The commercial availability and long-term survivability of materials is considered a critical area for all advanced power-generation technologies, regardless of fuel source. Of course, resolving materials-related problems and issues is much more challenging for coal-based technologies. Numerous technology configurations are possible for Vision 21 systems, as well as for future electric power-generation options using coal as feedstock, and each option presents different materials problems. Therefore, the R&D materials projects, including commercial deployment, should be closely coordinated.

Currently, new materials (both alloys and ceramics) suitable for use at high temperatures in corrosive and erosive environments are being developed as part of DOE’s Base Technology Program, as well as by the Vision 21 Program (Judkins, 1999). R&D is carried out mostly at Oak Ridge National Laboratory (ORNL) and is being monitored by one FETC associate for its applicability to the Vision 21 Program.

DOE’s overall research program on advanced materials and heat exchangers includes the following areas:

• new classes of materials for high-temperature alloys, ceramics, and intermetallics

• testing and demonstration of materials for advanced, high-temperature heat exchangers

• development of high-temperature filter materials

• development and testing of high-temperature materials for refractories, sensors, and the production of advanced fuels

• development of new gas-separation membranes

• development of advanced composite materials

• development of oxide-dispersion strengthening (ODS) materials and production technologies

• development of catalytic materials for gas purification
