The National Alliance for Water Innovation (NAWI) hub, funded by the U.S. Department of Energy (DOE), recently announced its intent to issue a Request for Proposals (RFP) for innovations in intensified brine management solutions for high salinity streams. The RFP supports the Water Security Grand Challenge (WSGC), a White House-initiated, DOE-led framework to advance transformational technology and innovation to meet the global need for safe, secure, and affordable water using a coordinated suite of prizes, competitions, R&D, and other programs.

“I’m excited about our efforts to accelerate innovation in advanced water treatment technologies, which will strengthen America’s water security,” said Daniel R Simmons, Assistant Secretary of Energy Efficiency and Renewable Energy. “These efforts will help sustain American leadership in energy and water innovation.”

Water is a critical resource for human health, economic growth, and agricultural productivity. The United States has historically benefitted from access to low-cost water supplies, but changes to freshwater supplies could threaten American economic competitiveness and water security. To address this challenge, NAWI is focused on developing energy-efficient and cost-competitive desalination technologies from non-traditional sources.

The potential RFP contains detailed information about NAWI’s current assessment of early-stage applied research needs for brine management. It will focus on five areas: the thermodynamics and kinetics of inorganic scaling; heat and mass transfer optimization; process and material innovations; low-cost, small-volume salt crystallizers; and techno-economic analysis of novel brine waste valorization.

Prospective applicants are strongly encouraged to consider cost share partnerships. NAWI plans to award 4-12 projects to teams of researchers from industry, academia and DOE’s national laboratories, with a minimum 25% cost share required from each team. NAWI plans to issue the RFP in August 2020.

NAWI is currently developing five R&D “roadmaps” (Power, Resource Extraction, Industrial, Municipal and Agriculture) for nine source waters (industrial, municipal, brackish groundwater, conventional produced water, unconventional produced water, agriculture, mining, power and seawater) to inform future RFPs.
