Think we are close to another RNS
Mystic Meg has arrived š
I don't think it's anything to be excited about I'm afraid
Patent news is Possible but no major RNS expected in my head š·
Hey hang on there Castle I object to that statement... I've had many happy years poking around under blankets.
Could there be an RNS on its way?
The sp jumped up , might be a Indian captain just had a peep under the blanket decided to buy our stock with his cheap oil import from Russia and sales to the UK š¬š§
I love temple š
Iāve just ordered one of Temu. š¤£
Castle,
They had the drawings to build it theyāve probably got one ready for commissioning as we speak.š¤£
hey bert - thanks for the correction. i'm actually from a finance background, but i've been looking at att (advanced thermal treatment - basically everything that isn't incineration) for a long time so i've picked up a fair bit of knowledge, but i'm by no means an expert. what i have been able to do is to quickly filter out the usual bs, and there's a lot of it about.
@a*** - you'll get co2 plus all sorts of other emissions from pyrolysis and gasification also, on the basis that the resulting gases are burned (sometimes referred to as "oxidised") in a secondary chamber, either for heating or for the production of power (be that from sterling engine, orc, steam turbine etc). where a pyrolysis or gasification unit incinerates the syngas from the process they have to conform to the exact same ied emissions regs as incineration plants of the same scale. i'm also looking at eqt and have met with their chairman in the past (introduced my a family friend who was a former mp).
@divvyup - i'll have to look into the process more, but biochar to be used as a soil enhancer is only possible where the original feedstock is 100% clean biomass (i understand some of the feedstocks being used are, so that's good) but the quality, and therefore the use options for the resulting char depend heavily on the careful management of the thermal process, i've heard of pyrolysis for char production (see pyrocore, they are doing a trial with mersey biochar right now) but gasification specifically for char production isn't something i've seen much of, mostly the use of biomass in gasifiers is for waste management and heat / power generation, rather than specifically going for biochar.
@Steamineagle In the meantime the scaled FTU/DMG will do wonders for the company its profile its market cap & its worldwide profile. The process is already proven on its predecessor, the one making its way to Wales on a big boat is the next phase of development. You can always buy in at much higher levels when they break the ground with the 4 DMG's NH2 have commissioned.
It's all about risk versus rewards right?
OOPS Perhaps I should have used the term āthermal decompositionā. PHE have stated that the DMG process reduces carbon content recovered as biochar. Not clear on validity for specific feedstocks. Its potentially an additional revenue stream and If correct a soil amendment to improve soil fertility and seize carbon. Theyāve got to get it right at both ends, I don't want toxic tatties.
What does our A.I. think about #PHE https://x.com/SwazersC/status/1788216801848967570
Pyrolysis is same as in DMG & involves heating to high temperature without oxygen.
It is not incineration. In incineration oxygen is present & there is CO2 emission.
I think EQT also uses the similar process.
I suppose our system is hidden under a blanket on the ship , don't want them chinese poking around looking at it you know what there like with them cameras .

Hi Silver,
In Powerhouses case, DMG stands for Distributed modular gasification, if that helps.
You sound like you come from an engineering/ Chemical engineering background, hopefully you'll know if there is any difference in the two processes. All I know is it has always been said that the DMG unit is not Pyrolysis.
ATB.
@Testpack - by DMG I'm guessing you are referring to Direct Melt Gasification? Nippon Steel have a VERY high temperature Direct Melt Gasification tech. Gasification is hotter than pyrolysis anyway, but Nippon Steel's DMG is 1,800*c which is potentially 300-600*c hotter than some gasification systems.
Essentially pyrolysis and gasification are very similar, the main difference is the level of oxygen in the process, in gasification (DMG or otherwise) it's very little, in pyrolysis it is Zero. Technically the first phase within a gasifier is pyrolysis, but then oxygen, air or steam are used a gasification agents.
Both processes create Syngas.
Gasification will create ash, Pyrolysis will create char. Pyrolysis char of plastic heavy waste is hazardous, and will most likely fail WACC (I've had a sample tested and was informed by Whiteness that they wouldn't even accept it into their Hazardous landfill).
DMG is not a Pyrolysis. Syngas is produced ( we have been led to believe ) in DMG, therefore a different method is at play. That method is extremely high heat, to form a plasma, in an oxygen free environment. This is why it is such a difficult process, and the main reason for delays. Perhaps Castlepaul, with his in depth knowledge of PHE can tell us why the Combustion Chamber ( kiln) has been mfd in China.? UK has a plethora of refractory manufacturers who make the linings for iron, steel, glass making furnaces.
Hi Divyup, happy to help. The 24-48 hour time was a reference to a specific piece of plant, not related to PHE in any way.
I was providing an example of how test and demonstration plants aren't as reliable a source of operation as a 3rd party commercial plant (the operator in my example only had this single plant, which they were using a sales tool trying to get a Ā£multi million 50% deposit from prospective customers.
30silver: Thank you for your in-depth explanation of the syngas process with special regard too longevity of process, Down time/maintenance. I understand the temperatures within Town Gas kilns had an average life of 10 to 15 years before major refurbishment.
That said, I politely challenge the stated 24-28 hour cycle before shut down for maintenance. To clarify PHE cannot claim IP on pyrolysis but can and are with control systems, an essential part of the design maintaining efficiency and kiln longevity.
Thanks 30silver.
So the Holy Grail of all these systems is basically the same for everyone!
Extremely pernicerty and so finely balanced to be almost impossible to achieve.
So farā¦.
As ever, we need a full scale operational system underway.
Good luck all.
35 days to go on the ship .
Gas cleaning system and the Gas analysing system being made for completion..
Protos news after our (FTU) has been completed , commissioned and fully banging out some good results,,, ledzep might give us a report before Christmas!!
Plenty of news a head .... bosh
Getting exiting

@SteamingEagle - I'd not heard of Compact Syngas Solutions, however I do know some of their board from their previous positions, particularly the Commercial Director who I've done work with on ORC units for power production. He's also pushed another system, Pyrocore (well worth a look, it's good kit, just very expensive and very particular about feedstock).
The CEO is formerly of RefGas - another failed Gasification company, founded by his father, George and one that also claimed a patented process for gasification.
Downdraft gasifiers are great, as they do produce a lower tar gas (because the tars crack down through the oxidisation zone) and this is very useful where you are using biomass as a feedstock, as that will naturally produce more tars. The issue is when someone wants to put plastic containing waste into a downdraft gasifier, because the main drawback of downdraft gasifiers is ash bridging / clinker formation especially from low ash melt point materials such as, you guessed it - plastic.
One thing on their website set of a massive red flag - this quote:
"CSSā innovative patented processes, enables us stand out from the competition, add to this our seven stages of syngas cleaning and cooling this ensures that our product gas is not just ultra clean but of the highest quality. In fact, the syngas produced by our system has been proven and accredited to be cleaner than natural gas, making it one of the purest fuels available for generating power."
The second half of that statement is patent BS - there is no way any syngas can possibly be "cleaner than natural gas" and most Syngas is completely unsuitable for use in an engine, many have tried, all have failed (when you're looking fro 8,000 hours per annum run time - not a demo plant that can run ok for 24-48 hours to show how great it is, only for the unit to be shut down the minute the clients leave the site, lest it burst into flames. Then starts a 3 week maintenance period before it's ready for another 2 day run.
Hopefully patent news soon !!
