Projects & experience

GCNGSL have over 20 years experience in the Natural Gas Vehicle (NGV) field and their employees and partners have worked for many years on CNG related projects in the UK and overseas.

This experience includes running several departments within CNG refuelling business's (British Gas Vehicle fuels & CH Jones (KeyGas) Ltd ) which involved designing and building CNG refuelling stations, providing fuel and dealing with commercial aspects such as duty collection, and gas supply contracts.

GCNGSL also have experience from a supplier's perspective and have been involved in the design of compression plant & equipment and the maintenance of compressors and refuelling station equipment (CompAir UK Ltd). GCNGSL have worked on CNG projects in many overseas countries including Pakistan, China, Malaysia, Thailand, Korea, France, Germany, Switzerland, Holland, Tanzania, Nigeria and Kazakhstan.

GCNGSL have experience of all matters relating to Health & Safety of CNG systems including Risk Assessments, Written Scheme of Examinations (Pressurised Systems Directive), Auditing, Hazardous Area Analysis, ATEX & PED, DSEAR and National & International standards and regulations.

GCNGSL have participated in many seminars and exhibitions including presenting CNG papers at conferences in Malaysia, Pakistan and in the UK.



 GCNGSL do not just undertake CNG vehicle projects but they also have experience of high pressure gas projects such as extraction and compression of Coal Bed Methane (for vehicle use, power generation or gas mains injection), Biogas (land-fill, sewage or anaerobic digesters), and high pressure gas transportation through a "virtual pipeline" system (high pressure gas transported via road trailers for use away from the pipeline grid).

GCNGSL have a wide network of partners and associates who all bring additional experience and knowledge such that any gas related project would be considered.

Biomethane (Virtual Pipeline) transport and pressure reduction

Global CNG Solutions have also been working with Red Kite Management to provide Biomethane or CNG for the purpose of commissioning CHP units or Grid Entry units (gas-to-grid). We can supply large tankers of high pressure gas and a mobile Pressure Reduction system that takes the 250 bar gas down to the gas pressure required for the equipment, e.g. for CHP's this is normally 150 mbar to 200mbar and for gas to grid this can be 1 bar to 7 bar depending on the line pressure we are injecting into. 

 Example 1: Gas-to-grid (major gas companies)

We supplied CNG trailers with 250 bar biomethane and a mobile Pressure Reduction System to several sites, and supplied gas at 100-200 m3/hr at 2 to 8 bar to a Network Entry Facility 



Example 2: Landfill gas CHP

We supplied a CNG trailer with 250 bar biomethane and a mobile Pressure Reduction System, and supplied gas at 100 m3/hr at 150 mbar to a CHP engine on a Landfill Gas site. We also provided biomethane to an existing on-site PRS for commissioning purposes.



Example 3: AD plant commissioning

We supplied a CNG trailer with 250 bar biomethane and a mobile Pressure Reduction System, and supplied gas at 50 m3/hr at 150 mbar to an existing AD plant to commission the gas bag.

We also commissioned an AD plant using a temporary large gas bag (main digesters were still under construction)


 We also commissioned a standalone CHP engine before any of the AD plant was constructed (allowing the customer to lock in the RHI tariff and get financial approval for the construction phase)



Example 4: Industrial CHP commissioning

We supplied a CNG trailer with 250 bar biomethane and a mobile Pressure Reduction System, and supplied gas at 50 to 250 m3/hr at 100 to 200 mbar to an existing Industrial CHP. These sites were existing gas grid connected but now will be taking biomethane by virtual pipeline trailers.


We also commissioned a large Industrial AD plant which had a trailer filling system (virtual pipeline biomethane for remote daughter station off-load sites)
