The proposal works from a scientific perspective. There are serious concerns about the uniqueness of the proposed idea. It needs more analysis on the implementation and the actual costs of infrastructure, converting cars/buses to take advantage of the new fuel, and mapping some key facts. For example, it needs to analyze the actual potential of this energy source. Here are some ideas: how many plants could adopt this technology today? How many plants can be built in the next, say, 30 years if this technology is successful and consumers adopt it? What is the market for fertilizers? How can this fertilizer compete with current fertilizers? Second, the proposal provides no analysis of the costs. For example, it should analyze and provide the approximate cost to build a plant, convert a vehicle, etc.
The challenges are myriad and mostly non technical; they have to do with local capacities in developing countries, the enabling environment, the lack of proper markets for the use of treated sludge, etc.
Some people are doing this very well today. Many others are constrained, not due to technology, but to regulatory and business model barriers. This is something that should be pushed from a policy level, but not a technology solution right now.
