Energy-Water Nexus: Why Now? Why DOE?
• Energy and water are interdependent.• Water scarcity, variability, and uncertainty are
becoming more prominent.• This is leading to vulnerabilities of the U.S.
energy system.• We cannot assume the future is like the past in
terms of climate, technology, and the evolving decision landscape.
• Replacing aging infrastructure brings an opportunity to make some changes.
• DOE has strong expertise in technology, modeling, analysis, and data and can contribute to understanding the issues and pursuing solutions across the entire nexus.

Sacrificial Protective Coating Materials that can be Regenerated In-Situ to Enable High Performance Membranes (EERE)
Project Prime: Teledyne Scientific & ImagingProject Partners: Agenda 2020 Technology Alliance, MeadWestvaco Corporation
Technology: Develop and validate a novel membrane technology incorporating an easily regenerated, fouling resistant protective coating that provides an energy-efficient method to concentrate weak black liquor (WBL), a by-product of wood pulp production in the pulp and paper industry. The concentrated liquor is burned in a recovery boiler providing some energy recovery for industry processes.
Technology Update• Developed coating process that enables preferential
formation of intermediates that are polymerized later to minimize particle formation and pore clogging.
• Demonstrated coatings survive process temperature (>85°C) and chemistry (pH of 13 – 14).
• Demonstrated black liquor treatment process (>85°C) for >3 days with <20% drop in total flux.
• Demonstrated coating is superior at concentrating WBL under highly fouling conditions compared to uncoated membranes.
Both membrane surface and inner pore walls are coated without affecting WBL flux. Courtesy of Teledyne.

Informing Hydropower Investment and Operational Decisions in the Face of a Changing Climate (Lab: PNNL)Project start: FY17 – In FY16 the Hydro program held a lab call to initiate research into IAV/IAM models for basin level hydropower and thermoelectric generation. The call was titled "Integrated Climate Risk Modelling to Understand Impacts to Riverine temperature regimes, River Ecology, Hydropower, and Thermoelectric Generation“
Overview:• Project objectives (1) to improve capabilities and modeling tools to assess different
long-term climate risks to hydropower systems and integrated water infrastructure. (2) To provide decision makers with the capability to predict the probable location, timing, duration, and severity of water-temperature events that exceed legal standards and explore alternative operations and infrastructure investments to mitigate the frequency and duration of such events.
• This work is scoped to feed directly into a future 9505 report. • Modelling framework will be developed through a set of interrelated components:
(1) stakeholder engagement, (2) climate modelling, (3) watershed hydrologic modelling, (4) river and reservoir quality modelling, (5) environmental impact assessments, (6) and future hydropower developments.
• Next Steps: Forming National and Basin level advisory committees. Submitted request for climate model runs. Starting important stakeholder outreach and engagement planning.

• Public database of 1700+ state-level water policies that affect energy systems• Types of policies include:
– Water rights – Water discharge regulations– Underground Injection Control (UIC)– State water plans– Regional watershed commissions– Reservoir and river operations – Integrated energy-water policies
• Potential uses:– Policy analysis– Modeling inputs– Visualizations (e.g., interactive maps,
influence diagrams, interstate policy comparisons)
• The database is currently in a “beta” version. We plan to circulate for stakeholder review.
