Hydrogen Fueling Background at Proton

• World leader in installed base of PEM electrolyzers– Over 30 fueling project installations to date

• Proton operates the only publicly accessible hydrogen fueling station on the East Coast (SunHydro 1)

• Operates a fleet of Toyota FCV’s as part of their pre-commercial test program

• Creating fully packaged solution for SunHydro working with leading equipment partners

• Developing multi-hundred kg/day electrolyzer platform to address commercial fueling markets

Why the commitment to FCV’s?

• Vehicle range:– Commercial FCV’s will have > 300 mile range

• Refill time:– Fast filling capability allows for 3 to 5 minute fills

• Hydrogen fuel enables renewable fuel pathways via electrolysis and reformed biogas

• The technology is proven, and the cost curves support consumer acceptance

• There is a commitment to buildout of hydrogen infrastructure in Europe, Japan, California, etc.

• ZEV MOU signed by 8 states provides a policy directive to put BEV’s and FCV’s on the road

California station development status:

54 station projects being tracked; 29 stations either open or approved to build!

SunHydro 2 Project: New H2 fueling capability in Washington, DC• Proton OnSite has developed a new compact “site ready”

station design, SunHydro 2.• In collaboration with DOE and NPS, this equipment design

will be demonstrated at the NPS site on Brentwood Ave.• The station will provide an important fueling capability for

FCV’s that will be used for outreach and market development efforts.

Novel Component Arrangements save space, cut cost

• Two 20’ containers separated by lightweight 2 h firewall• Class I Div 2 compression, storage, compression,

dispenser, chiller– Open top, bottom for natural ventilation; solid sides– Storage tubes protected by 2 h firewall panels

• Non-classified electrolyzer, power, control, cooler– Enclosed, ventilated, heated (water equipment)

SunHydro 2 Summary:

To fuel pending release of FCV’s• Small scale footprint and capacity

– 40’ ISO container integrated unit– Power and water in, H2 fuel out– Fuels 8 FCV/day or 3 FCV/hour– Onsite H2 generation – no resupply– 46 kg H2 total storage, ASME labeled

• Proven technology - repackaged• Meets NFPA, NEC standards

16

Large scale H2 production is ready to support commercial vehicle rollout:

1 MW prototype system integration completed and verification in process

M1 prototype on test, producing > 400 kg H2/day

Proton Strategy for Fueling Market• Continue product development to reduce capital cost and

improve efficiency of electrolyzer systems

• Support efforts for renewable fuel credits and other favorable policy initiatives

• Coordinate station development efforts with vehicle OEM market introduction plans

• Work with equipment integrators and station developers to provide on-site generation capability for renewable hydrogen

• Maintain position as world leader in electrolysis technology and electrolysis-based hydrogen for fueling applications
