•Monitoring and analysis of world, regional, and local NGV markets (ongoing & update)

•Best Practices for NGV fuelling stations•Identify impacts of bio-methane on NGVs•NGV technologies to enhance efficiency•NGV for large fleets: economics and incentives

Best Practices for NGV refueling station Purpose & Scope

principals: Jeffrey Seisler (CFC) & Peter Seidinger (OMV)

Develop an understanding of cost reduction opportunities and ‘best practices’ for the

installation and operation of fuelling stations serving natural gas vehicles.

Sources & Resources

• General literature search & available industry information

• Personal interviews & discussions• Questionnaires surveying stakeholders

• Results reflect a blend of qualitative and quantitative information

Who were the target sources/recipients of the surveys?

• 60 experts worldwide surveyed• Suppliers of NGV fuelling stations; installers;

consulting engineers.

- 48% response rate and 14 reviewers of draft report

• Operators and customers of NGV fuelling stations

- 50% response rate and 15 reviewers of dreft report

• Some were in both categories (i.e. gas company installers who also run NGV fleets)

Respondents were stakeholders from five continents

FINDINGS*

*Summary is a microcosm of total findings & conclusions

Public petroleum fuelling stations are the benchmark for NGVs

Service• Open 24hours per day / 7 days per week;

• Acceptance of all credit cards/fuel cards;• NG-dispensers placed at same locations as

diesel/gasoline pumps;• Other non-fuel services

provided: food, beverage services, car wash, etc. (where the money is made!!)

Public petroleum fuelling stations are the benchmark for NGVs

Performance• Unquestionable safety standards (including

identifying differences between CNG and LPG.)• Fuelling time comparable to diesel/gasoline (not

more than twice as long)

• Highest possible filling pressure to ensure the best NGV range

• Station under all conditions to achieve 98-99% reliability including during peak times of fuelling. (i.e. Avoid queuing for fuel!)

Most important opportunities to reduce the cost of filling stations

Provider/ Suppliers• Don’t over-or-undersize but design for expansion • Modular design lowers cost due to standardization• Develop/improve & harmonize international

standards on NGV fuelling stationsCustomer/ Operators• Increase gas grid inlet pressure*• Reduce the cost to access the gas grid*• Shortest distance to hook-up station to grid• Development of international fuelling station

standards* MAJOR ISSUES & GAS COMPANY RESPONSIBILITY!!

Best PracticesUse LNG whenever possible

• Directly for L-NGVs and as L-CNG IF:• Reasonably priced LNG is available• Pattern of demand of L-NGVs and CNG vehicles fits the

pattern of customers’ needs, • Have sufficient base of NGV-fleet customers (existing or

new)!!

Most suppliers offer parts & components but some customers prefer ‘alternatives’

• Turnkey service is critical

• Downstream service is critical

• Some users want to cut corners with locally made parts

• May void warranty or result in poor quality
