plant Located?

This Google Map shows Immingham Port and the area to the South.

Note.

  1. Immingham Port is towards the North West corner of the map.
  2. South Humber Bank Power Station is towards the South East corner of the map.

It would appear that the Altalto plant, will be located on an 80 acre site between the port and the power station.

There would also appear from Google Maps that the Barton Line runs through the area, which would surely be handy for bringing in the waste and taking out the fuel.

This picture from the Altalto web site, shows a visualisation of the plant, looking North East.

INote, what looks to be the railway, through the site in the foreground.

There are also a couple of informative videos, including one from the BBC, on this page of the Velocys web site.

t looks to be the ideal site.

How Much Fuel Will The Plant Produce?

According to the video on the web site, the plant will convert 500,000 tonnes of waste into 60,000,000 litres of fuel. I estimate that would be about 48,000 tonnes of jet fuel.

Could The Diesel Fuel Be Used To Decarbonise The Railways In The UK?

I believe that a substantial amount of the use of diesel on the UK’s railways will be cut by the use of battery and hydrogen power in multiple units and locomotives.

But some services like the heavy stone trains moving aggregates from the Mendips and the Peak District to London will be difficult to decarbonise, unless a locomotive manufacturer produces a hydrogen-powered locomotive with upwards of five megawatts of power. And that is a tough design challenge.

Low sulpur diesel produced from waste would be one way to reduce the carbon footprint.

Conclusion

It sounds a crazy idea to create aviation fuel and diesel from household waste!

Will It Work?

Consider.

  • It appears that most of the technology used to produce this fuel has been around for decades.
  • Sasol opened their first commercial plant in South Africa, using the Fischer-Tropsch process in 1952 and still use the technique today.
  • Oxford University have added magic ingredients to the Fischer-Tropsch process.
  • Velocys seem to have put in a lot of serious thought to get the Altalto project ticking all the right boxes.

The project could be late, but I feel it will deliver the main objective of converting household and commercial waste to jet fuel and diesel.
