H2USA: Siting Refueling Stations in the Northeast

To achieve cost-effective deployment of both fuel cell electric vehicles (FCEVs) and hydrogen stations, the number of vehicles and public stations must grow together in areas of highest demand. This fact sheet introduces two advanced modeling tools and presents preliminary analysis of the hydrogen refueling station locations needed to support early consumer demand for FCEVs in the Northeast United States.

National Hydrogen Scenarios: How Many Stations, Where, and When?

This report examines development scenarios for hydrogen station networks needed to support a national rollout of fuel cell electric vehicles (FCEVs) in the United States. It was developed within the framework of the U.S. public-private collaboration known as H2USA, with approximately 50 partners committed to enabling hydrogen infrastructure for FCEV adoption. In this report, an internally consistent analytic modeling method simulates how station networks might develop across cities and regions, assuming that successful planning and coordination activities result in a rollout of FCEVs and stations similar to California's. These scenarios are not forecasts of future market outcomes. Rather, they provide insight to various public and private stakeholders engaged in the planning and coordination required to help facilitate their own station networks, while reducing hydrogen station investment risks.

Scenario Evaluation and Regionalization Analysis (SERA) Model: Demand Side and Refueling Infrastructure Buildout

The National Renewable Energy Laboratory's Scenario Evaluation and Regionalization Analysis (SERA) model estimates the number, size, and locations of hydrogen refueling stations that satisfy the fuel demand from fuel cell electric vehicles (FCEVs) and the hydrogen supply requirements to meet such a demand in terms of hydrogen production plants and delivery infrastructure. SERA simulates the systemwide cost-optimal evolution of hydrogen refueling infrastructure, providing insights that reduce the informational and financial risks associated with infrastructure investment decisions and helping accelerate the adoption of FCEVs. This report describes the SERA model's demand-side and refueling infrastructure buildout algorithms, and it also illustrates use of the model for simulating hydrogen refueling stations deployment scenarios using as an example the recent H2USA national hydrogen infrastructure report.

H2FIRST Hydrogen Contaminant Detector Task: Requirements Document and Market Survey

The rollout of hydrogen fueling stations, and the fuel cell electric vehicles (FCEV) they support, requires the assurance of high quality hydrogen at the dispensing point. Automotive fuel cells are sensitive to a number of chemicals that can be introduced into the dispensed fuel at multiple points. Quality assurance and quality control methods are employed by the industry to ensure product quality, but they are not completely comprehensive and can fail at various points in the hydrogen pathway from production to dispensing. This reality leaves open the possibility of a station unknowingly dispensing harmful contaminants to a FCEV which, depending on the contaminant, may not be discovered until the FCEV is irreparably damaged. This situation is unacceptable. A hydrogen contaminant detector (HCD), defined as a combination of a gas analyzer and the components necessary for fuel stream integration, installed at hydrogen stations is one method for preventing poor quality gas from reaching an FCEV. This document identifies the characteristics required of such a device by industry and compares those requirements with the current state of commercially available gas analysis technology.

H2FIRST Reference Station Design Task: Project Deliverable 2-2

This report presents near-term station cost results and discusses cost trends of different station types. It compares various vehicle rollout scenarios and projects realistic near-term station utilization values using the station infrastructure rollout in California as an example. It describes near-term market demands and matches those to cost-effective station concepts. Finally, the report contains detailed designs for five selected stations, which include piping and instrumentation diagrams, bills of materials, and several site-specific layout studies that incorporate the setbacks required by NFPA 2, the National Fire Protection Association Hydrogen Technologies Code. This work identified those setbacks as a significant factor affecting the ability to site a hydrogen station, particularly liquid stations at existing gasoline stations. For all station types, utilization has a large influence on the financial viability of the station.
