Milestones4

Approach9 Procure turn-key H2 fueling station designed foreasy expansion9 Use fuel cell PHEVs to maximize the efficiency of anew park shuttle bus service at Hawaii VolcanoesNational Park.9 Collaborate with existing data analysis groups tocompare system data under different operatingconditions (fueling station & vehicles).9 Evaluate the effect of different grades, climaticzones, air quality conditions including SO2 onvehicle performance.9 Identify areas that require further technicaldevelopment such as air filtration systems.9 Transfer results to industry and governmentagencies5

Hawaii Hydrogen Power ParkPower Park to provide hydrogeninfrastructure to support hydrogen shuttlebus program at Hawaii Volcanoes NationalPark6

Hawaii Volcanoes National Park9 Power Park supports NPS “Climate Friendly Parks”program to reduce carbon footprint & improve visitorexperience.¾¾¾¾Reduce traffic congestion- cars and busesReduce size of buses in the parkReduce emissions pollutionReduce noise pollution9 Evaluate performance of plug-in hybrid electric vehicle(PHEV) shuttle buses using hydrogen9 Test bed for range of NPS transportation solutions7

Education & Outreach9 Over 2 million park visitors annually.Hawaii’s biggest tourist attraction.9 HAVO has facilities & team of tour guidesdedicated to public outreach.9 Visitor Center theater and interpretationcenter will host static displays & movie9 Theater to be powered by 5 kW stationaryfuel cell9 Park interpreters on shuttle buses toincorporate hydrogen outreach intopresentations.8

Power Park Hydrogen Fueling Station9 Hydrogen production using electrolysis9 Electrolyzer powered by renewableelectricity from HELCO at special researchrate.9 Fueling station sited at Kilauea Military Camp¾ DOD recreational facility located within HAVO¾ KMC to provide shuttle bus operators to supportproject9 Initial installation to produce 10-20 kg ofhydrogen per day @ 350 Bar with flexibilityto expand

Fueling Station RFP9 RFP for station released March 31, 20099 Station to be supplied on a “turn-key” basisincluding production, compression, storage& dispenser9 Compressor, storage & dispenser sized tosupport increased production capacity.9 Station projected to be operational by Dec 099 Station to be co-located with EV rechargingstation10

Vehicle SupplyUsed with permission of Proterrra9 Vehicle funding obtained by NPS fromAdvanced Transportation for Parks and PublicLands program (ATPPL).9 Hawaii Center for Advanced TransportationTechnology (HCATT) supporting conversion ofshuttle buses9 Leverages Hickam Air Force Base hydrogenvehicle programs9 Options for purpose-built Proterra vehicleunder consideration11

Partner Roles999999999US DOE – program leadership & fundingHNEI – Program management & implementationState of Hawaii – cost share & policy supportHAVO & National Park Service¾ Host site.¾ Vehicle funding¾ Education & public outreach.Hawaii Electric Light Company (HELCO) – supply ofrenewable electricity.Kilauea Military Camp (DOD)¾ Host fueling infrastructure & provide bus operatorsHCATT – vehicle conversion & technical supportPuna Geothermal Venture – geothermal power (pending)ONR – FROG Buildings, supplemental funding (pending)13

Accomplishments/Progress/Results9 Signed implementation agreement with State of Hawaii(DOE funds via State Energy Office).9 Secured State of Hawaii 1.2 million cost share funds viaKolohala Holdings LLP9 Completed hydrogen station specification9 Issued RFP for supply of “turn-key” fueling station9 Developed energy supply agreements – HELCO, PGV,PUC9 Obtained KMC approval and support as site of fuelingstation9 Progressed permitting and NEPA documentation9 Completed noise survey at KMC site9 Assisted HAVO to secure bus funding ( 1 million)9 Continue to work with HAVO on project development14

Future Work9 Select supplier for fueling station – May 20099 Complete site prep for station – Fall 20099 Install fueling station – target Dec 20099 Complete vehicle conversions – target Jan 20109 Operate buses – Feb 2010 to Jan 20129 Collect and analyze fueling station & vehicle data9 Seek opportunities for expansion of fleet and/oradditional hydrogen infrastructure15
