Advanced, High Efficiency Heat Transfer Technologies for Industrial or Utility Applications

Description:

Despite their higher cost and larger system size, dry cooling systems are currently the only alternative for industrial or utility power plants unable to obtain permits for cooling water. Because of this, lower cost highly efficient advanced large scale heat transfer technologies that eliminate the need for cooling water would find a market with industrial and utility plants in areas with competing demands on water from agriculture and development. Promising heat transfer technologies in other analogous industries increase the effective surface area and thus the transfer efficiency. They include nano-textured surfaces, micro-grooved surfaces, ablation, coatings, self-similar geometric modifications, fractal fins, fluidic interface treatments, micro-structural modifications to cooling surfaces, or chemical compositions. Validated simulation or mathematical modeling must show reliable operation above 1.8 GWt and at temperatures and pressures associated with an ultra supercritical steam plant. Proposals must show at least a twenty-five percent cost advantage using annualized levelized cost of electricity (LCOE) per megawatt*hour relative to any commercially available dry cooling baseline. Selection criteria will be cost of implementation, effectiveness as determined by water loss avoidance relative to evaporative baseline, heat dissipation, and uptime.
