Energy-Water Nexus and Site Resilience

Office of the Deputy Assistant Secretary of Defense for Installation EnergyAugust 16, 2017


What is the Energy-Water Nexus ?

• Water and energy systems are interdependent• Water is used in all phases of energy production

and electricity generation – Providing cooling to power plants– Irrigating crops for biofuels– Energy production and electricity

• Energy is used to extract, treat, convey, and deliver water and to treat wastewater

Despite their interdependency, energy and water systems have been developed, managed, and regulated independently.

Department of Navy (DON) - Water Energy Nexus (WEN) Project Development in the Southwest (SW)

Andrew Baughman, PENavy Facilities Engineering Command Southwest

August 18, 2017


Energy production requires water and land:• Thermoelectric cooling• Hydropower• Extraction and mining• Fuel Production (H2,

ethanol, biofuels)• Emission controls

Water production anddistribution require energy and land:• Pumping• Treatment• Transportation• Heating

Land-use activities (e.g., agriculture) require energy and water:• Irrigation• Processing• Transportation

Energy-Water Opportunities to Improve Operational Resiliency

• What is a microgrid?– A microgrid is a local energy grid with control

capability, which means it can disconnect from the traditional grid and operate autonomously.1

• Energy-water microgrids incorporate the design and operation of energy and water systems in a coordinated framework.– Provide an abundance of benefits in the context of

resiliency.

Microgrids

https://energy.gov/articles/how-microgrids-work


• How can energy-water microgrids be designed, operated, and deployed in a variety of different locations to improve the resilience and efficiencies of food, energy, and water infrastructure?

• What are the opportunities and limitations to microgrid adaptation in response to food, energy, and water resource uncertainty at multiple time-scales?

• What is the value of adding resilience to our energy-water systems?

26

Energy-water microgrids


• Traditional water reduction opportunities– Reducing irrigation water use, identifying leaks, decreasing

domestic water use• Investigate largest water consumers and consider critical

loads and applications– Cooling towers– Irrigation– Fire suppression– Data centers– Water pumping

• What happens to these loads and to operations if the electrical grid goes down? Or if water supply isn’t available?

• Consider water supply and potential for adding redundancy and increasing reliability.

27

Energy-water opportunities


Biosphere 2 example

• 3.14 acre Biosphere on 40 acre site • 7 model ecosystems• Active research facility• Commercial, residential, industrial

components• Energy:

• Grid-connected (4 feeds)• Reliability concerns

• Occupant comfort, biome temperatures and humidity, and research activities drive energy usage

• Water:• Groundwater supplied (currently)

• No cost for water• Numerous water storage tanks• On-site wastewater treatment system

augmented by septic system• Energy-water interdependencies

28


Energy and water system interactions

• Cooling towers represent largest water consuming energy system at B2

• Pumping from wells• Ocean infrastructure (heating and movement)• Biome requirements (raining)• Water treatment• Water heating• Chillers

Energy requirements for waterWater requirements for energy

Annual Well Electricity Usage (2007-2016)Annual Cooling Tower Makeup Water (2007-2016)

29


• Traditional energy efficiency and water efficiency opportunities

• Shifting water pumping to night time• Adding pumped hydro to water storage

system• Adding RE systems to help with electrical

reliability issues• Adding RE and batteries at pumps• Investigate co-location of PV and agriculture
