Vision 21: A Quest for the Ultimate Energy
What is Vision 21?
In the following paragraphs Patricia Fry Godley
of the Department of Energy answers this question:
21" is more than a name. It is a strategic concept that will
tie together, and guide, much of our current and future R&D
basically challenges the coal R&D community with the question
"Can you develop the ultimate coal facility?" Not simply
the "next generation" facility?....but the ULTIMATE
facility. And not just the ultimate "POWER plant"...but
the ultimate ENERGY facility -- where every useable BTU in coal
or biomass, or perhaps a fuel mix, is extracted and used: for
electricity, process heat, fuels, chemicals, or combinations.
That's why we add the term "EnergyPlex."
21" is not so much a "new start" as it is a new
way of thinking about our existing technologies....and working
to tie them together in the most flexible way in the future.
we develop the "Vision 21" way-of-thinking, we are asking
the technical community, "is a zero-discharge energy facility
possible?" Virtually no SOx or NOx pollutants. No particulates.
No wastewater. No solid waste. And the potential for no net emissions
of CO2. In other words, no impact on the environment outside of
the plant's basic footprint. Is that possible?
the combined Government-industry efforts, and the work of the
best and brightest scientists in the Nation -- we think it is.
We think we can develop a coal-based energy facility that's
60% efficient or, with cogeneration, perhaps 80 or 90% efficient.

Reaction Engineering's Vision21 Project
In our DOE Vision 21 project, Reaction Engineering
International (REI) is developing a computational workbench that
will provide a framework for integrating the range of models and
visualization methods that will be required to perform simulations
to predict energyplex performance and emissions. The workbench
is being developed as a tightly integrated problem solving environment,
with plug and play functionality, that contains an array of tools
and models that communicate in a seamless manner. The workbench
is designed for use by the non-specialist and provides the capability
to interrogate a simulation at multiple levels of detail. The
models contained in the workbench can range in complexity from
simple heat/mass balance models to sophisticated CFD based models.
Through the course of this program, models have been created for
simulating key energy plant components, including boilers, gasifiers,
fluidized beds, combustors, fuel cells and clean-up process components.
Some of these models tax the limits of the computer power readily
available to most engineers.
Problem Solving Environment
The workbench is being constructed using the SCIRun
software system. SCIRun is a continuously evolving product of
the Scientific and Computational Imaging group, headed by Prof.
Chris Johnson, in the Department of Computer Science at the University
of Utah (UU/SCI).
From inception, SCIRun has been designed in an object-oriented
manner with the intent of supporting interdisciplinary projects
in which High Performance Computing (HPC) models are needed. SCIRun
places no inherent limitations on the physics, numerical technique
or programming language used within a model. SCIRun supports component-based
software techniques and allows for distributed computing. In addition
to these capabilities, SCIRun also includes sophisticated scientific
Vision 21 Workbench in action. (Large)
For the comprehensive models included in the workbench
which calculate three-dimensional scalar and vector fields, the
workbench provides a number of options to visualize these data
sets. First, the data can be visualized using the inherent capabilities
of SCIRun. Second, the data can be viewed using OpenDX, which
we have coupled directly to the workbench. Third, the data can
be viewed using a VTK-based toolset, which again has been tightly
integrated with the workbench. For Virtual Reality visualization
on a range of display hardware, we are currently integrating the
capabilities of Iowa State University's VRAC Explorer. Additional
information on these various visualization techniques and packages
can be found here.
