Content
CNG Net & LNG 24
CNG Net > CNG Net is investing in a cleaner
future. > CNG Net carries out the
exploitation of a network of refuelling stations in The Netherlands.
> CNG Net designs, build, finance, maintain and operate the refuelling stations at own risk.
> CNG Net is a total solution provider.
Refuelling stations
> 57 CNG Net public refuelling stations
> 120+ CNG refuelling stations
> 2 LNG 24 refuelling stations > 10 LNG refuelling stations
in total
The role of standards > International accepted
safety level • minimal safety requirements • safety distances at refuelling station
> Standards are necessary to introduce a “new” fuel to get market acceptance
• clear specifications and test methods • no trade barriers caused by local
regulations
> To overcome international trade barriers
• refuelling coupling car/filling station
• pressure levels for LNG storage
> International certification of components and systems
• clear specifications and test methods
• no trade barriers caused by local regulations
International standard development
Establishment of PC 408
Establishment of PC 408
Goal EC
> Stimulate the introduction of biomethane
> A European Standard for biomethane to be used as fuel for vehicle engines
> TS or EN for biomethane to be injected into the grid
Scope PC 408
Upgrading
biogas from digestion
injection into the gas grid
Refueling station
Part 1 grid specification
Part 2:Automotive
Specification
biogas fromthermo chemical process
conditioning
Refueling station
Part 2 :Automotive specification
Natural gas Grid
Local dedicated infrastructure
Non-grid sourced natural gas
> first enquiry ended > reviewing the comments > four major challanges
> Wobbe range for L gas > Sulpher content > Methane number > Silicon levels

Chlorinated, Fluorinated compounds based upon health criteria
Values based upon Health Criterea
Injection group
Metals: Arsenic 0.0041 mg/m3 Barium 0.11 mg/m3 Cadmium 0.0034 mg/m3 Chromium (Hexavalent) 0.00014 mg/m3 Chromium (Total) 0.00054 mg/m3 Nickel 0.014 mg/m3 Organo-chlorides [1] 1.0 mgCl/m3 Organo-fluorides [2] 3.5 mgFl/m3 Total S [3] 14 mgS/m3
Inorganic compounds: Ammonia 5824 mg/m3
Aromatic compounds: Xylene 13989 mg/m3
Preliminary results > Risk Assessment Methodology,
bases upon European research carried out in UK (2012) and France (2008)
> Health criterea assement will be a separate Technical Report (TS)
> assessment /input needed from other European countries
research on Silicon > Limit values have to be set > report on behaviour of silicon for domestic
boilers > failure of ionization safety device > clogging of stainless steel heat exchangers > carried out in L gas situation
> research on behaviour of gas engines exposed to silicon > failure of spark plug > sensors performance like Lambda sensors > performance of catalist > Silica build up in lubrication oil
