Dr. Eddy Isaacs, Executive Director, Aberty Energy Research Institute, continues his keynote speech regarding carbon emissions and capture at the Oil Sands Heavy Oil Technologies Conference, July 2008.



I. Okay. Okay. But we do have. A mountain of -- that had been produced since the since the production of it since upgrading of the oil -- And you can see from this chart this is this is this amount has been rising quite significantly. -- Stockpiles of -- Coke given in the figure. The current pet -- production. 20000 tonnes per day and projected. Production of double that by say it's -- 2015 time for an. It represents a huge energy source. -- And as an example that I gave here a thousand megawatt -- CC plan would be using something like 6000 tonnes per day for that folksy countless. How many of these we could -- if we could -- freely admit this -- to today's world. And you can also calculate. How much natural gas this can displace I haven't done that here. But certainly it's going to displace a lot of the natural gas use if we could use that -- and of course. We could use a pet -- for words steam generation we don't have to go through gas station to do that. We can we can do that through oxy combustion as is being done. At least in a pilot scale. Ian in in California and elsewhere using. Oxy -- combustion. Such as. What device technology as as a good example. With gasification not only can we produce steam into hydrogen and power. Through that. But again the major barriers CO2 emissions -- of course other emissions of concern and that's where. -- capture and storage will play a big role in trying to. Allow us to not only used the the -- -- but also. Two be able to sequester the emissions that come -- -- that. There's going to be a talked -- later on this afternoon about the nuclear Euro stands where applications -- -- -- But I got just wanted to put up this slide thickness we certainly I think that there is potential here. -- -- in the process of exploring that potential in the oilsands. And it really depends very much on the economics of -- placing natural gas and the carbon penalty that's associated. We have. We have we with. While sands production. But there are some reliability issues and here it just mention a couple of these and that is the availability of skilled labor. Given the fact that there's a number of operating nuclear plants. Hold number of them under construction there was an announcement yes yesterday -- the day before yesterday. The UK. Putting out at eleven new nuclear plants. By 20/20 or 20/20 five. So. A large number of them being considered so that's major issues. From an oil -- perspective of course it's the licensing process and its alignment. With the building. -- facilities. But there are a number of opportunities. And that is -- that involves matching the reactors to push potential all -- application listed. All of those that came to mind. Including CCS -- these -- requirements. -- new wave of oilsands electrical heating production technologies talk about that in a minute integration steam methane reforming. Hydrogen production for upgrading. As a as another example and in my view integration with gas station because you can use. Nuclear to produce oxygen as well it's hard and so the auction could be integrated with us if so there's a whole range. Potential for nuclear. But we need to match very accurate the reactors need to match -- licensing process we've wells hands applications. The other questions that I amassed quite frequently. He is about biomass and what's the potential for -- -- In in oil sands well we really don't think that there is a lot of potential for a -- maps and oil -- But we are looking at the usability of biomass in Alberta we've done that in conjunction with. BC -- -- -- BC part of this. To look at where is -- biomass available and how much it can be used we think that the application is going to be. In remote communities or communities that can go off grid. If in the future. As energy becomes more expensive. That's an option for them to consider. We've been working -- the Edmonton Waste Management center issue and again a phased approach. To design hand we're in the phase of designing and building -- demonstration. Product project. For looking at municipal waste forestry waste agricultural waste but again factors. Very good match here -- wells it's needs. The quantity -- quality of the -- -- just just off here to do that but there are. Obviously other applications. And then. Altogether -- wanted to talk about increasing efficiency of operation reducing energy intensity of existing processes and switching to new generation. Processes. And a very. Socialists is very systematically what I wanted to show is the potential for -- each -- reductions. But of course in the oilsands are also talking about natural gas reduction in water use I want to show that's dramatically. On the -- X axis talking about. Natural gas and water use reduction. And on the Y axis the potential for each -- reductions and berries dramatically kind of -- Where we are current technology. Showing the mining extraction. -- DC CS. Sort cyclic steam stimulation. The upgrading as well placed on here and upgrading its -- hierarchy here reduction because there are sources skewed to -- can. There are more concentrated and are more amenable to -- capture -- example. Also putting here -- -- and processes although this is not a commercial technology can be commercially mr. Ridley. And it's an advanced stage. Development. I've put an arrow. Saying that this has a lot of potential for moving up. I've seen I've sought presentation -- can -- south technology salt and -- process. Which indicated that there is a lot of potential for this technology to. Create greater efficiency. What about. The next wave of technology -- included here. Integration with -- clear integration with. -- thermal. Integration with gas education. And also the combustion. And electrical heating and I wanted to give example of all of these. -- some movies anyway starting with. -- solvent processor is an example from work that was done -- -- research council. The so called the F -- the visitors. Several of these analog -- production rates from the lab. Showing higher recovery. And then what you see is much reduced energy requirements in fact the energy requirements for. For both energy and water use went down by 45%. And that. Gives you reviews GHG emissions now. It turns out that the work it and -- has done in the field has shown with with variation of this process has shown. Very similar type of numbers. So it's not just lab numbers but I would call them -- Mansfield. Testing numbers. -- a great deal of potential. The other is the use of -- stable and secure combustion. We're instead of using senior year essentially injecting oxygen into the ground or air into the ground. And burning part of the -- to produce the heat required. To produce the oil this is the work that's going on. Today. By Petra Bank so called type process. To -- that air injection process. And it's in this stage of having feel to pilot trials. And eventually -- will go into the stage. Designing commercial operations obviously this kind of technology. Needs a lot of work. And many field trials in different sites different police locations before it become commercial. But I think it certainly has a great deal of potential. The last. Technology -- wanted to talk about is the whole area of electrical heating give an example work we're doing -- ET energy. On oil sands production this is pilot that's taking place and and -- -- But there are. Technologies like this error. Also being discussed the talking this. Conference on very similar technology. But also shell has been experimenting -- electrical heating yet. If you like it coking Reza war situation with this particular technology. It is completed pilot trials short distances between miles and now is moving to increased well spacing. -- -- the design programs I think these types of technology really do have a lot of potentially reducing natural gas. And water use and of course two missions. So that brings me to summarizing. What I would consider the opportunities. I think first of all in terms of next generation processes I think next -- additional -- production. Technologies. Her going to be coming up. To speed very quickly -- the accelerated by the need to -- mitigates carbon emissions. And also natural gas use and water use I think there'll via an accelerated. Strategy by companies to look at next generation processes. In terms -- fuel switching. I think -- that. This makes a lot of sense when you have high valued fuels and petrochemicals. That can be produced from low value -- to mention that cool that. Actual teams and pitchman residues would be another coal would be and -- source. That because a high value will compensate the cost of carbon capture. With the added value if we can use enhanced oil recovery. Three -- recoveries this as -- tension. And so I mention the classification of coal Pepco -- rescue. And the integration. Petrochemicals. That can meet the needs for -- for hydrogen and steam and power and in many of the studies that have been done. Getting that hydrogen production and power. Together. Provides you with at least cost options so this is this is certainly. Something that the think needs to be pursued quite vigorously. And of course I mentioned the integration of nuclear with the oil sands operation. We think that next generation reactors will have best potential for it. And finally to talk about carbon capture and storage is as I mentioned -- -- -- Weber mentioned very important strategy for the province. The low hanging fruit -- CO2 from steam methane reforming facilities that produce hydrogen for upgrading. In Banfield separation you yet concentrated stream of about 95%. -- -- use that. You know compression is gonna be the major factor here. And also in PSA separation have 40% countries -- he's there. Way above. Lou gas -- streams. So it they lend themselves -- much carbon capture and storage. I think there has to be tremendous emphasis on increased efficiency of carbon systems. Because we need to eventually be retrofit legacy plants and industrial boilers. And so. The focus ought to be on systems that are best adapted to low concentration. Streams of flue gases. Carbon capture and storage as -- mentioned needs vanguard large scale projects for. -- prove their viability and in this case the Alberta government has stepped forward and said we're gonna put two billion dollars. On the table. We challenge industry to come forward and provide it. You know at least equal investment. With the government investment in carbon capture storage. And make this. Large scale projects viable -- be. Effectiveness of them -- moving forward. So with that I think -- -- Thank gate. Okay. Okay.
