The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is in demonstrating the commercial implementation of NBD Nanotechnologies, Inc.'s (NBD) Enhanced Condensation Coating. NBD's external surface coating sustains dropwise condensation on copper-based tubes, resulting in energy savings and increased efficiency for industrial condensers in steam power and thermal desalination plants. NBD's innovative and proprietary techniques ensure adhesion onto the substrate while not compromising the thermal resistance with the coating's sub-microscale thickness. NBD has validated the increased efficiency of its external surface condenser coating technology at a lab-scale and will carry out pilot tests to quantify the efficiency gain and technology durability at a system-level in industrial condensers, as requested by utility customers. NBD presents a technology that addresses the key commercial bottlenecks of durability, scalability and performance, which have stymied coatings in condensers, presenting a leapfrogging technology that addresses the water-energy nexus. Every 1% improvement in power plant efficiency results in $10MM revenue per plant per year, as stated by a partnering power generation company. Thus, any improvement in the efficiency of a steam condenser has significant impact that directly benefits both global energy and water sustainability efforts. This project contributes to R&D advancement focused on: large-scale chemical and coating processing, surface wettability, nano-and micro-scale heat transfer, condensation, and water and energy resource sustainability. The project's multidisciplinary nature reflects the dynamic aspects of condensation heat transfer phenomenon, which covers varying length scales (nano, micro, meso and macro scale) and time scales. Thus, the challenging nature of optimizing and sustaining enhanced condensation invites innovative and creative solutions to mitigate the water and energy resource management problems. During Phase I, the project demonstrated the proof of concept of the coating's condensation enhancement for both industrial condensers with pure steam (and trace amounts of non-condensable gases) and for HVAC/dehumidification systems where condensation occurs with higher concentrations of non-condensable gases. The objective of phase II proposal is to address and facilitate the required steps for scaling up and integrating NBD's condenser coating into industrial condensers' supply chain. NBD has identified industrial condensers as its primary entry market, where a greater increase in condenser system performance and savings in cost and fuel consumption can be reached. NBD has been establishing partnerships for pilot studies to perform larger scale experimental tests to validate its technology's performance, durability and system-level efficiency gains empirically.

Fog harvesting from fog nets has been intensively investigated to utilize untapped fresh water resources. Atmospheric water like fog constitutes approximately 0.04% of the earth's fresh water. If fog is harnessed appropriately, it has a huge potential to alleviate fresh water shortages due to depleting watershed and groundwater resources NBD Nanotechnologies, Inc. is proposing a research program to commercialize a proprietary surface coating for fog net applications to exploit underused fresh water resources in fog-laden areas. The proposed coating consists of a proprietary blend of superhydrophobic coatings to which NBD has exclusive licensing rights, and uses a one-step dip process that is very amenable for mass-manufacturing and scale up. Also, an embedded drainage design and multi-layered fog nets can promote significant enhancement of water collection from the fog nets. During USDA SBIR Phase I, NBD has shown that by modifying the surface texture and chemistry of a fog net with a superhydrophobic coating, and optimizing the mesh structure, the fog collection efficiency of a system can be enhanced five-fold.Fog nets with enhanced water collection efficiency would provide an ecofriendly and low-cost solution towards reducing the strain on the fresh water supplies in drought-affected areas as well as providing an effective method of delivering water for onsite crop irrigation. If successfully implemented on a commercial scale, the enhanced fog harvesting abilities of the proposed fog nets will reduce the strain on watershed resources in drought afflicted regions, and provide a valuable source of fresh water in isolated rural communities.
