One of the guiding principles of the Vision 21 Program is that the system synergies realizable from combining several advanced technologies will lead to viable economics for clean coal technology. In order to make a credible case for industry to commit to commercialization and to partnerships with companies outside their traditional areas of business, it will be essential to build and validate robust models of system design, performance, and costs.

The ability to create and defend credible engineering models and cost estimates of Vision 21 plants should be considered one of the most important products of the Vision 21 Program. In many ways, it is this capability that delivers the detailed and actionable “vision” of Vision 21.

Computational modeling and simulation consist of two general project areas, which DOE calls (1) simulation and modeling and (2) systems analysis and integration.

Program Goals

The following are the goals of the Vision 21 Program as defined in presentations to the committee. The objectives of the Vision 21 simulation and modeling activity are as follows:

  • Develop science-based computational tools and apply them to simulate clean, highly efficient energy plants of the future;

  • Develop a virtual simulation capability that predicts:

    • Interactions of turbines, fuel cells, combustors, environmental control systems and other major components;

    • Dynamic responses of an entire energy plant; and

    • A virtual environment in which to visit and explore future Vision 21 plants.

The objectives of the Vision 21 systems analysis activity are as following:

  • Identify and evaluate concepts for Vision 21 plant subsystems and components;

  • Select “reference” plants for detailed study; and

  • Identify technology gaps and an R&D strategy to fill gaps.
