Sandia National Laboratories is a multi-program laboratory operated and managed by
Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for
the U.S. Department of Energy's National Nuclear Security Administration under
contract DE-AC04-94AL85000. SAND2010-6484C
Essence of the Energy~Water Nexus
Water Challenge – The combination of population growth and climatic variability
are leading to major competition and conflict over freshwater availability, both
in the United States and multiple strategic world regions.
Energy Challenge – Energy and water are increasingly interdependent
because electric power generation requires very large quantities of
water; future power demands for supplying society’s water needs will
grow substantially.
Science Opportunity – The Nation’s challenges at the nexus of energy
and water require new discoveries and advances in our scientific
understanding and tools. These include new membranes and
separation processes, interaction of surfaces and frictionless
materials, advanced simulation and prediction of regional water
availability and demands, revolutionary process measurement and
monitoring methods, and science-based management of integrated
energy-water systems.
Energy~Water Nexus Initiative Meeting Challenges to Energy and Water Security

Created by NETL, LANL, SNL in August 2001
• Held topical workshops in Denver (June
2002)and Pittsburgh (July 2002)
Expanded to include 12 National Labs
• LERDWG February 2003 : EWN Team formed
(11 Labs)
• SRNL involved starting August 2005
Problem Definition, Planning
• 2003-Present: Team-generated strategy, white
papers, presentation materials, website

Summary of Major National Needs and
Research Directions from Roadmap Workshops
1. Integrated regional energy and water resource planning and
decision support tools
2. Improving fresh water use efficiency in thermoelectric
power generation
3. Accelerate implementation of renewable and fresh water
use efficient power generation resources
4. Improve water use efficiency in biofuels/biomass energy
5. Assess use of nontraditional water for energy production
and generation
6. Improve water treatment to reduce water quality concerns
on oil and gas development - produced water, oil shale, etc.
7. Improve characterization/monitoring of water supplies,
trends in supply variability, and changing demands
8. Infrastructure changes to improve energy/water efficiency

Water-Energy Research Needs

R&D to:

reduce steam power plant cooling requirements
 Nuclear, fossil, concentrating solar

reduce energy requirements of desalination

develop less energy-intensive technology for water
decontamination, treatment and reuse

reduce water use in agriculture
7
Research Needs
(continued)

understand the water requirements of emerging
energy technologies:
 biofuels
 carbon capture and sequestration
 oil and gas shales
 tar sands
 hydrogen economy

understand the impact of global climate change on
spatial and temporal variability of water resources
8
DOE Water-Energy R&D Activities

Several program offices are supporting water-energy R&D
 Energy Efficiency & Renewable Energy, Fossil Energy,
Policy and International Affairs, Nuclear Energy, Science

Many national laboratories and contractors are
carrying out these R&D activities

These efforts will receive increased emphasis in the future
as the US and other countries undertake efforts to adapt to
the impacts of climate change
 an initial report to the President by the interagency
Climate Change Adaptation Task Force is scheduled for
October
9
A Sampling of DOE R&D Activities

minimizing the environmental impact of water used for the
hydrofracturing of gas shales

reducing water used by biofuels, nuclear, geothermal and
concentrating solar power systems

detecting, understanding and predicting climate change
impacts on precipitation

opportunities for hydropower upgrades at existing facilities

analytical tools for managing energy-water tradeoffs in
hydropower systems

impacts of drought on water availability for power plant
cooling in Western U.S.
10
DOE R&D Activities
(continued)

advanced, more efficient separation technologies for
treating degraded water

improving the quality of oil and gas produced water

addition of water flows to energy planning models

use of mine water and treated wastewaters in thermal
power plants

use of saline formations for combined thermal power plant
water needs and carbon sequestration

water-related issues affecting conventional oil and gas
recovery and potential shale oil development in Utah
11
Concluding Remarks

In recent years there has been a growing understanding
and acknowledgment that water and energy issues are
inseparable

A broad range of water-energy R&D activities currently
is supported by the U.S. Department of Energy and
the level of support is likely to increase
