Why hydrogen?
• Excellent energy carrier• Nonpolluting• Reduced GHGs• Economically competitive• As safe as gasoline • Every region can make its own fuel

Where do we get H2?
Traditional sources
Natural gas, methane, gasoline, nuclear, coal
Renewable sources
Solar, wind, geothermal,
hydro, biomass, algae

Other fuel cell applications
• Transit» Already meet or exceed US DOE
performance and reliability goals» Next focus on cost reduction and full
replacement of conventional fleet
• Medium- and heavy-duty» US DOE development of new FC platforms» Seeking volunteer fleets for demonstrations
• Material handling and lift trucks» Capabilities and cost effectiveness has led to private
company transition without co-funding (Sysco, FedEx, Whole Foods, BMW, etc)

California hydrogen infrastructure goals
• 68 stations –minimum to start the market (CaFCP Roadmap)» Clusters – 45 stations
• Santa Monica and West LA• Torrance and Nearby Coastal Cities• Coastal / Southern Orange County• South San Francisco Bay Area • Berkeley
» Connectors » Destinations
• 100 stations –facilitate market growth (AB8)» Expansion of cluster, connector & destination station
communities » Develop new communities
} 23 stations

Hydrogen stations are:
• Public stations» Dispensers & storage equip added to existing gas
stations» Purpose-built stations (only for H2)
• Private stations for fueling company vehicles» Transit buses» Forklifts
On-site production Tanker delivery

Retail hydrogen stations
Harbor City• Retail fueling location• Gaseous H2 delivery• ~1200-1500 sq ft
footprint
Newport Beach• Retail fueling location• Onsite production (SMR)• Two dispensers on an
island under the canopy

Co-located hydrogen stations
Emeryville – transit & public fueling• Buses fueled inside fenced yard
» Hydrogen delivered as liquid• Cars access fuel from street
» Hydrogen produced using solar power

Renewable hydrogen stations
Fountain Valley • H2 from wastewater• 100kg/day of H2 for
vehicles• Produces 11% of the
facility’s electricity and provides heat for wastewater treatment

Station zoning, codes, & permitting• Primary permitting guidelines established:
» California Fire Code» NFPA 55 – Gaseous & Liquid Hydrogen Storage» NFPA 52 – Vehicle Fuel Dispensing
• NFPA 2 – Hydrogen Technologies Code» H2 safety» Installation & operation of H2 fueling stations» Associated hydrogen storage and repair facilities
• Typically, adding H2 fueling to existing station is “by right” process w/no zoning changes
