Risk versus Reward
This can be defined in many ways, but is usually limited to 3 key areas:
1) Fitness for purpose
2) Indemnification
3) Scalability
FITNESS for PURPOSE
In order for a laboratory developed technology to be Commercialised, the single most important aspect is its Fitness for Purpose. In other words - it will actually do what it was designed to do.
In the case of Torrefaction technologies, this is a yet to be realised goal. Even the best research organisations in the world, have only been able to create a reactor that works at small scale. Even then - the product derived from these bench-top and lab-scale reactors isn't ideal. On top of this, NONE of the current developers are willing to offer the GUARANTEE that their technology will ACTUALLY WORK!
I suppose one could be convinced that if a process works at 10 or 100 kg per hour - it will work just as well at 1,000 kg per hour or more. Nothing could be further from the truth. One has to completely understand the mechanism of torrefaction, BEFORE you can fully appreciate the height and breadth of this hurdle. Our experience is that Investors are unwilling to back something, unless there is either a prior version (that the new developer is seeking to improve upon) or a significant guarantee from the technology owner.
As there are NO operating commercial torrefaction reactors anywhere in the world - the first to develop one takes assumption of all of the risks. Unfortunately - it doesn't necessarily follow that they benefit from all of the rewards as well. In fact - it is highly likely that other developers will benefit MORE than the pioneer. The reason for this is simple;
First to "prove" the technology will change the view of investors on it's viability. That is to say - once SOMEONE, ANYONE has successfully created a Commercial reactor - the investment industry will, as a whole, recognise and ACCEPT that it is now possible. PRIOR to that, (which is where we are today) it is only a THEORETICAL technology. I recall a comment I received about a year ago with respect to torrefaction - "It didn't work 15 years ago - and it WON'T work today". This kind of self-limiting thinking and defeatist attitude runs rampant amongst those who have no vision.
On December 13, 1903, man had never successfully achieved powered flight. On December 14th, the entire world changed when a couple of bicycle mechanics named the Wright Brothers, managed to get what appeared to be an oversize box kite into the air under it's own power. In the same way - 30 seconds AFTER the first Bio-Coal exits the first reactor - the ENTIRE world changes. Most people believe that the telephone was invented by Alexander Graham Bell; The steam engine by James Watt; the light bulb by Thomas Edison; and the radio by Marconi.In fact - here are the Inventors (NOT The ones who commercialised the devices)
TELEPHONE - In 1860, an Italian named Antonio Meucci first demonstrated the working telephone
LIGHT BULB - Heinrich Goebel was likely the first person to have actually invented it, back in 1854
STEAM ENGINE - Thomas Newcomen an English blacksmith, invented the atmospheric steam engine circa 1712
RADIO - Mahlon Loomis - He is called as the "First Wireless Telegrapher" - In 1868
In each of the above cases, the actual inventor received very little benefit from the his labours. It was the names of the person who COMMERCIALISES the invention that became the household word. I have the feeling that torrefaction will end up being very much the same. There are literally HUNDREDS of Companies right now who are "watching" torrefaction closely. Many of them are hedging their bets by contacting ALL of the developers, and gaining an understanding of what they are doing; and how they are doing it. In this way - they hope to be able to "jump in" JUST at the right time, to establish a relationship with the developer. The risk associated with this strategy, of course, is that there is no "shot to nothing". Many of the Torrefaction developers are speaking to several potential Customers (predominantly for the product - NOT the technology) leading each to believe that THEY are the "chosen" ones. Without however, some "consideration", this is all just talk. (Something about "put your MONEY - where your MOUTH is!) It will undoubtedly create some interesting dynamics as things get close to the ultimate end, and the "winners" and "losers" are revealed.
INDEMNIFICATION
The path to commercialisation is invariably paved with many, many potholes. A major one of these is the liability associated with the design and construction of a machine that has the potential to be a rather large BOMB. (After all - a 5-tonne per hour reactor will contain some 25 tonnes of wood chips at any given time, containing a total calorific value of some 500,000 Mj of energy; operating in an anoxic atmosphere, at very close to the autothermal (exothermic runaway) reaction point; producing combustible and potentially explosive gasses in copious amounts. What could possibly go wrong?
Needless to say - next to the bean-counters (Accountants - who seem to run EVERYTHING) it is the Insurance underwriters that have the most influence on Commercialisation. There is this small matter of
Product Liability that needs to be addressed. After all; if you sell a machine and the customer fills it full of wood chips, and it Catches FIRE or explodes - this is NOT a GOOD thing. It's made even WORSE by the fact that there are people running the machine, and these types of events can ruin their WHOLE day.
SO - the underwriter types tend to be very careful about ensuring that the technology is safe and suitable.
SCALABILITY
One reactor does not an industry make. Neither does 2; or 20; or 200 for that matter. The key here is that scalability cannot be an arithmetic exercise - it needs to be an exponential exercise. The vast majority of the current technologies in development are already too expensive to be economically sensible. There are some who believe that the economies of scale will reduce this cost - however it is unlikely. The complexity of the machines, combined with the the complexity of the process, necessitates an unusually high Capital cost.
Optimisation of the system would require a whole new philosophy of operations. To that end, one needs to look at the design from a completely different perspective. here are the parameters that guide this philosophy;
1) SIMPLICITY
Understanding the process so completely that there are no extraneous steps, and only the bare-essential components are included.
2) DURABILITY / RUGGEDNESS
The more sophisticated a machine - the less durable and rugged it tends to be. Ideally - the reactor should resemble a 70's vintage Land Rover - rather than a new Rolls Royce.
3) FLEXIBILITY
This is ALL about Systems Integration and Process Control. Almost ALL of the existing technologies are relatively limited in their parametric control. As a consequence - the spectrum of feedstock that they can process is the narrow end of the wedge.
4) EXPANDABILITY
As SI and Process Control represent a large portion of the CapEx; it makes sense to have the ability to expand this function to 2, 3, 4 or even more reactors. Limiting the PLC to 1 reactor per computer (actually - 2 computers as redundancies are necessary for safety) unnecessarily handicaps expansion capabilities.
5) MODULARITY
Undoubtedly, the technology will develop, and improvements in the process will evolve. A non-modular System would be left in the dust of "built-in obsolescence"; UNLESS serious consideration was given to "future-proofing".
It is fair to state that many of the current designs and technologies have travelled so far down a single path, that they are now past the point of no return. This is, in many ways, quite tragic, as the ultimate goal may not necessarily be where it was first anticipated to be.
The Company that can assemble all of these features, is the one that will ultimately control the market for the foreseeable future.

A sad day for Torrefaction
Each day I look to see if that elusive "Eureka Moment" has finally arrived. The moment when a Company or Research facility completes the construction of a Reactor; fills it full of biomass; turns the key, and it spits out Torrefied Wood.
One such moment I have been waiting for with anxious anticipation is the Start-Up of the Stramproy-Green / 4Energy Invest project. Having met the stakeholders and visited the facilities under construction I was SURE that THIS would be the FIRST to market. Alas, such was not to be the case.
On February 2, 2009, I received the following press release "4Energy Invest starts the construction of a lar..."
http://www.investegate.co.uk/Article.aspx?id=20090202170000H6627
WOW, I thought to myself; now HERE'S a team that can ACTUALLY make things happen. This would be a WORLD'S FIRST! A €13 million development that has all the makings of a winner! A quick look at the 4Energy Invest stock price revealed the market shared my beliefs and enthusiasm.
7 Months later - another ASTONISHING announcement; Stramproy Green had entered into a 5 year agreement to sell Bio-Coal to Essent Trading.
http://www.rwetrading.com/_internet/PDF/In_the_Press/Deal%20of%20the%20year.pdf
The press release was clear that this was the largest deal for Bio-Coal signed, ANYWHERE IN THE WORLD. FANTASTIC, I thought - A prominent Trading Company; a highly-experienced and credentialed Engineering firm; and a successful Power Generating Company all coming together to a common end. The heading of the Press Release was "DEALS OF THE YEAR!"
THEN - the pieces started falling apart. In December, the 4Energy Reactor was to be up and running. It DIDN'T happen.
On may 6th, 4Energy released their trading update for the first quarter 2010. In part it read -
"The main contract that Renogen (a Wholly-Owned subsidiary of 4Energy) signed for the construction of a large scale torrefied wood pellets production facility in Amel ("Amel III") included a provision of 340k EUR for delay damages in case the commercial operation was delayed beyond the planned take-over date. As of 31 March 2010, it can be firmly established that the amount of delay damages will be due by the main contractor." On December 31st their stock dropped to a low of €4.52. Whether this drop was a consequence of the reactor not completing on time is purely speculation.
This however, was NOT good news. I found it very hard to believe. After all; RWE (parent to Essent) has many highly skilled experts in this industry (having gained much experience, I assume through the investment in Toppel) and wouldn't endorse a technology that would ultimately fail? In my mind - I reconciled myself to the belief that this was just "growing pains", and that ultimately - given enough time, Stramproy-Green would be able to get it sorted out. Remember - there was the small matter of 450,000 tonnes of Bio-Coal that had to be produced for RWE in the future, using the same technology. Even at conservative market values of €180.00 per tonne - this represented €81,000,000.00 of business. (Not a small sum - even by Utilities standards.) By comparison - a few hundred-thousand Euros was a small price to pay in non-performance damages.
On the 15th of January, 2010, KBC Securities Issued an update entitled " 4Energy Invest - BIO-COAL, the GAME CHANGER". The then-current share price was €5.17 - but they predicted a "target price" of €7.80. Of course - their recommendation was BUY! It would appear from this market intelligence that EVERYONE believed that the problems were just small challenges that could be overcome.
https://www.4energyinvest.com/document/D132_20100115KBCSCompanyNote.pdf
Then the Axe dropped yesterday. "EPC Contract with Stramproy Green Technology BV TERMINATED!"
https://www.4energyinvest.com/document/D166_20100624_4EI_Title_EN_Final.pdf
The day before the announcement, the stock dropped to €3.35. In ONE DAY - the stock dropped 9%. To add insult to injury - it is now sitting at a mere 43% of the KBC prediction, made just a couple of months ago, and represents a HUGE drop in value to the Company.
My heart sank.
Surely this wasn't the end?
What about the future?
I suppose that the words of KBC were quite prophetic, in that Bio-Coal is the GAME CHANGER. I don't suppose anyone fully realised that the ABSENCE of Bio-Coal would also change the Game - in an unfortunate way.
As for us, we will quietly continue along, slowly, surely, and methodically engineering our reactor. In a couple of weeks, we will be firing up the DIAMOND Synchrotron,
http://www.stfc.ac.uk/About%20STFC/5807.aspx,
and shoot a few 6.3 TwE particles (at almost the SPEED OF LIGHT) at some biomass to watch what happens. This lovely billion-pound instrument has the ability to track the devolitilization process, second my second, on a molecular scale.
After that - it's in to the Rotating Anode X-Ray Analyser. In here, we can heat the biomass to 2,000 degrees and track the kinetic and chemical breakdown on a primary, secondary and tertiary basis. All of this is geared towards our "holy Grail". That is - a full and COMPLETE understanding of the process - so that once the reactor is built - it WILL WORK, and do "exactly what it says on the box."
Stay Tuned - this is getting Interesting.

Torrefaction Technology - Past and Present
In fact, there are almost 100 Patents and Patents Pending with respect to the process (ours included). Over time - each one has taken a slightly different approach to the one before it, which has sometimes lead down the path of no return (a path to destruction) and other times, has lead to an improvement of the previous iteration. These can ALL be found here http://www.ipef.br/eventos/2009/biomassa/11-Didier_Leboutte.pdf
Below are a few of the patents, and how "modern" advances are directly related to them.
On January 15th, 1901, a certain ALBERT COMTE DILLON DE MICHEROUX was granted a patent, number CH20332, entitled "Four de séchage et de torréfaction" (An Oven for Drying and Torrefaction)
Most Modern reactors were based on the work of JACQUES LECLERC DE BUSSY in his Patent "METHOD FOR PRODUCING TORREFIED WOOD, PRODUCT OBTAINED THEREBY, AND APPLICATION TO THE PRODUCTION OF ENERGY", patented in 1986.
PCA Bergman (Energy Centre of the Netherlands) holds 3 patents, EP1969099, NL1029909, NL1025027, granted between 2005 and 2009. While ECN is considered the "leading" technology provider, this remains to be seen. A failed attempt 2 years ago to commercialise their technology has been resurrected recently with a new Commercial Partner, HOWEVER, even that Partner is STILL "considering other technologies". (I'm not quite sure why???)
In 1989, Roger Gerard patented a machine that is virtually identical to the current Agri-Tech Producers machine, developed by Chris Hopkins at the University of North Carolina.
In 2007 GERARD HUBERT JOSEPH RUITERS received a patent for "METHOD FOR THE PREPARATION OF SOLID FUELS BY MEANS OF TORREFACTION AS WELL AS THE SOLID FUELS THUS OBTAINED AND THE USE OF THESE FUELS". This is now the process that Torr-Coal are using in the Netherlands.
In 2010, Wyssmont patented their technology (US2010/0083530) by converting their Turbo-Dryer into a so-called torrefaction reactor. Over the past 18 months, Integro Earth Fuels have been attempting to make it work. After much fanfare in the beginning, it would appear that they have fallen below the RADAR, as nothing appears to have come of it.
So, there you have it; Past and present; state of the art and old hat. Funny - but the more things change, the more they stay the same.
