Drivers and Barriers
Lack of framework regulations for LNG on Land and rivers in the EU/Transportation of LNG on road, canals and rail still
not harmonized
Subsidies/tax exemption-reductions for LNG- Infrastructure build up
No harmoniezed standards for LNG/LCNG refuelling stations
No approved standards for on board equipment on vehicles
Small Scale LNG

Referent: M. Seifert, SVGW
Typical Small Scale LNG Total L-CNG stations in Europe: 30
CNG, mainly for Passenger
And Light Duty Vehicles
LNG, Heavy Duty Vehicles

Referent: M. Seifert, SVGW
The Landscape
The use of LNG as a vehicle fuel is one of the fastest growing sectors of the NGV industry
Rapid technical advances
Broad scope of possible applications:
- Heavy duty vehicles
- Rail locomotives
- Marine applications: Ship propulsion
But........
Very interesting for peak shaving
Key technology for satellite gas distribution systems
-
Referent: M. Seifert, SVGW
And the Key is
LNG transport on the road
LNG transport on ships (inland shipping)
LNG transport on rails
-
Referent: M. Seifert, SVGW
Standards
What is it.........Bloody Boring!!!
Who wants zo know about standards processes?
Who wants to participate?
But we need them for:
- The Authorities. Assist regulators/
ease approvals
- For Commissioning
- Maintaining safety and reliability
-
Referent: M. Seifert, SVGW
Standards
Permanent working in progress
Never finished
-
Referent: M. Seifert, SVGW
Safety considerations
Flammable Vapour: Thermal radiation from ignited LNG vapours/Explosions
Cryogenic fluid (T
-
Referent: M. Seifert, SVGW
Requirements for the use Containments: Primary containment with appropriate
materials and engineering design/Secondary
containment preventing leaks such that the area affected
is minimized
Minimize the frequency and size of LNG release and the consequences
Risk analysis
Detection of gas and fire
Safety concept with alarms
Emergency shutdown/equipment isolation
Hazardous zones (avoiding ignition sources)
Separation distances
Training
Maintenance

Fuel Quality Issues LNG
Ships engines especially dual fuel require constant quality, high purity, high methane number
LNG for safe and economic operation
For constant power to provide manoeuverability
Without engine knock (damage, efficiency loss)
While all other transport fuels are subject to strict specifications, LNG in general is not. There is a need
for LNG fuel standardization like in the USA (fuel
grade)
Think of EN standards for petrol, diesel, biodiesel, ... and EU Fuel Quality Directive. And what about
manufacturers warranties?
-
Referent: M. Seifert, SVGW
LNG Fuel Quality
Fuel Grade LNG: methane 97.0 mole % ethane 1.0 mole % total inert gases 2.0 mole % (US industry standard)
Experiences in countries like USA,
Australia, China, Japan, UK, Norway

Referent: M. Seifert, SVGW
Critical Issues for Small Scale
LNG
Risk analysis in a standardized form: 1. For the equipment
2. For the site specific aspects
Hazardous zones: Eex-document with safety distances
Internal and external safety distances
-
Referent: M. Seifert, SVGW
Still a long list of Critical Issues
-
Referent: M. Seifert, SVGW
And on top of that:
Self Dispensing of LNG
Multifuel Stations/Integration of LNG
Distances to other Fuels and their Dispensers
Storage Limits for Small Scale LNG
Blow Of Limitations/Use of Blow Off Gas
-
Referent: M. Seifert, SVGW
Summary Worldwide: The technologies for handling LNG are there
LNG production, transportation, unloading, dispensing technically solved, safe, reliable
Europe: Big issue LNG distribution infrastructure in continental Europe
Trend: Small scale LNG refuelling network
Trend: Small scale liquefaction, pipeline liquefaction
Trend: LNG first movers: ships
Barrier: Prices of equipment/Economics of transport/LNG prices at terminals
Barrier: Consistent normative and regulatory framework for LNG in general
