prevent salt freezing during high-wind drain-and-fill operations. More reliable, cost-effective valves and instruments must be proven for use in molten salt. Also, plant designs must be simplified to reduce values, instruments, and O&M costs. For example, long-shafted pumps mounted directly on the storage tanks eliminate pump sumps and valves and reduce failure modes. Likewise, the elimination of the outlet vessel and valves from the downcomer (outlet) piping reduces complexity and cost. These concepts need to be tested further. Higher receiver flux levels reduce the receiver’s required size and cost, while simultaneously increasing efficiency. Additional analysis and testing of receivers will be required, as will improved heliostat accuracy, flux monitoring, and feedback systems. Increased annual receiver absorptivity will reduce LEC and can be achieved by both increasing the as-new absorptivity and increasing durability. In the long term, operating temperatures of 600o–650oC will be required if higher efficiency, supercritical Rankine cycles are used. “Solar salt” has been kept stable at 650oC in prototype testing. In the next 5 years, work is needed on salt stability, containment materials, and receiver designs to determine if this approach is worth pursuing. If successful, additional development and testing would be required to prove the concept at larger scale. III. Developing higher-efficiency power cycles and improving balance-of-plant technologies. Molten-salt power tower plants use commercial Rankine-cycle steam turbines to generate electricity. However, additional work is needed to improve O&M procedures, refine plant controls, and reduce parasitic losses. Some markets may have water-supply constraints, so lower-consumption dry or hybrid wet/dry cooling technologies will be needed. The power industry is developing large, high- efficiency, supercritical Rankine cycles for use with conventional fuels. Work is needed to evaluate the use of increased operating temperature power-tower technology with these cycles. IV. Performing system integration and analysis. The design of a power-tower plant is a complex optimization involving the size, cost, and performance of the many subsystems. Optimal designs provide lower energy costs, and updated design tools are needed to achieve this potential. Also needed is an integrated analysis tool that simplifies case studies and additional work in assessing market issues, such as the value of storage or impact of public policy, and identifies market-entry opportunities. Improved solar resource data are needed for performance predictions in potential markets. Support of industry in deploying commercial projects is critical and offers very high return on investment, because significant reductions in LEC are projected from the rapidly increasing scale (size) of the initial commercial deployments.
