1 Addressing urgent expeditionary energy needs using multiple renewable sources, simultaneously, to satisfy the military s gargantuan thirst for fuel and deployable power on the battlefield Presented by: Todd Bullivant, President Steve Lew, Green Systems Manager, M.E. Kyle Tierney, Product Development Specialist, M.E. 1

2 What exactly is the military s gargantuan thirst for fuel and deployable power? 1 Fuel supplied in support of U.S. forces in Iraq and Afghanistan in 2008 : 68 million gallons/month 816 million gallons/year This is enough fuel to power 1,102,702 cars for a year (at an average of 22 miles per gallon) or to fill 1,236 Olympic sized swimming pools! 1 For the purposes of this presentation deployable power refers to power needed to sustain forward deployed locations particularly those not connected to a local power grid. 2

3 What exactly is the military s gargantuan thirst for 1 fuel and deployable power? The cost of fuel supplied in support of U.S. forces in Iraq and Afghanistan : $9.5 billion in Fully burdened costs begin at about $15/gallon A $10 increase in the price of a barrel of oil increases DOD operating costs by $1.3 billion 2 Burdened cost is also referred to as total ownership cost and includes costs associated with buying, moving, and protecting fuel sources. The fully burdened cost of $15/gallon does not include any force protection for supply convoys. Data provided by the OSD Program Analysis and Evaluation office. 3

4 Who and What are the largest fuel consumers? U.S. Army generators consume 357 million gallons of fuel annually during wartime 70% of Army tonnage required to position forces for battle consists of fuel and water The single largest battlefield consumer of fuel is generators Source: United States Government Accountability Office (GAO), Report to the Subcommittee on Readiness, Committee on Armed Services, House of Representatives.

5 What is the end consumption point? The generator? The GAO stated that The single largest battlefield consumer of fuel is generators But, is your home the largest consumer of electricity? 5

6 The end consumption point, or fuel consumer, is not the military generator It is the air conditioner, heating, lighting, refrigeration, and 3 communications equipment used by the U.S. military at forwarddeployed locations in that order.

7 Not too dissimilar from the air conditioning, heating, lighting, and electronics in your home. You buy energy efficient appliances to reduce your electric consumption. 7

8 It is the military s air conditioning, heating, lighting, refrigeration, and communications equipment consuming the fuel! A USMC Energy Audit in Afghanistan estimated that 75% of generator demand was for heating and air conditioning A/C Demand 8

9 Energy efficiency is a supply and demand equation Addressing the supply, or power generation side, by introducing solar/wind power solutions to the battlefield, is only half of the equation. Attention must be paid to the demand, or consumption side, to truly reduce military fuel consumption in a meaningful way. 9

10 Energy efficiency is a supply and demand equation (X)S-(Y)D=W S= Power Supply (kilowatts) D= Power Demand (kilowatts) X= Generator Maximum Continuous Watt Rating (i.e., 10kW) Y= Generator load (kilowatts) W= Wasted Energy (kilowatts) Since Y is often unknown and dynamic in nature W is often higher than it needs to be. At equilibrium W = 0 10S-6.5D = 3.5W 10

11 When the supply and demand side are both considered as part of the equation, then and only then, will we truly realize the many benefits of renewable energy on the battlefield. 11

12 The many benefits of renewable energy on the battlefield: 1. Reduced fuel consumption: 50% or more 2. Reduced fuel costs: 50% or more 3. Less noise silent watch capabilities 4. Less maintenance less generator run time 5. Heat signature reduction 6. Self sustaining - abundant, free, renewable power source 7. Less environmental impact- carbon emissions/pollution 8. Fewer fuel trucks in convoys 9. Less casualties related to resupply convoys 12

13 Energy Efficiency is a Supply and Demand Equation To date, efforts to reduce fuel consumption have primarily focused on one side or the other of the equation: Supply: Solar and wind expeditionary power generators 13

14 Energy Efficiency is a Supply and Demand Equation To date, efforts to reduce fuel consumption have primarily focused on one side or the other of the equation: Demand/Consumption: Energy efficient foam insulated tents the tent foaming initiative could reduce energy consumption by approximately 50 percent GAO, February

15 Energy Philosophy 101 Socrates When Supply and Demand are the same, a state of equilibrium is said to exist. When energy supplied equals energy demanded a state of perfect efficiency is achieved. This is only a theoretical possibility. How do you supply power in direct proportion to demand? Anything supplied above the existing demand level represents inefficiency or wasted fuel. How much of the 816 million gallons of fuel was used to run generators that were not under full load? 15

16 Getting Closer to the Perfect State of Energy Efficiency A holistic approach, or one that considers supply and demand, to renewable energy brings the supply and demand equation closer to equilibrium. Supply A deployable power source that harvests solar and wind resources and has a finite storage capacity 12kW Capacity = = = Demand Matched with insulated, containerized housing unit/s (CHUs) prewired with super efficient air conditioning, heating, lighting, and refrigeration and a known maximum energy demand 3kW demand x (4) CHUs = 12kW Demand The generator now balances the equation by supplying power only when renewable sources are not at 100% of capacity 16

17 A Case Study: Getting Closer to the Perfect State of Energy Efficiency Several deployable water filtration systems were needed in Africa to support USMC operations there. An off grid power solution was requested. 17

18 A Case Study The Demand or Consumption side was addressed first: A highly efficient, readily deployable, water filtration system was designed to meet USMC mission requirements. 4 GPM. All motors, pumps, and purifiers were sized for the requirement and are sequenced so that start up amperage or spikes are limited to one motor or pump at a time. This greatly reduces peak wattage demands and greatly reduces overall power requirements. Existing systems required 100+ amps to operate, this one required only 25 continuous amps. 18

19 A Case Study Next, the Supply or Power side was addressed: A renewable energy power center was provided which harvests solar, wind, and hydroelectric resources simultaneously and stores the energy in a battery bank. The DC power is converted to AC by way of a hardened inverter and enough power capacity exists to run multiple water filtration systems simultaneously. If renewable sources ever fall short, the existing military 10kW, 60hz genset starts automatically and makes up the power deficit. 19

21 Renewable Energy Power Systems: Demand / Consumption Side of the Equation Super efficient, field refrigeration units Expeditionary vehicle wash and decontamination units Containerized Housing Units (CHUs) with integrated, super efficient A/C, heating, lighting and appliances. Energy efficient, containerized batch laundry units 21

22 The challenge for all of us is to find ways to balance the supply of energy with the demand or consumption of that energy. A good first step is to look at what we are plugging into our generators and ask ourselves if there s a better, more energy efficient way to do this. The reward for doing so is the substantial reduction of JP-8 fuel consumption, billions of dollars in fuel cost savings, and most importantly a reduction in warfighter casualties. Thank You 22
