Incentives to Close Revenue Shortfall
Incentives were split in two components: Production incentive
• Incentivizes good station placement & efficient operation
• Closes operating expense revenue gap
Capital incentive
• Reduces up-front cost barrier to market entry
• 50% reduction in capital expenses, tapering out by 10% annually after 2020.
• Applies on first time installations and upgrades

Multiple scenarios were produced internally – Two are articulated in this presentation
Baseline scenario (low vehicle sales) • Modest vehicle incentives (US & HI)
Optimistic scenario (high vehicle sales) • Full parity vehicle incentives • Lower cost fuel
Global inputs for both scenarios • Global hydrogen infrastructure source:
“Transport, Energy and CO2”, IEA 2009 http://www.iea.org/textbase/nppdf/free/2009/transport2009.pdf
• Station cost vs. cumulative infrastructure: NREL Hydrogen Station Cost Calculator (HSCC) 2012
• Vehicle cost vs. global deployment: “Transitions to alternative transportation technologies – a focus on hydrogen”, NRC, 2008 (temporal increase in market share Case 1 was used for all analysis)
Accomplishments: Scenario Analysis Provided
National Renewable Energy Laboratory Innovation for Our Energy Future 10
Key vehicle parameters were selected for ADOPT analysis
Fuel cell vehicle efficiency • Both scenarios use the following on-road, fleet average fuel efficiencies
• 68 mpg in 2015 • 72 mpg in 2050
Acceleration • 6.5 seconds for both scenarios (0-60 mph) • This may be somewhat optimistic, rationale is superior 0-40 mph electric
drive acceleration, and largely urban driving conditions on Oahu. Range
• 300 miles per full refueling
Average vehicle cost (sales-weighted, before incentives) • 2015 = $87,400 • 2020 = $35,600 • 2030 = $28,300 • 2040 = $28,500 • 2050 = $28,700
Accomplishments: Scenario Analysis Provided
ADOPT determines market share based upon price (cost minus
incentives and internal subsidies)

Price falls below ceiling due to market competition
Baseline scenario price ceiling targets parity fuel cost per mile with conventional gasoline vehicles (nominal price of gasoline for Oahu, adjusted by FCEV fuel efficiency)

Feedstock Costs: - Assumption that higher volume production results in lower cost hydrogen - Price of electricity = 24¢/kWh
Prescribed scenario feedstock & fuel price (Optimistic)
Accomplishments: Scenario Analysis Provided Optimistic scenario assumes a price ceiling of $8-$10/kg, which is a more competitive price than gasoline, stimulating market adoption

Two levels of vehicle incentives were used for scenario differentiation. More FCEV subsidies drive higher sales and improved station economics.
Incentive sources are not restricted to public subsidies: - Early adopter subsidization - Luxury market premium - “Green” premium - State & federal incentives - OEM subsidization Baseline: - Full parity with conventional platforms in early years - Incentives fade out by 2029 Optimistic: - Full parity with conventional platforms in perpetuity

Cash flow analysis inputs. Values are aligned with H2A assumptions
• Depreciation = 7 years, straight-line • Maintenance as % of contemporary station cost = 2.4% • Labor rate = $40/hr • Credit card fees = $2.5% (flow-through) • Property tax & insurance = 2% of cap cost • Interest on debt = 6% • Total tax rate = 38% • Sales tax = 8% (flow-through) • Sales & administrative expenses = 2% • Licensing & permitting = 1115 $/year • Rent = $3,400 • Total capital incentives through 2017 = 15% • Inflation rate = 0%*
• Target after-tax real IRR = 10% (return on investor equity) • Debt/equity ratio = 0.5 (target) • Cash on hand = 1 month of feedstock & utility expense (target)

Total vehicle incentives (Millions $)
Note: Incentives cover dispensing infrastructure only. No estimates are made at this time for finances of hydrogen production and distribution.
Note: Vehicle incentives continue to increase as total number of vehicles increases.

Production Incentives Sensitivity to Key Inputs
Accomplishments: Scenario Analysis Provided Sensitivity analysis of key cluster variables (Optimistic Scenario)
Model is fully integrated and can be used for risk analysis.
Note: Fuel efficiency is one of the most important parameters for infrastructure economics. It is however not shown in this specific sensitivity study.

Future Work
NREL completed the first phase of support for H2I, and no future work is currently planned. Modeling algorithms developed for H2I are being used for other hydrogen initiative locations Algorithms are being integrated into NREL’s scenario evaluation, regionalization and analysis (SERA) model. Additional model features to be added - Refinement of geographic dependence of station upgrading - Multi-region analysis (multi-state) - Explicit economics at the individual station level - Refine upgrade frequency (and cost) with industry input - Outputs module for communication with stakeholders
National Renewable Energy Laboratory Innovation for Our Energy Future 28
Summary
NREL produced a detailed deployment and financial model for Hawaii infrastructure deployment. The financial model has been used to analyze scenarios of stations and fuel cell vehicle penetration and presented to the Hawaii Hydrogen Initiative (H2I). Key findings: - Early coverage stations will experience low capital utilization - Station finances would need subsidies to support capital and
operational expenses - Debt and equity investments have a significant place in the early market
introduction and subsequent adoption
Future work: - NREL will continue refining and applying station infrastructure
algorithms to support future deployment initiatives.
