We have spoken with our contact, and we are encouraged to submit an EOI for the CRE Grants program. Given that everybody else is submitting EOI’s for Wind and Solar systems, we may be in with a good chance. This is a response sent in after it was posted Closing 21 Feb – excluded, on February 13, 2013 by co2land
In fact three relevant responses came in and each had a story that you might be interested in:
Renewed Carbon – Have a BioHub design. They have a set of engineering firms in Newcastle ready to: Design the plant, Build the plant, Run the plant for 12 months, Take all the start-up risks, Sell the operating plant to the eventual owner.
All they need is about $12m !!!
They are working towards a pre-feasibility study to establish whether they are just dreaming (They believe such a study will a green-light the project). But the study will cost several hundred grand!
It is matter of hurdles (one at a time) and a simple process of: let’s get the money for the Pre-Feasibility Study and work from there.
Part of the reason for their enthusiasm is they are aware of working Pyrolysis plants in several places in Europe, as such they are confident the ‘Commercially Available’ constraint in the EOI closing 21 Feb 2013 should not be a problem.
With that said, I wonder if many are aware of the more sophisticated Veolia WASP project at Woodlawn, via Tarago in NSW. This project has been held up in NSW Planning approvals for some time now and as we have spoken to the engineers at the plant – it is a source of great frustration.
Then a more detailed retort from Peter and Kerry Davies of Real Power Systems (who have built their gasifier and Pyrolysis retort machine in Australia and demonstrated its commercial application in Australia) lament the issues they have had since showcasing the capabilities on the grounds of Parliament House in 2009). In this response they are responding not only the Closing 21 Feb story they are also referring to happenings in the prickly exchange between www.newmatilda.com and City of Sydney Tri-generation project, and the general stonewalling they have encountered with their offering in the quest for a commercial outcome. In direct quote:
“Thanks for the link, we just read through the three associated articles:
The attacks are coming from the green’s associates and heavily rely on BZE, a Melbourne University academics club who want Oz to go solar thermal immediately and trust that in doing so costs will fall and engineering problems overcome. This involves putting several thousand square km’s of solar arrays down in adjoining rural areas…
The core arguments against the renewable component of the plan centre on biogas, which is produced using anaerobic digestion and therefor predominately methane (85% CH4). We would consider these arguments to be largely valid although they don’t go far enough, the cost of efficient closed cycle anaerobic digesters is millions of $ per MWe of capacity and are prone to significant operational problems. In the EU it has been found engines running on biogas have difficulty meeting emission guidelines as some fuel is not burnt (escaped methane) and running excess oxygen to correct this then results in NoX emissions rather than CH4, there is a lot of work being done to overcome this limitation.
These arguments though are not valid at all for gasification whose output is “producer gas” which has <1% methane and the fuel gas component is CO & H2, much cleaner in combustion and not subject to “methane leaks”. Gasification also is far more flexible in its feed stocks which can readily include waste paper with plastics contamination, and is easily topped up with solid fuels produced from plantations, crop residues or RDF pellets.
NoX is easily managed in a properly engineered system running on producer gas since its formation is temperature and free oxygen dependent. Modern “lean burn” engine technologies combined with rapid exhaust cooling (via cogen) readily address the emission concerns. Direct combustion systems are more difficult, the critics seem to be confusing the two.
Trigen should be eminently suitable for Sydney so long as it genuinely includes absorption chiller technology for the building climate control required in warmer months. We don’t believe waste heat and inversion layers should necessarily be an issue so long as the trigen plant is not using fossil fuels or high methane biogas. Indeed with some lateral thinking and applied engineering the waste heat from higher rise buildings could be used through thermal siphoning to alleviate air pollution at street level.
We are aware of some very clever “Urban food production” systems that can produce very high outputs from small areas using aquaponics (fish and hydroponics). The rooftops of many high rise buildings would be eminently suited with proper planning to include these which then turns the total system into a “Quad generation”, utilising CO2 from the engine exhausts in the greenhouse above and providing local restaurants with fresh fish and vegetables grown in their own inner city building or precinct! Such innovations are we believe relevant now and can only become increasingly important for the future of sustainable cities.
Heightened ambient noise is an engineering/$ issue. A couple of years ago we responded to a request for tender for a cogen plant at a public swimming pool. The EPA imposed a noise limit of 32 decibels (it turned out there were dwellings within 20m of the installation site…). To put this in perspective such a noise limit can be exceeded by the act of sitting down in a country library and opening a hardcover book… We found a solution with pre-cast acoustic chambers from a Sydney supplier which added about $80,000 to project cost (yes you can also cast in situ). You could rev a Harley at full throttle inside one and not exceed the 32DB limit outside. To give you some idea of what this means in practice the fan running on the RPS system demonstrated at Bungendore for REDay generates 55DB.
Finally Origin/Cogent might consider the following: The RPS plant being commissioned at Sutton at the moment just took delivery of 80m3 of sawdust for further client trials. This plant when operational in the next week or so will consist of:
Gasifier – clean fuel gas and high temperature treated biochar output.
This char output can be used for water filtering and odor control amongst other external applications before going off to be added to compost for final recycling & CO2 sequestration.
Integrated pyrolysis retort – operates off a portion of the gasifier output so as to be more consistent, controllable and able to handle high/variable feed stock moisture contents, capable of sustained temperatures >650oC. Outputs biochar or torrefied biomass depending on temperature/residence time profile selected so effectively could replicate any typical biochar specification required or alternately pre-condition solid fuels for the gasifier.
Also can provide process heat for a range of purposes.
Electricity generator (20kWe) – Dual fuel diesel & producer gas from the gasifier . Typical diesel displacement when the gasifier is running would be 85% (reduction in normal diesel use). Later we will trial recycling a portion of this final exhaust back through the gasifier to re-crack some carbon dioxide (CO2+heat= 2CO) further reducing nett emissions.
We are also currently refurbishing a 50kWe straight gas industrial genset to add later in order to achieve 100% organic power.
Briquette press – for hot briquetting product directly out of the pyrolysis retort. (This is part of RPS’s R&D looking at subsequent material handling/transport/application strategies).
This briquette press is a proprietary design that we own the rights to and is able to be locally fabricated by any competent engineering shop so is not a high cost imported item.
So it is really a combination proof of concept/commercial plant that goes beyond just a functional bioenergy/char retort design and looks more at a whole of system farm scale factory with core components equally at home in the basement of a building in order to give flexible outputs that maximise benefits. This plant is readily brought up to the scale some companies have received offers of multi-million dollar public grants to build…but still haven’t been able to do so.
All of which has been done not only in the absence of government grants or sucking in market venture capital but also in spite of direct obstruction and commercial bastardry by vested interests. What might be described as “Success against Uncommon Odds”.
If the City of Sydney/Origin/Cogent trifecta are genuine they need to stop playing around the edges and get serious with some sort of supportive funding delivered through a credible pilot plant trial to publicly validate what we already know, instead of waiting for people like ourselves with real solutions to solve their problems for them entirely at our own expense.
Best Regards, Peter & Kerry”
Then from George Paulos, where is writes of his IMPLETERRA new Plasma Gasification System:
“Thanks for connecting with me.
And as you have already pointed out: YES I love my work !
Hopefully we can be of fruitful service to one another.
I would like to move some things in Down Under with you.
For example: Our new Plasma can extract precious metals from ore.
This is currently being tested in our lab in the US.
Thus all these hazardous chemical for extraction get needless AND
of course the overall calculation for the mining company gets CHEAPER In this sense its a win-win for all parties involved: We and our environment and the company and the economy ! And also: These Plasma devices cannot be sold, only leased based on Power Purchase Agreements. Thus no investment necessary ! “
On reflection of what George has said, and repeated by Real Power Systems: The way grants programs are administrated may be what is wrong with the industry, in this it is meant: Why do you need $XXk grant to write a pre-feasibility study and then go to a prospectus costing $XXXXXXK in order to persuade $XXm from investors given that the askers apparently already know the outcome of a larger feasibility study, or learnt from past mistakes…. Would it not be more sensible to do as the UK Government do – have a department and a fund set –up that is open to all, rather than a select few. The caveat is if you can prove the need, that sufficient testing is done and you can show it could work, and the ability to be an entrepreneur – be a doer not just a talker. You will be asked how much do you need and so on. No nonsense approach that makes the bankable process much more streamlined.
CO2Land org thank each for their encouragement. Clearly these are also worthy of encouragement because they each solve real problems to what we have now, WHAT TO DO to turn waste to energy and take the pressure off virgin materials being required every time!
