Exploratory Topics
Knoxville, Tennessee
Project Term:
05/28/2020 - 11/27/2022

Critical Need:

This topic seeks to support entrepreneurial energy discoveries, by identifying and supporting disruptive concepts in energy-related technologies within small businesses and collaborations with universities and national labs. These projects have the potential for large-scale impact, and if successful could create new paradigms in energy technology with the potential to achieve significant reductions in U.S. energy consumption, energy-related imports, or energy-related emissions. These specific projects address technology areas across ARPA-E’s mission spaces, with particular focus on: Advanced bioreactors; Approaches and tools to create enhanced geothermal systems; Non-evaporative dehydration and drying technologies; Approaches to significantly enhance the rate and/or potential scale of carbon mineralization; Separation of CO2 from ambient air (direct air capture); High-rate separation of dissolved inorganic carbon from the ocean to produce a CO2 stream; Advanced trees and other engineered biological systems for carbon sequestration; Innovative deep ocean collector designs for mining polymetallic nodules; Environmental sensors capable of operation in deep ocean environments for mining polymetallic nodules; and Non-carbothermic smelting technologies. Awards under this topic are working to support research and establish potential new areas for technology development, while providing ARPA-E with information that could lead to new focused funding programs. The focus of these projects is to support exploratory research to establish viability, proof-of-concept demonstration for new energy technology, and/or modeling and simulation efforts to guide development for new energy technologies.

Project Innovation + Advantages:

Direct contact ultrasonic drying is a novel, non-evaporative dewatering process that uses no heat to significantly lower the energy required for industrial drying. The technology mechanically removes water by shaking the object rapidly, on the micron scale, using piezoelectric transducers. The technology can achieve 5X higher efficiency and 2-3X faster drying rates than traditional dryers on typical textiles. UTS will develop and demonstrate a proof of concept prototype expanding the technology’s application from a batch into a continuous process, enabling easy integration into roll to roll manufacturing production lines. The technology could have wide application in the textile, pulp and paper, chemical, carbon fiber, and food industries.
