SCHEMA OF LNG AND LCNG REFUELLING STATIONS
CNG versus LCNG machines
Compressor
290 Sm3/h, 90 kW Compressor
290 Sm3/h, 90 kW
LCNG Pump
600 Sm3/h, 20 kW
Larger civil works, area, building, operation, maintenance, noise, electricity consumption 100%
Open air installation, Cold end exchange 4 hours, electricity consumption 11%

MAIN ADVANTAGES OF LNG/LCNG TECHNOLOGY
• Dedicated LNG storage tank design • Low energy consumption in comparison with CNG machines
- LNG submerged pump - HP piston pump (up to 350 bar)
• High pressure ambient air vaporizers - no mowing parts = no maintenance - no energy consumption, heated by ambient air only
• CNG buffer & CNG dispenser are the same as atnormal CNG fueling station • LNG pump skid:
- continuously submerged pump in cold liquid = instant start - flow rate 190lit/min = very short refueling time of buses/trucks
• LNG Dispenser – MID approved flow meter/system
LNG + LCNG station Los Angeles, CA, USA (here as representation of around 100 stations delivered by CHART to USA, Australia, Korea and other countries
4 × 60 000 liter storage,

CAPACITY:
1670 Nm3/hr (in future 2500 Nm3/hr) 35 busses (future 55 buses)
Slow filling system
Original LNG bus manufacturer SOLBUS, Poland
Original LNG truck manufacturers
• Volvo FM Methanediesel 460 HP ; dual fuel 25% Diesel + 75% LNG ; 100 trucks in 2011 to UK, Sweden, Netherland
• Iveco Stralis LNG 270 HP (option 330 HP) ; 1000 km autonomy (much bigger than CNG). • Mercedes Econics, 279 HP, 1000 km autonomy. • 5000 LNG trucks and busses are in operation in USA.
Important progress in China and Australia. • UK – 300 vehicles now (80 last year), Coca Cola, UPS, Tesco ,
DHL, etc.
Examples of dynamics of business
• 250 LNG trucks implemented in the Port of Los Angeles transport systems • Chart has been getting orders for 400 LNG vehicle tanks in Europe for 2012
NGVA Europe supports LNG blue corridors strategy for dual fuel trucks Sufficient distance between LNG stations is 1000 km the European Commission highlights the importance of Liquefied Natural Gas (LNG) terminals to cover Europe's future increasing demand for natural gas. This estimation coincides with NGVA Europe's focus to promote a European NG/biomethane supply chain for long distance road transport via LNG Blue Corridors
Clean Energy (our customer) develops LNG blue highway corridors throughout USA

• Storage tank: 2x HT 500 m3 (total 1000 m3 gross volume) • Cryogenic pump: 1700 liter/min • VIP: DN150; 100 meters (under the ground) • Refilling of the ships (e.g. BergensFjord – Norway – 2x 125 m3) • Frequency of filling of ships – every night !
Main data for the filling terminal HALHJEM (Norway):
Filling module VIP interconnecting piping (bellow roadway)
Storage tanks – 2x HT500

LNG BUNKERING STATION
LNG is rapidly becoming more available. Sourcing for Central Europe
from liquefiers in Poland
from marine terminals
Ecological and economical solution
LCNG stations can improve CNG fueling infrastructure
LNG fueling time is comparable to diesel fueling time
ISO standards are under development. Existing installations have been accepted on the base of more general standards
Emission restriction for ships in harbors are driving force for marine applications (can be also applicable on inland water-ways).
CONCLUSIONS
FUELING CAN BE BORING OPERATION – DON‘T BE AFRAID….. :-)
