Funding for the Vision 21 Program comes from existing product lines in the R&D budget of the Coal and Power Systems Program. These product lines include integrated-gasification combined-cycle systems (IGCCs), turbines, advanced combustion, fuel cells, indirectly fired cycles (IFCs), fuels, and other advanced research. The program budget for "Vision 21" activities in all of these product lines amounted to about $14 million in FY98 and $18 million in FY99. Most activities associated with Vision 21 have been on IGCCs. Future work will focus on critical modules, such as high-efficiency bottoming cycles, air (oxygen) and syngas (hydrogen) separation membranes, multiple feedstock turbines, the integration of fuel cells and turbines, the development of virtual demonstrations, advanced combustion, ultra-high-temperature materials, and the synthesis of clean fuels.
In OFE's budget for FY00, approximately $29 million is focused on Vision 21 activities. Vision 21 does not yet have a budget, however. It represents a shift in objectives within OFE, not new line items in the OFE budget. In future years, funding for Vision 21 activities is expected to increase and eventually surpass the budget for central power plant energy generation. The other parts of the Coal and Power Systems Program (i.e., distributed power, innovations for existing power plants, carbon sequestration, fuels, and other projects) are expected to continue to receive funding outside of the Vision 21 Program.
Vision 21 is described by DOE as a program for the development of integrated concepts for high-efficiency power generation and pollution control from a new class of fossil-fueled facilities capable of coproducing electric power, process heat, and high-value fuels and chemicals. The major goals of the program are elaborated in Table 2-1.
The focus of the program will be on flexible components and subsystems to enable modular designs for plants that can use multiple feedstocks or produce multiple products. To establish a blueprint, DOE plans to focus Vision 21 on several elements that will be common to all of the facilities under consideration:
Enabling technologies, such as flexible-fuel gasification, flexible-fuel turbines, fuel cells, advanced combustion and high-temperature heat exchangers, will be the building blocks of twenty-first century energy plants.
Supporting technologies for crosscutting technologies, such as controls and sensors, new materials, advanced computational modeling, and virtual
