Good info on Acrevo, Keith, that's a study worth a read for sure.
RE: blending additives: Proprietary additives can be an enabling technology. They enable the largest part of the fuel (local plant oils) to be easily made locally at low capital cost from local materials. They certainly can and do work, technically, and provide confidence that (if they come from an established and reputable supplier) they will perform as promised. They can be an economical alternative in many regions. Combined with heating approach, in either a single tank or two-tank system, they will work even better. They are quite safe, requiring less equipment and somewhat fewer safety precautions and training than the use of batch transesterification techniques. In this case, additives can eliminate the need for a large up front capital expenditure. They lend themselves to small scale processing. A "canoe paddle" and a drum of additive replaces a biodiesel processor plant, drums of methanol, caustic. It eliminates the glycerine byproduct, which may or may not be in demand locally. Overall, it simplifies the process for people. For example, they can be used to make up a start/stop fuel easily and quickly, used either neat or in a blend with diesel fuel. They can be used as cold weather aids for SVO within an SVO system - for the especially cold times of the year only. That sort of thing. They can be licensed for regional production by local entrepreneurs who have the right skills and capacity to take on such production. Yes, some are patented. And that means that the patents are made available to study, learn from, change, improve on - and they eventually expire. The inventor benefit of a patent is relatively short term and low cost to society in relation to the knowledge that is disseminated. Are they perfect for local production? No, they are an outside input of course, but not bad, overall. Useful for the purposes of many people trying to find their way forward and get going quickly. ----- BTW, for WVO blending, new oil is always an option too. It's thinner than WVO usually - sunflower oil is thinner again than Canola, our oilseeds guy informs me. So, cold pressed sunflower oil, and WVO?
