The Spirit of AdventureEstablished guidelines and criteria
EO13423/13514, EISA 2007, EPACT 2005, Doctrine End Goals 30% reduction in Consumption 1.5% increase per year in renewable energy (25% by 2025) 15% increase in high performance buildings 30% reduction in water consumption 100% of new facilities to be net zero by 2030 20% reduction of petroleum use by 2015
Decisions to be made Control of the Program Drawing the Box around your ProgramWorking with others
Create a baseline
– “Wow, that’s a large undertaking.”

I have just met you, and I love you….Air Force Three Phase Approach
Reasons behind it Past experience Industry concerns
Phase 1 – Resource Availability Desktop evaluation Purely potential Logic Gates
– Incentives– Cost of Electricity– Resource Potential– Usage/Load
Narrow the field
Phase 2 – Technology Feasibility Site visits Resource Verification Environmental Land Use Restrictions Potential Showstoppers Small scale economics
Phase 3 – Business Case Analysis Cash Flow Profitability 30% Design

I’ve altered him…He can protect you nowSolar Energy – Net-Zero Case Study
Tucson Air Nation Guard Base (ANGB) – Tucson, AZ – Home of 162nd Fighter Wing – Adjacent to Tucson International Airport Scope of Work Determine existing renewable energy resource capacity Determine potential for non-renewable energy reduction Determine potential for net-zero application Determine On-base and Off-base options for renewable energy Determine operational impacts (if any) Determine Funding Opportunities/Sources Determine if current infrastructure could support net-zero Determine if base could go “carbon neutral”
Conducted Energy Audit – Determined potential for non-renewable energy reduction to be 39%.

Let’s do this…Let’s Put a Pin in ItKinds of “Net-Zero”
As defined by EO 13514 (Carbon Neutral) Designed, constructed, and operated to require a greatly reduced quantity of energy
to operate, meet the balance of energy needs from sources of energy that do not produce greenhouse gases, and therefore result in no net emissions of greenhouse gases and be economically viable
Based on Usage Mass Balance Equation – Energy in = Energy Out
Based on Demand “Energy Island”
Example – Base needs approximately (on average) of 4MW of continuous load - Equivalent to 35,000,000kWh of energy in a year (let’s say it includes
heating BTUs)– Generate 35,000,000 kWh of energy anytime during the year (Usage)– Generate more to offset commuters, flight operations, etc, etc… (C-N)– Generate 8MW of energy (70bWh), to handle peak demand loads
(summers in AZ, must have AC), sell excess to grid, store, or waste… (Demand)

This is absolutely RidonkulousDifferent Types of Photovoltaic Systems
Surprise: Arizona has a lot of Sun! Photovoltaic Potential for Energy Generation Thin-Film PV - 15% Building-Integrated Roofing PV – 10-15% Crystalline Panels Monocrystalline silicon – 25% Multi-crystalline silicon – 20% Advanced Technologies (Robins AFB – New technology – 38%)
Thermal Wall and Thin-Film PV Water/Glycol/Evacuated Air Thermal Water Heating Day Lighting (Passive and Active) Other Solar – Concentrating

Where is the Green-Eyed Man?Under-Utilized Areas
If it isn’t being used and it has sun on it – Let’s cover it with PV! Storm water Retention Canals Air Field space Erosion Control Method for Ammunition Bunkers Hangar Space and Air Craft Sunshade – Potential for Danger… Parking Lots Rooftops

He is fully awesome!Solar Partnering and Results
Team up with Tucson Airport Authority and Tucson Electric Company Potential to produce over 124% of bases current needs with only land
use on base.

Whole wheat is not the same thing as whole grainSolar Energy at Buckley AFB, CO
Economies of Scale – Design and Build 1.2MW solar field 230 Separate panels – Single axis tilt 5% of total energy needs 6 Acres Not plug and play – Design needed Footings Maintenance Accessibility Grid Interconnection Loading controls

SuperBark!Solar Challenges and Caveats
Expense - $4 – 8/watt Variability of load Efficiency vs Cost Design Historical Consideration The REC question Qualified Installer Safety Disposal

I wanted to give them a little sizzle….Waste to Energy – Kadena AB, Japan
Kadena Air Base, Okinawa Island, Japan Scope of Work Determine viability of Waste to Energy generation on or near Kadena
–Wet process–Dry process–Energetic process
Determine environmental impacts of such processes Additional uses of byproducts Cost Estimates Life Cycle analysis

You got more talent in one lug nut than most cars have in their whole body…Driving Factors
Island of Okinawa has no place to put their trash Political reasons Reducing American Impact Old Battlefields to be reclaimed
15,000 tons of Municiple Solid Waste per year (pop. ~ 55,000) Energy generation, reduction goals Similar technology employed by the Japanese Cost considerations $150/ton for disposal May increase to $425/ton
Waste heat to create steam for: Desalination Chilled Water for base consolidation Heating base facilities

Turn Left to Go RightDiffering Processes
Bio-Digestion Limited Fuel availability – Chow Hall Municipal Wastewater system
Incineration Reduced Fuel availability Stack requirements Can desalinate sea water
Plasma Gasification Full waste reduction Potential Untried Technology Energy Intensive Start-up
Pyrolysis Fuel Production

If anyone asks, we were out smashing mailboxes all nightEnvironmental Impacts
New Municipal Waste Combustion systems (including plasma) are required to comply with Japanese Environmental Governing Standards (JEGS) which are very similar to the New Source Performance Standards (NSPS) from the USEPA Drinking water could be generated on base Potential to destroy HAZWASTE on site Potential to destroy Lead Based Paint on site Potential to destroy asbestos, PCBs, and other

I’m happier than a tornado in a trailer park…Kadena AB Feasibility Results
300 square foot footprint Potential to eliminate waste (10-100%) Potential to create energy (up to 1.6MW) Potential to create fresh water (350gpm) Potential to create steam for heat or adsorption chiller Potential to break even if costs for waste disposal increase

What are you going to do, he’s my best friend…Kadena WTE Challenges and Caveats
Unproven Technology – Plasma Japanese Mainland Canada 52 sites worldwide Hurlburt Field, FL
Political Issues Local Incineration plant Increased Infrastructure Self-sufficiency of military base
Costs Research costs driving initial costs High Maintenance costs Limited expertise Cheap energy/waste disposal costs will highly impact
