Thanks again OHS I was always of the assumption that major burner and milling upgrades would be required at a substantial cost . As they say you learn something every day and i must admit have spent far too much focus on Meygen.
I think this was always the case oldtramp. My understanding is that the subcoal fuel pellet was developed as an alternative to coal and SIMEC contracted MHPS to design the burners for it to be utilised in existing coal fired power plants (Uskmouth). Infrastructure is already in place at UPS as opposed to plants being altered to burn gas or incinerator plants being built to burn general waste. This is why Uskmouth is so important and literally on a global scale! Once up and running and proven, the global take on of this concept would be.......(fill in this space with the most mind blowing statement you can think of!) China wants to be carbon neutral by 2060 so we have 40 years to continue to develop, improve and find alternative methods which will move towards that and although UPS does leave a carbon footprint, it is a step forward to replacing fossil fuel consumption, and I’ll say it again, on a global scale! Absolutely tremendous and very exciting to be on the cusp of ‘the mother of all corrections’ as TC would say! OHS
OHS or anyone do you think this means subcoal can now be used with little alteration to existing power plants ie a change from coal to subcoal with minimum costs?
“ “ Equally important, the flowability properties of the fuel have also significantly improved, allowing the fuel to be milled and distributed using existing mills, handlings systems and burners. “ If so that is a huge benefit
No probs oldtramp - I'm glad you posted the link as it allowed our research to clarify the actual make up of the pellets and inform other investors on here. Top job
No Phyl mate, the pellets are 100% waste-derived; made from 50% non-recyclable plastics and 50% biogenic (waste paper / cardboard) - so 100% non-recyclable waste. This isn't an update - this is more like a re-reading of the info that was already there and putting it into context.
Cheers for clarification oldtramp. Understood. Good news all the same!
Not 100 percent plastic phyl but 100 percent non recyclable. Still find this interesting as well
“ Equally important, the flowability properties of the fuel have also significantly improved, allowing the fuel to be milled and distributed using existing mills, handlings systems and burners. “
Am I reading this correctly that N&P have developed a fuel pellet using 100% from non recyclable plastic? If so, this really is a positive update and one that I wasn't expecting. Great work chaps! As oldtramp says, brilliant board.
OHS that is what I call an answer !! Thanks mate it’s great you can run ideas and finds on this board and to get an answer like that Is brilliant !
oldtramp - I see where you are coming from. I assumed the subcoal pellets were indeed 50% non-recyclable plastic and 50% paper/cardboard. Having just had a look at your original link, if you click on the 'Alternative Fuels' tab you will see that they have 2 paper and cardboard derivatives called Paper Rejects and Paper Sludge:
Paper rejects is the coarse residue coming from the pulping process. Next to fibres there is a significant amount of (non-recyclable) plastics in the material. Due to this fact, this material is very well suited to be used as an alternative fuel in waste to energy boilers, but it can also be treated further to be upgrade to an alternative fuel such as SRF.
The fibres in paper and cardboard can get recycled approximately five times, depending on the type of paper which is being produced. The fibres are discarded in the pulping process and end up in a sludge we call paper sludge. This paper sludge is a valuable resource for many industries, both as an alternative fuel as well as an alternative raw material. Lignite boilers co-combust paper sludge, taking benefit from both the heating value as the calcium which is in the paper sludge.
I think SAE missed a trick in pointing out that the 50% cardboard/paper they use in the pellets is not paper and cardboard that could be recycled further. It wasn't clear enough at first and I assumed this 50% could have been recycled for other purposes. So, the pellets are using 100% of non-recyclable waste which is fantastic!!
This states “The new fuel, produced from 100% non-recyclable waste,” could be nothing will check it all latter
At work at mo on my phone so need to check but I thought original was 50 percent bio mass and 50 non recyclable also “ The fuel can potentially also supplied as a milled product, like e.g. lignite. The higher density of the milled product compared to traditional (high quality) SRF and the flowability properties make the fuel suited to be used in existing handling systems, allowing users to quickly switch their fuel mix.”.

A good summary here:
In October 2019, Atlantis announced that it had awarded Mitsubishi Hitachi Power Systems Europe GmbH (MHPS) the contract to carry out the design and development of the combustion system for the flagship Uskmouth Conversion Project in Newport, Wales. This contract included the largest ever combustion testing of the waste-derived fuel pellets, which will be used as fuel in the plant, at Mitsubishi Heavy Industries’s Research & Innovation Centre in Nagasaki, Japan.
The test conclusively proves that a pulverised fuel burner based on MHPS’s DS Ultra Low NOx burner can be used to stably combust the waste-derived fuel unsupported – in other words without any oil or gas support firing.
The burner was able to operate continuously at 25 MW thermal power using the fuel and is comparable in rating to the burners required for the Uskmouth Conversion Project.
During the testing, MHPS established that it was possible to feed large volumes of pulverised fuel to the burner via a pneumatic system without disturbances, at a rate that is comparable to that required at the Uskmouth Conversion Project.
MHPS also investigated and confirmed that flue gas emissions were within anticipated levels and that the burner was able to achieve expected low nitrogen oxides (NOx) performance whilst maintaining low carbon monoxide (CO) levels.
Following the successful completion of the test, the final stages of the pre-engineering, procurement, and construction (EPC) detailed design contract are now underway.
Final design studies include using the successful combustion test results to validate the computational fluid dynamics modelling, carrying out a more detailed Uskmouth boiler system refurbishment design, and confirming the requirements for refurbishment and enhancement of the existing flue gas treatment system.
MHPS will have completed all of this work by Q4 2020 at which point they will be able to make an offer for a fixed price supply of the combustion system under an EPC contract with terms and conditions suitable for project finance.
The bespoke fuel pellets, designed and produced by project partner and leading Dutch alternative fuel specialist N+P Group, contain approximately 50 percent biogenic waste material such as paper and cardboard, with the remainder made up predominantly of plastic waste.

No mate, N&P produce solid recovered fuel (SRF) and refuse derived fuel (RDF) and then upgrade SRF and RDF into the pellets known as subcoal. Mitsubishi Hitachi Power Systems (MHPS) were contracted by Simec Atlantis to design the combustion system for these pellets. What makes you think the subcoal pellets have been upgraded further?
Hi chaps can you have a read of this it looks to be a newer version of subcoal ?
