Vision 21 is an ambitious, forward-looking program to develop substantially improved technologies for using fossil fuels (petroleum, natural gas, and coal) for the production of electricity, process heat, transportation fuels, and chemicals with greatly reduced environmental impacts.

Vision 21 should define specific emissions goals for eliminating environmental pollutants from Vision 21 plants, including a precise definition of the "near-zero" emissions. Integrated plant designs should include processing of periodic wastes, such as spent catalysts, saturated absorbents, contaminated solvents, and water-treatment sludge.

In other countries, such as China and India, where development decisions will greatly affect global carbon emissions, the situation may be different. The Vision 21 Program Plan makes few references to opportunities for marketing Vision 21 technologies in developing countries.

From page 108... ...
Advanced combustion technologies included in the DOE core powergeneration program are limited by practical engineering to efficiencies of 45 to 50 percent, which are substantially below the Vision 21 Program goal of 60 percent. In addition, the dilute carbon dioxide stream from combustion processes is more expensive to separate from the plant effluent than the concentrated carbon dioxide stream from a gasification plant.

From page 109... ...
The commercial success of the Vision 21 Program will depend largely on the successful development and demonstration of cost-effective coatings and structural, membrane, ceramic, and catalytic materials for Vision 21 systems and components. Nevertheless, the Vision 21 materials research program is not well defined for structural or nonstructural materials.
