Announcement from the Department of Energy's Water Energy Tech Team, November 17, 2016.

WASHINGTON - The Department of Energy (DOE) has been continuously engaged in the energy-water nexus since issuing The Water-Energy Nexus: Challenge and Opportunities in 2014. This factsheet contains a selection of patents from DOE’s National Laboratories that align with the energy-water initiative and have high potential for commercialization. A subset of these patents is eligible for a licensing discount based on energy and/or water savings under an energy-water licensing agreement developed by the DOE’s National Renewable Energy Laboratory (NREL).

DOE’s laboratories are responsible for the research and development (R&D) of solutions that will help to resolve water security issues. The labs examine innovative, highly-effective and accessible techniques for removing unsafe elements like arsenic from water, and accelerating groundwater and wastewater cleanup through the use of agriculture oils. Through the development of various advanced treatment techniques, such as using naturally occurring microalgae to detect the presence of toxic substances, DOE labs are working to ensure the quality of water for use in a multitude of ways.

The NREL ENERGY License is designed to incentivize large-scale deployment of energy and water technologies by allowing licensees to deduct a portion of fuel, electricity and water offsets against a portion of the royalty obligation owed to NREL or other national laboratory licensors offering this license option.
